Weddell Seal Science

Weddell Seal Science is a science outreach effort of the Erebus Bay Weddell Seal Population Study, one of the longest-running ecological population studies of a long-lived mammal. Since 1968, Weddell seals (Leptonychotes weddellii), the southernmost breeding mammal on the planet, have been observed, studied, and recorded on the icy bay of McMurdo Sound, Antarctica. In 2002, the population project moved to Montana State University, where it is managed today, extending the legacy of Antarctica Weddell seal population science.

The project investigates the seals’ population fluctuations year over year, documenting new pup births and overall population numbers. Researchers use simple technology to mark every new pup born in the study area, and advanced statistical analyses and models to better understand Weddell seal population dynamics and changes over time.

Weddell Seal Science also emphasizes public outreach and science education. Their website features videos, field blogs, interactive media, and a free multimedia eBook –Weddell Seals: Science, Life History, and Population Dynamics, available on Apple Books and Google Play. The project’s materials are curated by multimedia specialists Mary Lynn Price and Jeremy Schmidt, offering an engaging look into the lives of these southernmost mammals.
