| Summary: | Samples for sinking mass flux of particulate organic carbon (POC) and nitrogen (PON) were collected with short-term drifting sediment traps between 75° and 85°N in the northern Barents Sea with R/V Kronprins Haakon in May 2021 as part of the Nansen Legacy project (cruise 2021704, Q2). 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 12 to 27 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 selected stations, single trap cylinders were deployed by divers 1m below the sea ice. Upon retrieval, the content of the cylinders from each depth was pooled and stored at 4°C in dark until further analyses. Between 250-1000ml were filtered onto pre-combusted ... : 6 NetCDF Data Format data, totaling ...... 37.68 KB 6 ASCII text, with no line terminators, totaling ...... 192 B ... |
