Time-series coral-cover data from Hawaii, Florida, Mo'orea, and the Virgin Islands

Coral reefs around the world have degraded over the last half-century as evidenced by loss of live coral cover. This ubiquitous observation led to the establishment of long-term, ecological monitoring programs in several regions with sizable coral-reef resources. As part of the U.S. Geological Survey (USGS) John Wesley Powell Center for Analysis and Synthesis working group "Local-scale ecosystem resilience amid global-scale ocean change: the coral reef example," scientists gathered resultant data from four of these programs in the main Hawaiian Islands, the Florida Keys, Mo'orea in French Polynesia, and St. John in the U.S. Virgin Islands to examine among-site, within-region spatial and temporal variation in coral cover. Data from the four focal regions represent spatial scales ranging from ~80 to 17,000 km2. The surveys chosen for the analysis were carried out at fixed sites between 1992 and 2015. Survey durations differed among focal regions and extended from 11 years at Mo'orea to 24 years at some of the sites in St. John. One hundred and twenty-three fixed sites (defined here as distinct surveys carried out within a defined reef habitat, depth range, or area of shoreline) were surveyed repeatedly (annually or every few years) in each focal region. Only sites with surveys extending over a decade or more and with at least 3 years of surveys were used so as to capture a variety of disturbance events (for example, El Niño events, major storms, etc.). Each focal region has experienced disturbances such as overfishing, disease pandemics, thermal stress, pollution, invasive species, predator outbreaks, and major storms. The data gathered for analysis are provided in this data release and are interpreted in Guest and others (2018).

Yellowstone River Basin study unit boundary, National Water-Quality Assessment Program, scale 1:100,000, Montana, North Dakota, and Wyoming

As part of the U.S. Geological Survey's National Water-Quality
Assessment Program, an investigation of the Yellowstone River Basin
study unit is being conducted to document status and trends in
surface- and ground-water quality.  Efficient quantification of a
variety of environmental and geographic characteristics of the study
unit requires a digital map of the study-unit boundary that may be
processed, together with other digital thematic maps (such as geology
or land use), in a geographic information system (GIS).  Digital
boundary data for the Yellowstone River Basin study unit are included
in this data release.  The boundary follows drainage divides that were
identified chiefly using 1:100,000-scale (50 m accuracy) hypsography.

Lateral boundary of the transient ground-water flow model, Death Valley regional ground-water flow system, Nevada and California

This digital data set defines the lateral boundary and model domain of the area simulated by the transient 
ground-water flow model of the Death Valley regional ground-water flow system (DVRFS). The DVRFS 
transient ground-water flow model is the most recent in a number of regional-scale models developed by 
the U.S. Geological Survey (USGS) for the U.S. Department of Energy (DOE) to support investigations at 
the Nevada Test Site (NTS) and at Yucca Mountain, Nevada (see "Larger Work Citation", Chapter A, page 8, 
for details). The model domain is an approximately 45,000 square-kilometer region of southern Nevada and 
California. The lateral boundary encompassing the model domain is a combination of no-flow boundaries 
resulting from physical barriers or hydraulic separation of flow regimes (ground-water divides and [or] regional 
flow lines) and arbitrary lateral-flow (throughflow) boundaries where ground-water flows across the lateral 
boundary. The lateral boundary is subdivided into 12 segments to reflect boundary conditions.

Single-Beam Bathymetry XYZ Data Collected in 2015 from Grand Bay, Alabama/Mississippi

As part of the Sea level and Storm Impacts on Estuarine Environments and Shorelines project (SSIEES), scientists from the U.S. Geological Survey (USGS) St. Petersburg Coastal and Marine Science Center conducted a single-beam bathymetry survey within the estuarine, open bay and tidal creek environments of Grand Bay Alabama/Mississippi, from May to June 2015. The goal of the SSIEES project is to assess the physical controls of sediment and material exchange between wetlands and estuarine environments along the northern Gulf of Mexico, specifically Grand Bay AL/MS and Vermilion Bay, Louisiana, as well as along the east coast in Chincoteague Bay Virginia/Maryland. The data included in this data release provide baseline bathymetric information for future research investigating wetland/marsh evolution, sediment transport, recent and long term geomorphic change, and can also support modeling of future changes in response to restoration and storm impacts. The survey area encompasses more than 40 square kilometers (km2) of Grand Bay’s incorporated waters. This data release serves as an archive of processed single-beam bathymetry data, collected from May 28 to June 3, 2015 (USGS Field Activity Number [FAN] 2015-315-FA). Geographic information system (GIS) data products include: a 10- and 30-meter cell size interpolated bathymetry grid, trackline maps, and point data files. Additional files include error analysis maps, Field Activity Collection System (FACS) logs, and formal Federal Geographic Data Committee (FGDC) metadata.

Topobathymetric Lidar Survey of Breton and Gosier Islands, Louisiana, January 16 and 18, 2014 - Point-cloud Data

This dataset contains binary point-cloud data, produced from remotely sensed, geographically referenced topobathymetric measurements collected by Photo Science, Inc., encompassing the Breton and Gosier Island, LA study areas. The original area of interest was buffered by 100 meters to ensure complete coverage, resulting in approximately 75 square miles of lidar data.
The Breton Island Lidar project called for the planning, acquisition, processing, and derivative products of topobathymetric lidar data, collected at a nominal pulse spacing (NPS) of 0.5-0.45 meters (4-5 points/square meter). Lidar acquisition was prioritized to coincide with the lowest tide possible. Water clarity was also assessed and deemed acceptable prior to acquisition flights. The data, in meters, are projected to UTM Zone 16 North and referenced horizontally to the NAD83 (2011) datum and vertically to the NAVD88 (GEOID12A) datum. The classified point-cloud data were delivered in LAS v1.2 format and the merged DEM was converted to a GeoTIFF file. Each LAS file contains data in a 1-kilometer by 1-kilometer tile named according to the US National Grid conventions. The final product was a LAZ file for Breton Island and another for Gosier Islands.

2002 USGS Virgina and Maryland Lidar-Derived Dune Crest, Toe and Shoreline

The Storm-Induced Coastal Change Hazards component of the National Assessment of Coastal Change Hazards project focuses on understanding the magnitude and variability of extreme storm impacts on sandy beaches. Lidar-derived beach morphologic features such as dune crest, toe and shoreline help define the vulnerability of the beach to storm impacts. This dataset defines the elevation and position of the seaward-most dune crest and toe and the mean high water shoreline derived from the 2001 Gulf Coast USGS/NASA ATM lidar survey. Beach width is included and is defined as the distance between the dune toe and shoreline along a cross-shore profile. The beach slope is calculated using this beach width and the elevation of the shoreline and dune toe.

Color-Encoded Image of 5-m Gridded Hill-Shaded Bathymetry From Long Island Sound off Bridgeport, Connecticut (H11045_GEO_5MBATHY.TIF, Geographic)

The U.S. Geological Survey, in cooperation with the National Oceanic and Atmospheric Administration and the Connecticut Department of Environmental Protection, has produced detailed geologic maps of the sea floor in Long Island Sound, a major East Coast estuary surrounded by the most densely populated region of the United States.  These studies have built upon cooperative research with the State of Connecticut that was initiated in 1982.  The current phase of this research program is directed toward studies of sea-floor sediment distribution, processes that control sediment distribution, nearshore environmental concerns, and the relation of benthic community structures to the sea-floor geology.
Anthropogenic wastes, toxic chemicals, and changes in land-use patterns resulting from residential, commercial, and recreational development have stressed the environment of the Sound, causing degradation and potential loss of benthic habitats (Koppelman and others, 1976; Long Island Sound Study, 1994). Detailed maps of the sea floor are needed to help evaluate the extent of adverse impacts and to help manage resources wisely in the future.  Therefore, in a continuing effort to better understand Long Island Sound, we have regridded and interpolated this NOAA bathymetric survey into a complete-coverage acoustic image of the sea floor.  The image presented herein covers an area of the sea floor in west-central Long Island Sound off Bridgeport, Connecticut and was produced from data collected during NOAA survey H11045.
This imagery may serve many purposes, including: (1) defining the geological variability of the sea floor, which is one of the primary controls of benthic habitat diversity; (2) improving our understanding of the processes that control the distribution and transport of bottom sediments and the distribution of benthic habitats and associated infaunal community structures; and (3) providing a detailed framework for future research, monitoring, and management activities.  This bathymetry may also serve as a base map for subsequent sedimentological, geochemical, and biological observations, because precise information on environmental setting is important for selection of sampling sites and for accurate interpretation of point measurements.

SEAWAT model used to evaluate water management issues in the Santa Barbara and Foothill groundwater basins, California

The city of Santa Barbara, in cooperation with the U.S. Geological Survey (USGS) California Water Science Center, 
developed a three-dimensional density-dependent groundwater-flow and solute-transport model (the Santa Barbara 
Flow and Transport Model, or SBFTM), based on an existing groundwater-flow model, to simulate seawater intrusion 
into the Santa Barbara basin under various management strategies.  In 2014, California adopted historic legislation 
to manage its groundwater: the Sustainable Groundwater Management Act (SGMA). Santa Barbara is interested in 
developing a better understanding of the sustainability of its groundwater supplies to avoid undesirable results: 
significant and unreasonable groundwater-level declines, reduction in groundwater storage, seawater intrusion, 
water-quality degradation, land subsidence, and surface-water depletion. The SBFTM uses the USGS code 
SEAWAT to simulate salinity transport and variable-density flow. The completed SBFTM was coupled with a 
management optimization tool, Borg, to develop five optimization scenarios that allow the decision makers to 
evaluate a range of optimal solutions given current water levels and chloride concentrations, and possible future 
climatic conditions. This USGS data release contains all of the input and output files for the simulations described 
in the associated model documentation report (https://doi.org/10.3133/sir20185059)

Digital Shoreline Analysis System version 4.3 shoreline intersection points used to calculate long-term shoreline change statistics for the Elizabeth Islands coastal region from Nonamesset Island southwest of Woods Hole to Cuttyhunk Island north of Martha's Vineyard (ElizabethIslands_intersects_LTw.shp)

Due to continued coastal population growth and increased threats of erosion, current data on trends and rates of shoreline movement are required to inform shoreline and floodplain management. The Massachusetts Office of Coastal Zone Management launched the Shoreline Change Project in 1989 to identify erosion-prone areas of the coast. In 2001, a 1994 shoreline was added to calculate both long- and short-term shoreline change rates at 40-meter intervals along ocean-facing sections of the Massachusetts coast.
The Coastal and Marine Geology Program of the U.S. Geological Survey (USGS) in cooperation with the Massachusetts Office of Coastal Zone Management, has compiled reliable historical shoreline data along open-facing sections of the Massachusetts coast under the Massachusetts Shoreline Change Mapping and Analysis Project 2013 Update. Two oceanfront shorelines for Massachusetts (approximately 1,800 km in total length) were (1) delineated using 2008/09 color aerial orthoimagery, and (2) extracted from topographic LIDAR datasets (2007) obtained from NOAA's Ocean Service, Coastal Services Center. The new shorelines were integrated with existing Massachusetts Office of Coastal Zone Management and USGS historical shoreline data in order to compute long- and short-term rates using the latest version of the Digital Shoreline Analysis System (DSAS).
