Elephant seals collect data where ships rarely can. In this South Pole crossover, Dr. Clive McMahon explains how animal-borne sensors turn deep-diving southern elephant seals into partners in Southern Ocean monitoring. The tags collect temperature, salinity, depth, and ocean productivity data, especially during the Antarctic winter. The episode also explores seal behavior, population decline, Antarctic Bottom Water, climate monitoring, and how hard-to-reach observations improve oceanography and weather forecasting
