Comparison dataset of Animalia in the North Sea, the English Channel and the Celtic Sea. Samples were obtained by MAFF research vessels from 69 stations between 1992-1996. A 2-m Lowestoft beam trawl with a 3 mm cod-end liner was deployed for 5–10 min across each station at a speed of about 0.5 m/s. Data includes information of the species found at each station. The start and end of the haul positions were recorded. Tow length averaged about 400 m, but varied substantially (s.d.=290) depending on tidal current velocity and wind strength at the time of sampling. On retrieval of the trawl, an estimate of sample volume was made, along with a summary of the contents, noting especially the presence of stones, rock, etc. The sample was then sorted on deck over a 5 mm mesh sieve.

| Abstract | The abstract provides a clear and brief statement of the content of the resource. | Comparison dataset of Animalia in the North Sea, the English Channel and the Celtic Sea.

| Lineage | Lineage includes the background information, history of the sources of data, data quality statements and methods. | Most specimens were identified and enumerated at sea. Any problematic specimens were preserved in formalin for identification on land. The presence of infaunal organisms arising from the fouling of soft sediments, and pelagic species such as jellyfish were noted. However, these records were excluded from the final compilation of the data. Motile taxa not dealt with at sea were identified to species level, as far as possible, using a range of standard taxonomic keys. Nomenclature followed that of Howson (1987). A ranked descriptor of the predominant substratum type along trawl tows was derived from a combination of records of trawl contents, particle size analyses of sediments from grabs where available, and information from Admiralty Charts. |
