CIRCULATION PATTERNS AT THE MOUTH OF NARRAGANSETT BAY FROM SHIPBOARD ADCP DATA
 
The flushing and exchange of water from Narragansett Bay are strongly modulated by circulation patterns at the interface between the Bay and the inner shelf of Rhode Island Sound (RIS). The spatial and temporal variability of these circulation patterns were measured during a series of shipboard ADCP and hydrographic surveys which extended across the mouth of Narragansett Bay and along a grid approximately 2 nm into RIS. Data were collected over complete tidal cycles on 7 days with similar tidal amplitudes (~1.2 m) between April and August 1998. Results show significant lateral differences in flow across the deeper East Passage entrance to the Bay, with less variability across the shallower West Passage. These lateral shears were greatest at the transition between flood and ebb. Vertical differences in flow were more pronounced in the adjacent regions of RIS where the flow magnitudes are only 50% those a the entrance to the Bay. These data represent one component of a multi-year, multi-disciplinary study of exchanges between Narragansett Bay and Rhode Island Sound.
