HW1_Q27.TIF - Hawaii I - Southeastern Hawaiian Ridge U.S. EEZ GLORIA sidescan-sonar data mosaic (27 of 29) (LCC, 50 m, WGS84)

Survey of the southeastern Hawaiian Ridge was the fifth major segment of the Exclusive Economic Zone (EEZ) mapping program to have been initiated. Data acquisition for this region required approximately one-half year and were acquired during eight cruises over a four year period from 1986 through 1989, skipping 1987. At the conclusion of the survey 29 mosaics of a 2 degree by 2 degree were completed for the region. As in earlier EEZ reconnaissance surveys, the USGS utilized the GLORIA (Geological LOng-Range Inclined Asdic) sidescan-sonar system to complete the geologic mapping. The collected GLORIA data were processed and digitally mosaicked to produce continuous imagery of the seafloor. A total of twenty-seven digital mosaics of a 2 degree by 2 degree area and 2 mosaics of 2.25 degree by 2 degree with a 50-meter pixel resolution were completed for the region.

Projected Seafloor Elevation Along the Florida Reef Tract From Deerfield Beach to Homestead, Florida—50 Years From 2014 Based on Historical Rates of Mean Erosion

The U.S. Geological Survey (USGS) St. Petersburg Coastal and Marine Science Center conducted research to quantify the combined effect of all constructive and destructive processes on modern coral reef ecosystems by projecting future regional-scale changes in seafloor elevation for several sites along the Florida Reef Tract, Florida (FL) including the shallow seafloor along the coast of Miami, FL. USGS staff used historical bathymetric point data from the 1930's (National Oceanic and Atmospheric Administration (NOAA) Office of Coast Survey, see Yates and others, 2017) and light detection and ranging (lidar)-derived data acquired in 2002 (Brock and others, 2006, 2007) to calculate historical seafloor elevation changes in the Upper Florida Keys (UFK) (Yates and others, 2017). Using those changes in seafloor elevation, annual rates of erosion were calculated for 13 habitat types found in the UFK reef tract. The annual rate of mean erosion for each habitat type was applied to a digital elevation model (DEM) extending from Deerfield Beach to Homestead, FL that was modified from the NOAA National Centers for Environmental Information (NCEI) Miami coastal DEM (NOAA, 2015) to project future seafloor elevation (from 2014) along the Miami section of the Florida Reef Tract. Grid resolution for the DEM is 1/3 arc second (approximately 10 meters).

DS-777 Annual Model-Forecasted Land-Use/Land-Cover Rasters from 2009 to 2050 for the B2 Climate Scenario for the High Plains Aquifer in Parts of Colorado, Kansas, Nebraska, New Mexico, Oklahoma, South Dakota, Texas, and Wyoming

Estimates of area and aerial extent of land-use categories are an essential component 
for computing the water budget of the High Plains aquifer. These raster land-use land 
class data represent yearly simulated future land use for the High Plains from 2009 to 
2050 These data were developed using the FOREcasting SCEnarios (FORE-SCE) of 
future land cover model (Sohl and others, 2007; Sohl and Sayler 2008) for two (A2 and 
B2) of the four Intergovernmental Panel on Climate Change (IPCC) climate scenarios 
and then processed using a Geographic Information System (GIS). The GIS software 
used to process these data was Environmental Systems Research Institute (ESRI, Inc.) 
ArcGIS Desktop 10.0.

Sediment Sample Locations Collected in August 2015 from Dauphin Island and the surrounding areas

Scientists from the U.S. Geological Survey, St. Petersburg Coastal and Marine Science Center collected 303 surface sediment samples from Dauphin Island, Alabama, and the surrounding water bodies in August 2015. These sediments were processed to determine physical characteristics such as organic content, bulk density, and grain-size. The environments where the sediments were collected include high and low salt marshes, over-wash deposits, dunes, beaches, sheltered bays, and open water. Sampling by the USGS was part of a larger study to assess the feasibility and sustainability of proposed restoration efforts for Dauphin Island, Alabama, and assess the island's resilience to rising sea level and storm events. The data presented in this publication can be used by modelers to attempt validation of hindcast models and create predictive forecast models for both baseline conditions and storms. This study was funded by the National Fish and Wildlife Foundation, via the Gulf Environmental Benefit Fund. This report serves as an archive for sedimentological data derived from surface sediments. Downloadable data are available as Excel spreadsheets, JPEG files, and formal Federal Geographic Data Committee metadata (data downloads).

Channel centerline for the Nehalem River, Oregon in 2009

The Tillamook Bay subbasins and Nehalem River basins encompass 1,369 and 2,207 respective square 
kilometers of northwestern Oregon and drain to the Pacific Ocean. The Tillamook, Trask, Wilson, Kilchis, 
and Miami Rivers flow into Tillamook Bay near the towns of Tillamook and Garibaldi. The Wilson and 
Trask River basins cover the largest areas (500 and 451 square kilometers, respectively) whereas the 
Tillamook and Kilchis Rivers encompass similar sized areas (156 and 169 square kilometers, respectively) 
and the Miami River the smallest area (94 square kilometers). In cooperation with the U.S. Army Corps 
of Engineers, the U.S. Geological Survey completed a reconnaissance-level assessment of channel 
condition and bed-material transport relevant to the permitting of in-stream gravel extraction along the 
major alluvial portions of six river systems, including the lowermost 14.1 km of the Tillamook River, 
16.3 km of the Trask River, 15.2 km of the Wilson River, 7.8 km of the Kilchis River, 11.6 km of the 
Miami River, and 31.4 km of the Nehalem River. To support these analyses, digital channel maps 
were produced to depict channel and floodplain conditions in the Tillamook Bay sub-basins and 
Nehalem River basin from different time periods. GIS layers defining the wetted channel and bar 
features and channel centerline in the study area were developed for four time periods: 1939, 1967, 
2005, and 2009. For this project, the active channel was defined as area typically inundated during 
annual high flows, and includes the low-flow channel as well as side channels, islands, and channel-
flanking gravel bars. The wetted channel and bar feature datasets were developed by digitizing from 
aerial photographs. Aerial photographs from 1939 and 1967 were scanned, rectified, and mosaicked 
for this project (See metadata for each photograph set for more information on the rectification process 
and resolution of each dataset). Digital orthophotographs from 2005 and 2009 are publicly available.

LANDFIRE 2016 Remap Elevation (Elev) American Samoa

IA DEM was produced from 1/3rd arc-second downloaded from viewer.nationalmap.gov/basic. The 3DEP 1/3rd arc-second DEMs, previously referred to as the National Elevation Dataset (NED), are derived from diverse source data, processed to a common coordinate system and unit of vertical measure.  All 3DEP data are distributed in geographic coordinates in units of decimal degrees, and in conformance with the North American Datum of 1983 (NAD 83).  All elevation values are provided in units of meters, and are referenced to the North American Vertical Datum of 1988 (NAVD 88) over the conterminous United States. For the LANDFIRE Elevation product, the 1/3 arc-second 3DEP DEM data were projected from geographic to Albers Equal Area, resampled to 30m spatial resolution, and clipped out to the IA 0k boundary.

Projected Seafloor Elevation Change and Relative Sea Level Rise Near St. Croix, U.S. Virgin Islands 25, 50, 75, and 100 Years from 2014

The U.S. Geological Survey (USGS) St. Petersburg Coastal and Marine Science Center conducted research to quantify bathymetric changes near Buck Island and St. Croix, U.S. Virgin Islands. Changes in seafloor elevation were calculated using historical bathymetric point data from the 1980s (see Yates and others, 2017a) and light detection and ranging (lidar)-derived data acquired in 2014 (NOAA, 2015) using methods outlined in Yates and others (2017b). An elevation change analysis between the 1980s and 2014 data was performed to quantify and map historical impacts to seafloor elevation and to determine elevation-change statistics for 12 habitat types found near St. Croix. Annual elevation-change rates were calculated for each elevation-change data point. Seafloor elevation-change near St. Croix was projected 25, 50, 75 and 100 years from 2014 using these historical annual rates of elevation change. Water depth was projected 25, 50, 75 and 100 years from 2014 using historical rates of annual elevation change plus 2014 local sea level rise (SLR) data from the National Oceanic and Atmospheric Administration (NOAA).

Boundary of the Eagle River Watershed Valley-Fill Aquifer, Eagle County, North-Central Colorado, 2006-2007

This vector data set delineates the approximate boundary of the Eagle River watershed valley-fill aquifer (ERWVFA). 
This data set was developed by a cooperative project between the U.S. Geological Survey, Eagle County, the Eagle 
River Water and Sanitation District, the Town of Eagle, the Town of Gypsum, and the Upper Eagle Regional Water 
Authority. This project was designed to evaluate potential land-development effects on groundwater and surface-water 
resources so that informed land-use and water management decisions can be made. The boundary of the ERWVFA 
was developed by combining information from two data sources. The first data source was a 1:250,000-scale geologic 
map of the Leadville quadrangle developed by Day and others (1999). The location of Quaternary sediments was used 
as a first approximation of the ERWVFA. The boundary of the ERWVFA was further refined by overlaying the geologic 
map with Digital Raster Graphic (DRG) scanned images of 1:24,000 topographic maps (U.S. Geological Survey, 2001). 
Where appropriate, the boundary of the ERWVFA was remapped to correspond with the edge of the valley-fill aquifer 
marked by an abrupt change in topography at the edge of the valley floor throughout the Eagle River watershed. The 
boundary of the ERWVFA more closely resembles a hydrogeomorphic region presented by Rupert (2003, p. 8) because 
it is based upon general geographic extents of geologic materials and not on an actual aquifer location as would be 
determined through a rigorous hydrogeologic investigation.

Underwater temperature on off-shore coral reefs of the Florida Keys, U.S.A. (Version 9)

The U.S. Geological Survey (USGS) Coral Reef Ecosystems Studies (CREST) project (https://coastal.er.usgs.gov/crest/) provides science that helps resource managers tasked with the stewardship of coral reef resources. Coral reef organisms are very sensitive to high and low water-temperature extremes. Therefore, it is critical to precisely know water temperatures experienced by corals and associated plants and animals that live in the dynamic nearshore environment to document thresholds in temperature tolerance. This data release provides underwater temperature data recorded every fifteen minutes from 2009 to 2024 at ten offshore coral reefs in the Florida Keys, USA. From southwest to northeast, these sites are in Dry Tortugas National Park: Garden Key, Pulaski Shoal West, Pulaski Shoal Light; in the Florida Keys National Marine Sanctuary: Sombrero Reef, Crocker Reef, Molasses Reef; and in Biscayne National Park: Ball Buoy North, Shadow Reef, Brewster Reef, and Fowey Rocks. Measurements were made at Sombrero Reef from July 2009 to August 2022, at Crocker Reef from June 2013 to August 2022, and at Molasses Reef from April 2009 to April 2013. Data collection continues at three sites in the Dry Tortugas National Park (Pulaski West, initiated December 2016, Garden Key, initiated May 2022, and Pulaski Light, initiated June 2009) and four sites in Biscayne National Park (Fowey Rocks, initiated August 2009, and Ball Buoy North, Shadow Reef, and Brewster Reef initiated in May 2023). The data release will continue to be updated, as more data are collected. Portions of the dataset included here were interpreted in conjunction with coral and/or algal calcification rates in publications including Kuffner and others (2020) and Lenz and others (2021). See the cross-reference section of the metadata for a complete list of related publications.
