They called this project ICESCAPE (Impacts of Climate on EcoSystems and Chemistry of the Arctic Pacific Environment) which went to parts of northern and western Alaska and they were suprized on what they have discovered.
They found out that beneath the thick layer of ice in the area trives a special kind of species called a phytoplankton which is one of the evolutionary origins of marine life.
The shift the climate has caused the thinning of the ice which leads to the bloom of these creatures. This would also affect the ecosystem as polar animals depend on marine life.
