Creativity - Using Elephant seals to dive under Antarctica and get Data about why the ice shelf is melting!
Because the ability for humans to dive under the Antarctic ice shelf does not really exist, scientists have put small sensors on elephant seals to measure water temperature, depth, and salinity. With tens of thousands of dives and data sets, they have determined one reason why the ice shelf has been melting (from bottom up) so quickly - there is a warmer pocket of water that gets mixed into the colder water, raising the temperature above the melting point. This mixing is part of an underwater cyclone! Fascinating results from a truly creative way of collecting data. Check out the Washington Post article.
