Wetland-Change Data Derived from Landsat Imagery, Assateague Island to Metompkin Island, Maryland and Virginia, 1984 to 2015

This data release includes geospatial datasets that were created to analyze wetland changes along the Virginia and Maryland Atlantic coasts between 1984 and 2015 as part of the U.S. Geological Survey's (USGS) Barrier Island and Estuarine Wetland Physical Change Assessment. Wetland change was determined by assessing two metrics: wetland persistence and land-cover switching. Because seasonal water l

Single-Beam Bathymetry Data Collected in 2015 Nearshore Dauphin Island, Alabama

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 stability. State a

Barrier-island and estuarine-wetland physical-change assessment after Hurricane Sandy

IntroductionThe Nation’s eastern coast is fringed by beaches, dunes, barrier islands, wetlands, and bluffs. These natural coastal barriers provide critical benefits and services, and can mitigate the impact of storms, erosion, and sea-level rise on our coastal communities. Waves and storm surge resulting from Hurricane Sandy, which made landfall along the New Jersey coast on October 29, 2012, impa

Application of ground penetrating radar for identification of washover deposits and other stratigraphic features: Assateague Island, MD

A combination of ground penetrating radar (GPR) data, core data, and aerial photographs were analyzed to better understand the evolution of two portions of Assateague Island, Maryland. The focus of the study was to investigate the applicability of using GPR data to image washover deposits in the stratigraphic record. High amplitude reflections observed in two shore-perpendicular GPR profiles were

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 interaction between
