Metadata: English Channel and Southern North Sea Plankton Survey - RV Corystes 4z/2003
Abstract:
Two plankton surveys were carried out (RV Cirolana 2x/02: 29th April-12th May 2002 and RV Corystes 4z/03: 4th-9th May 2003) in the English Channel and southern North Sea to determine the distribution and abundance of crab (Cancer pagurus) larvae in relation to fishing ground and sea bed sediments over the sea area bounded by latitudes 48° 30'N and 53° 00'N and longitudes 9° 00'W and 2° 00'W. This data consists of the numbers and developmental stages of crab larvae, along with associated positional data and volumes filtered.

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. | English Channel and Southern North Sea Plankton Survey - RV Corystes 4z/2003 |
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. | CEFAS5480f0a5-07ba-4551-844d-2afe9cbe6931 |
Resource Identifier | This is the code assigned by the data owner. | CEFAS2586 |
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 | 2003-05-04 |
End date | This describes the date the resource ends. This may only be the year if month and day are not known | 2003-05-19 |
Spatial resolution | This describes the spatial resolution of the dataset or the spatial limitations of the service. | 1000 |
Spatial resolution unit | This describes the unit of spatial resolution which for distance must be metres. | urn:ogc:def:uom:EPSG::9001 |
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. | Samples were collecting using a 53 cm high speed towed net (‘tin tow’), fitted with 20 cm aperture nose cone, 270µm mesh end bag and the Guildline Conductivity Temperature Depth (CTD) monitoring system. Sampler deployment:The sampler was deployed in a double oblique tow from the surface to within 2 m of the seabed. Veering and hauling speeds were manually adjusted to ensure that each depth band was sampled equally. At shallow stations, multiple double oblique dives were necessary to enable a sufficient volume of water to be filtered. A minimum sampler deployment time of 15 minutes was aimed for. On recovery, the net was carefully washed down and the sample collected from the end bag. Each sample was then fixed using buffered formaldehyde solution and transported to the laboratory for sorting and identification.Data storage:The raw data were stored on an Access database. The various data files were stored on the database in a series of tables linked by having the content of certain fields in common. All routine calculations, calibration changes and conversions were carried out on the database. The data tables (but not queries etc) have now been extracted into text files. Plankton data are normally expressed as either number of organisms per m3 or per m2. The number per m3 is obtained by dividing the numbers per sample by the volume filtered, calculated from the sampler flowmeters. Number per m2 is obtained by multiplying the number per m3 by the mean sampled depth during a deployment. |
