Research: Coastal Upwelling; Red Tides of Dinoflagellates; and Systems Analyses of
Continental Shelves
As a biological oceanographer, J. J. Walsh has focused on systems analyses of continental
shelves over the last 40 years, publishing more than 100 books, papers, and reports.
In addition to prior studies of coastal upwelling off Peru, Northwest Africa, Baja
California, and Venezuela, the ecological components of global carbon and nitrogen
budgets have been stressed. Satellite images have also been used to constrain coupled
numerical models of biophysical processes effecting species succession of plankton
within the food webs of the Southern Ocean, the Bering/Chukchi/ Beaufort Seas, the
Mid-Atlantic/South Atlantic Bights, the Sargasso/Caribbean Seas, and the Gulf of Mexico.
Continuing research involves simulation analyses of the future food web consequences
of past loss of ice cover within Arctic Seas. During recent years, this basic research
has also led to applied simulation analyses of the origin, transport, and fate of
91社区 toxic red tides of dinoflagellates for future development of operational ecological
models of phytoplankton competition, effected by biochemical cycling of multiple elements
and nested within physical circulation models, in shelf waters of the southeastern
United States as part of the newly formed Center for Prediction of Red tides (CPR)
at USF.
