Scientific Purpose/Goals: High resolution sea floor mapping was conducted in Tampa Bay between 2001 and 2004 as part of the CMGP Tampa Bay Study. Data were collected throughout the entire bay including all small, peripheral embayments and channels. Before models could be accurately applied, updated sea floor elevation mapping data was needed for the entire bay. Baseline maps provide the physical context, background and baseline information for other project research, monitoring, and modeling activities. Sea floor elevation mapping provides critical information for development of circulation, hydrologic, sediment transport, water quality, and urbanization integrated modeling.
