Abstract The Plankton Dynamics During an Upwelling Cycle cruise was conducted from 14 to 28 February 1995 to study plankton processes following coastal upwelling off Cape Columbine and the Cape Peninsula. Mesoscale upwelled water masses were tracked using drogues, and routine sampling included CTD/rosette casts, nutrient uptake experiments and measurements of phytoplankton, microzooplankton and mesozooplankton. Transects perpendicular to the drogue track provided spatial perspective on bloom development and decline.
Methods Sampling during the cruise included CTD/rosette casts for hydrographic measurements and water sampling. Plankton community dynamics were assessed through measurements of phytoplankton, microzooplankton and mesozooplankton, along with nutrient uptake experiments. Drogues were deployed to track upwelled water masses, and repeated transects perpendicular to the drogue trajectory were conducted to observe spatial changes in bloom development and decline.
