NOTE: This is a simulcast event from University of Georgia's Skidaway Institute of Oceanography in Savannah, GA ABSTRACT: A new profiling platform, the Coastal Bottom Drifter, was designed and built to observe near bottom environments in coastal regions. It is capable of drifting near the bottom with a prescribed clearance or at a constant depth and observe properties at up to 300 m of depth. The platform can be deployed for days or up to…

Estuaries provide critical habitat for eelgrass, oysters, and other species, and also serve as natural sediment traps. The sediment regimes of many modern estuaries are evolving, however, in response to land use changes, shoreline alterations, dredging, and other human impacts. In order to assess hydrodynamics and sediment dynamics in the Coos Bay Estuary (Oregon), we used an unstructured finite-volume model (FVCOM) and multi-year measurements…

ABSTRACT: Sediment transport processes affect oxygen and carbon dynamics in coastal environments through a variety of processes.  Seabed resuspension, for example, can vertically mix sediment and water, facilitating decomposition of organic matter and oxygen consumption. Redistribution of inorganic and organic particles among coastal environments, e.g. between marshes and estuaries, can also affect biogeochemical budgets. The relative importance…

Processes that either promote growth or cause mortality drive the abundance of all organisms. For microbes that have a lifespan measured in hours to days, small changes in growth and mortality rates can have significant impacts on their population dynamics. While factors that influence phytoplankton growth are often examined, it has been difficult to parameterize phytoplankton population dynamics due to incomplete estimates of phytoplankton…

Savannah, Ga. – Tiny pieces of plastic are so pervasive in Georgia’s coastal waters, researchers estimate there are more than a trillion microplastic particles and fibers in the top foot of the state’s inshore waterways.  The issue of microplastics in coastal waters and what, if anything, can be done about them will be the focus of a special Evening @ Skidaway program on Thursday, Nov. 16, in the McGowan Library on the University of Georgia…
