The movements of circumpolar Arctic gadids are dependent on complex dynamics that include regional currents, the longevity of ice-flows and polynyas, water stratification and coastal hydrology. Dependence on these interactive and often co-dependent processes highlights major pathways and barriers to movement and distribution at higher latitudes.
