This is an introductory course intended for undergraduate and graduate students with knowledge of basic ecology. The focus will be on OCEANOGRAPHY, with investigation on interactive biological, chemical, and physical processes in the ocean. The purposes are to give an overview of biological ocean science (a wide rather than deep view) and to provide basic information and training for graduate research. The discussion will range from physical effects on the biology to biological effects on biogeochemical cycling; the spatial scale will range from individual organisms (e.g. viscosity and turbulences on plankton feeding and nutrient uptake) to ecosystem (e.g. remote sensing and circulation modeling); the organism will range from virus to whales.
