1) Three Virtual Director users
examine Chesapeake Bay.
2) West is
up, north to the right, as the animation begins.
Data from Glen Wheless and Cathy Lascara, Center for Coastal Physical Oceanography, Old Dominion University.
Of these data, Glen writes:
The isosurface shows the position of a
particular value of a tracer which simulates the position of a patch of
larval fish. The color represents the salinity at that location, red
being very saline and yellow being more fresh.
The simulation is a 15 day run, tides are
semi-diurnal, in other words, 2 highs, 2 lows per day. Winds originally
blow from SW to NE then reverse, simulating a low passage or northeaster.
You can see how the wind blows the 'fish' away then back to the mouth of
the bay where the tides then act to bring some of the fish into the Bay,
possibly serving as a mechanism for retention.
