Predictor variables and sedimentation rate samples used to predict sedimentation rates within the Baltic Sea from 1992 - 2017
Summary
Input data used to predict sedimentation rate for the Baltic Sea. Observation data includes: Sedimentation rate data derived from isotope 137Cs tracers and pseudo-samples of zero sedimentation rate randomly placed in areas of rocky habitat. Sixteen predictor variables were considered for use in the sedimentation rate model. These were: Bathymetric Position Index (at three neighbourhood sizes); the Standard Deviation of bathymetry (at three neighbourhood sizes); Distance from Rivers (three layers representing different river catchment sizes); Substrate class (developed at a 1:1,000,000 scale for the Baltic Sea, classified to Folk5 level); satellite derived estimate for Suspended Particulate Matter in the water column (a winter and summer layer); Orbital Velocity at the seabed (a winter and summer layer); and Current Speed (a winter and summer layer).

Lineage
Sedimentation rate observations were downloaded from the EMODnet-Geology data portal (https://emodnet-geology.eu). The 100 pseudo-samples, which were assigned a sedimentation rate of zero, were randomly positioned within the area classified as rock in the 1:250,000 scale EMODnet Geology Substrate map. Predictor variables were downloaded from various sources. Derivatives of bathymetry were generated from the EMODnet bathymetry layer ( `http://www.emodnetbathymetry.eu/`_). Current speed and orbital velocity of waves were calculated by Cefas staff. Suspended inorganic particulate matter layers were derived from data downloaded from Copernicus online portal ( `http://marine.copernicus.eu/`_). The size of river catchments were calculated from the Copernicus EU-Digital Elevation Model v1.1 (`https://land.copernicus.eu/imagery-in-situ/eu-dem/eu-dem-v1.1`_). From this the distance from river mouths were then calculated by Cefas staff. .. _`http://www.emodnetbathymetry.eu/`: http://www.emodnetbathymetry.eu/ .. _`http://marine.copernicus.eu/`: http://marine.copernicus.eu/ .. _`https://land.copernicus.eu/imagery-in-situ/eu-dem/eu-dem-v1.1`: https://land.copernicus.eu/imagery-in-situ/eu-dem/eu-dem-v1.1
