The data has been collected during Nansen Legacy Joint Cruise 2-2 from 24 August - 29 September 2021 on the research vessel RV Kronprins Haakon (cruise number 2021710), along a transect in the northern Barents Sea from 76N to 82N. The dataset contains an abundance of pelagic marine protists, including phytoplankton (autotrophic) and protozooplankton (heterotrophic). Protists were identified and counted with light microscopy using the Utermöhl method and the result are given as cells per liter (cells/L)Sampling Description
Study Extent
The sampling covers a transect from North of Svlabard (81N)) to the central Arctic Ocean (88N)Sampling
The samples were collected with Niskin bottles attached to a CTD rosette at the following depths: 5, 10, 30, 60, 90 m, and deep chlorophyll max (DCM). The samples were preserved using an aldehyde mixture of glutaraldehyde and hexamethylenetetramine-buffered formalin at final concentrations of 0.1% and 1% respectively.Method steps
- All samples have been analyzed at the Institute of Oceanology of the Polish Academy of Sciences (IOPAN). The organisms were identified and counted under an inverted microscope according to the Utermöhl method.
