GNIS-LD: Serving and visualizing the Geographic Names Information System Gazetteer as linked data
Blake Regalia, Krzysztof Janowicz, Gengchen Mai, Dalia E. Varanka, E. Lynn Usery
2018, Conference Paper, The semantic web; 15th International Conference, ESWC 2018, Heraklion, Crete, Greece, June 3–7, 2018, Proceedings
In this dataset description paper we introduce the GNIS-LD, an authoritative and public domain Linked Dataset derived from the Geographic Names Information System (GNIS) which was developed by the U.S. Geological Survey (USGS) and the U.S. Board on Geographic Names. GNIS provides data about current, as well as historical, physical,...
The National Elevation Dataset
Dean B. Gesch, Gayla A. Evans, Michael J. Oimoen, Samantha T. Arundel
2018, Book chapter
The National Elevation Dataset (NED) is a primary elevation data product that has been produced and distributed by the U.S. Geological Survey (USGS). Since its inception, the USGS has compiled and published topographic information in many forms, and the NED is a significant development in this long line of products...
Analysis of population change and movement using robust design removal data
William A. Link, Sarah J. Converse, Amy A. Yackel Adams, Nathan J. Hostetter
2018, Journal of Agricultural, Biological, and Environmental Statistics (23) 463-477
In capture-mark-reencounter studies, Pollock’s robust design combines methods for open populations with methods for closed populations. Open population features of the robust design allow for estimation of rates of death or permanent emigration, and closed population features enhance estimation of population sizes. We describe a similar design, but for use...
Hydrogeochemical controls on brook trout spawning habitats in a coastal stream
Martin A. Briggs, Judson W. Harvey, Stephen T. Hurley, Donald O. Rosenberry, Timothy D. McCobb, Dale D. Werkema, John W. Lane Jr.
2018, Hydrology and Earth System Sciences (22) 6383-6398
Brook trout (Salvelinus fontinalis) spawn in fall and overwintering egg development can benefit from stable, relatively warm temperatures in groundwater-seepage zones. However, eggs are also sensitive to dissolved oxygen concentration, which may be reduced in discharging groundwater (i.e., seepage). We investigated a 2 km reach of the coastal Quashnet River in...
Predicting biological conditions for small headwater streams in the Chesapeake Bay watershed
Kelly O. Maloney, Zachary M. Smith, Claire Buchanan, Andrea Nagel, John A. Young
2018, Freshwater Science (4) 795-809
A primary goal for Chesapeake Bay watershed restoration is to improve stream health and function in 10% of stream miles by 2025. Predictive spatial modeling of stream conditions, when accurate, is one method to fill gaps in monitoring coverage and estimate baseline conditions for restoration goals. Predictive modeling can also...

Shamsher Sadiq, Okan Ilkan, Sean K Ahdi, Yousef Bozorgina, Youssef M.A. Hashash, Dong Youp Kwak, Duhee Park, Alan Yong, Jonathan P. Stewart
2018, Conference Paper
We describe the data model that we intend to use in a publicly available site profile database under development for the United States. The initial implementation of the database contains data from California. Currently, our prototype data model consists of JavaScript Object Notation (JSON) format files for storing metadata and...

2018, Conference Paper, Geothermal's role in today's energy market
Recent geologic and geophysical investigations were undertaken in northeastern Oregon to better assess earthquake hazards in the region and determine relative favorability for geothermal energy development on lands of the Confederated Tribes of the Umatilla Indian Reservation (CTUIR). This work was funded in part by a Bureau of Indian Affairs...
Estimating metal concentrations with regression analysis and water-quality surrogates at nine sites on the Animas and San Juan Rivers, Colorado, New Mexico, and Utah
M. Alisa Mast
2018, Scientific Investigations Report 2018-5116
The purpose of this report is to evaluate the use of site-specific regression models to estimate metal concentrations at nine U.S. Geological Survey streamflow-gaging stations on the Animas and San Juan Rivers in Colorado, New Mexico, and Utah. Downstream users could use these regression models to determine if metal concentrations...
The conceptual schema in geospatial data standard design with application to GroundWaterML2
Boyan Brodaric, Eric Boisvert, Peter Dahlhaus, Sylvain Grellet, Alexander Kmoch, Francois Letourneau, Jessica Lucido, Bruce Simons, Bernhard Wagner
2018, Open Geospatial Data, Software and Standards (3) 1-15
The explosive growth of geospatial data has stimulated the development of many standards aimed at decreasing data heterogeneity and enhancing data use. Well-established design methods for geospatial data standards typically involve the creation of two schemas for data structure, designated here as logical and physical, but this can lead to...

2018, Open-File Report 2018-1170
Dauphin Island and Little Dauphin Island, collectively, make up a geomorphically complex barrier island system located along Alabama’s southern coast, separating Mississippi Sound from the Gulf of Mexico and Mobile Bay. The barrier island system provides numerous economical (tourism, fisheries) and natural (habitat for migratory birds, natural protection of inland...
Estimating soil respiration in a subalpine landscape using point, terrain, climate and greenness data
Erin Michele Berryman, Melanie K. Vanderhoof, John B. Bradford, Todd Hawbaker, Paul D. Henne, Sean P. Burns, John M. Frank, Richard A. Birdsey, Michael G. Ryan
2018, Journal of Geophysical Research G: Biogeosciences (123) 3231-3249
Landscape carbon (C) flux estimates are necessary for assessing the ability of terrestrial ecosystems to buffer further increases in anthropogenic carbon dioxide (CO2) emissions. Advances in remote sensing have allowed for coarse-scale estimates of gross primary productivity (GPP) (e.g., MODIS 17), yet efforts to assess spatial patterns in respiration lag...

J.L. Wall, Paul Marban, D.F. Brinker, J.D. Sullivan, M. Zimnik, J.L. Murrow, P. C. McGowan, Carl R. Callahan, Diann J. Prosser
2018, Journal of Visualized Experiments (137)
Many waterbird populations have faced declines over the last century, including the common tern (Sterna hirundo), a waterbird species with a widespread breeding distribution, that has been recently listed as endangered in some habitats of its range. Waterbird monitoring programs exist to track populations through time; however, some of the...
Land subsidence along the California Aqueduct in west-central San Joaquin Valley, California, 2003–10
Michelle Sneed, Justin T. Brandt, Michael Solt
2018, Scientific Investigations Report 2018-5144
Extensive groundwater withdrawal from the unconsolidated deposits in the San Joaquin Valley caused widespread aquifer-system compaction and resultant land subsidence from 1926 to 1970—locally exceeding 8.5 meters. The importation of surface water beginning in the early 1950s through the Delta-Mendota Canal and in the early 1970s through the California Aqueduct...

Assessing risks from harbor dredging to the northernmost population of diamondback terrapins using acoustic telemetry
Theodore R. Castro-Santos, M. Bolus, A. J. Danylchuk
2018, Estuaries and Coasts (42) 378-389
The northern diamondback terrapin (Malaclemys terrapin terrapin) is a saltmarsh-dependent turtle that occupies coastal habitats throughout much of the Atlantic coast of North America. We used a novel application of acoustic telemetry to quantify both mobility and occupancy of terrapins within a dredged harbor and surrounding habitats, and used these...

Matthew D. Merrill, Benjamin M. Sleeter, Philip A. Freeman, Jinxun Liu, Peter D. Warwick, Bradley C. Reed
2018, Scientific Investigations Report 2018-5131
In January 2016, the Secretary of the U.S. Department of the Interior tasked the U.S. Geological Survey (USGS) with producing a publicly available and annually updated database of estimated greenhouse gas emissions associated with the extraction and use (predominantly some form of combustion) of fossil fuels from Federal lands. In...
