Abstract
    In the years 1968-1969 a start was made to investigate the rate of primary production in the eastern part of the Southern North Sea. Primary production was measured by an adapted incubator C14-technique. Although the meaning of potential primary production is rather limited in determining the actual rate in situ it can at least be used in a relative way, showing the differences in productivity between certain parts of the area investigated. In this way it could be shown that there is a trend of increasing potential primary production towards the coast during August and May. This "landmass" effect indicates a shortage in nutrient supply, which is limiting the rate of primary production in most of the area. The spring bloom of phytoplankton in 1968 must have taken place during March and April. The weather conditions for plankton growth in these months, were excellent. This could be the reason that the potential primary production results of May 1968 were rather low. During November 1968 there was not an increase of potential primary production towards the coast, which is probably due to less favourable conditions in coastal water during this period of the year. The distribution pattern of potential primary production shows a dominant influence of the Rhine-Schelde estuary, which is illustrated by the results of February 1969.The pH of seawater in the area is greatly influenced by primary production. This resulted in exceptionally high pH data in August 1969.
