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...

This data release serves as an archive of sediment physical properties and grain-size data for surficial samples collected offshore of Assateague Island, Maryland and Virginia, for comparison with surficial estuarine and subaerial sedimentological samples collected and assessed following Hurricane Sandy (Ellis and others, 2015; Smith and others, 2015; Bernier and others, 2016). The...

In support of studies and assessments of barrier island evolution in the Gulf of Mexico, rates of shoreline change for Dauphin Island, Alabama, were calculated using two different shoreline proxy datasets with a total temporal span of 75 years. Mean High Water line (MHW) shorelines were generated from 14 lidar datasets from 1998 to 2014, and Wet Dry Line (WDL) shorelines were digitized...

Dauphin Island, Alabama is a barrier island located in the Northern Gulf of Mexico that supports local residences, tourism, commercial infrastructure, and the historical Fort Gaines. During the past decade, Dauphin Island has been impacted by several major hurricanes (Ivan, 2004; Katrina, 2005; Isaac, 2012). Storms, along with sea level rise, present a continued threat to island...

These datasets, prepared by the U.S. Geological Survey St. Petersburg Coastal and Marine Science Center in collaboration with the National Park Service, provide lidar-derived first-surface and bare-earth topography for Cape Cod National Seashore, Massachusetts. Elevation measurements were acquired by the Experimental Advanced Airborne Research Lidar (EAARL) during October 2002.

The U.S. Geological Survey conducted experiments during March of 2014 to expand the available data on sand and oil agglomerate motion; test shear stress based incipient motion parameterizations in a controlled, laboratory setting; and directly observe sand and oil agglomerate exhumation and burial processes. Experiments were carried out at the Naval Research Laboratory, Stennis Space...

Indian River Lagoon, one of the most biologically diverse estuarine systems in the continental United States, is a shallow brackish lagoon stretching along approximately 200 kilometers (km) of the Atlantic coast of central Florida. Lagoon width varies from ~0.5 - 9.0 km, with substantial human infrastructure lining both shores. Scientists from the U.S. Geological Survey (USGS) St...

These datasets, prepared by the U.S. Geological Survey St. Petersburg Coastal and Marine Science Center, provide lidar-derived first-surface and bare-earth topography for a portion of northwest Florida. Elevation measurements were acquired by the Experimental Advanced Airborne Research Lidar (EAARL) in September 2005, immediately following Hurricane Katrina landfall.

The National Assessment of Coastal Change Hazards project exists to understand and predict storm impacts to our nation's coastlines. This data defines the alongshore extent of overwash deposits attributed to coastal processes during Hurricane Matthew.

Fire Island, New York is the site of a long term coastal morphologic change and processes project conducted by the U.S. Geological Survey (USGS). One of the objectives of the project was to understand the morphologic evolution of the barrier system on a variety of time scales (months-years-decades-centuries). In response to Hurricane Sandy (October 2012), this effort continued with the...

These datasets, prepared by the U.S. Geological Survey St. Petersburg Coastal and Marine Science Center, provide lidar-derived first-surface and bare-earth topography for the Chandeleur Islands, Louisiana. Elevation measurements were acquired by the Experimental Advanced Airborne Research Lidar (EAARL) on September 1?4, 2005, immediately following Hurricane Katrina's landfall.

The files in this data release are the raw DNA sequence files referenced in the submitted journal article by Christina A. Kellogg, Dawn B. Goldsmith and Michael A. Gray entitled "Biogeographic comparison of Lophelia-associated bacterial communities in the western Atlantic reveals conserved core microbiome." They represent a 16S rRNA gene amplicon survey of the coral's microbiomes...
