This data set contains vertebrate data from 269 trawls. For each trawl, the entire catch was identified to species level. This dataset contains abundance, length, weight and disk width (if applicable) measurements as well as Catch Per Unit Effort calculations. This dataset contains consistent sex data for elasmobranchs. Invertebrate abundance data was also collected on each survey and is available on request to MBASepia@mba.ac.uk. These data include high confidence cephalopod, scallop and large crab abundance as well as counts of other invertebrates including other crustaceans and echinoderms. Environmental data (surface and bottom water temperature and salinity) was consistently recorded from 2020. Sensitive species as published by the National Biodiversity Network Trust (available: https://docs.nbnatlas.org/sensitive-species-list/ correct as of 03/02/2021) have been removed from the dataset but can be made available on request.

Seven research vessels have been used over the course of the time series with comparable gear i.e. an ~15m headline small otter trawl with a small mesh cod-end or a cod end cover of mesh size 5mm. There is high confidence in this dataset. Data is subject to quality checking of 10% of digitised data against paper records. Since 2018, taxonomic identification has been validated through the NMBAQC scheme. If there is any question of confidence of taxonomic identification of a species then a more general taxonomic level is used to describe these specimens (typically genus). Invertebrate abundance data is available through request to MBASepia@mba.ac.uk. There is high confidence in species identification of some species (e.g. cephalopods). This dataset can be made available via a data request to MBASepia@mba.ac.uk where specialist advice on data confidence and methodology can be provided in addition to the dataset.
