Abstract
    Parallel measurements were made of particulate and dissolved products of primary production, utilization rate of amino acids, monosaccharides, and glycollate, thymidine incorporation into DNA, and exoproteolytic activity before and during the spring bloom. A close coupling between microheterotrophic activity and primary production was demonstrated. Microheterotrophic activity could play an important role in food-web dynamics by partly satisfying the N needs of phytoplankton, which represents about twice the mineral N stock initially present in the water column.
