Metadata: Benthic macrofaunal abundance data from the Western North Sea collected from 2000 to 2002
Abstract:
Data contains the abundance of macrofauna in benthic samples obtained from 0.1m2 Hamon or Day grab samples conducted by Cefas in the Western North Sea between 2000-2002. Sampling occurred mainly in spring and early summer of 2000 in the North Sea. Sampling was conducted with a 0.1m2 Day or Hamon grab depending on the sediment type. Macrofauna were identified to species level and enumerated, with macrobenthos density derived.

Centre for Environment, Fisheries and Aquaculture Science, Lowestoft Laboratory (CEFAS)

| Internal code | Internally assigned metadata identifier | 10103 |
| 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. | Benthic macrofaunal abundance data from the Western North Sea collected from 2000 to 2002 |
| 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. | CEFAS84210ac6-2209-4616-9c66-86d7cd9843bd |
| Resource Identifier | This is the code assigned by the data owner. | CEFAS20700 |
| 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 | 2000-05-30 |
| End date | This describes the date the resource ends. This may only be the year if month and day are not known | 2002-05-30 |
| 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 |
| Abstract | The abstract provides a clear and brief statement of the content of the resource. | Data contains the abundance of macrofauna in benthic samples obtained from 0.1m2 Hamon or Day grab samples conducted by Cefas in the Western North Sea between 2000-2002.

| Lineage | Lineage includes the background information, history of the sources of data, data quality statements and methods. | The macrofauna was identified to species level, as far as possible, with the use of a range of standard taxonomic keys. All animals were enumerated, except for colonial organisms which were recorded on a presence/absence basis. The biomass of each taxon was determined as wet blotted weight, and then expressed as ash-free dry weight using conversion factors mainly from Rumohr et al. (1987). Samples for sediment composition and contaminants were taken, either from extra grabs or from the same grab as used for faunal analysis. Samples for analysis of meiofauna were also collected. Data was then used in the Defra ME3112 project, where environmental variables quantified for each station included bathymetry (except North Sea and western Scotland), stratification, bottom temperature and a number of derived granulometric parameters (e.g., % silt, % gravel, sorting coefficient, skewness, kurtosis), together with modelled parameters such as bed tidal stress, wave stress, bottom temperature, a stratification index and satellite-derived surface chlorophyll a (mean values for 2002-07 used). The main objective of the AE1143 project was to provide a strategic evaluation of the status of the benthic communities of the western North Sea, in relation to natural and anthropogenic influences. Sampling of the benthic macrofauna and sediments were collected from 89 total stations in the Western North Sea. While Cefas conducted several Hamon grab samples, other sation samples were provided by FRS, Aberdeen and the Senckenberg Institue, Germany. The English east coast, was sampled by CEFAS from the RV Cefas Endeavour using a variety of methods deemed compatible with the sedimentary habitat being targeted. Sediment sub-samples collected by CEFAS and FRS were analysed for particle size. Additionally, sub-samples at CEFAS stations were analysed for % organic carbon and nitrogen content and the concentrations of a range of trace metals. The ME3112 Project, which made use of this data, assessed the spatial distribution of the macrofaunal assemblages currently around the coast of England, Wales and the west coast of Scotland, together with an assessment of the factors affecting such assemblages. The project was intended to help underpin the State of the Seas report and to help manage the anthropogenic changes in the marine environment. This was part of a large scale sampling programme around the UK, spanning 2000-2009. |
