Ocean mixing process study

Nansen Legacy cruise number: 01

Cruise name: Ocean mixing process study

Cruise leaders: Ilker Fer (UiB) and Frank Nielsen (UNIS)

Duration: 27. June – 10. July 2018

Ship: R/V Kristine Bonnevie


Short description:

The cruise addressed objectives of work package ‘Physical drivers’ (RF1), focusing on ocean mixing and water transformation process studies in the region west and north of Svalbard, with particular focus on the warm Atlantic boundary current.

Ocean stratification, current and microstructure measurements were made. Four main sections were taken across the path of the warm West Spitsbergen Current; a fifth section was interrupted by the ice edge extending to shelf at 24E. Profiles were collected at stations along the sections from shelf to deep water as, well as at two repeated stations, each for approximately 24 hours duration. The cruise was completed with a section into Isfjorden. In total 120 CTD (conductivity temperature depth), 106 LADCP (lowered acoustic Doppler current profiler), 200 microstructure profiles and 11.5 days of shipboard acoustic Doppler current profiler data were collected.
