Physical and chemical properties of seawater for the North Sea, in each month of 1976

Series of 12 cruises carried out by Cefas in 1976 on board RV Corella and RV
Clione, resampling a grid of fixed stations every month throughout 1976. Data
provided: date; station number; time; position (latitude and longitude);
depth; tide direction; wind speed and direction. Environmental variables
measured include: temperature (surface and bottom), saliny, transparency (%),
nutrient concentrations (nitrite, nitrate, phosphate, silicate); chlorophyll-a
(total and nano); phaeophytin (total and nano). These data have been converted
into digital format (excel files); however there is more data collected during
the same survey (e.g. fish stomach content; fish larvae counts; phytoplankton
counts) that has not been converted and is still in paper format (paper
records are kept by Steve Milligan, Plankton Lab).
