Since the month of June 1991, we have been carrying out systematic samplings of the oceanographic, physical, chemical and plankton community parameters at three sampling stations located radially opposite Cabo Mayor on the coast of Santander. To date, monthly sampling has taken place, with the result of 14 uninterrupted monthly samples. The recording of temperature and salinity is obtained in the 0-100m column. Nutrients and the phytoplanktonic community are sampled at fixed depths of 0,5,10,40 and 60m. Zooplankton is sampled in the 0-50m column using 250 micron nets. Experiments on primary production (using method C14) are only carried out in the intermediate season (110m depth) during the months of June and September.
