Climate change in the ocean is causing both water temperature and sea level to rise. This means that many species of marine organisms are going to be experiencing drastic ecosystem shifts in the near future. A group of Canadian and American scientists have analyzed what these shifts could mean for large marine predators by combining tracking data from tagged predators with surface chlorophyll and temperature measurements taken by satellites. These data sets made it possible to model dynamic ocean habitats for large ocean predators for the first time.
