Long-term diving records of an adult female northern elephant seal
Seventy-three days long diving record of an adult female northern elephant seal (Mirounga angustirostris) was obtained using the long-term time depth recorder which was developed for Antarctic seal research by the National Institute of Polar Research, Tokyo. It was observed that the female northern...
