Internal code | Internally assigned metadata identifier | 4196 |
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. | 1984 Bristol Channel benthic survey |
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. | 8dac07cb1b1a1270d9883e8d9e0c308e |
Resource Identifier | This is the code assigned by the data owner. | MRMLN001000000E5 |
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 | 1984-01-01 |
End date | This describes the date the resource ends. This may only be the year if month and day are not known | 1984-12-31 |
Spatial resolution | This describes the spatial resolution of the dataset or the spatial limitations of the service. | inapplicable |
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. | Modiolus modiolus presence records from a survey of the bottom fauna of the Bristol Channel and Severn Estuary. |
Lineage | Lineage includes the background information, history of the sources of data, data quality statements and methods. | The objectives of this survey were to gain a more fundamental understanding of the factors underlying the distribution, structure and functioning of benthic communities, and the interactions between benthos and other components of the ecostystem of the Bristol Channel. Samples of the bottom fauna have been taken on a grid of 155 stations in the Bristol Channel from Lundy Island to just above the Holme Island, using a Day grab and Naturalist's dredge. Stations were initially ordered into Petersen communities subjectively, on the basis of published descriptions of the species composition of these communities. This was followed by an objective computer classification, which facilitated the recognition of sub-groupings and gradations in species composition across comunities, which had previously escaped subjective identification. A map showing the area surveyed is given in the paper, however it was difficult to derive the exact locations from this map so a central point within the survey area has been used as the sampling location.This survey was collated by MarLIN as part of a data collation contract for species on the provisional list of Nationally Important Marine Features. |
