摘要

Tampa Bay is a shallow, 'Y'-shaped coastal embay-ment that is located along the center of the Florida Platform — an expansive accumulation of Cretaceous-Tertiary shallow-water carbonates and evaporites that were periodically exposed during glacio-eustatic sea level fluctuations. As a consequence, extensive karsti-fication likely had a controlling impact on the geologic evolution of Tampa Bay. Despite its large aerial size (～ 1000 km~2), Tampa Bay is relatively shallow (mean depth = 4 m) and its watershed (6700 km~2) is among the smallest in the Gulf of Mexico. About 85% of all freshwater inflow (mean = 63 m~3 s~(-1)) to the bay is carried by four principal tributaries (Orlando et al., 1993). Groundwater makes up an important component of baseflow of these coastal streams and may also be important in delivering nutrients and other constituents to the bay proper by submarine groundwater discharge.
