This dataset has been extracted as part of an exercise to assemble "all" Cefas
Temperature Data and publish it in a Data paper. It is one of 17 Cefas data
sources assembled. Near surface temperature and salinity samples have been
collected by ferries, the most recent, the Stena Partner, along 52°N between
Harwich (formerly Felixstowe) and Rotterdam, from August 1970 onwards.
Throughout the year, at weekly intervals, temperature data were recorded and
water samples taken at 9 standard station positions across the Southern Bight
of the North Sea. These were sent back to Cefas to be analysed for salinity
and nutrients.
