Physical Criteria

### Some Criteria for Selection of Physical Forces/Processes/Features that Impact Marine Populations

- Currently a significant factor within one or more regions, in terms of:

  ---Dispersing or aggregating target species or prey

  ---Impacting growth rates/life history of target species

- Would be impacted under hypothetical climate change scenarios in a way that could affect target species

- Exists in different regions, but varies in importance, timing, etc. (indicates covariance, potential climate change effects)-links to variability in biology between regions

- "Integrator" of system dynamics, variability that influences marine populations
