Japanese Researchers Appoint Seals To Collect Global Warming Data

Japanese researchers are training seals to survey under the thick ice sheet in Antarctica. To study global warming impacts, the researchers equipped seals with high-tech head-mounted measuring devices to gather observation data like water temperatures and salt levels, in areas with extremely harsh weather conditions. Notably, the data showed that the seals have covered a distance of 633km and a depth of 700m so far.
