Abstract
This communication deals with some of the results of a taxonomic analysis of phytoplankton samples taken during the cruise Atlor II of the R/V Cornide de Saavedra, in March 19 73. These samples were collected every 30 min along transects between stations, from 3 m depth water which was continuously pumped into the laboratories. At an average speed of 8 knots, this represents a distance of about 7.2 km between sampling points. Simultaneously, samples for photosynthetic pigment determination were taken and particle counting with a Coulter Counter was also done; information concerning these parameters has been given by Estrada (1974) and Margalef (1974). A partial report of the analysis of phytoplankton data from the oceanographic stations has already been published (Margalef, 1975). Along many of the transects, temperature, fluorescence and concentration of nitrate and nitrite were continuously monitored and recorded by the minute by means of a data logger. Figure 1 shows the position of the stations and the traject of the ship.
