In the sound off Longyearbyen harbor, the RV Kristine Bonnevie lies anchored due to lack of space at the key. The arriving scientists are ferried over by a small work boat.
The ship's CTD rosette is the oceanographer's primary tool, providing data profiles as the instrument is lowered over the ship's side. High precision sensors measure conductivity (C), temperature (T) and pressure (depth, D), as well as dissolved oxygen, .... Centrally in the rosette are the Niskin bottles, which are used to take water samples at selected depths, used for calibrating sensors and for more detailed analysis. For this cruise, the package is topped with a pair of up- and downlooking lowered acoustic doppler current profilers (LADCPs), providing high accuracy current measurements over the whole depth.
