Metadata: Predicted sedimentation rates data for the Baltic Sea derived from samples from 1992 - 2019
Abstract:
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.

| Title | The title is used to provide a brief and precise description of the dataset such as 'Date', 'Originating organisation/programme', 'Location' and 'Type of survey'. All acronyms and abbreviations should be reproduced in full. | Predicted sedimentation rates data for the Baltic Sea derived from samples from 1992 - 2019 |
| File Identifier | The File Identifier is a code, preferably a GUID, that is globally unique and remains with the same metadata record even if the record is edited or transferred between portals or tools. | CEFAS5f614dc5-be0c-4379-8dad-33dce560813b |
| Resource Identifier | This is the code assigned by the data owner. | CEFAS20933 |
| Resource type | The resource type will likely be a dataset but could also be a series (collection of datasets with a common specification) or a service. | dataset |
| Start date | This describes the date the resource starts. This may only be the year if month and day are not known | 1992-01-01 |
| End date | This describes the date the resource ends. This may only be the year if month and day are not known | 2019-03-31 |
| Spatial resolution | This describes the spatial resolution of the dataset or the spatial limitations of the service. | 95 |
| Spatial resolution unit | This describes the unit of spatial resolution which for distance must be metres. | urn:ogc:def:uom:EPSG::9001 |
| Frequency of updates | This describes the frequency with which the resource is modified or updated i.e. a monitoring programme that samples once per year has a frequency that is described as 'annually'. | notPlanned |

| Lineage | Lineage includes the background information, history of the sources of data, data quality statements and methods. | The spatial prediction of sediment accumulation rates were generated for the Baltic Sea using a machine learning approach. In short, a range of predictor variables that were thought to relate to either marine dispersal or the proximity to a sediment source. These full coverage predictor variables included: derivatives of the bathymetry, estimates of sediment turbidity, distance from river mouths, estimates of the energy of the Baltic Sea and a description of the substrate type. A random forest model was fit to the predictor variables using field observations. The model was then used to predict sediment accumulation rate for the Baltic Sea. |
