Each bullet point below describes the column in the datasheet - `station` - the station ID at which the sample was collected - `sea` - the sea in which the sample was collected - `latitude` - the station latitude (in decimal degrees) - `longitude` - the station longitude (in decimal degrees) - `depth_m` - the depth to the seafloor where the sediment core was collected (metre) - `temp_c` - the temperature of bottom water when the core was collected (°C) - `salinity` - the salinity of bottom water when the core was collected - `sio2_flux` - the dissolved silicon flux between the sediment and water coulm (μmol m⁻² d⁻¹) - `o2_flux` - the dissolved oxygen flux between the sediment and water coulm (μmol m⁻² d⁻¹) - `start_sio2_conc` - the dissolved silicon concentration in water overlying sediments at the beginning of the incubation (μmol L⁻¹) - `start_o2_conc` - the dissolved oxygen concentration in water overlying sediments at the beginning of the incubation (μmol L⁻¹) - `toc_perc` - the percent mass of surface sediment made up of organic carbon - `delta_13_c` - the δ13C of surface sediments (‰) - `asi_perc_mass` - the percent mass of surface sediments made up of amorphous silicon - `dist_from_river_km` - the distance (km) from the location the core was collected to the nearby river `water_column_si`: data from water column profiles measured along transects radiating from river outflows - `st` - the station id - `lon` - the station longitude (in decimal degrees) - `lat` - the station latitude (in decimal degrees) - `date` - the date the sample was collected - `bottom_depth_m` - the depth from the surface at the sampling site (metre) - `sea` - the sea in which the sample was collected - `bottle_num` - the smple bottle ID - `sample_depth_m` - the depth at which the sample was collected (metre) - `temp_c` - the water temperature (°C) - `salinity` - the salinity - `o2_conc` - the dissolved oxygen concentration (μmol L⁻¹) - `sio2_conc` - the dissolved silicon concentration (μmol L⁻¹) ##### Alternative contact person Birgit Wild ###### Email address [birgit.wild@aces.su.se](mailto:birgit.wild@aces.su.se) ###### Postal address Birgit Wild Department of Environmental Science Stockholm University SE-106 91 Stockholm Sweden
