ON THE HYDROGRAPHY OF THE ST. ANDREW BAY SYSTEM, FLORIDA1

摘要: The St. Andrew Bay System consists of four coastal plain estuaries positive type. Temperature, salinity, and currents were observed over 24 hr for five to seven stations in the which occupied times different seasons. At two innermost stations, northern estuaries, influence drainage is strongest average salinity low. There almost no seasonal trend or stratification temperature salinity. Tidal bays are predominantly diurnal, corresponding tidal waves enter central bay through passes. Surface often indicated longer duration ebb than flood stage, owing effect drainage. Salinity change at surface bottom caused primarily by advective currents, while mid-depths, mainly due vertical motion halocline. some showed a continual decrease during hr, instead periodic persistent currents. Bottom however, usually changed periodically was constant, even these stations. In one survey, increase, winds. station narrow pass most sensitive An equation postulates that period proportional mean horizontal gradient current tested several examples. Vertical stability largest shows trend, as other open sea.
