INTERANNUAL VARIABILITIES OF PHYSICAL PARAMETERS IN THE HORNSUND FJORD
Marine
Arctic Frontiers 2011, Tromsø, Norway
2011
The interannual variabilities of hydrological parameters in Hornsund Fjord (southwest coast of the Spitsbergen) has been observed during last decade. Data on physical parameters (tempearture, salinity, density) were collected every summer during Arctic experiments performed by Polish Academy of Sciences. For the last 2 years data were collected under ALKEKONGE project.
Hornsund Fjord is the most southerly, Arctic influenced fjord. Its cold conditions are consequence of the inflow of the Arctic waters from the Sørkapp Current flowing from the Barents Sea as well as by connection with numerous glaciers. There is also observed significant effect of sea ice production and melting and local atmospheric conditions. The investigation was focused on the inner fjord basin Breepolen, which constitute a reservoir of Winter Cooled Water.
The most warm event was observed in 2006, when the increase of the temperature and salinity was indicated. The maximum extremes can be indirectly related with the maximal values of hydrological parameters observed in the West Spitsbergen Current, and in particular on the continental slope. There are two pronounced patterns. In 2002 when the decrease of the temperature is accompanied by the increase of the salinity. The same situation appears apart eight years, in 2010.
