Abstract

This paper examines the temperature and salinity patterns and evolution in the surface layer of the Arctic Ocean in 2007-2009 and deals with the factors impacting the extreme changes both in temperature and salinity in 2007. The large areas of positive and negative anomalies in temperature and salinity have been formed over the Arctic Ocean with the apparant frontal barrier areea between Eurasian and American basins. The followed years (2008-2009) exhibit the reducing of thermohaline anomalies between the two basins assuming gradually rcovering to the initial state.
Considering the mean salinities within 5-50 m depth one can claim that the positive linear trend is evident both in Eurasian and American basinss since 1950 to 1993 while the intensive freshening was obsserved in American basin in 2007-2009. We intend that these changes in salinity can be assumed as the signature of non-stationary nature of all Arctic marine environments.
