This data set contains vertebrate data from 108 trawls. For each trawl, the entire catch was identified to species level. This dataset contains abundance, length, weight and disk width (if applicable) measurements. 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.

Seven research vessels have been used over the course of the time series with comparable gear i.e. an ~15m headline otter trawl with a small mesh cod-end or a cod end liner of mesh size 20mm. 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). Data of lower confidence levels, including invertebrate records and sex data for non-elasmobranchs, has been excluded from this data set but can be requested via 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. Record Types (see SpeciesNotes in taxon form) describe the measurements that were carried out for the sample and/or individuals: Individuals - (Each individual caught has been weighed, measured and counted), Abundance / Weight - (All individuals landed have been weighed and counted as a whole, not individually), Sub-sample (Abundance) - (Measured total weight off all landed individuals, and from this estimated total abundance) and Sub-sample (Weight) - (Counted the total abundance of all landed individuals and from this estimated the total weight). Please note that where an unknown weight occurred, the database auto-filled the blank entry with a value of 1. Therefore if weights are from a record types of 'Abundance/Weight' and 'Subsample Abundance' with values of 1, these are assumed to be an auto-filled value and have been changed to unknown within this data set. Where an 'Individual Weight' or a Wet weight biomass which is Record Type 'individuals' and abundance of 1, contain a value of 1, this is assumed to be correct and has not been changed in this data set, but should be treated as correct under the data user's discretion. If any sensitive species or biotope records are present within this dataset, they will have been removed. If you wish to request access to sensitive species records, please contact the metadata contact. The UK Sensitive Species list has been agreed by UK statutory bodies and relevant experts. It can be viewed here https://docs.nbnatlas.org/sensitive-species-list/. Please note sensitive species lists can vary across the UK.
