Service Description: Total abundanceof the sea squirt Ascidiella spp. from 1998 to 2014. Sea squirts or ascidians are sessile, sac-like invertebrate filter-feeders.
Samples were taken with a 2-m beam trawl from 1998 to 2014andcatches were sieved over 5-mm mesh size. 365 stations were sampled (usually24 per year, which were randomly distributed within 24 statistical rectangles of the International Council for the Exploration of the Sea (ICES)). Sampling did not take place in 2001 and 2002.Abundance data were standardized to a tow length of 250m.
