Phytoplankton distribution along the eastern coast of the USA. Part V. Seasonal density and cell volume patterns for the northeastern continental shelf
Department of Biological Sciences, Old Dominion University Norfolk, VA 23508, USA
Received on June 1, 1983; accepted on November 1, 1983 Seasonal phytoplankton distribution maps of diatoms, dinoflagellates and coccolithophores are given that identify major population centers over the northeastern continental shelf of the USA. Highest concentrations and cell volumes were associated with the large bay systems, the southern coastal section in the Gulf of Maine, Georges Bank, and sites along the shelf margin. The total shelf represented an extension seaward, to a lesser degree, of the coastal productive region. Although seasonal succession patterns occurred throughout the year, the major species that compose these sequences were seasonally ubiquitous, frequently producing localized and more abbreviated successional sequences over the outer shelf.
