Plankton analysis data from a single survey carried out between Sept-Oct 1987
by the Centre for Environment, Fisheries and Aquaculture Science in order to
investigate the distribution and abundance of yolk sac herring larvae on the
spawning grounds east of the Isle of Man. Plankton samples were collected at
each site on a planned survey grid. This data consists of the numbers of
herring larvae, along with associated positional data and volumes filtered.

Twenty hauls were made with the 53cm high speed tow net, fitted with a
Guildline CTD package.
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 in the database. The data tables (but not
queries) have now been extracted into comma separated variable files. Plankton
data are normally expressed as either number of organisms per m3 or per m2.
These are calculated from the volume of water filtered (derived using
regression co-efficients calculated for different flowmeters). Number per m3
is obtained by dividing the numbers per sample by the volume filtered, and
number per m2 of sea surface is obtained by multiplying the number per m3 by
the mean total or sampled depth during a deployment.
