Chlorophyll a of Size-fractionated Summer Phytoplankton Blooms at a Coastal Station in Málaga Bay, Alboran Sea

The chlorophyll a content of four different size fractions (<2, 2-20, 20-45, 45-100 μm) of phytoplankton at a coastal station of Málaga Bay (South Spain) were studied throughout the summer and autumn of 1989. Pigment concentrations in the surface of sediments were also measured. Episodes of increased chlorophyll a concentration revealed the transitory existence of several blooms. The large increases in biomass consisted mostly of nanoplankton...
