The application of biochemical tests to implicate specific limiting factors has shown that for most of the growing season (spring through fall), nitrogen limits phytoplankton growth and more specifically controls the size of the blooms of phytoplankton in New England coastal waters. The seasonal sequence of phytoplankton appears to be a composite of two major blooms and numerous smaller outbursts of growth. The latter seem to be related to vertical turbulance which re-enriches the euphotic zone with nutrients. The cause or source of this turbulance is not clearly identified.
