Sidescan-sonar Image of the Western Portion of the John Day Reservoir - Washington State Plane South

A two-week field operation was conducted in the John Day Reservoir on the Columbia River to image the floor of the pool, to measure the distribution and thickness of post-impoundment sediment, and to verify these geophysical data with video photography and bottom sediment samples. The field program was a cooperative effort between the USGS Coastal and Marine Geology Team of the Geologic Division and the USGS Columbia River Research Laboratory of the Biological Resources Division. The data collection was completed aboard the R/V ESTERO during September 13-27, 2000. The interest in sediment accumulation in the reservoir was two-fold. First, it was unknown how effective this reservoir was as a sediment trap to material that otherwise would have been transported down-river to the estuary and eventually to the ocean. The recent erosion of beaches along the Washington coast has been attributed to a decreased contribution of sediment from the Columbia River to the coastal system due to the damming of the river. Second, sediment accumulation on the floors of reservoirs along the Columbia River has been suggested to be diminishing salmon spawning grounds. The extent of changes in habitat since construction of the John Day Dam, however, had not been documented. Common data sets were needed to address both of these questions, and for these reasons this geophysical and sampling program was undertaken.

Hawaiian hoary bat radio-tracking roost fidelity, Hawaii Island 2018-2019

Hawaiian hoary bats (Lasiurus cinereus semotus) were captured at multiple locations on the east side of Hawaii Island from May 2018 through September 2019. Radio transmitters were affixed to captured bats and, when possible, radio telemetry was used to locate bats in trees used for day-roosts. Repeated visits to confirm bat presence were conducted until radio-tagged bats were no longer detected at roosts. A total of 56 bats (40 male; 16 female; 55 adult; 1 juvenile) were captured and radio-tagged, and of these, 33 were tracked to roost (23 male; 10 female; 32 adult; 1 juvenile) of either stand- or tree-level. For this subset of 33 bats, the number of distinct days with confirmed occupancy of a bat at roost at either the stand- or tree-level ranged from 1 to 15 days (mean = 5.0 days). The use of multiple roosts at the stand-level were observed for 8 bats; the remaining 25 were only observed at a single roost during the period of monitoring (i.e., until visually confirmed as absent or no radio-tag signal was detected from the roost). Of the subset of eight bats observed at multiple roosts, five were recorded at two roosts, two were recorded at three roosts, and one was recorded at four roosts. The observed frequency of alternating roost trees (“roost switching”) ranged from one (four bats), two (two bats), three (one bat) and eight (one bat).

National Atmospheric Deposition Program Pollen Study Data for 2021 Pollen Season

Pollen was measured in ambient air by several methods and in wet atmospheric deposition samples at three monitoring sites in the National Atmospheric Deposition Program (NADP) National Trends Network. A method for counting pollen on filters was developed and provided pollen counts for NADP atmospheric wet-deposition samples and high-volume ambient air samplers (HVAS) for comparison with co-located traditional microscopy and PollenSense sensor counting methods during the 2021 pollen season. Air and precipitation samples were collected by the NADP and analyzed by the Wisconsin State Laboratory of Hygiene, in Madison, Wisconsin and Aerobiology Research Laboratories (Canada).   Daily data were obtained from online summaries released by the National Allergy Bureau.  Ten-minute records of pollen concentration measurements were obtained from the PollenSense network.  Use of trade of firm names is for description purposes only and does not constitute endorsement by the U.S. government or the University of Wisconsin.

Elevation of the regional transgressive unconformity underlying the inner shelf of Long Bay (Grid; transgr_grd)

In 1999, the U.S. Geological Survey (USGS), in partnership with the South Carolina Sea Grant Consortium, began a study to investigate processes affecting shoreline change along the northern coast of South Carolina, focusing on the Grand Strand region. Previous work along the U.S. Atlantic coast shows that the structure and composition of older geologic strata located seaward of the coast heavily influences the coastal behavior of areas with limited sediment supply, such as the Grand Strand. By defining this geologic framework and identifying the transport pathways and sinks of sediment, geoscientists are developing conceptual models of the present-day physical processes shaping the South Carolina coast. The primary objectives of this research effort are: 1) to provide a regional synthesis of the shallow geologic framework underlying the coastal upland, shoreface and inner continental shelf, and define its role in coastal evolution and modern beach behavior; 2) to identify and model the physical processes affecting coastal ocean circulation and sediment transport, and to define their role in shaping the modern shoreline; and 3) to identify sediment sources and transport pathways; leading to construction of a regional sediment budget.
This data set contains a surface depicting the elevation of the regional transgressive unconformity underlying the inner shelf of Long Bay, offshore of the South Carolina Grand Strand. Chirp seismic data collected with Benthos SIS-1000 and Edgetech SB-512 acquisition systems were processed using SIOSEIS (Scripps Institute of Oceanography) and Seismic Unix (Colorado School of Mines) to produce segy files and jpg images of the profiles. Data were then imported into Landmark SeisWorks, a digital seismic interpretation package, where the sea floor and underlying transgressive surface were interpreted and digitized. The isopach between these horizons was exported at every 50th shot as xyz points, and imported to ArcGIS for interpolation into a 10-m raster grid. The isopach grid was then subtracted from a seafloor bathymetry grid (bathy_grd) to approximate the proper elevation of the transgressive unconformity beneath the sea floor.

Baseline for the Florida west coast (FLwc) coastal region generated to calculate shoreline change rates using the Digital Shoreline Analysis System version 5

During Hurricane Irma in September 2017, Florida and Georgia experienced significant impacts to beaches, dunes, barrier islands, and coral reefs.  Extensive erosion and coral losses result in increased immediate and long-term hazards to shorelines that include densely populated regions. These hazards put critical infrastructure at risk to future flooding and erosion and may cause economic losses. The USGS Coastal and Marine Hazards Resources Program (CMHRP) is assessing hurricane-induced coastal erosion along the southeast US coastline and implications for vulnerability to future storms.

Groundwater-quality data in the Butte-Sutter-Yuba Domestic-Supply Aquifer Study Unit, 2021: Results from the California GAMA Priority Basin Project

The U.S. Geological Survey collected groundwater samples from 38 wells used for domestic and small system drinking water supplies in Butte, Sutter, and Yuba counties of California during 2021. The wells were sampled for the Butte-Sutter-Yuba Domestic-Supply Aquifer Study Unit of the State Water Resources Control Board Groundwater Ambient Monitoring and Assessment (GAMA) Program Priority Basin Project’s assessment of the quality of groundwater resources used for domestic and small system drinking water supplies. The study unit was defined by the extent of the Butte, Los Molinos, North and South Yuba, Sutter, Vina, and Wyandotte Creek groundwater subbasins of the Sacramento Valley and an uplands area adjacent and to east of these subbasins within Butte County. The study unit was divided into a total of 40 grid cells across two study areas with 25 grid cells in the Sacramento Valley study area and 15 in the Upland study area. One or more domestic or small system wells were sampled in 38 of the 40 of the grid cells. Groundwater samples were analyzed for field water-quality parameters, volatile organic compounds, pesticides and pesticide degradants, stable isotopes of water, nutrients, major ions and trace elements, hexavalent chromium, perchlorate, per- and polyfluoroalkyl substances (PFAS), and microbial indicators. Groundwater levels were measured in 25 of the 38 wells sampled.

Geomorphic Reference Reach Data for the Kalamazoo River Basin, Michigan Area of Concern: Kalamazoo River Between Trowbridge Dam and Allegan, Michigan, 2023

The datasets contained in this data release represent the results of a geomorphic assessment of the Kalamazoo River to identify and characterize reference reaches that are applicable analogues for dam removal and restoration sites in various channel and valley settings along the Kalamazoo River from the city of Kalamazoo downstream through the towns of Plainwell and Allegan. Data are included from four reference reaches in a 15 km section between Trowbridge Dam and Allegan, MI that were identified based on variations in valley confinement, channel planform, hydraulic geometry, and gradient. Reference Reach 1 (furthest upstream) had a single-thread planform, partial valley confinement, an average gradient of 0.079% and average bankfull width of 83.4 m. Reference Reach 2 was in a section of multi-thread channel planform, was laterally unconfined, and had an average gradient of 0.049% and bankfull width of 64.0 m. Reference Reach 3 had single-thread planform, was laterally unconfined, and had an average gradient of 0.059% and bankfull width of 66.2 m. Reference Reach 4 had single-thread planform, was laterally confined within a narrow valley, and had an average gradient of 0.014% and bankfull width of 64.6 m.
The reference reach data include channel cross-sections, valley-spanning cross-sections, a longitudinal profile, mapped hydrogeomorphic units, and substrate size data. Each of these data types are contained in separate child items accessible from the main ScienceBase landing page. Data from all four reaches are included in each child item. These geomorphic data are delivered in a variety of file formats, organized in a nested structure. Details on the overall structure and organization of the files in the data release are contained in a README file. Additional details on methods, accuracy and potential uses of the datasets are contained within the metadata files associated with each particular dataset.

Coastwide Reference Monitoring System (CRMS) 2005, 2008, 2012, 2016 and 2018 Site 2830 land-water matrix

Wetland restoration efforts conducted by the Coastal Wetlands Planning, Protection and Restoration Act (CWPPRA) in Louisiana rely on monitoring to determine the efficacy of these projects. The Coastwide Reference Monitoring System (CRMS) was developed to assist in a multiple-reference approach that uses aspects of hydrogeomorphic functional assessments and probabilistic sampling for monitoring. The CRMS program includes a suite of approximately 390 sites that encompass the range of hydrological and ecological conditions for each stratum. As part of CRMS, land and water classifications are created from Digital Orthophoto Quarter Quadrangles (DOQQs) approximately every three years at all CRMS sites. This dataset consists of a matrix of five land-water products (2005, 2008, 2012, YYYY and 2018).  The resulting matrix has 32 possible classes defined by the combination of land and water categories on those five dates.

Digital Elevation Model (DEM) for basin A1

Unmanned Aerial System (UAS) flights were conducted over four stream catchments in Rio Blanco County, Colorado, during the summer of 2016. Two sties had active oil and gas operations within the basin whereas the other two sites did not.  Structure from motion (SfM) was used to align raw images and create a dense point cloud, georectified orthoimage, and Digital Elevation Model (DEM) for each basin.  A Digital Terrain Model (DTM), or bare earth model, for each basin was created by reclassifying the dense point cloud as either bare ground or other (vegetation, oil and gas infrastructure, etc.) and interpolating the land surface between bare ground points.  Ideally, the DTM would always be equal or lower than the DEM; however, the interpolated surface can sometimes be higher than the DEM if bare ground points surround depressions with vegetation or in thick vegetation strands with an undulating surface. Therefore, a final surface model, created by merging the DTM with the DEM for all areas where the DTM was greater than the DEM, was produced for each basin. Lastly, a random forest classification approach was used to classify the orthoimagery on a pixel level into five vegetation/land cover classifications - bare ground, grass, litter, shrub/woody vegetation, and shadow.

Raw Continuous Resistivity Profiles from Cape Cod National Seashore, May 17, 2004

Continuous resistivity profiling (CRP) surveys were conducted at Cape Cod National Seashore in 2004 and 2006 in order to test hypotheses about groundwater flow under and into estuaries and the Atlantic Ocean. Coastal resource managers here and elsewhere are concerned about nutrients that are entering coastal waters via submarine groundwater discharge, which are contributing to eutrophication and harmful algal blooms. CRP is used to measure electrical resistivity of sediments, a property that is sensitive to differences in salinity of submarine ground water. The 2004 and 2006 surveys used floating resistivity streamers of 100 m and 50 m respectively. The depth penetration of the streamers is approximately 20% of the streamer length which translates to approximately 20-25 m with the 100 m streamer and 12-14 m with the 50 m streamer. These data were processed using AGI's EarthImager 2D software.
