Summary

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 used to produce them. .. _https://sway.office.com/hm5vkwvboz86atyp?ref=link: https://sway.office.com/HM5VkWvBoZ86atYP?ref=Link .. _https://rconnect.cefas.co.uk/onebenthic_layers/: https://rconnect.cefas.co.uk/onebenthic_layers/
