Title

1984 - 1984 Centre for Environment, Fisheries & Aquaculture Science (Cefas) Southern North Sea and English Channel Plankton Survey - RV Cirolana 01/84

Abstract

Analysis results from a survey carried out in January 1984 in the Southern Bight area of the North Sea and in the eastern English Channel. Species targetted were herring larvae and plaice eggs. Plankton samples were collected at planned sites. This data consists of the numbers of plaice eggs, along with associated positional data and volumes filtered.

Quality and validity

Lineage

81 sampling stations were completed using the Lowestoft 53cm plankton sampler with 20cm diameter conical nose cone. Cruise report unavailable, but track charts available via link to British Oceanographic Data Centre (BODC) website. Data storage: The raw data were stored in 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.
