Polyethylene Particle Detection (counts) during Environmental Sampler Comparison

We designed two new samplers for monitoring airborne particulates, including fungal and fern spores and plant pollen, that rely on natural wind currents (Passive Environmental Sampler) or a battery operated fan (Active Environmental Sampler). Both samplers are modeled after commercial devices such as the Rotorod® and the Burkard® samplers, but are more economical and require less maintenance than commercial devices. We conducted wind tunnel comparisons of our two new samplers to Rotorod® samplers using synthetic polyethylene spheres (12 - 160 µm in diameter) to compare numbers and size range of particulates that are captured by the samplers. This dataset contains raw numbers of polyethylene spheres that were captured by the samplers during eight separate trials in a sealed room with constant recirculating air flow.

Groundwater-Quality Data in the Mojave Basin Shallow Aquifer Study Unit, 2018

The U.S. Geological Survey collected groundwater samples from 49 wells used for domestic and small system drinking water supplies and 10 monitoring wells in San Bernardino County, California in 2018. The wells were sampled for the Mojave Basin (MOBS) Shallow Aquifer Study Unit of the California 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. Domestic and small-system wells commonly are screened at shallower depths than public-supply wells. The MOBS study unit covered the Upper, Middle, and Lower Mojave River groundwater basins, the El Mirage groundwater basin, and part of the Harper groundwater basin [California Department of Water Resources, CA DWR basin designations 6-42, 6-41, 6-40, 6-43, 6-47] in the Desert hydrogeologic province (California Department of Water Resources, 2003; Johnson and Belitz, 2003). Wells in the MOBS study unit generally tap unconsolidated alluvial aquifers composed of sediment eroded from granitic and metamorphic rocks, with portions of aquifer material in the northeast part of the study unit eroded from volcanic rock. The MOBS study unit was divided into two study areas, the floodplain study area along the course of the Mojave River, and the regional study area covering the rest of the study unit. The study areas were further divided into equal area grid cells, with 35 grid cells of 85 square-kilometers each in the regional study area, and 15 grid cells of 29 square-kilometers in the floodplain study area. Domestic or small-system wells were sampled in 48 of the 50 grid cells. The 11 understanding wells (10 monitoring wells and 1 domestic well) were selected to provide additional data for evaluation of the effect of septic systems on groundwater resources used for domestic drinking water supply. Groundwater samples were analyzed for field water-quality parameters, volatile organic compounds, pesticides and pesticide degradates, nutrients, major ions and trace elements, hexavalent chromium, perchlorate, gross alpha and gross beta particle activities, noble gases, tritium, carbon-14 in dissolved inorganic carbon, stable isotopic ratios of water and dissolved nitrate, and microbial indicators. Groundwater levels were measured in nearly all of the sampled wells. All results are presented in this data release, except results for pesticide and pesticide degradates, sulfur hexafluoride, and noble gases.

Organochlorine residues and elemental contaminants in U.S. freshwater fish, 1976-1986: National Contaminant Biomonitoring Program

The National Contaminant Biomonitoring Program (NCBP), which was developed and maintained by the U.S. Fish and Wildlife Service (FWS), monitored concentrations of environmental contaminants in freshwater fish over a period of about 20 years. Beginning in the 1960s as a component of the multi-agency National Pesticide Monitoring Program (NPMP) and continuing through the mid-1980s, freshwater fish were periodically collected from a national network of stations for analysis of pesticides, PCBs, and other contaminants. The NPMP/NCBP database of contaminant concentrations is the most extensive of its kind, unique in its breadth and depth with respect to environmental contaminant concentrations in fish. The data and information from the NCBP are sought often by a national and international clientele; especially frequent users are biologists in FWS field offices and USGS Water Science Centers. The fish network was suspended by FWS in 1986 pending development of the Biomonitoring of Environmental Status and Trends (BEST) program. The BEST program and the NPMP/NCBP database were transferred to the National Biological Survey/Service (NBS) in 1993. At that time ongoing studies by NBS Inventory and Monitoring (I and M) and the USGS National Water Quality Assessment Program (NAWQA) generated new data at NCBP sites. The database was subsequently (1996) transferred to USGS.  The database derived from the NCBP is unique in its ability to characterize the exposure of free-ranging organisms, including threatened and endangered species, to toxic contaminants.

Drainage basins and characteristics for selected streamgages within the Southern Rockies Landscape Conservation Cooperative domain

Streamflow and basin-characteristic data are needed for a variety of scientific applications including estimation of flow in ungaged basins and hydro-ecological classification of rivers.   The U.S. Geological Survey (USGS), in cooperation with the Bureau of Reclamation and the Southern Rockies Landscape Conservation Cooperative (SRLCC), selected a subset of streamgages across the SRLCC domain that could be used for future modeling efforts.  The extent of the historical peak flow information is included for each streamgage, and a total of 139 basin characteristics were calculated for the drainage basin delineated at each streamgage.   Spatial features (streamgages, drainage basins) and their related attributes are contained within a geodatabase (SRLCC_Hydro.gdb).  The geographic extent of the database covers the entirety of hydrologic region 14, and parts of hydrologic regions 10, 11, 13, 15, 16, and 17.

Bathymetric change analyses of the southernmost portion of the Mokelumne River, California, from 1934 to 2018

Bathymetric change grids covering the periods of time from 1934 to 2011, from 2011 to 2018, and from 1934 to 2018 are presented. The grids cover a portion of the Mokelumne River, California, starting at its terminus at the San Joaquin River and moving upriver to the confluences of the north and south branches of the Mokelumne. Positive grid values indicate accretion, or a shallowing of the surface bathymetric surface, and negative grid values indicate erosion, or a deepening of the bathymetric surface.   Bathymetry data sources include the U.S. Geological Survey, California Department of Water Resources, and NOAAs National Ocean Service.

Mesocarnivore Survey of Crater Lake National Park, Klamath Network, 2016

Remote camera stations were set up in Crater Lake National Park from June to October 2016 to document occurrence of mesocarnivores and other wildlife. 124 cameras were set up at 31 primary sampling units (clusters of 4 cameras) throughout the park. Random locations for primary sampling units were chosen using a 3-km sampling grid over the park area. The dataset contains all species observed within the study time-frame, the date and time of observation and the number of individuals detected, as well as identification for individual locations, cameras and images. Of the three target species of conservation concern (Pacific fisher (Pekania pennanti), Pacific marten (Martes caurina), Sierra Nevada red fox (Vulpes vulpes necator)), only Pacific martens were detected.

Airborne electromagnetic and magnetic survey, southwestern San Joaquin Valley near Lost Hills, California, 2016: Inverted resistivity models

Airborne electromagnetic (AEM) and magnetic survey data were collected during October 2016 along 1,443 line kilometers in the southwestern San Joaquin Valley near Lost Hills, California. These data were collected in support of groundwater salinity mapping and hydrogeologic framework development as part of the U.S. Geological Survey California Oil, Gas, and Groundwater program and the California State Water Resources Control Board’s Program of Regional Monitoring of Water Quality in Areas of Oil and Gas Production. 
Deterministic laterally constrained inversions of the processed airborne electromagnetic data (https://www.sciencebase.gov/catalog/item/5d60373ae4b01d82ce9854ec) were developed using the AarhusINV code (Auken et al. 2014, https://doi.org/10.1071/EG13097) implemented in Aarhus Workbench software (v. 5.6.3.0, Aarhus Geosoftware, Aarhus, Denmark). Inversion parameters were selected by running a series of test models with varying starting model resistivity values, layer discretization, horizontal/lateral constraints, and other inversion parameters. A smooth 30-layer fixed-depth inversion model was developed with layer top depths ranging between 3 and 400 meters and layer thickness increasing with depth (see model data for exact thicknesses). Relatively weak vertical and lateral constraints on resistivity were used with values of 2.5 and 2.0, respectively. A 30 ohm-meter homogenous half-space starting model was used.  Sensor altitude was treated as a free parameter after the 5th iteration. The final model parameters described above were selected because they best represented the physical understanding of the system and minimized data misfit.  
The data provided include laterally-constrained inverted resistivity models and plotted depth sections along all flight lines.  Digital data are described in the data dictionary, additional details regarding data inversion are described in the metadata processing steps
