Abstract:
Sediment organic material content obtained from replicate 0.1m2 USNL (Unites States Naval Laboratory) box cores are determined by loss on ignition.
Samples were collected on cruises JR16006 and JR17007.
Funding was provided by 'The Changing Arctic Ocean Seafloor (ChAOS) - how changing sea ice conditions impact biological communities, biogeochemical processes and ecosystems' project (NE/N015894/1 and NE/P006426/1, 2017-2021), part of the NERC funded Changing Arctic Ocean programme.

| Lineage: | Data were collected from each of 5 stations in 2017 (B13-B17) and 6 stations in 2018 (B13-B17 and Xs) during two consecutive cruises (RRS James Clark Ross: JR16006, 30th June to 8th August, 2017; JR17007: 10th July to 5th August, 2018) following a transect along the 30ºE meridian. At each station, sediment samples were obtained from four replicate 0.1m2 USNL (Unites States Naval Laboratory) box cores and analysed for sediment organic material content (%) at the University of Cambridge following a standard protocol (provided). Sediment weighted to 3 decimal places. | |
