Florida Bay Map and Guide


"Reflectance in Florida Bay is often correlated with depth, especially following strong wind events where bottom sediments in shallow regions are easily resuspended resulting in increased reflectance. Stronger reflectance is also typically found in regions that have lost seagrass coverage since sediments in these areas are easily mobilized. "
This NOAA/CoastView map provides adequate seatruth,
as the tide height is reported to be at most ~40 cm in Florida Bay.
