Abstract:
This dataset represents the sediment properties and physical environment of the seabed for the Greenland Sea and Barents Sea shelf area. The data were produced at a spatial resolution of 0.01 by 0.01 degrees. Available variables include: whole sediment mean grain size, mud, sand and gravel percentages, rock cover, porosity and permeability, carbon and nitrogen content of sediments, depth, slope, roughness, terrain ruggedness index, topographic position index. The dataset also includes a seasonal cycle of monthly natural disturbance and bed shear stress.
This dataset was produced by the MiMeMo project (NE/R012571/1), part of the Changing Arctic Ocean programme, jointly funded by the UKRI Natural Environment Research Council (NERC) and the German Federal Ministry of Education and Research (BMBF).

Abstract:
This data product comprises 5 files, containing marine sediment pore water and solid phase leachate silicon (Si) isotopic and element concentration data, as well as benthic silica flux magnitudes derived from core incubation experiments and sediment biogenic silica contents. Samples were collected over three cruises of the Changing Arctic Ocean Seafloor (ChAOS) project summer sampling campaigns in the Barents Sea between 2017 and 2019 aboard the RRS James Clark Ross (cruises JR16006, JR17007 and JR18006). The aim of this study was to improve our mechanistic understanding of the cycling of Si within the Arctic Ocean seafloor through measurement of stable Si isotopes in the dissolved Si pool and the solid phase sources.
This project was part of the Changing Arctic Ocean programme, funded by the Natural Environment Research Council (NERC) (grant no. NE/P005942/1).

Abstract:
Water column acoustic data collected in the Scotia Sea (from 2016-12-09 to 2017-01-15) during cruise JR16003.
Multi-frequency (38,120 and 200 kHz) acoustic data were collected using a Simrad EK60 echo sounder. The dataset comprises of calibrated and processed 38 kHz volume backscattering strength (Sv, dB re 1m-1). Data processing was undertaken using Echoview and Matlab. Processed netCDF data files are made available as part of the NERC Southern Ocean Network of Acoustics (SONA) and the EU MESOPP project.
