The cruise HM 2015617 onboard the Research Vessel Håkon Mosby is the second and last research cruise of the project ”On Thin Ice (NICE): Role of Ocean Heat Flux in Sea Ice Melt”. NICE is led at the Geophysical Institute, University of Bergen (PI: Ilker Fer) and is funded by the Research Council of Norway (project number 229786) for the period 01.01.2014-31.12.2017

Samples collected from an underway Towfish during RV Sanna cruise GLICE (August 2022) and either analysed at sea or returned preserved to GEOMAR for analysis. Sensor data refers to in-line data matching the underway samples.

Basic biogeochemical parameters obtained from the GLICE cruise in Disko Bay (August 2022), either analyzed at sea or preserved and returned to GEOMAR for analysis.

In September 2009, a ship-based study was carried out in the Davis Strait/southern Baffin Bay along a range of transects covering the area between the west coast of Greenland and Baffin Island (Canada) from 68-72º N . Water temperature, salinity and in situ chlorophyll a (chl. a) measured in 0-500 m depths followed the general hydrographical characteristics of the late summer situation. Surface chl. a concentration based on remote sensing satellite data from September 2009 supported these findings. Measurement of in situ chl. a concentrations revealed a maximum in the subsurface (30-50 m water depths). Thus, spatial distribution of the phytoplankton bloom was often restricted to subsurface rather than the surface waters and therefore not detected by the remote sensing during September.
