Estimated groundwater elevations and standard errors from the application of kriging to median groundwater elevation data from 2010 in the Mesilla/Conejos-Médanos Basin, United States and Mexico

These data include 217 median groundwater elevations computed from compiled measurements made in the year 2010 within the transboundary Mesilla/Conejos-Médanos Basin, United States and Mexico, along with their corresponding interpolated groundwater elevations and standard errors from the application of kriging. Of the 217 median groundwater elevation locations, 109 were in the United States and 108 were in Mexico. Considered measurements were limited to wells thought to be completed in the basin-fill/Santa Fe Group aquifer based on well records. This dataset includes a comma-separated values file (Control_points.csv) that provides the median groundwater elevations that were kriged to yield rasters of estimated groundwater elevations (Groundwater_elevations.tif) and interpolation uncertainty in terms of standard errors (Standard_errors.tif).

Waterfowl disturbance in California and Nevada (2018)

Long-term environmental management to prevent waterfowl population declines is informed by ecology, movement behavior and habitat use patterns. Extrinsic factors such as human-induced disturbance can cause behavioral changes which may influence movement, and resource needs, driving variation that affects management efficacy. To better understand the relationship between human-based disturbance and animal movement and habitat use, and their potential effects on management, we GPS tracked 15 dabbling ducks in California over about 4-weeks before, during and after the start of a recreational hunting season in October and November 2018. We recorded locations at 2-minute intervals across three separate 24-hour tracking phases: Phase 1) two weeks before the start of the hunting season (control (undisturbed) movement); Phase 2) the hunting season opening weekend; and Phase 3) a hunting weekend two weeks after opening weekend. We used GLMM models to analyze variation in movement and habitat use under hunting pressure compared with normal observed patterns prior to commencement of hunting. We also compared responses to differing levels of disturbance related to the time of day high - lethal); moderate - non-lethal (crepuscular); and low - night). During opening weekend flight (percent time and distance) more than doubled during moderate and low disturbance and increased by 50 percent during high disturbance compared with the pre-season weekend. Sanctuary use tripled during moderate and low disturbance and increased 50 percent during high disturbance. Two weeks later flight decreased in all disturbance levels but was only less than the pre-season levels during high disturbance. In contrast, sanctuary use only decreased at night while daytime doubled from 45 percent to greater than 80 percent, although not to pre-season levels. Birds adjust rapidly to disturbance and nocturnal foraging compensates energy deficits. These results have implications for energetics models that estimate population food requirements and management may benefit from reassessing the juxtaposition of habitat to optimize wetland management for waterfowl.

Data Release for "Cavity-nesting bee nesting success across gradients of floral resources and land-cover"

We measured nesting rates and nesting success for a community of cavity-nesting bees across gradients of floral abundance, floral richness, and land-cover in the Prairie Pothole Region. Variables in this dataset include a unique transect identifier, a count of the occupied nests per transect, total floral species richness per transect, total floral stem abundance per transect, bee species richness, number of emerged adult bees per transect, and the proportion of those emerged bees which were female. In addition, there are land-cover measurements of the total area, in hectares, of grasslands, wetlands, and woodlands within 500m and 1500m of each transect. We binned land-covers from the 2019 National Agricultural Statistics Service Cropland Data Layer into our definitions of grasslands (Other Hay/Non Alfalfa, Sod/Grass Seed, Fallow/Idle Cropland, and Grassland/Pasture), wetlands (Woody Wetlands and Herbaceous Wetlands), and woodlands (Deciduous Forest, Evergreen Forest, and Shrubland).

North American tree-ring fire-scar site descriptions

Fire size and severity continue to increase across large parts of North America, driven by a combination of climate change and effects of human land use. Instrumental records are too short to fully understand patterns, trends, and drivers of fire that are necessary to model future fire. Tree-ring fire scars provide centuries-long records of fire regimes, including fire frequency, season, size, and fire-climate relationships. We compiled fire-scar site descriptions from &gt; 100 researchers across the continent to produce the first North American tree-ring fire-scar network. These data provide descriptive information for all known tree-ring fire-scar sites in North America. Data fields include location, name, area and species sampled, years of the tree-ring fire-scar chronology, and references.

Cumulative thermal units and developmental stage of Pallid Sturgeon free embryos reared at multiple temperatures

This dataset documents the onset of developmental stages of pallid sturgeon free embryos from hatch through melanin plug expulsion, when reared in the laboratory at five nominal temperatures (14, 17, 20, 23, and 26 degrees Celsius, ° C).  Onset of developmental stages were recorded in days post-hatch (DPH) and cumulative thermal units (CTU).  CTU are calculated as the sum of water temperature, in ° C, during the time of exposure, in our case, from the time of hatch to the time of sample preservation.   
Pallid sturgeon transition through a series of brief developmental stages during a free-embryo period from hatch to melanin plug expulsion, which is regarded as the approximate onset of exogenous feeding. Detailed characteristics of 45 developmental stages were described by Dettlaff and others (1993) for Acipenser sturgeon from the time of egg deposition to melanin plug expulsion and the initiation of exogenous feeding.  Stages 1–35 describe egg and embryo development within the protective chorion, and stages 36–45 describe free embryos from hatch to the initiation of exogenous feeding.

Field measurements of water depth from the American River near Fair Oaks, CA, October 19-21, 2020

Field measurements of water depth were acquired from a reach of the American River at Sailor Bar, near Fair Oaks, California, October 19-21, 2020, to support research on remote sensing of water depth from satellite images. The depth measurements included in this data release were obtained via two different methods: 1) By wading the shallow channel margins with RTK GPS receivers and measuring water surface elevations along the water's edge and bed elevations within the channel; depths were calculated by subtracting bed elevations from the nearest water surface elevation. 2) For the deeper areas representing most of the channel, depths were recorded along a series of cross-sections by a SonTek RiverSurveyor S5 acoustic Doppler current profiler (ADCP) and a SonarMite single beam echo sounder deployed from a boat. The spatial location of each measurement was obtained via Trimble R10 RTK GPS receivers. The map projection and datum for these data are UTM Zone 10 N and WGS84, respectively. The ADCP- and echo sounder-based depth measurements were cross-calibrated to one another using collocated observations from the two instruments and then combined with the wading measurements for the purposes of this data release, which consists of a comma-delimited (*.csv) text file with three columns: Easting_m, Northing_m, and Depth_m; the units of the spatial coordinates and the depths are meters. This ground-based depth data set was used to calibrate (i.e., train) models for inferring water depths from passive optical image data and to assess the accuracy of image-derived depth estimates.

Field measurements of water depth from the Colorado River near Lees Ferry, AZ, March 16-18, 2021

Field measurements of water depth were acquired from a reach of the Colorado River near Lees Ferry, Arizona, March16-18, 2021, to support research on remote sensing of water depth from satellite images. The depth measurements included in this data release were obtained along a series of cross-sections using a SonTek RiverSurveyor M9 acoustic Doppler current profiler (ADCP) deployed from a boat. The spatial location of each measurement was obtained using a differential GPS included as part of the RiverSurveyor M9 ADCP instrument package. The map projection and datum for these data are UTM Zone 12S and WGS84, respectively. The USGS Qrev software program was used to ingest and process the raw ADCP data.  The Qrev data file was then imported into MATLAB, which was used to create a comma-delimited (*.csv) text file with three columns: Easting_m, Northing_m, and Depth_m; the units of the spatial coordinates and the depths are meters. This ground-based depth data set was used to calibrate (i.e., train) models for inferring water depths from passive optical image data and to assess the accuracy of image-derived depth estimates.

Oyster Bayou Marsh Creation and Terracing (CS-59): 2018 land-water classification

The Louisiana State Legislature created the Coastal Wetlands Planning, Protection and Restoration Act (CWPPRA) in order to conserve, restore, create and enhance Louisiana's coastal wetlands. The wetland restoration plans developed pursuant to these acts specifically require an evaluation of the effectiveness of each coastal wetlands restoration project in achieving long-term solutions to arresting coastal wetlands loss. This data set includes mosaicked aerial photographs for the Oyster Bayou Marsh Creation and Terracing (CS-59) project for 2018. This data is used as a basemap land-water classification. It also serves as a visual tool for project managers to help them identify any obvious problems or land loss within their project boundary. To better evaluate the effectiveness of restoration efforts, a land-water classification is performed on specific CWPPRA sites to help assess landscape changes.

Viral-like particles are associated with endosymbiont pathology in Florida corals affected by stony coral tissue loss disease

Stony coral tissue loss disease (SCTLD) was first documented in 2014 near the Port of Miami, Florida, and has since spread north and south along Florida’s Coral Reef, killing large numbers of more than 20 species of coral and leading to the functional extinction of at least one species, Dendrogyra cylindrus. SCTLD is assumed to be caused by bacteria based on presence of different molecular assemblages of bacteria in lesioned compared to apparently healthy tissues, its apparent spread among colonies, and cessation of spread of lesions in individual colonies treated with antibiotics. However, light microscopic examination of tissues of corals affected with SCTLD have not shown bacteria associated with tissue death. Rather, microscopy shows dead and dying coral cells and symbiotic dinoflagellates (endosymbionts) suggesting a breakdown of host cell and endosymbionts symbiosis. It is unclear whether host cells die first leading to death of endosymbionts or vice versa. Based on microscopy, hypotheses as to possible causes of SCTLD include infectious agents not visible at the light microscopy level or toxicosis, perhaps originating from endosymbionts. To clarify this, we examined corals affected with SCTLD and apparently healthy corals using transmission electron microscopy.  Endosymbionts in SCTLD-affected and apparently healthy corals consistently had varying degrees of pathology associated with elongated particles compatible in morphology with filamentous positive single-stranded RNA viruses of plants (anisometric viral-like particles-AVLP).  There was apparent progression from early to late replication of AVLP in the cytoplasm of endosymbionts adjacent to or at times within chloroplasts, with morphologic changes in chloroplasts consistent with those seen in plant cells infected by viruses.  Coral host cell pathology appeared limited to massive proliferation and lysis of mucus cells.  Based on these findings, we hypothesize that SCTLD is a viral disease of endosymbionts leading to coral host death. Efforts to confirm the presence of a virus associated with SCTLD through other means should be a priority. These include showing the presence of a virus through molecular assays such as deep sequencing, attempts to grow this virus in the laboratory through culture of endosymbionts, localization of virus in tissue sections using immunohistochemistry or in-situ hybridization, and experimental infection of known-virus-negative corals to replicate disease at the gross and microscopic level.

Beach topography of the Columbia River littoral cell, Washington and Oregon, 2021

This portion of the USGS data release presents topography data collected during surveys performed in the Columbia River littoral cell, Washington and Oregon, in 2021 (USGS Field Activity Number 2021-632-FA). Topographic profiles were collected by walking along survey lines with global navigation satellite system (GNSS) receivers mounted on backpacks. Prior to data collection, vertical distances between the GNSS antennas and the ground were measured using a tape measure. Hand-held data collectors were used to log raw data and display navigational information allowing surveyors to navigate survey lines spaced at 100- to 1000-m intervals along the beach. Profiles were surveyed from the landward edge of the study area (either the base of a bluff, engineering structure, or just landward of the primary dune) over the beach foreshore, to wading depth on the same series of transects as nearshore bathymetric surveys that were conducted during the same time period. Additional topographic data were collected between survey lines in some areas with an all-terrain vehicle (ATV) equipped with a GNSS receiver to constrain the elevations and alongshore extent of major morphological features. Positioning data from the survey platforms were referenced to a GNSS base station with known horizontal and vertical coordinates relative to the North American Datum of 1983. Differential corrections from the GNSS base stations to the survey platforms were either applied in real-time with a VHF radio link, or post-processed using Trimble Business Center software. Orthometric elevations relative to the NAVD88 vertical datum were computed using National Geodetic Survey Geoid12a offsets. The average estimated vertical uncertainty of the topographic measurements is 4 cm. The final point data are provided in comma-separated text format and are projected in Cartesian coordinates using the Washington State Plane South, meters coordinate system.
