Elephant seals are helping map the Southern Ocean. This week on Oceanography, we’re sharing a special crossover episode from South Pole, another Pine Forest Media series focused on Antarctic science and research. In this episode, Dr. Clive McMahon explains how southern elephant seals are being equipped with ocean sensors to collect real-time data in one of the most remote and extreme environments on Earth. These deep-diving animals gather information on temperature, salinity, depth, and ocean productivity; especially during the Antarctic winter, when human access is nearly impossible. The conversation explores elephant seal behavior, population decline, Antarctic bottom water, and how animal-borne data is advancing oceanography, climate science, and weather forecasting. A fascinating look at how marine life is contributing directly to scientific discovery.
