Abstract

When the mooring was deployed, surface waters were weakly stratified and there was little evidence of a phytoplankton bloom. Soon after the deployment, a marked increase in phytoplankton concentration occurred simultaneously with an increase of near-surface water temperature. The most striking observation was a period (year days 128-140) of strong mixed layer depth variability during which phytoplankton standing stock reached its maximum. The variability of the bio-optical parameters was extremely high, and deepwater phytoplankton concentration was much greater than would have been expected from the productivity estimates. Later, phytoplankton concentrations declined sharply in response to extremely stormy weather around year day 140. -from Authors
