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

Louisiana Gas and Oil Fields with Cumulative Production from 1977 - 2014
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
Assessing the robustness of quantitative fatty acid signature analysis to assumption violations (Supplementary data)
This dataset contains fatty acid (FA) data expressed as mass percent of total FA for bearded seals, ringed seals and walrus. This is one of many datasets used in Bromaghin et al., In press, Assessing the robustness of quantitative fatty acid signature analysis to assumption violations, Methods in Ecology and Evolution. These supplemental data were used in computer simulations to compare the bias o
Aleutian Arc Fluid Geochemical Data
This report contains the chemical and isotopic data from thermal waters and gases collected from the Aleutian Arc over the past 20 years, where such data remain unpublished or only published in part.
Cape Canaveral, Florida 2010 Single-beam Bathymetry Data
Single-beam bathymetric surveys were conducted on July 27-29, 2010 along 37 cross-shore transects offshore from Cape Canaveral, Fla. The transects were spaced 500 m apart in the alongshore direction and each was approximately 5 km long in the cross-shore.
Laysan Teal Duck Microsatellite Data; Laysan Island 1999-2009, Midway Island 2007-2010
Determine genetic diversity and quantify variation in the endangered Laysan Teal Duck (Anas laysanensis) at microsatellite loci sampled from 230 individuals at Laysan Island (1999-2009) and Midway Island (2007-2010).
Historical methyl mercury in San Francisco Bay
San Francisco Bay, California is considered a mercury-impaired watershed. Elevated concentrations of mercury are found in water and sediment as well as fish and estuarine birds. Sources of mercury to the watershed since 1845 include sediment-associated mercury from mercury mining, mercury losses from gold amalgamation activities in mines of the Sierra Nevada, aerial deposition of mercury from gl
