Metadata: UK shelf and North Sea quantitative sediment composition predictions
Abstract:
Spatial predictions of substrate composition for the UK shelf and North Sea. Compositional fractions of mud, sand and gravel were modelled for an area of the UK and North Sea using a statistical regression model. This dataset consists of percentage composition predictions for the mud, sand and gravel components as raster tifs. In addition the proportion of each of these sediment components were combined to predict the likely sediment classification as both a EUNIS habitat class and Folk class. These are also available as raster tif files with an associated ArcGIS layer file indicating the appropriate class for each raster value. A shape file of the Folk classification is also available.

| 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. | UK shelf and North Sea quantitative sediment composition predictions |
| 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. | CEFAS742b396b-e638-4501-8d43-9818510d13fd |
| Resource Identifier | This is the code assigned by the data owner. | CEFAS3313 |
| 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 | 2015-04-01 |
| End date | This describes the date the resource ends. This may only be the year if month and day are not known | 2015-04-01 |
| Spatial resolution | This describes the spatial resolution of the dataset or the spatial limitations of the service. | 500 |
| 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. | For a full description of the methodology used to generate these data see: `http://journals.plos.org/plosone/article?id=10.1371/journal.pone.0142502`_ In short, the analysis combined outputs from hydrodynamic models as well as optical remote sensing data from satellite platforms and bathymetric variables, which were mainly derived from acoustic remote sensing. A statistical regression model was built to make quantitative predictions of sediment composition (fractions of mud, sand and gravel) using the random forest algorithm. The compositional data was analysed on the additive log-ratio scale and then transformed back into percentages of the individual sediment components. From these percentage components a EUNIS substrate model was also generated. .. _`http://journals.plos.org/plosone/article?id=10.1371/journal.pone.0142502`: http://journals.plos.org/plosone/article?id=10.1371/journal.pone.0142502 |
