Elephant seals are helping to map the Southern Ocean. These extraordinary deep-diving animals are helping scientists study the Southern Ocean in places humans can barely reach, especially during the Antarctic winter. In this episode, Dr. Clive McMahon explains how southern elephant seals carry ocean sensors that collect real-time data on temperature, salinity, depth, and ocean productivity. The conversation explores elephant seal behavior, population decline, climate change, Antarctic bottom water, and the role these animals play in improving oceanography, weather forecasting, and climate science. If you’re interested in Antarctica, marine biology, elephant seals, Southern Ocean research, ocean data, or how animals can contribute to science, this episode offers a fascinating look at wildlife as scientific collaborators.
