Description
Summary:The south-western quarter of the North Sea (between the Wash and the River Tyne) has been investigated for the presence of dinoflagellates. Extensive net surveys were carried out in March, May and June 1971 and a number of other collections were made in the area. North of flamborough Head, the spring bloom of diatoms was succeeded by a considerable growth of dinoflagellates, of which Dinophysis norvegica was the most abundant organism. Maximum counts of > 28 million dinoflagellates per m Super(3) were recorded. Distribution charts are given for the most common spp. A total of 61 spp was found during the course of the survey.
