Sea water properties

The measurement of repeated profiles of selected sea water properties is an important part of the marine monitoring at Arctic Station. Depth specific measurements of sea water temperature, salinity, conductivity, density, oxygen content and fluorescence is performed using a CTD-probe. The measurements take place once a month at three fixed stations, where the deepest station extends to 300 meters of depth. Strong annual variations in sea ice coverage and break-up commonly delays the early season possibilities of deploying the CTD-probe from the research ship ”Porsild”. Under these circumstances, the CTD profiles are measured through holes in the sea ice close the outlet of Røde Elv offering early season measurements down to approximately 150 to 200 meters depth.
