In winter 2007/2008, a low-pressure trough related to the Icelandic Low dominated the northern North Atlantic, the Nordic Seas and stretched deep into the Barents Sea (Figure 4.2.1). Large negative air pressure anomalies (-4 - -5 mb) were spread over the Norwegian and northern Barents Seas. The southern part of the Barents Sea were dominated by a bit smaller negative anomalies (-3 - -4 mb). Such an air pressure pattern would have strengthened the southwesterly winds and increased transport of warm air and water in the southern Barents Sea.Deprecated: Assigning the return value of new by reference is deprecated in /home/barentsp/public_html/barentsportal09/plugins/content/plugin_gmaps.php on line 173

Air temperature data were taken from http://nomad2.ncep.noaa.gov/ and averaged over the western (70-76°N, 15-35°E) and eastern (69-77ºN, 35-55ºE) parts of the sea. During winter and spring, the air temperature was warmer than normal, with maximum positive anomalies (6.0-7.0 °C) in the eastern Barents Sea in February and March. In April-September, the air temperature was generally close to the long-t...

Sea surface temperature (SST) data were taken from http://iridl.ldeo.columbia.edu/ and averaged over the Bear Island – Svalbard area (74-79ºN, 08-25ºE), central (71-74ºN, 20-40ºE) and southeastern Barents Sea (69-73ºN, 42-55ºE). The SST shows much of the same variations as the air temperatures. During winter, over most of the Barents Sea, SST was higher-than-normal, with maximum anomalies of 1.2-1.4...

The temperature and the volume flux of the inflowing Atlantic Water in the Fugløya-Bear Island Section do not always vary in phase. The temperature is mainly determined by variations upstream in the Norwegian Sea, while the volume flux to a large degree varies with the wind conditions in the western Barents Sea. The volume flux varies with periods of several years, and was significantly lower duri...

Throughout most of the year of 2008, the sea ice extent was less than normal, but more than in 2007. In comparison with the previous year, the ice coverage (expressed as a percentage of the sea area) was 2-6 % more in January-March and twice as much by June. In May, a polynya started to form south of the Franz Josef Land archipelago and in July the ice massif was finally broken. Come September, th...
