Scientists and Seals Investigate the Mysterious Southern Ocean

Researchers have gathered together a large volume of data from some of the world's harshest waters using seals.
The data these mammals have gathered could shed light on parts of the ocean that until now have been shadowed to scientists.
The group of seals have been equipped with special sensors.
They are allowed to wander as they normally would, having so far produced nearly 400,000 environmental profiles of the Southern Ocean as they go.
The result is a mammoth oceanographic database that's just been released via an online portal entitled Marine Mammals Exploring The Oceans Pole To Pole.
