Salinity Maps for Florida Bay
A 1-foot sea-level rise since 1850 may have increased the depth
of Florida Bay, with an accompanying increase in water exchange
with the Atlantic Ocean and the Gulf of Mexico. However, recent
data indicate restricted rather than enhanced exchange with these
adjacent water bodies perhaps as a result of local rapid
sedimentation. Some portions of mudbanks are accreting at about
0.5 in/yr, much faster than sea level rise this century (average
about 0.1 in/yr). The relationship between salinity contours and
mudbanks illustrates the influence of bathymetry on
circulation. The USGS is integrating existing and planned
turbidity and sediment studies to develop a sediment budget and
to evaluate the effect of sea-level rise, storms, and
sedimentation on circulation and nutrient supply in the Bay.
