The Geochemical Atlas of Alaska, 2016 - WBD Means

A rich legacy of geochemical data produced since the early 1960s covers the great expanse of Alaska; careful treatment of such data may provide significant and revealing geochemical maps that may be used for landscape geochemistry, mineral resource exploration, and geoenvironmental investigations over large areas. To maximize the spatial density and extent of data coverage for statewide mapping of element distributions, we compiled and integrated analyses of more than 175,000 sediment and soil samples from three major, separate sources: the U.S. Geological Survey, the National Uranium Resource Evaluation program, and the Alaska Division of Geological &amp; Geophysical Surveys geochemical databases. Various types of heterogeneity and deficiencies in these data presented major challenges to our development of coherently integrated datasets for modeling and mapping of element distributions. Researchers from many different organizations and disparate scientific studies collected samples that were analyzed using highly variable methods throughout a time period of more than 50 years, during which many changes in analytical techniques were developed and applied. Despite these challenges, the U.S. Geological Survey has produced a new systematically integrated compilation of sediment and soil geochemical data with an average sample site density of approximately 1 locality per 10 square kilometers (km2) for the entire State of Alaska, although density varies considerably among different areas. From that compilation, we have modeled and mapped the distributions of 68 elements, thus creating an updated geochemical atlas for the State.

SPARROW model dataset for total suspended solids in North Carolina, including simulated stream loads

To better understand the influence of human activities and natural processes on surface-water quality, the U.S. Geological Survey (USGS) developed the SPARROW (SPAtially Referenced Regressions On Watershed attributes) (Schwarz and others, 2006; Alexander and others, 2008) model. The framework is used to relate water-quality monitoring data to sources and watershed characteristics that affect the fate and transport of constituents to receiving surface-water bodies. The core of the model consists of using a nonlinear-regression equation to describe the non-conservative transport of contaminants from point and nonpoint sources on land to rivers, lakes and estuaries through the stream and river network. In North Carolina, excessive sediment loadings have contributed to the degradation of surface-water quality, and riverine and upland sediment sources are recognized as major contributors of this degradation in rivers, lakes and estuaries. The SPARROW model was configured for North Carolina to predict sediment loads in streams and to evaluate the relative importance of sediment sources and other landscape characteristics. The model time period is 1999 to 2014 and centered at 2012. This data release includes model input (data1_vTSS.zip), model predictions (predict_TSS.zip) that represent simulated stream load, model catchment shapefile (model_catchments.zip), and a brief methodology (Methodology_TSS.pdf). See the 'Methodology_TSS.pdf' file for model documentation.

Coastwide Reference Monitoring System (CRMS) 2021 Site 0006 land-water classification data

Wetland restoration efforts conducted by the Coastal Wetlands Planning, Protection and Restoration Act (CWPPRA) in Louisiana rely on monitoring efforts to determine the efficacy of these efforts. 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 398 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. A DOQQ is a raster image in which displacement in the image caused by sensor orientation and terrain relief has been removed and combines the image characteristics of a photo with geometric qualities of a map. The DOQQs generated for this project consist of 2021 Color Infrared (CIR) Digital Imagery. These images were classified into land and water categories using a threshold of the near infrared (NIR) band, followed by supervised and unsupervised classification.  Initial classification results are then reviewed by multiple image analysts to identify and manually recode errors. The final land-water classifications are intended to serve as both geographic and quantitative assessments of landscape composition on the date of acquisition. Five previous assessments have been conducted (2005, 2008, 2012, 2015/2016, and 2018). Once the program creates enough data points for statistical analyses, these data will be used for land area change rate calculation.

Acquisition and observation logs for seabed video and sediment samples from Stellwagen Bank during U.S. Geological Survey field activity 2014-066-FA, aboard the R/V Auk, November 10, 2014

This field activity is part of the effort to map geologic substrates of the Stellwagen Bank National Marine Sanctuary region off Boston, Massachusetts. The overall goal is to develop high-resolution (1:25,000) interpretive maps, based on multibeam sonar data and seabed sampling, showing surficial geology and seabed sediment dynamics. This cruise was conducted in collaboration with the Stellwagen Bank National Marine Sanctuary, and the data collected will aid research on the ecology of fish and invertebrate species that inhabit the region. The Sanctuary's research vessel, R/V Auk, visited 44 locations on Stellwagen Bank at which a customized Van Veen grab sampler (SEABOSS) equipped with a video camera and a CTD was deployed in drift mode to collect sediment for grain-size analysis, video imagery of the seabed, and measurements of water column properties.

SARS-CoV-2 Data from National Wastewater Surveillance System Surge Capacity Sampling, September 2021

Wastewater-based epidemiology (WBE) is used to determine the consumption of, or exposure to, chemicals or pathogens in human populations, and is conducted by collecting representative samples of untreated wastewater (influent) to quantify pathogens shed in the population served by the sampled wastewater system. 
The Centers for Disease Control and Prevention (CDC) and the US Department of Health and Human Services (HHS), in collaboration with the United States Geological Survey (USGS) and other agencies throughout the federal government, initiated the National Wastewater Surveillance System (NWSS) in response to the COVID-19 pandemic to conduct WBE using analytical methods for the collection and analysis of SARS-CoV-2 (severe acute respiratory syndrome coronavirus 2) in wastewater influent. The data generated by NWSS helps public health officials to better understand the extent of SARS-CoV-2 infections in communities. 
Surge capacity sampling to support NWSS and carried out by the USGS was conducted in September 2021 in six states (Colorado, Missouri, Utah, North Carolina, Ohio, and Wisconsin). 354 samples from 25 wastewater treatment plants (WWTP) representing 26 distinct service areas (one facility has two treatment areas) were analyzed using ddPCR (digital droplet polymerase chain reaction) for SARS-CoV-2 using standard CDC assays targeting N2- and E-genes plus the wastewater marker pepper mild mottle virus (PMMoV). Results for both genes are included in this data release (708 records).

Landbird survey bird and habitat data collected in Hawaii Volcanoes National Park during 2015 and 2016

Hawaiʻi Volcanoes National Park (HAVO) was surveyed for landbirds and landbird habitat from February through April 2015 and February through April 2016. This information provides the second datum in the time-series of Pacific Island Network (PACN) monitoring for long-term trends in landbird distribution, density, and abundance. Initial PACN surveys were conducted in 2010 and are repeated every five years. The entire survey area was comprised of eight tracts in forest, woodland, and shrub habitat, totaling 26,364 ha. Each tract was surveyed using point-transect distance sampling to calculate estimates of bird abundance and density. . In addition to the permanent PACN survey transects, randomly generated point-transects were also surveyed, allowing for a split panel sampling design.

2-m Bathymetric Grid of National Oceanic and Atmospheric Administration (NOAA) Survey H11922 in Rhode Island Sound West of Gay Head, Massachusetts (H11922_2M_GEO, Geographic, WGS84)

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. Bathymetry, originally collected by NOAA for charting purposes, provides a fundamental framework for research and management activities off southern New England, shows the composition and terrain of the seabed, and provides information on sediment transport and benthic habitat. During July-August 2008 NOAA completed hydrographic survey H11922 west of Gay Head, Massachusetts, in Rhode Island Sound and during July and September 2010 bottom photographs and surficial sediment data were acquired as part of ground-truth reconnaissance surveys of this area. Interpretations were derived from the multibeam echo-sounder data and the ground-truth data used to verify them. For more information on the ground-truth surveys see http://quashnet.er.usgs.gov/data/2010/10033/ and http://quashnet.er.usgs.gov/data/2010/10005/

Compilation of BLM Monitoring Reports Assessing Post Wildfire Seeding of Rangelands, 2001-2009

Post-fire rehabilitation seeding in the U.S. Intermountain West, primarily conducted by the Bureau of Land Management, is designed to reduce the risk of erosion and weed invasion while increasing desirable plant cover. Seeding effectiveness is typically monitored for three years following treatment, after which a closeout report is prepared. We evaluated 220 third-year closeout reports describing 214 aerial and 113 drill seedings implemented after wildfires from 2001 through 2006. Each treatment was assigned a qualitative success rating of good, fair, poor, or failure based on information in the reports. Seeding success varied by both treatment (aerial or drill) and year. Aerial seedings were rated 13.6% good, 18.3% fair, 29.6% poor, and 38.5% failure. Drill seedings were rated as 30.1% good, 24.8% fair, 23.0% poor, and 22.1% failure. Logistic regression analysis found that aerial seedings were more successful with increasing elevation, long-term average precipitation, and precipitation received in the first and third years following treatment. Drill seeding success was best explained by elevation only, suggesting that these treatments are less sensitive to long-term average and precipitation received after treatment than aerial seedings. We found monitoring reports did not report seeding success consistently using quantiative objectives, control areas to proived adequate comparisons, and did not provide maps, making them difficult to assess spatially. Providing additional information in monitoring reports about important factors that can influence seeding success such as pre-fire vegetation would be useful for the creation of a decision analysis tool to aid land managers who are confronted with whether or not to perform post-fire rehabilitation treatments given limited resources and budgets.
