Coastwide Reference Monitoring System (CRMS) 2005, 2008, 2012, 2015, 2018, and 2021 Site 0562 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.

Pesticides in Small Volume Plasma Samples

Pesticides are widely applied and can enter the environment, potentially effecting non-target organisms. To better evaluate pesticide exposure using non-lethal techniques, a method was developed for the extraction of  pesticides and their degradates from small (100 µL) volume plasma samples. Solid phase extraction was used for lipid removal after plasma samples were protein precipitated. Samples were analyzed with liquid chromatography and gas chromatography with tandem mass spectrometry. Samples were spiked at three different concentrations, low (25 ng/mL), medium (100 ng/mL), and high (250 ng/mL) and recoveries of 70 to 130% were achieved across all spike levels for  179, 180, and 183 of 210 target compounds were achieved, respectively; 182 compounds had recoveries of 70 to 130% across all spike levels and method detection levels ranged from 0.4 to 13.0 ng/mL These results can aid in characterizing pesticide exposure in nontarget organisms.

Amphibian (chorus frog, wood frog, tiger salamander) surveys in Rocky Mountain National Park (1986-2022)

This data release contains information collected during surveys for chorus fogs (Pseudacris maculata), wood frogs (Lithobates sylvaticus) and tiger salamanders (Ambystoma mavortium ) conducted in Rocky Mountain National Park (1986 – 2022) by the U.S. Geological Survey. Survey methods included visual encounter and aural surveys, and dip netting. Data collected between 1986 and 1994 focused on named water bodies in Rocky Mountain National Park. Data collected between 1995 and 1999 are from focal monitoring sites as well as sporadic surveys of other wetlands. Data collected between 2000-2002 represent repeated surveys conducted between 1986 and 1994 (e.g., park-wide surveys of named water bodies) and additional surveys of unnamed waterbodies. Data collected after 2002 were collected under an occupancy framework. Sites were identified within pre-defined catchments using the National Wetlands Inventory Database to locate potential amphibian breeding habitat (e.g., ponds, ephemeral wetlands). If appropriate sites were encountered in the field and were not indicated on National Wetland Inventory databases (https://www.fws.gov/program/national-wetlands-inventory/metadata), they were added as incidental sites. Waterbodies were visited and surveyed at least two times during the amphibian active season (May and mid-August). Water bodies were surveyed for all life stages of amphibians.

Inundation Exposure Assessment for Select Islands in the Republic of the Marshall Islands

As a low-lying island nation, the Republic of the Marshall Islands (RMI) is at the forefront of exposure to climate change impacts, including, primarily, inundation (coastal flooding).  Increased water levels can stem from episodic events (storm surge, wave run-up, king tides) or from chronic conditions (long term sea-level rise).  Land elevation is the primary geophysical variable that determines exposure to inundation in coastal settings.  Accordingly, accurate coastal elevation data are a critical input for assessments of inundation exposure and vulnerability.  Previous research has demonstrated that the quality of data used for elevation-based assessments must be well understood and applied to properly model potential impacts.  The vertical uncertainty of the input elevation data controls to a large extent the increments of water level increase and planning horizons that can be effectively used in an assessment.  Recent high-resolution elevation data along the coast, such as the digital elevation models (DEMs) used here, exhibit high vertical accuracy, and thus have become indispensable for inundation exposure assessments.  When properly characterized, the vertical accuracy of the high-resolution, high-accuracy elevation data can be used to generate maps and report assessment results with the uncertainty stated in terms of a specific confidence level, which is the approach employed here.  This data release includes the results of a quantitative assessment of inundation exposure for five selected sites in RMI (Aur Island and Tobal Island in Aur Atoll, Ebon Island in Ebon Atoll, Likiep Island in Likiep Atoll, and Mejit Island), including rigorous accounting for the vertical uncertainty in the input elevation model data.  Areas subject to marine inundation (direct hydrologic connection to the ocean) and low-lying land (no direct hydrologic flowpath to the ocean) were mapped and characterized for different inundation levels.

Location of Sea-Floor Photographs Acquired During U.S. Geological Survey (USGS) Cruise 2013-005-FA in Block Island Sound (Geographic, WGS 84, 2013-005_298BOTPHOTOS)

The U.S. Geological Survey (USGS), in cooperation with the National Oceanic and Atmospheric Administration (NOAA), is producing detailed geologic maps of the coastal sea floor. Bathymetric and sidescan-sonar data, originally collected by NOAA for charting purposes, provide a framework for research and management activities along western Block Island Sound, show the composition and terrain of the seabed, and provide information on sediment transport and benthic habitat. During June 2013, bottom photographs and surficial sediment data were acquired as part of a ground-truth reconnaissance survey of this area. Interpretations were derived from the multibeam-echosounder, sidescan-sonar, sedimentary, and photographic data collected in Block Island Sound. For more information on the ground-truth survey see https://cmgds.marine.usgs.gov/fan_info.php?fan=2013-005-FA.

Repeat microgravity data from Phoenix, Arizona, 2020-2023

This dataset represents the network-adjusted results of relative- and absolute-gravity surveys performed from 2020 to 2023 in and near the city of Phoenix, Arizona. Relative surveys were done using a Zero Length Spring, Inc. Burris relative-gravity meter. Absolute-gravity surveys were done using a Micro-g LaCoste, Inc. A-10 absolute-gravity meter. The effect of solid Earth tides and ocean loading were removed from the data prior to network adjustment. Non-linear instrument drift was removed by evaluating gravity change during repeated measurements at one or more base stations. Vertical gradients between the relative- and absolute-gravity meters were measured at each station where both types of measurement were collected to correlate the measurements of the two instruments. Vertical gradients were measured using a relative-gravity meter and tripod set to the height of the absolute-gravity meter. Relative-gravity differences and absolute-gravity data were combined using least-squares network adjustment, as implemented in the software GSadjust (https://code.usgs.gov/sgp/gsadjust). Data are provided for 105 stations collected over 4 discrete, annual surveys.

Supporting data for low-flow statistics computed for streamflow gages and methods for estimating selected low-flow statistics for ungaged stream locations in Ohio, water years 1975–2020

This data release comprises the tabular data used to develop regression equations for estimating selected low-flow statistics for ungaged streams in Ohio that are not substantially affected by regulation, diversions, or other anthropogenic influences, and the geographic information systems (GIS) layer to implement them in the U.S. Geological Survey StreamStats application (https://streamstats.usgs.gov).
A statewide recharge-based estimate of streamflow variability index (SVI) was used as an explanatory variable in developing many of the equations to estimate selected low-flow statistics at ungaged sites in Ohio and is included as part of this data release. Regressions, using SVI as the explanatory variable, were used to develop equations for predicting annual and seasonal minimum 1-, 7-, 30-, and 90-day mean flows with 10-year recurrence intervals, the harmonic mean flow, and the 80 percent duration flow. The resulting equations are presented in VonIns and Koltun (2024). To apply the equations to ungaged sites in Ohio, a raster (grid) of estimated streamflow variability index (SVI) for Ohio is included. The raster was developed using Environmental Systems Research Institute (ESRI) Spatial Analyst Software’s Empirical Bayesian kriging (EBK) geoprocessing function with at-gage computed SVIs used as the dependent variable and a recharge raster (grid) of estimated mean annual natural ground-water recharge (Wolock, 2003) as the explanatory variable. Other explanatory variables used to develop the equations and included in tabular form as part of this data release include decimal longitude and drainage area. A statewide coverage of decimal longitude and drainage area were not included as part of this data release because they are already available for ungaged streams within StreamStats.

Surface-sediment grain-size distributions of the Elwha River delta, Washington, August 2019

This portion of the data release presents sediment grain-size data from samples collected on the Elwha River delta, Washington, in August 2019 (USGS Field Activity 2019-633-FA). Surface sediment was collected from 77 locations using a small ponar, or 'grab', sampler from the R/V Frontier in water depths between about 1 and 17 m around the delta. An additional 30 samples were collected by hand at low tide. A hand-held global satellite navigation system (GNSS) receiver was used to determine the locations of sediment samples. The grain size distributions of suitable samples were determined using standard techniques developed by the USGS Pacific Coastal and Marine Science Center sediment lab. Grab samples that yielded less than 50 g of sediment were omitted from analysis. The grain-size data are provided in a comma-delimited spreadsheet (.csv).
