The SAHFOS CPR survey is the longest and most geographically extensive marine biological survey in the world. The CPR survey has been in operation in the North Sea and North Atlantic since 1946 and has systematically sampled up to 500 planktonic taxa from the major regions of the North Atlantic at a monthly resolution. This dataset contains also CPR surveys in the Pacific and the South Atlantic.
