Metadata: English Channel and North Sea Plankton Survey - RV Cirolana 01/94
Abstract:
This survey was carried out in January 1994 in the Eastern English Channel and Southern North Sea to study the transport, feeding and condition of herring larvae. Plankton samples were collected at each site on the survey grid. This data consists of the numbers of herring larvae and other zooplankton, along with associated positional data and volumes filtered.
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. | English Channel and North Sea Plankton Survey - RV Cirolana 01/94 |
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. | CEFAS374d428d-cf4b-4c0e-98ec-e7c6e9a573fe |
Resource Identifier | This is the code assigned by the data owner. | CEFAS2561 |
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 | 1994-01-06 |
End date | This describes the date the resource ends. This may only be the year if month and day are not known | 1994-01-19 |
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 |
Abstract | The abstract provides a clear and brief statement of the content of the resource. | This survey was carried out in January 1994 in the Eastern English Channel and Southern North Sea to study the transport, feeding and condition of herring larvae. Plankton samples were collected at each site on the survey grid. This data consists of the numbers of herring larvae and other zooplankton, along with associated positional data and volumes filtered. |
Lineage | Lineage includes the background information, history of the sources of data, data quality statements and methods. | A fine mesh (35 micron) auxiliary net was fitted to the 76cm plankton sampler and was used to take 31 samples for analysis of potential food organisms for herring larvae - the sampler was later lost on 9th January so future samples were taken using the dual Longhurst-Hardy Plankton Recorder system (270/20 micron aperture mesh) A Focus Instruments Optical Plankton Counter was fitted on the Longhurst-Hardy Plankton Recorder body in place of the fine mesh sampling system for trials and was also fitted with the coarse mesh system for comparison for sampling in the herring larvae patches. 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) 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. |
