Auad, G. and A. J. Miller, 2008:
The role of tidal forcing in the
Gulf of Alaska's circulation.

High resolution (7 km) numerical simulations of the Gulf of Alaska circulation
show an indirect effect induced by tidal forcing. Tides stir the water column more
vigorously in the coastal ocean than in the Gulf's interior, leading to denser waters there
than offshore. This horizontal gradient induces a geostrophic current that, in general and
in most regions, flows against the mean general circulation.
