Mean content (%) of organic matter (OM), Total organic carbon (TOC), Total Nitrogen (TN) and mean ratios of TOC/TN (mol:mol) over the 2 first cm of sediment (± SD) at the three stations in Kongsfjorden, Svalbard (Inner (A), Middle (B), Outer (C)) in 2012 (May, August, October), 2014 (August) and 2015 (January). Significant differences among stations (p<0.05) are indicated by asterisk (*).;Principal component analysis based on the sediment variables (C:N, Chla:phaeo and C-Chla: TOC ratios, biomass of TOC, Chla and Phaeo pigments), benthic fluxes (oxygen, ammonium (NH4+), nitrate+nitrite (NO3-+NO2-), phosphate (PO43-), silicate (Si(OH)4-), and bioturbation coefficients (biodiffusion, Db and bioadvection, r) along the Kongsfjord area between 2012 and 2015. Loadings of environmental and biological/biogeochemical variables are shown in the left panel, and station/dates are shown on the ordination plot in the right panel.;Data archive from bulk sediment variables that were used for the figures 2, 5, the tables 1, 2 and the supplementary figure 1. Sedimentary content (%) in organic matter (OM), total organic carbon (TOC), total Nitrogen (TN) and mean ratios of TOC:TN (mol:mol), biomass (mg m-2) of TOC, Chla, Phaeo, and mean ratios of chla:phaeo (d) and C-Chla:TOC (%) over the 2 first cm of sediment in each sampled core at the three stations in Kongsfjorden, Svalbard (Inner (A), Middle (B), Outer (C)) in 2012 (May, August, October), 2014 (August) and 2015 (January). (nd means no data).;Data archive from sediment cores incubations that were used for the figures 3, 5, the tables 1, 2 and the supplementary figure 2. Biodiffusion (Db in cm² y-1) and non-local (r in y-1) transports, oxygen and nutrients net fluxes (mmol m-² d-1) at the sediment-water interfaces in each sampled core at the three stations in Kongsfjorden, Svalbard (Inner (A), Middle (B), Outer (C)) between 2012 and 2015.
