Abstract
In October 1988 a bloom of Gyrodinium cf. aureolum was recorded along a transect across the continental shelf reaching cell densities of 1300 ml−1 and chlorophyll a concentrations up to 16 μg 1−1. The bloom was restricted to a nutrient-rich thin surface layer of ∼10 m depth at the beginning of seasonal pycnocline. Hydrological conditions showed a particular salinity distribution. The phytoplankton community was dominated by G. cf. aureolum but the coexisting flora presented a great diversity. UV-absorbing pigments were recorded in the community.Keywords
