This survey was undertaken by Cefas as part of the CEFAS Historic surveys; Station and biological data collected during research surveys carried out by Cefas (formerly Directorate of Fisheries) in seas around the UK, mostly in the North Sea, since 1902. The survey hauls are not laid out systematically as a grid, as in current International Bottom Trawl Surveys (IBTS) and are widely distributed over (especially) southern and central North Sea areas. Gears and protocols were not standardised throughout, due to the long term nature of the series. Surveys took place in each season. Data are lacking for the periods of both World Wars. In some periods (e.g. the early 1900s), all species caught were recorded, whereas in other periods (e.g. 1920s-30s), only the key commercial species (e.g., Plaice, Sole and Cod) were recorded systematically. Note that some surveys targeted particular species (notably Plaice). Survey took place between 06/11/1953 and 11/11/1953 on Sir Lancelot Equipment used during this survey : - Otter trawl Codend catch Survey operations were undertaken on 21 stations 24 different species were caught on this survey

| Title | The title is used to provide a brief and precise description of the dataset such as 'Date', 'Originating organisation/programme', 'Location' and 'Type of survey'. All acronyms and abbreviations should be reproduced in full. | Survey : SLAN/17/1953 (part of CEFAS Historic surveys) |
| File Identifier | The File Identifier is a code, preferably a GUID, that is globally unique and remains with the same metadata record even if the record is edited or transferred between portals or tools. | CEFASdb6b286f-cfb8-40f3-8816-0ee0d0d834b9 |
| Resource Identifier | This is the code assigned by the data owner. | CEFAS10401 |
| Resource type | The resource type will likely be a dataset but could also be a series (collection of datasets with a common specification) or a service. | series |
| Start date | This describes the date the resource starts. This may only be the year if month and day are not known | 1953-11-06 |
| End date | This describes the date the resource ends. This may only be the year if month and day are not known | 1953-11-11 |
| Frequency of updates | This describes the frequency with which the resource is modified or updated i.e. a monitoring programme that samples once per year has a frequency that is described as 'annually'. | notPlanned |

| Lineage | Lineage includes the background information, history of the sources of data, data quality statements and methods. | Surveys range from 1902 until the 1970s. Over the decades, at least 11 different Research Vessels (RVs) carried out surveys using different gear deployments and catch sampling protocols over time. Early, steam-powered vessels towed the trawl at a speed of approximately 2 knots, whereas in current, diesel-powered vessels this is standardised at 4 knots. The data constitute a highly valuable information source, however, owing to the above, data analysis and interpretation requires caution. Species and Gear code lists are available via the additional information source field. |
