Projected flood water depths on Roi-Namur, Kwajalein Atoll, Republic of the Marshall Islands Projected flood water depths on Roi-Namur, Kwajalein Atoll, Republic of the Marshall Islands
Projected future wave-driven flooding depths on Roi-Namur Island on Kwajalein Atoll in the Republic of the Marshall Islands for a range of climate-change scenarios. This study utilized field data to calibrate oceanographic and hydrogeologic models, which were then used with climate-change and sea-level rise projections to explore the effects of sea-level rise and wave-driven flooding on...
Water level and velocity measurements from the 2012 University of Western Australia Fringing Reef Experiment (UWAFRE) Water level and velocity measurements from the 2012 University of Western Australia Fringing Reef Experiment (UWAFRE)
This data release contains water level and velocity measurements from wave runup experiments performed in a laboratory flume setting. Wave-driven water level variability (and runup at the shoreline) is a significant cause of coastal flooding induced by storms. Wave runup is challenging to predict, particularly along tropical coral reef-fringed coastlines due to the steep bathymetric...
High-resolution bathymetry and acoustic-backscatter data collected in 2004, 2005, 2007, and 2010 in Skagit Bay, Washington High-resolution bathymetry and acoustic-backscatter data collected in 2004, 2005, 2007, and 2010 in Skagit Bay, Washington
This data release provides the U.S. Geological Survey (USGS) Pacific Coastal and Marine Science Center (PCMSC) 2004, 2005, 2007, and 2010 bathymetry data that was collected in Skagit Bay, Washington as well as a merged 2005-2010 bathymetry grid. Also, this data release provides the acoustic-backscatter as a merged 2005-2010 backscatter image. All bathymetry grids are provided at 1-m...
Data in support of 5-year sediment budget and morphodynamic analysis of Elwha River following dam removals Data in support of 5-year sediment budget and morphodynamic analysis of Elwha River following dam removals
Two large dams were removed from the Elwha River in Washington, starting in 2011 and ending in 2014. The Elwha and the Glines Canyon dams were located approximately 7 km and 20 km upstream, respectively, from the Elwha River's mouth on the Strait of Juan de Fuca. The dams trapped over 20 million cubic meters of sediment. Dam removal changed the river's sediment budget and water flow...
Olowalu chronology and geochemistry time-series, West Maui Olowalu chronology and geochemistry time-series, West Maui
Chronology and time-series geochemistry data of a coral core collected from Olowalu, West Maui, Hawaii. The chronology is based on density banding, radiocarbon bomb-curve, and uranium thorium dating techniques. The geochemistry time-series data contains major and minor elements over the length of the coral life span, as measured from laser ablation inductively coupled mass spectrometry...
Multibeam and multichannel sparker seismic-reflection data between Cross Sound and Dixon Entrance, offshore southeastern Alaska, collected from 2016-05-17 to 2016-06-12 during field activity 2016-625-FA Multibeam and multichannel sparker seismic-reflection data between Cross Sound and Dixon Entrance, offshore southeastern Alaska, collected from 2016-05-17 to 2016-06-12 during field activity 2016-625-FA
Multibeam bathymetry and multisparker data were collected along the Queen Charlotte-Fairweather Fault between Icy Point and Dixon Entrance, offshore southeastern Alaska from 2016-05-17 to 2016-06-12.
Multichannel sparker seismic-reflection data of field activity 2016-656-FA; between Icy Point and Dixon Entrance, Gulf of Alaska from 2016-08-07 to 2016-08-26 Multichannel sparker seismic-reflection data of field activity 2016-656-FA; between Icy Point and Dixon Entrance, Gulf of Alaska from 2016-08-07 to 2016-08-26
This data release contains high-resolution multichannel seismic (MCS) reflection data collected in August of 2016 along the southeast Alaska continental margin. Structure perpendicular MCS profiles were collected along the Queen Charlotte-Fairweather fault. The data were collected aboard the R/V Norseman using a Delta sparker sound source and recorded on a 64-channel digital streamer...
River-channel topography, grain size, and turbidity records from the Carmel River, California, before, during, and after removal of San Clemente Dam River-channel topography, grain size, and turbidity records from the Carmel River, California, before, during, and after removal of San Clemente Dam
The San Clemente Dam, built in the 1920s on the Carmel River in Monterey County, California, was removed during 2014 and 2015. The dam-removal project was the largest in California to date, and one of the largest in the U.S. This USGS data release presents data collected before, during, and after the removal of the dam. The data were collected to study how the river channel's topographic...
Hydrodynamic and sediment transport data from San Pablo Bay and China Camp marsh (northern San Francisco Bay), 2013-2016 Hydrodynamic and sediment transport data from San Pablo Bay and China Camp marsh (northern San Francisco Bay), 2013-2016
The U.S. Geological Survey Pacific Coastal and Marine Science Center collected data to investigate sediment dynamics in the shallows of San Pablo Bay and sediment exchange between bay shallows and the tidal salt marsh in China Camp State Park in a series of deployments between December 2013 and June 2016. This data release includes two related groups of data sets. The first group...
Beach topography and nearshore bathymetry of northern Monterey Bay, California Beach topography and nearshore bathymetry of northern Monterey Bay, California
This data release presents beach topography and nearshore bathymetry data from repeated surveys in northern Monterey Bay, California to document changes in shoreline position and coastal morphology as they relate to episodic (storms), seasonal, and interannual and longer (e.g. El Ni?o) processes. The ongoing monitoring program was initiated in October 2014 with semi-annual surveys...
Bathymetry, topography, and sediment grain-size data from the Elwha River delta, Washington Bathymetry, topography, and sediment grain-size data from the Elwha River delta, Washington
Two dams on the Elwha River, Washington State, USA trapped over 20 million cubic meters of sediment, reducing downstream sediment fluxes and contributing to erosion of the river's coastal delta. The removal of the Elwha and Glines Canyon dams between 2011 and 2014 induced massive increases in river sediment supply and provided an unprecedented opportunity to examine the response of a...
