Berit, the storm that thrashed Scandinavia in late November, homogenised Byfjord’s surface layer. The temperuater decresed by about 3 degrees and the salinity decreased as freshwater from the surface was mixed into the water column. For the deepwater, storms such as these do not improve the oxygen concentrations as sea level within Byfjord is to [...]

Over the past month, the pumps have reduced the deep-water salinity after an inflow in October. The average salinity below sill depth is 27.5, which is a few tenths lower than in October. Oxygen concentrations are increasing in the upper part of the deep-water, but remain low at the pump outlet depth. However, hydrogen sulphide [...]

An inflow occurred in mid-October. The inflowing water was old deep-water from Havstensfjord. This water was lifted up and over the Sunningen sill due to ventilation of the upper deep-water in Havstensfjord. The inflowing water was warmer, saltier and poorer oxygenated than the water in the Byfjord basin. The temperature increased from 9 to 11 [...]

Colder air temperatures cool the Byfjord surface. Since August, the water temperature in the top most 10 metres has decreased by almost 5 degrees Celsius. Meanwhile, summer water has been mixed further down into the water column, showing as increasing temperatures at sill depth. The deep-water temperature is also increasing. Over the past month the [...]
