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 December 2019 as part of the Nansen Legacy project (cruise 2019711, Q4). High-density bottom water was collected at the station and filte...

| 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 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. 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%. A subsample of 25-100ml was settled in Utermoehl sedimentation chambers for a duration of 24h. Subsequently, the fecal pellets were enumerated, with measurements taken for the length and width of each individual pellet using a Leica inverted ... : 1 data, totaling ...... 11.15 KB ... |
