Lester McKee for Bruce Jaffe cont. Latest information is historic (most recent period with data is ~1950s to ~1980s) But does give a perspective on where erosion and deposition occurs in the Bay

Bay erosion and deposition is spatially complex During the latest survey period, Bay saw net erosion

New survey data on bathymetry and texture could be analyzed to provide

more up-to-date estimates of bathymetric change the basis for better modeling of sediment transport
