Sedimentary Data from the Coastal Marshes Fringing the Lower Waccasassa River, Northwest Florida Sedimentary Data from the Coastal Marshes Fringing the Lower Waccasassa River, Northwest Florida
The Waccasassa River is located in a small watershed situated along the middle section of the low-gradient, low-energy, sediment-starved Big Bend coast in west central Florida. The river mouth empties into the head of the shallow, microtidal Waccasassa Bay and the Gulf of Mexico. The lower end of the river and the surrounding coastline are dominated by coast-parallel Juncus roemerianus...
Seasonal Sedimentary Data Collected from Old Tampa Bay, Florida, 2015-2016 Seasonal Sedimentary Data Collected from Old Tampa Bay, Florida, 2015-2016
The toxic dinoflagellate Pyrodinium bahamense produces recurring, persistent summer algal blooms in Old Tampa Bay, Florida, which degrade water quality and are potentially harmful to humans if contaminated shellfish is consumed. As part of its life cycle, Pyrodinium bahamense produces dormant cysts, which settle to the seafloor, forming seed beds that may initiate future blooms if...

How could a freshwater swamp produce a chemical signature characteristic of a saltmarsh? How could a freshwater swamp produce a chemical signature characteristic of a saltmarsh?
Reduction–oxidation (redox) reaction conditions, which are of great importance for the soil chemistry of coastal marshes, can be temporally dynamic. We present a transect of cores from northwest Florida wherein radical postdepositional changes in the redox regime has created atypical geochemical profiles at the bottom of the sedimentary column. The stratigraphy is consistent along the...

The physical characteristics of the sediments on and surrounding Dauphin Island, Alabama The physical characteristics of the sediments on and surrounding Dauphin Island, Alabama
Scientists from the U.S. Geological Survey, St. Petersburg Coastal and Marine Science Center collected 303 surface sediment samples from Dauphin Island, Alabama, and the surrounding water bodies in August 2015. These sediments were processed to determine physical characteristics such as organic content, bulk density, and grain-size. The environments where the sediments were collected...

Sediment lithology and radiochemistry from the back-barrier environments along the northern Chandeleur Islands, Louisiana—March 2012 Sediment lithology and radiochemistry from the back-barrier environments along the northern Chandeleur Islands, Louisiana—March 2012
Scientists from the U.S. Geological Survey (USGS) St. Petersburg Coastal and Marine Science Center collected a set of 8 sediment cores from the back-barrier environments along the northern Chandeleur Islands, Louisiana, in March 2012. The sampling efforts were part of a larger USGS study to evaluate effects on the geomorphology of the Chandeleur Islands following the construction of an...

Evaluating the potential effects of hurricanes on long-term sediment accumulation in two micro-tidal sub-estuaries: Barnegat Bay and Little Egg Harbor, New Jersey, U.S.A. Evaluating the potential effects of hurricanes on long-term sediment accumulation in two micro-tidal sub-estuaries: Barnegat Bay and Little Egg Harbor, New Jersey, U.S.A.
Barnegat Bay, located along the eastern shore of New Jersey, was significantly impacted by Hurricane Sandy in October 2012. Scientists from the U.S. Geological Survey (USGS) developed a multidisciplinary study of sediment transport and hydrodynamics to understand the mechanisms that govern estuarine and wetland responses to storm forcing. This report details the physical and chemical

Sedimentologic characteristics of recent washover deposits from Assateague Island, Maryland Sedimentologic characteristics of recent washover deposits from Assateague Island, Maryland
The U.S. Geological Survey has a long history of responding to and documenting the impacts of storms along the Nation’s coasts and incorporating these data into storm impact and coastal change vulnerability assessments. Although physical changes caused by tropical and extratropical storms to the sandy beaches and dunes fronting barrier islands are generally well documented, the...

A seasonal comparison of surface sediment characteristics in Chincoteague Bay, Maryland and Virginia, USA A seasonal comparison of surface sediment characteristics in Chincoteague Bay, Maryland and Virginia, USA
Scientists from the U.S. Geological Survey, St. Petersburg Coastal and Marine Science Center conducted a seasonal collection of surficial sediments from Chincoteague Bay and Tom's Cove, between Assateague Island and the Delmarva Peninsula in late March/early April 2014 and October 2014. The sampling efforts were part of a larger U.S. Geological Survey study to assess the effects of storm...
