Historical methyl mercury in San Francisco Bay

San Francisco Bay, California is considered a mercury-impaired watershed.  Elevated concentrations of mercury are found in water and sediment as well as fish and estuarine birds.  Sources of mercury to the watershed since 1845 include sediment-associated mercury from mercury mining, mercury losses from gold amalgamation activities in mines of the Sierra Nevada, aerial deposition of mercury from global and regional emissions to air, and the direct discharge of mercury to Bay waters associated with the urbanization and industrialization of the estuary.  We assessed historical trends in mercury bioaccumulation by measuring mercury concentrations in feathers of the endangered California Ridgway’s rail (formerly California Clapper Rail) using museum specimens.  We developed a structural equation model to attribute variation in historical mercury bioaccumulation in rails to sources of mercury, and estimated the toxicological consequences of extreme mercury exposure to rails from known correlations between feather and blood mercury concentrations.

Island of Hawaii bird, mosquito, and avian malaria infection data 2001-2004

This data publication contains data files collected as part of a field, laboratory, and modeling effort aimed at uncovering ecological drivers of avian malaria transmission and impacts on Hawaiian honeycreepers across an elevational gradient on the eastern flank of Mauna Loa and Kilauea volcanoes on Hawaii Island. From 2001-2004, mosquito and bird data were collected at nine sites ranging 25 to 1,800 m above sea level. This data publication includes site and sampling coordinate data, mosquito capture data, mosquito avian malaria infection data, and point-transect distance sampling data. Site coordinate data consists of GPS spatial location data of sampling points where mosquitoes were captured and birds were surveyed to estimate abundance, comprising 45 points per site at 100 m intervals along five transects spaced 200 m apart. Mosquito capture data consists of counts of mosquitoes captured per trap night during 4-9 trapping nights per site per month over the study period. Mosquito infection data comprises avian malaria diagnostic data for a subset of captured mosquitoes that were dissected and malaria infection determined by microscopic examination of mosquito midguts and salivary glands. Point-transect distance sampling data consists of quarterly bird survey data in which observers recorded the horizontal distance of each sampling point to birds detected by sight and sound during 8-minute counts.

Available Water Capacity for the Upper Colorado River Basin in Maurer et al. (2002) Climate Data resolution (awc_UCRB_Maurer_resolution.asc)

awc_UCRB_Maurer_resolution.asc is an Esri ASCII grid representing the available water capacity 
(AWC) for the Upper Colorado River Basin.  AWC is the amount of water that a soil can hold, and 
is between a soil’s field capacity and the wilting point. In Soil-Water Balance model recharge 
simulations, AWC is multiplied by root zone depth to define the maximum water capacity of a cell, 
and any soil-moisture exceeding this amount is converted to recharge.

Flood Inundation Maps and Water Surface Elevation Data for the February 17, 2020 flood of the Pearl River at Jackson, Mississippi

The U.S. Geological Survey (USGS) documented the extent of flooding along a reach of the Pearl River through the metropolitan area of Jackson, Mississippi following the flood event of February 10-26, 2020.   The event was a result of heavy precipitation over a 72-hour period combined with pre-existing saturated soil conditions in the upper portions of the Pearl River basin.  USGS streamgages 02482000 Pearl River at Edinburg, MS and 02482550 Pearl River at Carthage, MS recorded 8.2 and 8.6 inches of precipitation respectively for the period of February 10-13.  On February 17, the Pearl River crested at USGS streamgage 02486000 Pearl River at Jackson, MS at 36.67 feet (270.06 ft North American Vertical Datum of 1988) which was the highest peak since 1983 and fourth highest peak since record began in 1901.  The USGS recovered and surveyed 72 high-watermarks along a 19-mile valley reach of the Pearl River in the Jackson area.  This reach extended from the Ross Barnett Reservoir dam downstream to the city of Byram.  These high-watermarks represent headwater flooding along the Pearl River main stem and backwater flooding along multiple tributaries.  Peak elevations were also recorded at seven tributary hydrograph stations within the study reach.  The high-watermark elevations were used to develop maps depicting the areal extent and depths of the flood.  A water surface profile of this event was also compared to profiles documented following the April 1979 and May 1983 flood events.  The file types contained in this data release include shapefiles, rasters, graphic (jpg), comma-separated values (csv) files, and metadata.

L5_1985_GOM_Fractional_Land_FAV_SAV_Water

These data were used to quantify land area change in a wetlands possible zone of coastal wetlands during a 1985-2020 observation period.  The datasets presented in this data release represent annual median estimates of the fractional amount of land, floating aquatic vegetation, submerged aquatic vegetation, and water per Landsat pixel.  These data are intended for coarse-scale analysis of wetland change area. The datasets are summarized by 10-digit Hydrologic Unit Code (HUC10), and land area change through time is fit using a penalized regression smooth spline. The trends are therefore generalized in time and are intended to present coarse scale observations of trends in wetland area change.

Coastwide Reference Monitoring System (CRMS) 2005, 2008, 2012, 2015, 2018, and 2021 Site 0677 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 six land-water products (2005, 2008, 2012, 2015, 2018, and 2021).  The resulting matrix has 64 possible classes defined by the combination of land and water categories on those six dates.

Seismic Reflection, Geometrics multi-channel streamer tracklines, USGS field activity 2017-003-FA, Mississippi River Delta front offshore of southeastern Louisiana (Esri polyline shapefile, GCS WGS 84)

High resolution bathymetric, sea-floor backscatter, and seismic-reflection data were collected offshore of southeastern Louisiana aboard the research vessel Point Sur on May 19-26, 2017, in an effort to characterize mudflow hazards on the Mississippi River Delta front. As the initial field program of a research cooperative between the U.S. Geological Survey, the Bureau of Ocean Energy Management, and other Federal and academic partners, the primary objective of this cruise was to assess the suitability of sea-floor mapping and shallow subsurface imaging tools in the challenging environmental conditions found across delta fronts (for example, variably distributed water column stratification and widespread biogenic gas in the shallow subsurface). Approximately 675 kilometers (km) of multibeam bathymetry and backscatter data, 420 km of towed chirp data, and 550 km of multichannel seismic data were collected. Varied mudflow (gully, lobe), prodelta morphologies, and structural features were imaged in selected survey areas from Pass a Loutre to Southwest Pass.

Chemical and isotopic composition of gas, water, and solids from the 2019-2020 water lake in Halema’uma’u Crater, Kīlauea Volcano, Hawaii: Gas Chemistry

This release contains data collected during two uncrewed aircraft systems (UAS) flights to sample gas plume compositions within Halema’uma’u crater, Kīlauea Volcano, Hawai'i.  Gas compositions were measured on October 26, 2019 with a multi-GAS (multiple Gas Analyzer System) instrumented DJI M600 Pro multi-rotor UAS.  The first flight targeted emissions from deep within the crater and the UAS flew as much as 510 m below its crater-rim launch point (1161 m elevation).  The second flight focused on sampling emissions from gas vents in the northern crater wall.
The multi-GAS payload included sensors to measure water vapor, carbon dioxide (CO2), and sample pressure (PP Systems SBA-5), sulfur dioxide (SO2; City Technology, Ltd. T3ST/F), hydrogen sulfide (H2S; City Technology, Ltd. T3H), a GPS unit (Garmin GPS 18x), and a datalogger (Campbell Scientific CR300-WIFI). The responses of the CO2, SO2, and H2S sensors were checked at the crater rim after the flights using portable gas standards (CO2 = 1000 ppm ± 2%, SO2 = 10 ppm ± 10%, H2S = 10 ppm ± 10%). The CO2 response was within -1% of the standard gas value and the baseline-corrected SO2 and H2S responses were accurate within 2% and 4%, respectively, when an ideal gas pressure correction was applied to the sulfur sensors' output.  Based on the sensor verification results, the accuracy of the CO2, SO2, and H2S measurements were limited by the accuracy of the gas standards.

Bat occupancy model predictions for Montana from acoustic and mist net data 2008-2010

The spread of white-nose syndrome (WNS) across the eastern United States has raised conservation concerns and provided motivation for efforts to monitor the impacts of this disease. Currently, WNS has not yet been detected in Montana, or any other western state besides Washington, and it is unknown how severe it will impact species in this region once it arrives. Within an occupancy model framework, we analyzed mist netting and acoustic records for eight bat species in Montana to estimate baseline distributions across the state prior to the arrival of WNS. Heterogeneity in the probabilities of occupancy for each species was explained with covariates for forest cover (%), elevation, ruggedness, and average degree days. Our analysis provided no evidence of spatial correlation among occupancy probabilities within each species, but did suggest spatial correlation among detection probabilities likely related to timing of surveys. We incorporated spatially-correlated random effects in the model for detection probabilities to account for these patterns.

DS926 Digital surfaces and thicknesses of selected hydrogeologic units of the Floridan aquifer system in Florida and parts of Georgia, Alabama, and South Carolina -- Polygon region depicting the weathered limestone residuum of the Floridan aquifer system

Digital surfaces and thicknesses of selected hydrogeologic units of the Floridan aquifer 
system were developed to define an updated hydrogeologic framework as part of the U.S. 
Geological Survey Groundwater Resources Program. This feature class contains the 
polygon region of the weathered limestone residuum overlying the FAS. It was developed 
on the basis of lithologic descriptions and from geologic maps showing the limestone 
outcrop areas. Residuum may not be present across the entire area of the polygon, 
especially in stream valleys where it may be eroded.

Bifenthrin Concentration, Percent Organic Matter, and Toxic Units, for Stream Sites Collected as Part of the Midwest Stream Quality Assessment

Direct and indirect ecological effects of the widely used insecticide bifenthrin on stream ecosystems are largely unknown. To investigate such effects, a manipulative experiment was conducted in stream mesocosms that were colonized by aquatic insect communities and exposed to bifenthrin-contaminated sediment; implications for natural streams were interpreted through comparison of mesocosm results to a survey of 100 Midwestern streams, USA. In the mesocosm experiment, direct effects of bifenthrin exposure included reduced larval macroinvertebrate abundance, richness, and biomass at concentrations (EC50s ranged 197.6 – 233.5 ng bifenthrin/ g organic carbon) previously thought safe for aquatic life. Indirect effects included a trophic cascade in which periphyton abundance increased after macroinvertebrate scrapers decreased. Adult emergence dynamics and corresponding terrestrial subsidies were altered at all bifenthrin concentrations tested. Extrapolating these results to the Midwestern stream assessment suggests pervasive ecological effects, with altered emergence dynamics likely in 40% of streams and a trophic cascade in 7% of streams. This study provides new evidence that a common pyrethroid might alter aquatic and terrestrial ecosystem function at the regional scale.

UMRS Floodplain Inundation Model - Open River Reach - South - Section 2

Floodplain inundation is believed to be the dominant physical driver of an array of ecosystem patterns and processes in the Upper Mississippi River System (UMRS). Here, we present the relative elevation of a slope-detrended floodplain terrain surface and river mile location used to map surface water depths derived from gaging locations along UMRS, as described in Van Appledorn et al. (2021; doi: 10.1002/rra.3628). We excluded areas permanently wetted (aquatic areas), surfaces in agricultural production, roads, and developed areas. The data are intended for use in geospatial analyses of UMRS floodplain ecosystem patterns and processes.
