New preliminary data on VME encounters in NAFO Regulatory Area (Div. 3M) from EU-Spain and Portugal Groundfish Surveys (2020) and Canadian surveys
During the 13th NAFO Working Group on Ecosystem Science and Assessment (WGESA) virtual meeting new preliminary data on deep-water corals and sponges were presented from the 2020 EU-Spain and Portugal and Canadian bottom trawl groundfish surveys. The data was made available to the NAFO WGESA to impro...

Based on these thresholds deep-water coral and sponge data were identified and mapped, overlaid with the current closed areas, polygons for kernel density of sea pens and modified kernel density polygons for sponge grounds and large gorgonian VMEs. New thresholds and VME polygons were presented at the 12th WGESA meeting using additional data since 2013.
