Research aboard E/V Nautilus may assist in the search for extraterrestrial life, as exploration of hydrothermal vent systems informs the design of future science-focused missions across our solar system! In 2018, the SUBSEA (Systematic Underwater Biogeochemical Science and Exploration Analog) team launched their first field program, supported by NASA’s Science Mission Directorate and NOAA’s Office of Ocean Exploration and Research, to explore iron-rich hydrothermal vent systems on Lō‘ihi Seamount off Hawai’i.
As the 2018 expedition wrapped up aboard E/V Nautilus, Lead Scientists Dr. Darlene Lim of NASA Ames and Dr. Christopher German of Woods Hole Oceanographic Institution shared their insights into the future of ocean worlds research with Lead Science Communication Fellow Jenny Woodman of Proteus Science Communication. Catch up on the team’s findings in this conversation, and learn more about the 2019 SUBSEA expedition to explore Gorda Ridge, an active hydrothermal vent system that departs from the convention of black smoker hydrothermal systems, instead emitting clear fluids from the seafloor.

It is cold and dark. Creatures here have adapted to live and thrive in this environment, but not us. Once you pass the threshold of the aptly-named twilight zone, around 650 feet, there isn’t enough light to fuel photosynthesis. For every 33 feet of depth gained, the pressure increases by 14.5 pounds per square inch or psi; at a certain point, most organisms with gas-filled spaces, like our human lungs, would be crushed. As you continue to travel farther down, the weight of all the water above and around you presses in, making it impossible to pass a certain point without specialized technology. Most humans will never experience these mysterious depths firsthand. With the aid of submersibles, only three people have ever ventured to the deepest point in the ocean, the Mariana Trench, seven miles below the surface. The challenges of reaching this hadalpelagic zone make it one of the least studied locations on Earth.
I’ve talked to experts, visited their labs and research centers, and watched them at work–often under challenging circumstances. I’ve been to sea and shared the joys of science and discovery alongside bouts of seasickness, equipment malfunctions, and precious time away from loved ones. Few things I’ve experienced in 46 years on this planet compare to going someplace no human has ever gone before, to seeing this other world that exists right here at home.
Until we get out there and start poking around, we have no idea what we might find, but, according to NOAA, “More than eighty percent of our ocean is unmapped, unobserved, and unexplored.
I’m a writer and an educator. I’m also lucky to be able to say this: I am an ocean explorer.
Having spent the last two summers at sea, observing a wildlife survey in National Marine Sanctuaries on the NOAA Ship Bell M. Shimada and supporting robotic exploration of the deep sea aboard Robert Ballard’s Exploration Vessel (E/V) Nautilus, this is what I’ve learned: the Earth’s ocean is vast with many secrets waiting to be discovered.
Just a few months ago, in October, while exploring off the coast of California near Monterey, the E/V Nautilus team was moving their robotic explorer or ROV (which stands for remotely operated vehicle) down the flank of a seamount and out of nowhere they happened upon a brooding site with thousands of octopuses in shimmering water that indicated hydrothermal activity of some sort. No one has ever seen anything on this scale before. This real-life octopus garden is just one example of the discoveries waiting for us in our ocean.
To get a sense of scale of the discoveries still possible, consider the 2010 Census for Marine life. It took a decade to complete and was conducted by 2,700 scientists from over 80 countries, on 540 scientific expeditions, at a cost of $650 million dollars, U.S. They identified over 6,000 potential new species and published more than 2,600 research papers. The project shed light on a variety of ocean science research–from a white shark cafe in the open ocean to enormous microbial mats, “ranked among Earth’s largest masses of life.”
The census represents a monumental bit of discovery. Yet scientists, like Chris German from Woods Hole Oceanographic Institute (WHOI), think we’ve only scratched the surface. While off the coast of Hawaii last summer, German pointed to the Pacific Ocean, noting that it covers half of the planet and is “woefully unexplored.” He’s been studying hydrothermal vent systems just along the mid-ocean ridge for 30 years. The mid-ocean ridge is a ribbon-like mountain range that runs through the entire global ocean; it is about ten miles wide and 37 thousand miles long.
German estimates that the oceanic community has made discoveries at a rate of one new species every two weeks during his 30-year career. Even exploring as fast as they can go, they’ve only been able to explore about 20 percent of the mid-ocean ridge in three decades. He and his colleagues see opportunities to expand our capabilities here on Earth with emerging technologies in development for future space missions. Essentially, our drive to reach outer space and other ocean worlds will unearth much in unexplored regions of our ocean.
The oceanic and space communities have a great deal to offer each other–from technology development to protocols and training for remote work in extreme environments. In fact, scientists like Julie Huber believe it is time for the oceanic community to be more like NASA. Huber is an expert in marine chemistry and geochemistry at WHOI. Her work examines microbial communities in the deep ocean and, in the not-so-distant future, on other planets.
Huber argues: if NASA can land a scientific laboratory on Mars, then we should be able to do the same here on Earth. Sending scientific vessels to sea or space is no small feat. Ship time and space launches are costly and hard to come by. However, advances in marine robotics, such as Monterey Bay Aquarium Research Institute’s (MBARI) environmental sample processor (ESP) make it possible to do much more with less. When loaded onto an autonomous underwater vehicle, the ESP is a lab-in-a-can, collecting samples and processing them in situ for near real-time oceanographic monitoring. Huber advocates for developing new technologies, similar to MBARI’s ESP, that would allow for analysis of microbes in extreme environments like the deep ocean.
Huber is part of a program called NASA SUBSEA, which stands for Systematic Underwater Biogeochemical Science and Exploration Analog. The SUBSEA team members come from NASA, NOAA, the Ocean Exploration Trust, and several academic centers, including WHOI and Idaho State University.
In August and September, I served as the lead science communication fellow on board the E/V Nautilus during the NASA SUBSEA expedition to the Lōi`hi Seamount off the coast of Hawaii. The SUBSEA team is planning for future remote deep-space exploration of Europa and Saturn’s moon Enceladus as well as crewed missions to Mars and our own moon.
Robotic dives at Lōi`hi offered the opportunity to practice and develop protocols for future missions because today’s ocean explorers work remotely, using tools and methods that will serve space exploration. Someday, when we reach distant ocean worlds, we will deploy robots and explore from the safety of a command center here on Earth, a spaceship, or some other location like a base on the moon or an asteroid.
In order to prepare for those future missions, NASA and their partners gathered a science team at the Inner Space Center at University of Rhode Island’s Graduate School of Oceanography. This team remotely directed our operations on the E/V Nautilus while we were in Hawaii, serving as “mission control” for the expedition. Experiencing time-delays and technical difficulties will enable NASA and their partners to be better prepared for the challenges of deep space exploration.
Conditions at Lōi`hi, which is an active underwater volcano, are similar to what scientists believe exist on these other moons in our solar system.Lōi`hi was selected because the lower temperatures (about 390 degrees F) at these hydrothermal vent sites, called white smokers, are similar to temperatures detected by the Cassini spacecraft at Europa. Using ROVs, we collected rock and water samples so astrobiologists in Huber’s lab at WHOI and geologists from Idaho State could determine what sorts of rock and water interactions are taking place.
In places where sunlight doesn’t reach, there is no photosynthesis for food production. So, organisms like the microbes we observed and collected at Lōi`hi are make a living off of chemical reactions. Scientists are studying these reactions in order to model what could be happening on other planets.

To Darlene Lim, NASA Geobiologist and principal investigator for the SUBSEA program, the impetus to explore is an insatiable curiosity about what might be waiting out there. Lim has spent the better part of her career running teams and research in extreme environments on Earth, using them as analogs for future exploration elsewhere in our solar system and beyond.
“We have a sample size of one,” said Lim. “We know that this planet is habitable; we know it is full of life, but what else is out there?”
She adds that we have, at our fingertips, the opportunity to go and in situ understand whether or not life is beyond this planet in our solar system. She smiles and becomes animated when she talks about exploration, making her enthusiasm highly contagious. It’s hard not to get excited about answering questions humans have been asking for all of our brief history on Earth. “What an exciting endeavor that I think we should to take the opportunity to stretch out and accomplish,” said Lim.
But what will it be like when we actually get to one of these remote, distant places in our solar system? Will we find life?

Imagine you’re flying over an ocean world, not Earth but another. Maybe this is Europa, one of Jupiter’s moons. It is cold and inhospitable. But, scientists know there is an iron core, a rocky mantle, and a salty ocean. How do they know this?
Take a look at the composite image below. There are plumes of water vapor at about 7 o’clock. To identify these plumes, scientists used Hubble’s imaging spectrograph, an instrument which acts like a prism revealing a sort of wavelength fingerprint of the object being observed; this fingerprint makes identification possible. Using this instrument, they were able to capture the silhouette of Europa as it passed in front of Jupiter and identify these plumes of water vapor, rising over 62 miles above the surface. These data aligned with previous observations from Cassini flyovers of Europa and they indicate the presence of an ocean and geologic activity worthy of exploration.

When we do get to Europa, there will be no humans on the mission. In the coming years, we are going to overcome incredible engineering obstacles in order to land robotic explorers on a distant icy moon, over 390 million miles from home.
According to German, experts think we can get there by 2033. Then, once we’ve landed on the surface of Europa, it will take another two years to drill ten to fifteen miles through the ice in order to eventually make our way to the ocean floor and transmit images home to Earth–images that these scientists hope will include hydrothermal vents and microbial mats.
Lim said it generally takes 18 to 24 months to be able to draw meaningful conclusions from the fieldwork that took place at Lōi`hi, but she says everything is on track. This means I can’t really tell you exactly what was learned last summer, just yet, but I can attempt to convey why the work is so cool. While we were still at sea, I asked Lim and German why would we should travel 390 million miles to find tiny microbes.
“Any time that humanity has extended itself in that way, along comes other developments. Think social developments–the way we think about ourselves, we organize ourselves, what we think is palatable in terms of the way we treat other people,” said Lim. “It kind of comes hand-in-hand with the ability to think about what is beyond us.”
To German, 390 million miles, when considered alongside the vastness of space, isn’t really that far to travel at all.
“Rather perversely, what’s really exciting about it is only having to go 390 million miles for what we can do is ridiculously close to home,” said German. “And that’s completely new thing in the last decade.”
He goes on to explain that when we thought of looking for life elsewhere in the universe, we traditionally thought about looking for planets with liquid water on the surface and the kind of life forms that we understand from photosynthesis, the dominant form of life on our own planet.
To German, the current generation of ocean exploration work has revolutionized our view of what it takes to make planet habitable. The discovery of seafloor hot springs and cold seeps like those found along the California Borderlands have offered what German describes as a “panoply of different kinds of habitable environments that are often independent of sunlight.”
He’s quick to point out that on our own planet, we know that single-celled life was the only thing in town for the first two to three billion years of our history. “If an alien had ever come searching for life on our planet, there’s a two-to-one chance that all they would have found was an ocean full of microbial life and a barren landscape,” said German.
German believes that we could find microbial life in one or more of about half a dozen candidates in our solar system, in places with an ocean with geologic activity like Europa. German adds with zeal, “It’s closer to home than human-made robots have already been. We don’t even have to go to the limits of human ambition!”
During the 2019 expedition season, the SUBSEA team will be returning to the E/V Nautilus and diving at the Gorda Ridge in late May and early June–you can follow along from home by watching the live-streamed dives. The ridge is another volcanically active area off the coast of Southern Oregon and Northern California with temperatures and conditions similar to Lōi`hi.
The team will do much of the same science–looking at how the rock and water interactions support microbial communities–but they will also introduce communication breaks to simulate planned and unplanned communication drop offs.
It will be wonderful to see what we learn from this work and subsequent projects. To me, what is truly exciting is that ocean exploration here on Earth will eventually give us the tools to visit other ocean worlds. In return, our drive to explore the universe will allow us to better understand our home planet – to locate majestic underwater mountains, identify new medicinal resources, and discover sea creatures that defy imagination. And, after spending time with scientists like Lim, German and the SUBSEA team, I see that the opportunity to extend ourselves beyond the boundaries of what we currently understand about science, technology, engineering, and even ourselves makes a more-than-compelling case for exploration.
Until we get out there and start poking around, who knows what we will find?

Dear 2nd Graders,
I really enjoyed speaking with your class this morning. It is always fun to tell people about the work we are doing on board the Exploration Vessel (E/V) Nautilus, a 211-foot science vessel outfitted for exploring the ocean floor with robots and studying what is happening in our planet’s ocean.
After we ended our talk with you, one of your comments stuck with me. Your teacher asked me to speak about what girls do on our ship, adding that you all thought only boys could be engineers and that made me a little sad.
As a matter of fact, I couldn’t sleep for quite some time even though it was 4:30 in the morning here off the coast of Hawai`i. But, I woke up with a plan: I’d gather all the girls on our ship (there are a lot of us) and take a photo for you. I thought maybe if you saw how many girls are out here doing exciting work, you might start to see how many important things get done by both boys and girls.
But there was one really big problem…

All the girls working on the Nautilus are very, very busy. Eighteen members of the 31-person science team on the Nautilus are women. We serve in all roles — from engineering to communications, from the very highest leadership position down to our student interns. There is no place on the Nautilus where women do not work incredibly hard.
I went to the back deck of the ship where Wendy, Jess, and Antonella were busy repairing our robots, Hercules and Argus. Without these robots, (we also call them remotely operated vehicles or ROVs) we wouldn’t be able to travel to the ocean floor to learn about volcanoes, octopuses, sharks, and creatures no one has ever seen before. As ROV pilots, a big part of their job is maintaining and fixing the ROVs – Wendy, Jess, and Antonella are engineers, so they are really good at what they do!
I ducked around the corner and up the stairs, following Mary and Nicole, but it turned out they were busy too. A camera needed fixing, and as video engineers, they needed to tackle the job. Cameras are very important to the work happening on the Nautilus; they are like eyes on the robots and they help the pilots to safely move around; cameras also record all the amazing images from places humans can’t safely go. As a retired journalist and video engineer, Mary has lots of experience to help guide and train Nicole who just graduated from college.

Our science data team — Leigh and Megan were also quite busy. They spent part of the afternoon brainstorming how to manage the thousands of images and samples being gathered with each dive, and they met with expedition leaders to share their ideas about how to do even more with the limited space available for so many scientists on the ship.
Then, I went to the wet lab, but another member of the science data team, Brianna, was busy organizing the equipment the science team uses after Hercules collects those samples and brings them back to the ship; one of her jobs is to prepare those specimens for scientists all over the country to study back on dry land.

I ran over to the social deck, just in time to see Elizabeth rushing off to her lab. She had to place a bottle of seawater in an incubator, which is like a small oven. She wanted to test how long it will take her to process the samples Hercules will bring up to the ship from the volcano.
I was sure I’d be able to wrangle Sam and Nicole, but as part of the leadership responsible for the success of this and future expeditions, they were busy coordinating the hundreds of items that need addressing each day.

My friends Ariel and Mugdha were also busy, shooting video to help tell the story of science, ocean exploration, and marvelous feats of engineering.
Even I had to stop and take a break from writing this letter to you; Amy and I were needed in the studio where you saw us this morning. We had to talk to a group of people gathered at a museum in San Francisco – we showed them pictures and answered their questions just as we answered yours.

My last stop on this adventure was the lounge where Darlene was sitting at her laptop on a big leather sofa. As principle investigator for this project, her days are really long – she’s working even when she looks like she might be relaxing. When I found her, she was getting ready to go on NASA TV and talk about the work we are doing; two million people tuned in to watch her today!
I’m writing this letter because I’d hate to think that there are any young girls in your class who think it isn’t cool or possible for them to build robots or rockets, and I’d hate to think that there are boys who think they shouldn’t do the thing they dream about doing, whatever it may be.
Following science out to sea has taken me to some pretty extraordinary places. Image Credit: Jenny Woodman
And, if you don’t want to be a scientist or engineer, but you love the sea creatures — if you dream about what it might be like explore the ocean, I have a secret for you: not everyone involved studying the ocean is a scientist or engineer. I’m a writer. My job is telling true stories about this work so people can better understand the world we live in. Folks like me — anthropologists, painters, teachers, filmmakers, chefs, and all sorts of people play a big part, making amazing things happen every day for organizations like the Nautilus!
Thanks for asking us such smart questions. I hope you will stay curious, have fun and keep exploring!

On August 21, a team of scientists, engineers, and students arrived in waves, loaded with personal gear and equipment for deep sea exploration off the coast of Hawaii. The mission, a joint project with NASA, NOAA, Ocean Exploration Trust and a number of academic institutions, is to explore the Lōihi Seamount with remotely operated vehicles, or robots.
Conditions at this underwater volcano are similar to what scientists believe exist on moons in the outer regions of our solar system. Experts from NASA’s Systematic Underwater Biogeochemical Science and Exploration Analog (SUBSEA) team think it is likely that oceans and hydrothermal activity exist beneath an icy crust on Saturn’s Enceladus and Jupiter’s Europa.
Robotic dives at Lōihi also offer the opportunity to practice and develop protocols for future missions. Someday, when we reach distant ocean worlds, it is unlikely that humans will be able to enter into these hostile environments; it is more likely that they will deploy robots and explore from the safety of their ship or some other location, much like ocean explorers do today.
In order to develop protocols to guide those future missions, NASA and their partners have gathered a science team at the Inner Space Center at Rhode Island Graduate School of Oceanography; this team will remotely oversee and direct operations on the Exploration Vessel (E/V) Nautilus here in Hawaii. The work will serve as an analog for expeditions where astronauts will communicate across great distances. Experiencing delays and possible technical difficulties first-hand on Earth will enable NASA and their partners to be better prepared for the challenges of deep space exploration.
Back on board the Nautilus last Monday, there were hugs and laughs as those who had sailed on the ship reunited and newcomers were introduced. We were eager to get going, but Hurricane Lane had other plans. The storm intensified and the Coast Guard ordered all ships over a certain size out of the port of Honolulu. Nicole Raineault, vice president of exploration and science operations for the Ocean Exploration Trust shared the news that expedition leaders and the ship’s captain, Pavel Chubar, didn’t feel the science team would be safe on board the ship during the storm. The Nautilus was going to ride out the weather in safer waters north of Maui, but the seas would be rough nonetheless – it was not going to be a place for non-professional mariners.
On Wednesday August 22, we repacked our gear, secured science equipment on the ship, and offloaded in Honolulu. As stores and restaurants closed all over Waikiki where we were staying, it was surreal to see the images of an immense storm heading our way while tourists poured in and out of the shops. The island chain is no stranger to powerful storms, but the last major hurricane occurred in 1992; Hurricane Iniki caused $3.1 billion in damage.

Lane was expected to hit Hawaii on Friday or Saturday, so we stocked up on food and water in case the storm disrupted power and transportation. (Experts recommend your family’s disaster supplies include one gallon of water per person, per day as well as enough food, medicine, and creature comforts like activities for little ones to last at least two weeks. For more on how to prepare your family for disaster visit here and here.)
The slow-moving storm never made landfall on O’ahu, but caused catastrophic flooding to the Big Island, dumping over 50 inches of rain in just a few days.
On August 26, we were transported to the Nautilus via water taxi and immediately set off as teams worked to prepare equipment for operations on Monday morning. The seas weren’t quite as calm as most would like and many napped and stared at the horizon in an effort to quell uneasy stomachs. Most over the counter motion sickness medicines cause drowsiness (and mine was no exception — although the box was labeled “less-drowsy,” it would be more apt if it read “may cause light coma”).

We’re now our way to the Kilauea lava flow, a slow-moving eruption that has caused extensive damage to the Big Island since early spring. Data from the previous Nautilus expedition, Mapping Pacific Seamounts, included signals that look like little bubbles, which they’d never seen before.
Chris German is a senior scientist at Woods Hole Oceanographic Institute and leader of the science data team for this expedition. “It is a process we’ve not had the chance to study previously,” German added as he explained that they are returning to the same spot in order to see if those mysterious bubbles are still present.
He and his team are eager to determine an ideal location future dives. The Nautilus team uses sonar mapping technology to both enhance our understanding of the processes occurring on the ocean floor and to accurately identify where to deploy the robots for exploration. “This may be another kind of hydrothermal system nobody’s ever seen before,” German added with a grin.
We expect to be able to see the flow area from a distance after breakfast Monday morning, and we’re looking forward to launching our first dive operation on the Lōihi Seamount at midnight (HTC) Tuesday morning. Whenever the robots are deployed, the video feed is live-streamed to viewers all over the world at www.nautiluslive.org.

In a breeding season and field season that has been a tough one for both the Black Guillemots on Cooper Island and the investigators studying them, today was a day of celebration as morning nest checks revealed that the oldest nestling on the island had departed for the sea during the night.
The first fledge of the year is always exciting since it is an important benchmark in our field season, which begins with recording the owners of nest sites and continues with observing the dates of egg laying and monitoring the hatching and subsequent growth of nestlings. While it is the parent birds who get all of the credit for a successful nesting season, we cannot help but feel some satisfaction having monitored daily the details of their three-month reproductive cycle. Additionally, and certainly now with the recent decline in the size of the colony, a fledged chick provides hope for the future. With sufficient luck, in three years the chick that fledged last night will return to Cooper to join the breeding population.
So we congratulate the proud parents White-Black-Gray, a bird fledged from Cooper Island in 1995 who has bred here since 2000, and Blue-Blue-Yellow, an immigrant (likely from one of the large Russian colonies) who had been breeding on the island for the past twelve years.
We are hoping that in the next few days their now independent fledgling will be joined by its sibling and a good number of the 50 birds that remain in nest sites.
This field report is part of an ongoing series titled Arctic Change centered around George Divoky’s 44th field season studying Black Guillemots, sea ice, and climate change on a remote Arctic island off the coast of Alaska.

I stood on the sidewalk swaying on solid ground, a phenomenon dubbed “dock rock” or “land sickness” by those who’ve spent time on boats. I looked over my shoulder at the big blue and white ship from which I had just disembarked with my usual grace and style. High tide made the gangway incredibly steep; I lost my footing and slid all the way down with my gear to the chorus of onlookers gasping.
After being at sea, a combination of exhaustion, adrenaline, and homesickness fueled a multitude of feelings. With a lump in my throat, I thought I might never get the chance to do something so unbelievably cool again. I had just spent two weeks with truly amazing people exploring the ocean floor – with robots.
Last summer, I served as a science communication fellow on board the Oceanographer Bob Ballard’s Exploration Vessel (E/V) Nautilus.
Our expedition took place in Cordell Bank National Marine Sanctuary. The 1,296 square mile sanctuary had nearly doubled in size since receiving its designation as a protected place in 1989. Prior to the expedition, the scientists responsible for managing the sanctuary lacked the resources to fully explore and understand what lived on the ocean floor, miles below the surface. We traveled along the Continental Shelf, exploring underwater canyons and steep cliff faces, collecting video footage and samples that were sent to hundreds of researchers around the country.
These observations were aided by two remotely operated vehicles (ROVs), or robots, named Hercules and Argus. The ROVs work in tandem, tethered to the ship and each other. Argus absorbs the ship’s movements and shines bright lights down on Hercules as it performs delicate maneuvers and operations below. Hercules is outfitted with multiple high definition cameras, a Kraft Predator arm, and a host of sampling tools that aid the Nautilus team in their mission to explore the biology, geology and archeology of wild and unexplored places in the ocean.
Whenever the robots are deployed the video is live streamed all over the world, allowing students, scientists, and fans to explore with the team. This technology takes humans to locations too costly, distant, and dangerous for in-person observations like active underwater volcanoes and hydrothermal vents.
Using the Nautilus’s technology and expertise in Cordell Bank, NOAA scientists were able to identify new deep sea habitats teaming with life. There were jellies, sharks, skates, and over 40 species of rockfish, swimming among deep sea corals and sponge communities – it was a remarkable experience from beginning to end. And, it turns out that last summer was not the last time I’d set foot on the Nautilus.
From August 20 to September 13, I’ll rejoin Ballard’s Corps of Exploration as lead science communication fellow for a joint mission with NASA, NOAA, and various academic centers. The expedition is part of a multi-year SUBSEA (Systematic Underwater Biogeochemical Science and Exploration Analog) Research Program.
We’ll be exploring the Lō’ihi Seamount – an active underwater volcano off the coast of Hawaii. The hydrothermal venting and geologic features found at Lō`ihi (sounds like low-ee-hee) are thought to be similar to what scientists expect to find on other, distant, ocean worlds. We will be testing equipment and protocols as well as collecting samples and video to learn more about this geologically active and unique environment.
NASA is watching how the oceanographic community works in unusual environments in order to develop protocols for space exploration. When astronauts eventually make it to distant planets, it is unlikely that they will be able to land their spacecraft and walk on the surface right away. Using robotic technologies similar to what is used in ocean science, those astronauts will conduct their observations from the relative safety of their spacecraft – just like many ocean explorers here on Earth.
In order to allow a very large team of scientists and collaborators to participate from land, most of our dives will run from midnight to 4 p.m., Hawaiian time (HST). You can follow these dives online at www.nautiluslive.org and updates will be posted regularly on the Nautilus’s Twitter feed.
I’ll be standing watch from midnight to 4 a.m. and noon to 4 p.m. – moderating the questions coming in from the audience and helping translate the complexities of this work whenever the robots are deployed.
Last summer, I had no idea what to expect as I nervously put on my headset and sat down at my station for my first watch shift. Over the subsequent hours and days, I learned about the science and biology of the deep ocean and the technology and teamwork that took us to this otherworldly place. I saw my first octopuses in the wild, graneledone boreopacifica, who brood their eggs for 4 years, and I learned that skate egg pouches are called mermaid’s purses. As I prepare to head back out, the work is more familiar, but I’m just as eager to see new and exciting wonders.
I hope you’ll come along and explore this blue planet with us!

Common Murre are abundant here; many can be seen carrying fish on a return flight to the Farallon Islands, where hungry babies eagerly wait for their next meal. The islands — uninhabited by humans except for a small group of scientists — are nesting grounds for thirteen species of seabirds and six species of marine mammals that breed or haul out on the islands each year.
According to U.S. Fish & Wildlife service, the Farallons host the largest seabird nesting colony south of Alaska with numbers greater than 350,000 in the summer, including nesting Common Murres, Tufted Puffins, Pigeon Guillemots, and Western Gulls.
Just 27 miles west of San Francisco, these rocky islands weren’t always an ideal habitat for seabirds. During the California Gold Rush, a lack of agricultural infrastructure led hungry prospectors and entrepreneurial foragers to the Farallons for eggs, which pushed the Common Murre to the brink of extinction.
Over the years, a combination of exploitation from hunting and foraging to military uses left the island in a state of disarray. Feral cats and nonnative rabbits introduced by previous inhabitants obliterated many seabirds. Oil spills and pollution also took a toll on the habitat, which was established as a national wildlife refuge in 1909 by Theodore Roosevelt. Since the late 1960s, partnerships between U.S. Fish & Wildlife, NOAA, and Point Blue Conservation Science have helped to restore and maintain the Farallons for wildlife and research.

We’re here on the second day of an Applied California Current Ecosystem Studies, or ACCESS, cruise. It is part of a long-term effort, now in its 15th year, to monitor and understand the oceanographic conditions, prey availability, and abundance and distribution of seabirds and whales in the region.
The data collected on these cruises, which take place three to five times per year, are used to help inform decision-making and research priorities in Northern and Central California National Marine Sanctuaries. ACCESS is a partnership between NOAA National Marine Sanctuaries and Point Blue Conservation Science.
Seabirds and marine mammals are drawn to the region by a process called upwelling. In the spring, strong winds move across the surface of the ocean circulating and drawing cold, nutrient-rich water from the deep ocean areas that lie below the edge of the Continental Shelf and Slope. This process is part of what makes these waters, according to NASA, “some of the most biologically productive in the world.”
When these nutrients reach the sunlight at the surface, the perfect environment is created for marine plant life — from phytoplankton to kelp forests. The plants, in turn, feed the wildlife.
Krill thrive in these nutrient-rich waters. “Its size is tiny, but its significance is colossal,” Mary Jane Schramm writes. “Krill – a shrimp-like crustacean – forms the basis of the marine food web for whales, seabirds, fish, squid, seals, and sharks throughout the world’s oceans.”
As we zigzag along the coast via predetermined transect lines, this productivity is evident in both the variety and quantity of life seen here.
The expert wildlife observers are armed with details to make each sighting even more exciting. When prompted, Dru Devlin, research associate for Greater Farallones Association, offers up a litany of fascinating details about the Common Murres, which nest on steep, rocky cliffs.

The female lays one large blue egg, which she sits on for the duration without nourishment. When the egg finally hatches, she takes off to replenish her strength for whatever lies ahead and the father steps in to take care of the baby chick. (In Far from Land: The Mysterious Life of Seabirds, Michael Brooke points out that seabirds generally only produce one to two eggs per year, which he adds is smart evolutionary strategy, because otherwise the ocean would be full of birds with nothing to eat!)
Murre chicks leave the nest, before they’ve fledged, meaning they haven’t grown flight feathers. When the time comes, the father and chick leap off the steep cliff and into the water below where the little one floats for up to two months, waiting for its flight feathers to come in.
Yesterday, we heard a cacophony of bird calls throughout the day; Devlin explained that we were hearing the father birds calling out to their chicks as they returned from fishing for food. Devlin concludes her explanation by asking me to imagine what it must be like to look for your baby in the midst of rough seas and large swells and I find myself, once again, awestruck by the tenacity of seabirds.

In a very short period of time, I’ve seen so much. As a city kid from Philadelphia, my encounters with animals outside of zoos were limited to squirrels and pigeons, so much of these sightings are pretty big firsts for me. While everyone was busy deploying equipment on a side deck after breakfast, I ducked around a corner for a quiet moment and found myself alone with a pod of Pacific white-sided dolphins, playfully lingering alongside our vessel.
Observing these creatures is a rare treat made even better when accompanied by a team of biologists and wildlife experts to explain what I see and fill me with a sense of wonder for new favorites like the uncommon Common Murres.

In the Arctic, much depends on ice. Pack ice. Drift ice. Old ice. New ice. For some wildlife, ice provides safe haven from predators and for others, it offers access to prey. For humans, many of whom are living in isolated coastal communities with no roads in or out, ice is everything.
Sailors and explorers have kept sporadic records about ice conditions dating back thousands of years, but only since 1979, with the launch of Earth observing satellites, have streams of near-constant information about Arctic sea ice been available. Using images and observations captured daily, scientists are able to measure ice thickness, area of coverage, and seasonal fluctuations in the advance and retreat of ice coverage.
Real-time sea ice images and data are vital for the safety of researchers like George Divoky and for people in Arctic communities who depend on ice for subsistence hunting and fishing. Anthony Fischbach is a wildlife biologist for the United States Geological Survey (USGS) in the Alaska Science Center Walrus Research Program, where he has worked since 1994. Fishbach delivers a daily “Ice Mail” to just over 100 people interested in up-to-date information on Arctic sea ice. Subscribers include Divoky, scientists in Russia, and remote Inuit communities who may not have easy access to internet connections capable of retrieving large amounts of data.
“The main niche I’m trying to fill is a way to get meaningful sea ice imagery and charts in the palm of your hand or on the deck of a ship where you’ve got really minimal bandwidth,” said Fischbach. “If you’re in a remote community that has 2G cell phone connection or if you’re on an Iridium-linked vessel, the existing ways of accessing the data just don’t meet the need.”
He described his own experiences of working in Arctic coastal communities or being on board a retrofitted crabber, “We just struggled to get the data through the existing methods and we couldn’t get all the data we wanted.”
Today, Fischbach relies heavily on two satellites we’ll be following closely this summer — Aqua and Terra. Both are part of NASA’s Afternoon Constellation or A-Train, which is a convoy of satellites operated by NASA and international partners. The satellites travel together, completing a polar orbit twice a day; because of the Earth’s rotation, a polar orbit means that the satellites will observe the entirety of the planet’s surface every one to two days.
The A-Train crosses the equator at about 1:30 a.m and 1:30 p.m.; the Terra satellite passes the equator in the early morning, Aqua in the afternoon. This timing and repetition allows scientists to generate cloud-free images and to study how temperatures over land and water change from day to day.
By flying satellites loaded with a host of Earth-observing instruments in a formation, scientists are able to gather a great deal of meaningful data. According to NASA, flying in concert “allows for synergy between the missions—synergy means that more information about the condition of the Earth is obtained from the combined observations than would be possible from the sum of the observations taken independently.”
While each satellite is tasked with different mission objectives, the data from individual instruments can be combined to paint a more vivid and informative picture of the Earth’s climate and atmospheric systems.

A key instrument on board Aqua and Terra is a moderate resolution imaging spectroradiometer, or MODIS for short, which is capable of of observing across 36 spectral bands or wavelengths at different resolutions (250, 500, and 1000 meters). (A complete technical profile of this instrument and the data it provides can be found here.)
MODIS is an integral instrument for studying the ocean, because it aids in the creation of ocean color maps. Ocean color reveals much about phytoplankton productivity, which, according to NASA, forms the basis of the ocean’s food chain and plays a big part in carbon storage and movement. MODIS also allows for detailed maps of sea surface temperatures, which are known to influence weather patterns. Since MODIS is able to study water in liquid, solid or gas form, the instrument aids measurement of snow and sea ice and how much solar energy is being absorbed or reflected back to space.

Fischbach explains that the images in his daily emails (seen above) are processed with false color so you can distinguish the white of the clouds with the white of the sea ice; sea ice is aqua-colored and the clouds appear white. The images show detail down to 250 meter resolution, meaning you can clearly see objects that are 250 meters or 820 feet wide.
To people living and working in the the Arctic, these sea ice data could be comparable to monitoring hazards on roadways in the lower 48, because the ice and water provide access for both transportation and food.
The ice is moving constantly, which creates precarious decision-making choices in remote regions without the right information. With several days of ice data in hand, people in the field like Fishbach and Divoky can make better choices.
“I’d really like to know as much as I can about how the ice is moving. Is there more ice coming this way? Is it going to be congesting? Is it going to be opening up?” he asks. “You know, do I launch boat out in to the ice — the shifting seascape — where I could get pinned in and trapped and not make it home?”
