Data

This data set contains time series and spatial measurements of discrete seawater samples analyzed for carbonate system parameters including water temperature (degrees C), salinity, pHT (pH on the total scale), dissolved oxygen (mg/L), total alkalinity (micromol/kg), dissolved inorganic carbon (DIC) (micromol/kg), nitrate + nitrite (micromol/L), nitrite (micromol/L), silicate (micromol/L), ammonium

This data release provides 667-line kilometers (km) of processed single-beam bathymetry (SBB) data and 773-line km of processed Interferometric Bathymetry (IFB) collected by the USGS SPCMSC in July 2016 (field activity number [FAN] 2016-347-FA). The IFB were acquired on board the Research Vessel (R/V) Sallenger (subFAN, 16BIM04), and the SBB was acquired on board the R/V Jabba Jaw (subFAN, 16BIM05

This data set contains time series measurements of carbonate system parameters including water temperature (?C), conductivity (siemens), pressure (dbars), salinity, pHT (pH on the total scale), carbon dioxide (ppm), dissolved oxygen (micromol/L), and photosynthetically active radiation (microEinsteins). These data were collected in Tampa Bay, Florida by the U.S. Geological Survey (USGS) St. Peters

The U.S. Geological Survey (USGS), as part of the National Assessment of Coastal Change Hazards (NACCH) conducts baseline and storm-response photography missions to document and understand the changes in the vulnerability of the Nation's coasts to extreme storms and longer-term processes related to sediment supply and sea-level rise. On October 13?15, 2016, the USGS's NACCH project conducted an ob

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 the Texas coastline. Elevation measurements were acquired by the Experimental Advanced Airborne Research Lidar (EAARL) on September 17th, 2008, following Hurricane Ike landfall.

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 the Texas coastline. Elevation measurements were acquired by the Experimental Advanced Airborne Research Lidar (EAARL) on September 27th and 28th, and October 2nd, 2005, following Hurricane Rita landfall.

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

Acoustic Doppler Current Profilers (ADCPs) and Pressure loggers were deployed at Crocker Reef, a senile (dead) barrier reef located in the northern portion of the Florida Reef Tract during December 12, 2014 to January 30, 2015. A pressure logger was deployed in the deepest part of the fore reef at a water depth of 14 m. This logger configured to measure pressure at a rate of 2 Hz to obtain wave st

Attenuation Factor (AF; Rao and others, 1985) and DRASTIC (Aller and others, 1987) models were developed for the Upper Floridan aquifer within the Southwest Florida Water Management District (SWFWMD) boundaries. The models were compared to assess the ability of each of these models to indicate the vulnerability of groundwater resources to contamination by Ethylene Dibromide and Bromacil pesticides

Provided here are the SWAN wave model input of grid 4 with pit 3 configuration and output of significant wave height, dominant wave period, and mean wave direction resulting from simulation of wave scenarios at the Breton Island, LA, as described in USGS Open-File Report 2015-1055 (https://doi.org/10.3133/ofr20151055). There are 128 individual scenarios that are based on significant wave height (H

These datasets, prepared cooperatively by the U.S. Geological Survey St. Petersburg Coastal and Marine Science Center and the National Park Service (NPS), provide lidar-derived first-surface and bare-earth topography for a portion of eastern Louisiana. Elevation measurements were acquired by the Experimental Advanced Airborne Research Lidar (EAARL) on March 9, 2008.

The U.S. Army Corps of Engineers contracted a beach survey of Fire Island, New York from September 17-October 6, 2013 for the purpose of planning of a beach reconstruction project following Hurricane Sandy. This dataset contains elevation data of subaerial morphology and nearshore bathymetry collected using real time kinematic global positioning system (RTK-GPS) and hydrography techniques. The dat
