Scientists have attached sensors to seals’ heads to monitor the Antarctic Ocean.
Scientists have attached sensors to the heads of seals to monitor the ocean. Because seals are there all year round, and in places people can’t get to, they can collect data that we can’t. Researchers now know a warm underwater current varies during the year, which helps them understand the melting of Antarctic ice.
In nine months the seals recorded more than 10,000 measurements over an area larger than England.
Scientists believe this new data could make more accurate predictions about sea levels.
