Predicted sedimentation rates data for the Baltic Sea derived from samples from 1992 - 2019 dataset https://portal.medin.org.uk/portal/start.php?tpc=009_CEFAS5f614dc5-be0c-4379-8dad-33dce560813b Spatial prediction of the sediment accumulation rate, provided as a .geotif file (as an average linear rate in cm yr-1 since 1986) for the Baltic Sea created using a machine learning approach. Predicted rates of sediment accumulation vary from 0.08-1.67 cm yr-1. Field measurements were acquired between 1992 and 2012 as compiled by EMODnet Geology. Predictor variables were derived from 2003 to 2018 from various sources including EMODnet Bathymetry, Copernicus and Cefas staff. Modelling subsequently occurred in 2019 by Cefas. Further detail on the data sources are provided in the associated manuscript.
