Abstract
The main objective of this project is to model the biological-physical mechanisms controlling the development of 3D spatial patterns of lower food web (NPZD) and dominant copepod species on Georges Bank/Gulf of Maine over time scales of days to years during the US GLOBEC period (1995-1999). This modeling effort is studying how local-dynamics and external physical forcing impact the abundance of the target species. The study is examining the relative importance of food-limitation, predation, and advection. The FVCOM is being used together with GLOBEC and other data sets, to conduct targeted numerical experiments examining such factors as sustainability of resident populations (in the absence of immigration), the effects of intrusions of Labrador water from the slope and Scotian Shelf, and scenarios of low-salinity intrusions and catastrophic global warming.
