UK scientists have recruited a squad of seals from the coast of West Antarctica to help measure the effects of climate change. The seals were equipped with sensors that measured the temperature and salinity of the Amundsen Sea.
The data collected from more than 10,000 dives, over 150,000 square km, discovered that the deep water current, the Circumpolar Deep Water, is bigger, warmer and saltier in winter months than during summer. This suggests that there is likely to be more melting of ice sheets during winter.
