Seepage meter efficiency in highly permeable settings source data (2020)

Efficiency of seepage meters, long considered a fixed property associated with the meter design, is not constant in highly permeable sediments.  Instead, results from this study indicate that efficiency varies substantially with seepage-bag fullness, duration of bag attachment, depth of meter insertion into the sediments, and seepage velocity.  Efficiency also varies substantially in response to variable hydraulic conductivity.  The first worksheet titled "Literature efficiency" presents seepage-meter efficiency values from the literature to show the progression of efficiency versus time.  The remaining 7 worksheets present time-series data showing seepage-meter efficiency related to several different tests: (1) flow response to a series of bag attachments, (2) effect of bag fullness during upward flow at several seepage rates, (3) efficiency response during long bag attachments at a range of seepage rates, (4) efficiency during upward and downward seepage at a range of seepage rates, (5) efficiency in response to different insertion depths of the seepage cylinder, (6) efficiency in response to variable hydraulic conductivity, and (7) efficiency reduction during a prolonged seepage-meter installation.

Split-beam Echo Sounder and Navigation Data Collected Using a Simrad EK80 Wide Band Transceiver and ES38-10 Transducer During the Mid-Atlantic Resource Imaging Experiment (MATRIX), USGS Field Activity 2018-002-FA

In summer 2018, the U.S. Geological Survey partnered with the U.S Department of Energy and the Bureau of Ocean Energy Management to conduct the Mid-Atlantic Resources Imaging Experiment (MATRIX) as part of the U.S. Geological Survey Gas Hydrates Project. The field program objectives were to acquire high-resolution 2-dimensional multichannel seismic-reflection and split-beam echo sounder data along the U.S Atlantic margin between North Carolina and New Jersey to determine the distribution of methane gas hydrates in below-sea floor sediments and investigate potential connections between gas hydrate dynamics and sea floor methane seepage. MATRIX field work was carried out between August 8 and August 28, 2018 on the research vessel Hugh R. Sharp and resulted in acquisition of more than 2,000 track-line kilometers of multichannel seismic-reflection and co-located split-beam echo sounder data, along with wide-angle seismic reflection and refraction data from 63 expendable sonobuoy deployments.

Historical Produced Water Chemistry Data Compiled for the North Coles Levee Oilfield, Kern County, California

This dataset contains geochemical and other information for 40 historical samples of produced water from the North Coles Levee Oil Field. Three of these samples are from commingled tanks containing produced water from multiple wells as noted in the “Remarks” column. Water that is produced as a byproduct of oil production is called produced water. The numerical water chemistry data were compiled by the U.S. Geological Survey (USGS) from scanned laboratory analysis reports available from the California Geologic Energy Management Division (CalGEM). Sample site characteristics, such as well construction details, were attributed using a combination of information provided with the scanned laboratory analysis reports and well history files from CalGEM Well Finder. The data were transferred manually into a numerical dataset and organized by specific produced water chemical characteristics. Each sample is identified by its API (American Petroleum Institute) number, latitude and longitude, well name, formation name, perforation interval, and date tested. The geochemical analyses include major ions, some minor ions, total dissolved solids (TDS), pH, specific gravity, resistivity, electrical conductivity, and charge balance. The collection and analysis methods and circumstances under which the historical samples were collected cannot be fully known. The intent is to use these historical data in grouped analysis including many sample results, rather than detailed interpretation of each individual sample. Caution should be used in basing interpretations of the data on single sample results.

Unvegetated to Vegetated Ratio in coastal wetlands along the U.S. Gulf of Mexico Coast (16-bit GeoTIFF)

Prior research has shown that sediment budgets, and therefore stability, of microtidal marsh complexes scale with areal unvegetated to vegetated marsh ratios (UVVR) suggesting these metrics are broadly applicable indicators of microtidal marsh vulnerability. This effort has developed the UVVR metric using Landsat 8 satellite imagery for the coastal areas of the contiguous United States (CONUS). These datasets provide annual averages of 1) developed, 2) vegetated, 3) unvegetated fractional covers and 4) an unvegetated to vegetated ratio (UVVR) at 30-meter resolution over the coastal areas of the contiguous United States for the years 2014-2018. Additionally, multi-year average values of vegetated fractional cover and its standard deviation are provided for the coastal wetlands of the contiguous United States based on the National Wetland Inventory delineation. Finally, a UVVR based on the annually-averaged vegetated fractional cover is also provided for the same extent.

Airborne electromagnetic, magnetic, and radiometric survey, upper East River and surrounding watersheds near Crested Butte, Colorado, 2017

This data release consists of 1,984 line-kilometers of airborne electromagnetic (AEM), magnetic data and radiometric data collected from October to November 2017 in the upper East River and surrounding watersheds in central Colorado. The U.S. Geological Survey contracted Geotech Ltd. to acquire these data as part of regional investigations into the geologic structure and hydrologic framework of the area. The AEM data have been inverted to produce a series of regional cross-sections that constrain the electrical properties of the subsurface to a depth of ~500m. Data were acquired using the VTEM ET time-domain helicopter-borne electromagnetic system along flight lines that cross important geological structures over a 483 square kilometer area. In addition to magnetic and radiometric data, this data release includes minimally processed AEM data, processed AEM data used in the development of resistivity and induced polarization (IP) models, and laterally constrained inverse models for resistivity and IP parameters along all flight lines. Data that intersected cultural infrastructure have been removed from the processed AEM data prior to inversion. 
The data provided in this section include laterally-constrained inverted resistivity models and plotted depth sections along all flight lines. Digital data are described in the data dictionary and additional details regarding data inversion are described in the metadata processing steps.

Multidecadal Streamflow Trends and Ecological Flow Statistics at USGS Streamgages within the Chesapeake Bay Watershed (1940-2018)

The hydrologic regime of rivers and streams is a major determinant of habitat quality for fish and aquatic invertebrates. Long-term streamflow data were compiled and multidecadal streamflow trends and ecological flow (EFlow) statistics were calculated in support of the United States Geological Survey (USGS) Chesapeake Bay Science Initiative toward understanding fish habitat and health in the Chesapeake Bay Watershed (CBWS). A dataset comprising all streamgages (n = 409) reporting daily means of streamflow within the CBWS and remaining active as of September 30, 2018 (the end of Water Year [WY] 2018), independent of streamgage installation date, was retrieved from the USGS National Water Information System (NWIS). This dataset was then subset to include only those streamgages with a contiguous timeseries of streamflow data from a start date no earlier than April 1, 1939 (Climate Year [CY] 1940) and no later than October 1, 1999 (WY 2000). The R packages “EGRET” and "Eflowstats" were utilized together to determine streamflow trends and EFlow statistics from the subset (n = 243). Trends and EFlows were computed for the ranges 1940-1969 (n = 90), 1970-1999 (n = 167), and 2000-2018 (n = 243). Streamflow trends were computed for eight annual metrics (1-, 7- and 30-day minima [CY] and maxima [WY], mean and median [WYs]). These streamflow trends provide context for the 178 EFlow statistics (WY) which have been designated to characterize the magnitude, frequency, and duration of extreme high and low flows, the timing of seasonal flows, and the consistency of the historic regime. Files herein include the following Child Items: (1) a table summarizing streamflow trends for three time periods at a minimum of 90 and maximum of 243 streamgages and 500 time-series plots graphically representing those trends; (2) a table summarizing EFlow statistics and the change between each statistic for three time periods at a minimum of 90 and maximum of 243 streamgages; and (3) a GIS shapefile of the original 409 USGS streamgage locations, complete with NWIS attributes, active within the CBWS through September 30, 2018.

Data Release of hydrogeologic data from the San Antonio Creek Valley watershed, Santa Barbara County, California, 2015-2019

The San Antonio Creek Valley watershed (SACVW) is located in western Santa Barbara County about 15 miles (mi) south of Santa Maria, California and 55 mi north of Santa Barbara, California. The SACVW, is about 140 square miles and encompasses the San Antonio Creek Valley groundwater basin. Since the late 1800s, groundwater has been the primary source of water for agricultural, military, municipal, and domestic uses. Groundwater withdrawal from pumping has exceeded the amount of water replenishing the basin, causing groundwater declines of more than 150 feet in parts of the valley between 1947 and 2018, and reducing base flow in San Antonio Creek at the western end of the SACVW. Agricultural water use (primarily for the present-day irrigation of vineyards, and fruit and berry crops), and the lack of other sources of water, has, and will continue to strain the sustainability of the groundwater system. To address these concerns, the Santa Barbara County Water Agency and Vandenberg Space Force Base invited the U.S. Geological Survey (USGS) to engage in a cooperative study to develop a better understanding of the hydrogeologic system, and to provide tools to help evaluate and manage the effects of future development of the San Antonio Creek Valley groundwater basin, and in the encompassing SACVW. Datasets collected as part of this effort were used to assist in the development a numerical integrated hydrologic model of the SACVW. As part of this study the USGS collected hydrogeologic field data and developed a three-dimensional hydrogeologic framework model (HFM) of the SACVW. Hydrogeologic field data included streambed infiltrometer and aquifer slug tests, and measurements from streambed electrical resistivity instruments and temperature rod sensors. The HFM provided a quantitative framework of the aquifer system, including the thickness and extent of each of six hydrogeologic units that comprise the basin-fill aquifer. Infiltrometer tests provided data that can be used to estimate infiltration rate, streambed hydraulic conductivity and specific yield in the SACVW. Aquifer slug tests provided data that can be used to estimate hydraulic conductivity of aquifer units. Streambed electrical resistivity instruments provided data that can be used to estimate stream intermittency and flow patterns, and temperature rod sensors provided data that can be used to estimate streamflow infiltration.
