Objectives:
To understand the biological-physical mechanisms controlling the development of 3D spatial patterns of lower food web (NPZD) and dominant copepod species on GB/GOM (days to years).
Examine local-dynamics and external forcing.
Determine the relative importance of food, predation, and advection.
Use FVCOM together with GLOBEC and other data sets, to conduct targeted numerical experiments: sustainability, SW and SS intrusions, catastrophic warming.

3. General Hypothesis
The seasonal evolution of characteristic spatial patterns of each dominant copepod species on GB/GOM is predictable from the interaction between its characteristic life-history traits and the biological and physical environment.
