[13] According to Arctic researcher Jennifer Francis, «The Arctic warmth is the result of a combination of record - low sea - ice extent for this time of year, probably very thin ice, and plenty of warm / moist air from lower latitudes being driven northward by a very wavy jet stream.»

The Arctic Ocean's surface temperature and salinity vary seasonally as the ice cover melts and freezes; [4] its salinity is the lowest on average of the five major oceans, due to low evaporation, heavy fresh water inflow from rivers and streams, and limited connection and outflow to surrounding oceanic waters with higher salinities.
