RDSEA has teamed up with Olin Hydrographic Solutions (Miami, FL) on an ocean survey at the mouth of the Waini River in western Guyana (just to the east of Venezuela). A full hydrographic survey is being conducted along with the offshore assessment of ocean currents, waves and water level at the mouth of the river. The end assessment and reporting will assist with the movement of vessel traffic in and out of the river for commerce.
Upwelling events have been observed along the central east Florida shelf since 1944. This region is oceanographically data poor. Acoustic Doppler current profilers (ADCP) deployed in 8~m depth offshore Sebastian Inlet State Park, Brevard County, Florida have recorded frequent summer cold water upwelling events. A 2003 upwelling event recorded at this site had a water temperature decrease of 15°C as compared to pre and post upwelling water temperatures. Profiled current velocities will be collected over a 3~mo deployment period during the 2011 and 2012 summer at the inner, mid and outer-shelf. The water velocities and water temperatures collected by the ADCPs will provide information on the path of the upwelled cold water masses onto the shelf and into the near-shore. ROMS, a 3-D primitive equation ocean model will be used to simulate near-shore cold water upwellings along the central east Florida shelf using forcing from larger oceanographic and meteorological models. The collected in situ ADCP data along with Gulf Stream transport values will be diagnostically compared to the ROMS simulations to confirm if an ocean model can accurately simulate upwelling in the nearshore.
