The Plumb Line

(n.) A line used to determine depth; a sounding line. These special projects are at the heart of what we do. In each special Plumb Line series, you’ll find short explainers, in-depth profiles, podcasts, infographics, videos, photo essays, and anything else to help us in telling the story of science over time.


Arctic Change

George Divoky didn’t set out to study climate change, but climate change found him and his Arctic seabirds. This series follows his 44th field season studying Black Guillemots on Cooper Island, 20 miles east of Utqiaġvik, Alaska — exploring life on the front lines of change.

Sea Sentries

National Marine Sanctuaries include over 600,000 square miles of underwater parks in U.S. coastal waters and Great Lakes; these sanctuaries have been set aside to monitor ocean health and preserve precious biological and cultural resources. In July, Jenny Woodman will sail with a team of scientists on the NOAA Ship Bell M. Shimada in three sanctuaries off the coast of California, sharing live field reports, photo essays, and articles along the way.

Exploring Ocean Worlds

Every day, a small number of scientific explorers uncover remarkable underwater ecosystems that change our understanding of biodiversity in places we once thought void of life. Learn about ocean exploration and the people working to better know our planet.
