Downward vertical flux of protist cells and biomass in the northern Barents Sea during December 2019, Nansen Legacy cruise 2019711 Q4 ...
Samples for protist cell and biomass flux were collected with short-term drifting sediment traps between 75° and 85°N in the northern Barents Sea with R/V Kronprins Haakon in December 2019 as part of the Nansen Legacy project (cruise 2019711, Q4). High-density bottom water was collected at the stati...

| Summary: | Samples for protist cell and biomass flux were collected with short-term drifting sediment traps between 75° and 85°N in the northern Barents Sea with R/V Kronprins Haakon in December 2019 as part of the Nansen Legacy project (cruise 2019711, Q4). High-density bottom water was collected at the station and filtered (Whatman GF/F 0.7µm), and then filled into the trap cylinders (KC Denmark, aspect ratio >6) prior to their deployment. Afterwards, the sediment traps were deployed with 2 or 4 cylinders at each depth (30, 40, 60, 90, 120, 200m) for a duration between 28 to 42 hours. Depending on the sea ice conditions, the sediment traps were deployed in open water, anchored to a sea ice floe or within an ice lead. At one station, a sediment trap was deployed though a sea ice hole for 12 hours. Upon retrieval, the content of the cylinders from each depth was pooled and stored at 4°C in dark until further analyses. For protist examination, a subsample of 100ml was transferred to a brown glass bottle and fixed ... : 1 data, totaling ...... 14.72 KB ... |
