California State Waters Map Series--Offshore of Aptos, California

Guy R. Cochrane & Susan A. Cochran
This publication about the Offshore of Aptos map area includes 10 map sheets that contain explanatory text, in addition to this descriptive pamphlet and a data catalog of geographic information system (GIS) files. Sheets 1, 2, and 3 combine data from four different sonar surveys to generate comprehensive high-resolution bathymetry and acoustic-backscatter coverage of the map area. These data reveal a range of physiographic features (highlighted in the perspective views on sheet 4) such as...

Harmonization of Forest Disturbance Datasets of the Conterminous United States from 1986-2011

Christopher E. Soulard
A wide range of spatial forest disturbance datasets exist for the conterminous United States, yet inconsistencies between map products arise because of differing programmatic objectives and methodologies. Researchers harmonized maps from multiple data sources (i.e., Global Forest Change, Landfire Vegetation Disturbance, National Land Cover Database, Vegetation Change Tracker, Web-enabled Landsat Data, and Monitoring Trends in Burn Severity) using a pixel-based data fusion process. The harmonization process, which involves fitting common class ontologies and testing spatial...

Collection-1 Landsat OLI Level-2 Surface Reflectance (SR) Science Product

Landsat satellite data have been produced, archived, and distributed by the U.S. Geological Survey (USGS) since 1972. Users rely on these data for historical study of land surface change, but shoulder the burden of post-production processing to create applications-ready data sets. In compliance with guidelines established through the Global Climate Observing System, USGS has embarked on production of higher-level Landsat data products to support land surface change studies. Terrestrial variables such as surface reflectance are...

Raw Ground Penetrating Radar Data, Eureka Glacier, Alaska; 2013

Daniel McGrath Salvatore G. Candela
Common-offset GPR surveys were conducted with a Sensors and Software 500-MHz Pulse Ekko Pro system. We collected data from the ground, towed behind a researcher on skis or snowmobile, and from the air, strapped underneath a helicopter. All of the profiles are linked to coincident GPS observations. Coincident in-situ data is provided for calibration, and may be composed of any of the following: snow pits and/or snow-pit/snow-core combinations, probe profiles, and ablation stakes. This supplemental...

Louisiana Gas and Oil Fields with Cumulative Production from 1977 - 2014

Scott A Kinney
This dataset represents the producing, dry holes, wildcat wells and wells that have other well type categories other than the ones mentioned previously in Louisiana. These wells were used to create gas and oil field polygons. The field polygons include discovery data, number of producing wells in the field, average measured depth of those well, total gas and oil production from 1977-2014, gas oil ratio (GOR), and field type. Also, included is a table with...

Environmental Studies of Macrozoobenthos, Aquatic Macrophytes, and Juvenile Fishes in the St. Clair-Detroit River System, 1983-1984: Hoopnet Sampling Record for Fish

Bruce M Davis, Patrick L Hudson, Susan J Nichols & Cynthia M Tomcko
This hoopnet sampling record for fish data set was collected for use in the administrative report entitled "Environmental Studies of Macrozoobenthos, Aquatic Macrophytes, and Juvenile Fishes in the St. Clair-Detroit River System, 1983-1984". It is a portion of the data collected for this administrative report, which provided information needed by the U.S. Army Corps of Engineers for preparation of a Supplemental Environmental Impact Statement addressing the winter operation of the lock facilities at Sault Ste....

USGS Dam Removal Science Database

Katherine M. Vittum J. Ryan Bellmore
This database is the result of an extensive literature search aimed at identifying documents relevant to the emerging field of dam removal science. In total the database contains 179 citations that contain empirical monitoring information associated with 130 different dam removals across the United States and abroad. Data includes publications through 2014 and supplemented with the U.S. Army Corps of Engineers National Inventory of Dams database, U.S. Geological Survey National Water Information System and aerial...

Pacific Walrus Coastal Haulout Database 1852-2016

A.S. Fischbach
We summarize Pacific walrus coastal haulout locations reported in published papers, reports, and personal communications from 1893 through 2014. We report haulout locations based on available reports, as well as the authors? personal knowledge of specific haulout locations and publicly available geo-referenced imagery (Digital Globe, Longmont, Colorado, USA) viewed through a virtual digital globe (Google Earth TM). For each haulout location, we provide a brief geographic description indicating the country (Russian Federation or United States),...

Basin Characterization Model of the Great Basin: A Dataset of Historical and Future Hydrologic Response to Climate Change

Alan L. Flint Lorraine E. Flint
This data release for the Great Basin BCM includes a range of downscaled climate and hydrologic-response variables generated from an ensemble of climate projections within the context of the historical hydro-climatology. The Great Basin BCM was developed at a 270-m spatial resolution using methods previously developed and vetted in California (Flint and Flint, 2012; Flint and others, 2013; Thorne and others 2015). Climate inputs included historical data from 1951-2013 and an ensemble of 12 future...

Tracking Water-Quality in the Nation's Streams and Rivers

The U.S. Geological Survey (USGS) National Water-Quality Assessment (NAWQA) Program will characterize the status and trends of water quality and aquatic ecosystems by monitoring ambient water-quality and ecological conditions through a National Fixed Site Network (NFSN).The NFSN includes 102 surface-water stream and river sites across the United States. This annual water-quality reporting Web site is the primary vehicle for the reporting of NFSN data and findings.

Oceanographic measurements for characterizing light attenuation and sediment resuspension in the Barnegat Bay- Little Egg Harbor estuary, New Jersey, 2013

P.K. Dickhudt
The U.S. Geological Survey measured suspended-sediment concentration, currents, waves, light attenuation, and a variety of other water quality parameters in the summer of 2013 in Barnegat Bay, New Jersey. Data were acquired sequentially at three channel and three shoal sites, moving the equipment from south to north in the estuary. Data were collected for approximately 3 weeks at each site.
