MBES bathymetry of Lake Michigan nearshore near Ogden Dunes/Burns Harbor, Indiana, September 8, 2016

These data are high-resolution bathymetry (lake bottom elevation) in XYZ format, generated from the September 8, 2016, topographic and hydrographic survey of Lake Michigan in an area near Ogden Dunes, Indiana. Hydrographic data were collected using a multibeam echo-sounder (MBES) with integrated inertial navigation solution (INS) mounted on a marine survey vessel. Data were collected as the vessel traversed the lake along survey lines distributed throughout the area. Data collection software integrated and stored the depth data from the multibeam sonar and the horizontal and vertical position and attitude data of the vessel from the INS in real time. Data processing required computer software to extract bathymetric data from the raw data files and to summarize and map the information.

RTK-dGPS surveys of Lake Michigan beach topography near Ogden Dunes/Burns Harbor, Indiana

The US Army Corps of Engineers (USACE) is evaluating the placement of dredged material in the nearshore areas of Lake Michigan as a means to replenish sand at selected beaches. In order to elucidate the physical processes in the nearshore environment that transport and distribute sand to the beach, the USACE-Chicago District and the US Geological Survey (USGS) developed a plan for a beach replenishment study on Lake Michigan near Burns Harbor/Ogden Dunes, Indiana. In support of this effort, a backpack-mounted Trimble Ag132 RTK-dGPS was used for two surveys of beach topography (August 9, 2016, and October 11, 2016) in the study area.

Dissolved organic matter data in water samples from Penobscot River, Penobscot Bay, and the Gulf of Maine, 2008

The sampling of the riverine-to-marine transect (Penobscot River, Penobscot Bay, and the Gulf of Maine) took place in 2008. Water samples were collected and filtered in the field using 0.45 micrometer capsule filters (Versapor membrane), silicon tubing, and a peristaltic pump. Water samples were then shipped on ice to the U.S. Geological Survey in Boulder, Colorado and chilled to approximately 4 degrees Celsius until analysis. Dissolved organic matter (DOM) was separated into fractions by an isolation method that passes aqueous sample through Amberlite XAD8 and XAD4 resins using low pressure liquid chromatography. The hydrophobic organic acid (HPOA) fraction is the eluate from the XAD8 fractionation column and the transphilic organic acid (TPIA) fraction is the eluate from the XAD4 fractionation column.  Dissolved organic carbon (DOC) was either analyzed on a Shimadzu TOC-Vcph total organic carbon analyzer by combustion-infrared or an OI700 Analytical total organic carbon analyzer by wet-oxidation; each sample was measured in replicate and the average was reported. Ultraviolet (UV) absorbance at the wavelength of 254 nm was measured with an Agilent HP8453 UV-Vis spectrophotometer. Specific UV Absorbance (SUVA) at 254 nm is a calculated parameter defined as the UV absorbance at a wavelength of 254 nm in absorbance units per centimeter divided by the DOC concentration in milligrams per liter and then multiplied by 100. SUVA 254 nm is reported in units of liters per milligram carbon per meter and correlates with the percent aromatic carbon of the DOM.  Associated laboratory quality assurance and quality control measures have been taken to produce final data.

Upward-profiling ADCP wave and current measurements from Lake Michigan near Ogden Dunes/Burns Harbor, Indiana

The US Army Corps of Engineers (USACE) is evaluating the placement of dredged material in the nearshore areas of Lake Michigan as a means to replenish sand at selected beaches. In order to elucidate the physical processes in the nearshore environment that transport and distribute sand to the beach, the USACE-Chicago District and the US Geological Survey (USGS) developed a plan for a beach nourishment study on Lake Michigan near Burns Harbor/Ogden Dunes, Indiana. In support of this effort, the USGS deployed an upward-profiling acoustic Doppler current profiler (ADCP) to the Burns Harbor/Ogden Dunes study area to collect wave and current data. The ADCP was located at the following World Geodetic System 1984 (WGS84) coordinates: 41⁰37’44.90" N, -87⁰12’06.90" W. This metadata file describes the wave parameters and current data exported from the Teledyne RDI Waves software package.

Effects of Hillslope Gully Stabilization on Erosion and Sediment Production in the Torreon Wash Watershed, New Mexico, 2009–2012 - Associated Data

Sediment erosion and deposition in two sets of paired (treated and untreated) upland drainages in the Torreon Wash watershed, upper Rio Puerco Basin, New Mexico, were examined over a 3 1/2-year period from spring 2009 through fall 2012. The objective was to evaluate the effectiveness of shallow, loose-stone check dams, or “one-rock dams,” as a hillslope gully erosion stabilization and mitigation method, and its potential for retaining upland eroded soils and decreasing delivery of sediment to lower ephemeral stream channels. Two high-resolution topographic surveys, completed at the beginning and end of the study period, were used to assess the impact of the mitigation measures in both Penistaja Tributary Arroyo and Papers Wash watersheds, and at six mainstem-channel cross-section clusters along Penistaja Tributary Arroyo and Papers Wash tributary in the Torreon Wash watershed.  This data release contains the survey data, constructed cross sections, and associated precipitation data collected for the analysis used in this study.

Geochemical analyses of rock samples collected from mineral deposits and intrusions of the Bokan Mountain peralkaline granitic complex, Prince of Wales Island, southeastern Alaska

This data set compiles the major and trace element chemistry of rock samples collected by the U.S. Geological Survey (USGS) at Bokan Mountain, located in the southern part of Prince of Wales Island, southeastern Alaska. Bokan Mountain was formed by an Early Jurassic peralkaline igneous complex that intruded into lower Paleozoic rocks of the Alexander terrane of southeast Alaska. The pluton and surrounding country rocks host numerous mineral deposits and occurrences, including heavy rare earth element (HREE)-rich pegmatites and felsic dikes, as well as mineral deposits rich in uranium, thorium, HREE, and fluorine. The Ross-Adams mine on Bokan Mountain exploited a uranium-thorium deposit intermittently from the late 1950s to 1971, and remains the only uranium producer in Alaska. Recent exploration by Ucore Rare Metals Inc. (http://ucore.com/) at Bokan Mountain has focused on the Dotson and I and L Zones, which together form a 2.5-km-long, 50 m-wide zone of thin felsic dikes and pegmatites (each rarely more than 2-m-wide) that are enriched in rare earth elements (REE). Ucore Rare Metals has reported an inferred resource for the combined zones as 5.275 million metric tons of ore at 0.654 percent total REE oxides, using a cutoff of 0.4 percent total REE oxides; about 40 percent of the total REE oxides in these dikes and pegmatites are the HREE (http://ucore.com/Ucore_43-101.pdf). 
This data release provides the analytical results of 153 rock hand samples collected by USGS geologists during site visits to Bokan Mountain in 2010, 2011, and field studies during 2014. The samples represent a variety of rock types associated with the Bokan Mountain igneous complex, including mineral deposits, prospects and occurrences, along with examples of unaltered intrusions of the pluton. The samples were analyzed for 55 major and trace elements using inductively coupled plasma-atomic emission spectrometry (ICP-AES) and inductively coupled plasma-mass spectrometry (ICP-MS) and also analyzed for major elements using wavelength dispersive x-ray fluorescence spectrometry (WDXRF). This data set is provided for future use in geologic, exploration, and environmental background studies of Bokan Mountain and its mineral deposits.

Elk abundance and seroprevalence data in southern GYE 1993-2015

We calculated mean adult and yearling female elk abundance for each Wyoming winter supplemental feedground subpopulation for data collected from 2009 to 2015. In addition, the average seroprevalence of brucellosis in elk attending feedgrounds was based on blood samples from adult and yearling female elk from 1993 to 2015. The sample size of disease tests and the number of years over which they were collected on each feedground are also listed. Serological profiles were categorized using the 2003 U.S. Department of Agriculture brucellosis eradication uniform methods and rules for cervids. These serological tests indicate whether or not an individual has been exposed, but not whether they are currently infected.

Predicted daily elk abortion events in southern GYE 2010, 2012, 2014

Using data from 288 adult and yearling female elk that were captured on 22 Wyoming winter supplemental elk feedgrounds and monitored with GPS collars, we fit Step Selection Functions (SSFs) during the spring abortion season and then implemented a master equation approach to translate SSFs into predictions of daily elk distribution for 5 plausible winter weather scenarios (from a heavy snow, to an extreme winter drought year). We then predicted abortion events by combining elk distributions with empirical estimates of daily abortion rates, spatially varying elk seroprevalence, and elk population counts. Here we provide the predicted abortion events on a daily basis at a 500m resolution for the 5 different weather scenarios: 1) low snowfall year (2010), 2) average snowfall year (2012), 3) high snowfall year (2014), 4) hypothetical early snowmelt climate change scenario where spring green up started, snow melt occurred, and supplemental feeding ended 14 days earlier than in the low snow year of 2010, and 5) hypothetical winter drought climate change scenario where spring green up started, snow melt occurred, and supplemental feeding ended 28 days earlier than in the low snow year of 2010.

Chesapeake Bay Nontidal Network 1985-2016: WRTDS input data

Nitrogen, phosphorus, and suspended-sediment loads, and changes in loads, in rivers across the Chesapeake Bay watershed have been calculated using monitoring data from the Chesapeake Bay Nontidal Network (NTN) stations for the period 1985 through 2016. Nutrient and suspended-sediment loads and changes in loads were determined by applying a weighted regression approach called WRTDS (Weighted Regression on  Time, Discharge, and Season).  The load results represent the total mass of nitrogen, phosphorus, and suspended sediment that was exported from each of the NTN watersheds.

Molecular detection of avian influenza virus from sediment samples in waterfowl habitats on the Delmarva Peninsula, USA

Data were collected as part of an investigation developed by Leetown Science Center to investigate the comparative detection of avian influenza viruses from waterfowl and potential environmental reservoirs such as aquatic sediment from waterfowl habitat. This dataset identifies positive or negative test results for qRT-PCR (quantitative reverse transcriptase polymerase chain reaction) for avian influenza virus through identification of the Type A influenza virus matrix gene from aquatic sediment samples.  Sediment samples were collected from waterfowl habitat so as to determine if temporal and spatial differences in virus detection by qRT-PCR were evident among test sites.

Oxide and Cation Compositions of Olivine Grains from Drill Core in the Duluth Complex, Minnesota

The table contains oxide and cation compositions of olivine grains from drill core of the Duluth Complex, Minnesota. The oxides were determined by electron probe microanalysis (EPMA) and are reported in weight percent (wt%). The cations were calculated based on the oxide compositions and are reported in mole percent (mol%). Olivine is a magnesium iron orthosilicate mineral with the formula (Mg2+, Fe2+)2SiO4. Olivine forms a solid solution series with magnesium (Mg) at one end and iron (Fe) at the other. Forsterite (Mg2SiO4) is the magnesium endmember and fayalite (Fe2SiO4) is the iron endmember. Minor elements can substitute into the crystal structure, such as manganese (Mn) and nickel (Ni). To better understand the chemical composition of the measured olivine grains, the percent forsterite (Fo), also known as the magnesium number (Mg#), and the percent fayalite (Fa) were calculated.
