Occurrence records from 2003 to 2020 collected in UK waters were combined with baseline data including records as far back as 1890.

These data were combined with baseline data including records as far back as 1890. Incomplete records (data rows where species name, year and/or longitude or latitude were missing) and duplicate records (data rows where species name, year and longitude and latitude combinations were not unique) were removed. Occurrence records were spatially joined to the 10km assessment grid, and coastal or transitional waters (according to the Water Framework Directive boundaries). Occurrence records within transitional waters and/or outside the 10km assessment grid were removed leaving only those records which fell within the UK Marine Strategy Assessment area. .. _`nbn atlas`: https://nbnatlas.org/ .. _`marine recorder`: https://jncc.gov.uk/our-work/marine-recorder/ MEDIN 3.1.1
