Quality and validity

Lineage

The inshore haul has been undertaken using seven research vessels over the time series, each using 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. Gear descriptions for the time period 2004 - present are comprehensive. Gear specifications from historical data are less well described. There is high confidence in any dataset available for public download within this data series. There is high confidence in vertebrate species identification throughout the time series in the majority of species. Since 2004 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). There are less records of quality control procedures and gear specifications for historic data. These data are available through request to MBASepia@mba.ac.uk where specialist advice on data confidence and methodology can be provided in addition to the dataset. 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). Species recorded and confidence in identification within this dataset can be discussed via a data request.
