1. Copepods in a warming climate: A pan-regional model of Arctic and Northwest Atlantic systems PIs: Davis, Ji, Beardsley, Chen Goal: To better understand the biological-physical mechanisms that determine how global warming affects populations of key marine zooplankton species in the Arctic - NW Atlantic regions.

2. Approach Merge NWA and AO physical models via a global model grid Extend lower food web model across pan-regional domain Generate present and future (e.g 2050) environmental conditions. Determine copepod species population growth potential Use an IBM to examine transport and behavior on distributions Develop a evolutionary IBM for a generic copepod to determine selection of optimal life history traits under existing and future (warm) conditions across the pan-regional domain.
