Stable isotopic composition (d13C and d15N) of sinking particulate matter measured from short-term sediment traps in the northern Barents Sea during August 2019, Nansen Legacy cruise 2019706 Q3 ...
Samples for carbon and nitrogen isotopic composition of sinking organic matter were collected with short-term drifting sediment traps between 75° and 85°N in the northern Barents Sea with R/V Kronprins Haakon in August 2019 as part of the Nansen Legacy project (cruise 2019706, Q3). High-density bott...

| Summary: | Samples for carbon and nitrogen isotopic composition of sinking organic matter were collected with short-term drifting sediment traps between 75° and 85°N in the northern Barents Sea with R/V Kronprins Haakon in August 2019 as part of the Nansen Legacy project (cruise 2019706, Q3). 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 18 to 25 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. Between 250-1000ml were filtered onto pre-combusted 0.7µm GF/F filters (Whatman, combusted for 7h at 450°C) for the analysis of carbon and ... : 5 NetCDF Data Format data, totaling ...... 35.49 KB 5 ASCII text, with no line terminators, totaling ...... 160 B ... |
