| Summary: | Samples for fecal pellet 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 March 2021 as part of the Nansen Legacy project (cruise 2021703, Q1). 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 cylinders at each depth (30m and 120 or 200m) for a duration between 12 to 39 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. Upon retrieval, the content of the cylinders from each depth was pooled and stored at 4°C in dark until further analyses. For the microscopic examination of fecal pellets, a subsample of 250ml was transferred to a plastic bottle and fixed with hexamine-buffered 37% formaldehyde (final pH = 7) to a final concentration of 4%.
