The U.S. Geological Survey, Woods Hole Coastal and Marine Science Center in cooperation with the University of Maine mapped approximately 50 square kilometers of the seafloor within Belfast Bay, Maine. Three geophysical surveys conducted in 2006, 2008 and 2009 collected swath bathymetric (2006 and 2008) and chirp seismic reflection profile data (2006 and 2009). The project characterized the spatial, morphological and subsurface variability of the Belfast Bay, Maine pockmark field. Pockmarks are large seafloor depressions that are associated with seabed fluid escape.

This point shapefile approximates locations within 20 km of the North Pacific Coastline, as defined by the "World Country Boundaries (Generalized)" shapefile distributed by ESRI as part of their Data & Maps data series. They are based on raster data at 4 km resolution. Therefore there are between 3-5 points extending out from each location along the shoreline (at 4 km intervals).

USGS developed The National Map (TNM) Gazetteer as the Federal and national standard (ANSI INCITS 446-2008) for geographic nomenclature based on the Geographic Names Information System (GNIS). The National Map Gazetteer contains information about physical and cultural geographic features, geographic areas, and locational entities that are generally recognizable and locatable by name (have achieved some landmark status) and are of interest to any level of government or to the public for any purpose that would lead to the representation of the feature in printed or electronic maps and/or geographic information systems. The dataset includes features of all types in the United States, its associated areas, and Antarctica,...

A three-dimensional hydrogeologic framework model (3D HFM) of the westernmost western Snake River Plain (WSRP) aquifer system was prepared to represent the subsurface distribution and thickness of four hydrogeologic units. The primary source of data for the 3D HFM was lithologic data from a total of 291 well-driller reports. These data were then processed using Rockware Rockworks17 three-dimensional modeling software. The data released here are grouped into three datasets: (1) An ASCII text file of the 3D HFM containing XYZ data. (2) Comma-delineated CSV files containing well information including lithology. (3) An MP4 video file showing the 3D HFM model as it is revealed by slices and then rotated.

The U.S. Geological Survey (USGS) works closely with the Mississippi Department of Transportation (MDOT) to provide information to be used by the MDOT for design of highway-drainage structures. MDOT spends millions of dollars annually for highway construction. Streamflow records, hydrologic analyses of basins, and hydraulic analyses of flooding potential at proposed highway crossings help the MDOT to make more informed decisions on the use of highway construction funding. Flood-frequency and hydraulic characteristics at highway crossings are determined from historical flood-elevation data recovered by the USGS, cross-section data, and correlations with data from nearby gaging stations. Additional streamflow data...

In 2009, the Kootenai Tribe of Idaho released and implemented the Kootenai River Habitat Restoration Master Plan. This plan aimed to restore, enhance, and maintain the Kootenai River habitat and landscape to support and sustain habitat conditions for aquatic species and animal populations. In support of these restoration efforts, the U.S. Geological Survey, in cooperation with the Kootenai Tribe of Idaho, conducted high-resolution multibeam echosounder bathymetric surveys, velocity surveys, and collected images of substrate in the Lower Meander Reach (RM 143 - 145.5) and Straight Reach (RM 151 - 152). This data release contains bathymetry, velocity, and substrate data from surveys performed on the Kootenai River...

Starting in 1999, WBPHS_AK surveyors used the custom survey software RECORD (John I. Hodges, FWS-MBM-Alaska, retired) to record bird data and capture the survey flight track. Each observer had their own computer and obtained their own separate flight track each day. The track was recorded by capturing a GPS location every 5 seconds as long as the survey software was running. The software was started at some time between the aircraft’s engine start and the first transect, and was shut down at some time between the last transect and engine shut-down. The track thus includes the aircraft’s flight to and from transects as well as along the transects themselves.This collection comprises the track files from 1999 to present:...

The Geographic Names Information System (GNIS) is the Federal standard for geographic nomenclature. The U.S. Geological Survey developed the GNIS for the U.S. Board on Geographic Names, a Federal inter-agency body chartered by public law to maintain uniform feature name usage throughout the Government and to promulgate standard names to the public. The GNIS is the official repository of domestic geographic names data; the official vehicle for geographic names use by all departments of the Federal Government; and the source for applying geographic names to Federal electronic and printed products of all types. See http://geonames.usgs.gov for additional information.

Map of the Agashashok River Area and location of proposed observation sites (numbered circles). This focal watershed is in the southwest corner of the Arctic LCC and largely drains the Brooks Range ecoregion with a small portion of the lower basin in the Kobuk Ridges and Valleys ecoregion. The braided character of the lower river prevents us from suggesting a long term gaging station in that location. Inset shows the location of the seven TEON focal watersheds. Image by Arctic LCC staff.

The earthquake catalog was generated in August 2018 using the standard National Seismic Hazard Model methodology (Mueller, 2019) for the central and eastern United States. Pre-existing catalogs were merged, duplicate records were removed, the catalog was declustered, and induced earthquakes were removed. The final catalog contains 6802 records, M2.5–7.8, and extends from 1568 through July 2018.

This geopackage contains the density strata that were used to create the YKD Coastal Zone Survey’s current four-year rotating panel design. This file was derived from a mid-1980’s ArcInfo coverage, ‘Sampling Intensity’ (“SI arc”) that was produced through the visual interpretation of 1:250,000-scale LANDSAT imagery and the nesting density of cackling Canada geese.

California’s Coastal Data Information Program (CDIP) has a hind cast feature that allows one to model hourly height and period at known locations back to 2000. Fitting these hindcasts to observed height and periods indicates that the hindcasts have consistent biases that can be corrected for statistically. Past work generated bias corrections for 32 sites in the Channel Islands. We use these bias corrections to correct hourly height and period hindcasts at these sites from 2000 to 2017. Data columns include: year_utc, month_utc, day_utc, hour_utc, cdip_Hs_m, cdip_Tp_sec, cdip_Dp_degTrue, adjusted_cdip_Hs_m, mean_sensor_pressure_dbar, Transect_depth_m, ubr_Sensor, Tbr_sensor, wave_energy, date, juliand, season, wyr,...
This sampling frame is a set of grid-based finite-area frames spanning Canada, the United States, and Mexico. The grid for the United States is broken into individual grids for the continental United States, Hawaii, and Puerto Rico. Alaska is combined with Canada into a single grid. Each country/state/territory extent consists of four nested sampling grids at 50x50km, 10x10km, 5x5km, and 1x1km resolutions. The original 10x10km continental United States grid was developed by the Forest Service, U.S. Department of Agriculture for use in the interagency “Bat Grid” monitoring program in the Pacific Northwest and was expanded across Canada, the United States, and Mexico for the North American Bat Monitoring Program (NABat)....

The natural resiliency of the New Jersey barrier island system, and the efficacy of management efforts to reduce vulnerability, depends on the ability of the system to recover and maintain equilibrium in response to storms and persistent coastal change. This resiliency is largely dependent on the availability of sand in the beach system. In an effort to better understand the system's sand budget and processes in which this system evolves, high-resolution geophysical mapping of the sea floor in Little Egg Inlet and along the southern end of Long Beach Island near Beach Haven, New Jersey was conducted from May 31 to June 10, 2018, followed by a sea floor sampling survey conducted from October 22 to 23, 2018, as part...

In spring and summer 2017, the U.S. Geological Survey’s Gas Hydrates Project conducted two cruises aboard the research vessel Hugh R. Sharp to explore the geology, chemistry, ecology, physics, and oceanography of sea-floor methane seeps and water column gas plumes on the northern U.S. Atlantic margin between the Baltimore and Keller Canyons. Split-beam and multibeam echo sounders and a chirp subbottom profiler were deployed during the cruises to map water column backscatter, sea-floor bathymetry and backscatter, and subsurface stratigraphy associated with known and undiscovered sea-floor methane seeps. The first cruise, known as the Interagency Mission for Methane Research on Seafloor Seeps and designated as field...

288 adult and yearling female elk were captured on 22 Wyoming winter supplemental elk feedgrounds and monitored with GPS collars during the brucellosis risk period (February – July) from 2007 to 2015. There were 4 to 64 individual elk per feedground and each elk was monitored for 1 to 2 years. Here we provide the unique identifier for each individual elk, the GPS location of the elk, the date/time stamp of the GPS location, and the feedground the elk was captured on in Wyoming.
