UK shelf and North Sea quantitative sediment composition predictions

Oliver Williams
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...

Biotope (macrofaunal assemblage) map and associated confidence layer based on grab and core data from 1976 to 2020

Two vector (.shp) files are provided. The first, (macro_assemblages.shp) shows the modelled (random forest) macrofaunal assemblage type based on a clustering of abundance data from the OneBenthic database (see https://sway.office.com/HM5VkWvBoZ86atYP?ref=Link). The second file, (macro_assemblages_confidence.shp) shows associated confidence in the modelled output, with darker shades (high values) indicating higher confidence and lighter shades (lower values) indicating lower confidence. Both layers can be viewed in the OneBenthic Layers tool (https://rconnect.cefas.co.uk/onebenthic_layers/), together with further details of the methodology...
