Metadata: Nematode assemblages from trawling experiments at two stations in the southern North Sea, 1999-2000
Abstract:
Data is presented as counts of nematode worms present in samples obtained from two locations in the southern North Sea, the Western Mud Hole and the Botney Cut. These data are results of trawling experiments conducted from October 1999 to November 2000. Samples were collected from impact site A and an untrawled control site B at both locations. Data including the biomass and abiotic factors of the sampling locations are also available.
Data holder:
Centre for Environment, Fisheries and Aquaculture Science, Lowestoft Laboratory (CEFAS)

| 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. | Nematode assemblages from trawling experiments at two stations in the southern North Sea, 1999-2000 |
| 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. | CEFAS271cd60f-d1cd-4272-9953-74bf3c984ade |
| Resource Identifier | This is the code assigned by the data owner. | CEFAS20351 |
| 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. | dataset |
| Start date | This describes the date the resource starts. This may only be the year if month and day are not known | 1999-10-29 |
| End date | This describes the date the resource ends. This may only be the year if month and day are not known | 2000-11-29 |
| 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. | Trawling experiments were conducted at two sites in the southern North Sea, the Western Mud Hole and the Botney Cut, during an investigation of the short-term effects of beam trawling in the Southern North Sea. Trawling experiments were conducted at two locations in the southern North Sea: the Western Mud Hole (depth 39 m) and the Botney Cut (depth 59 m). The sediments at both experimental locations fall within the category of muddy sands (Western Mud Hole, mean particle diameter 76 lm) or muds (Botney Cut, mean particle diameter 16 lm). The sediment at the Western Hole consisted of 79% sand and 21% silt/clay; that at Botney Cut, of 27% sand and 73% silt/clay. Meiofauna were sampled randomly using a 0.1 m2 NIOZ corer at an impact site A and an untrawled control site B at both locations, once before and on several occasions after experimental trawling. After initial sampling, both impact sites (A) were trawled with a 4-m-beam trawl (25 parallel hauls). The trawl was fished at a speed of 5 knots (8 km h–1) and was fitted with 80-mm mesh and a chain matrix. The identification keys used were Platt & Warwick (1983, 1988), Warwick et al. (1998). |
