    dct:description """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), salinity, 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).""" ;
