Ratings and estimated provisional streamflow for streamgages in Virginia, water years 1991 through 2013

The U.S. Geological Survey, in cooperation with the Virginia Department of Environmental Quality, has quantified several measures of rating stability and the frequency and magnitude of changes to ratings through time for 174 real-time continuous streamgages active in Virginia as of September 30, 2013. Alternative flow (AltFlow) tables were developed as a method of estimating provisional flow data. They were constructed for periods with complete records of shifts and ratings between October 1, 1990 and September 30, 2013. Alternate flows consist of Qsame, the flow value from the shifted rating table used to compute the daily flow value at the time of the most recent flow measurement that corresponds to the gage height of each day’s daily flow value, and Qprev, the flow value from the shifted rating table in effect at the time of the previous flow measurement that corresponds to the gage height of each day’s daily flow value. A report (Messinger and Burgholzer, 2017) discusses several metrics that summarize AltFlow tables were computed and evaluated; particular importance was given to how well the metrics agreed with the descriptive stability class developed from interviews with hydrographers. Of these stability metrics, at least four were determined to be meaningful and to represent different aspects of control stability that might be relevant to water managers. These AltFlow tables were limited in several important ways that are discussed in the report; most important among them are that they were not developed from the ratings that were in place at the time provisional data were initially published to the web. 
This data release is comprised of the AltFlow tables and the expanded, shifted ratings used to develop them. Data are grouped by major river basin, and are provided in five Microsoft Excel files. These files include the formulas used to compute the AltFlow tables. These files may be used to extend the AltFlow record for Virginia past the end of the study period, or develop an AltFlow record for another state, using procedures described in Appendix 2 of the companion report (Messinger and Burgholzer, 2017).

Bathymetry--Drakes Bay and Vicinity, California

This part of DS 781 presents data for the bathymetry map of Drakes Bay and Vicinity map area, California. The raster data file for the bathymetry map is included in "Bathymetry_DrakesBay.zip," which is accessible from https://pubs.usgs.gov/ds/781/DrakesBay/data_catalog_DrakesBay.html. These data accompany the pamphlet and map sheets of Watt, J.T., Dartnell, P., Golden, N.E., Greene, H.G., Erdey, M.D., Cochrane, G.R., Johnson, S.Y., Hartwell, S.R., Kvitek, R.G., Manson, M.W., Endris, C.A., Dieter, B.E., Sliter, R.W., Krigsman, L.M., Lowe, E.N., and Chin, J.L. (J.T. Watt and S.A. Cochran, eds.), 2015, California State Waters Map Series—Drakes Bay and Vicinity, California: U.S. Geological Survey Open-File Report 2015–1041, pamphlet 36 p., 10 sheets, scale 1:24,000, https://doi.org/10.3133/ofr20151041.
The bathymetry map of Drakes Bay and Vicinity map area, California, was generated from bathymetry data collected by California State University, Monterey Bay (CSUMB), and by Fugro Pelagos. Mapping was completed between 2007 and 2010, using a combination of 200-kHz and 400-kHz Reson 7125, and 244-kHz Reson 8101 multibeam echosounders, as well as 468-kHz SEA SWATHPlus interferometric system. These mapping missions combined to collect bathymetry from about the 10-m isobath to beyond the 3-nautical-mile limit of California's State Waters. NOTE: the horizontal datum of the bathymetry data (NAD83) differs from the horizontal datum of other layers in this data series (WGS84). Some bathymetry grids within this map were projected horizontally from WGS84 to NAD83 using Esri tools to be more consistent with the vertical reference of the North American Vertical Datum of 1988 (NAVD88). These data are not intended for navigational purposes.

Biophysical assessment for indemnity selection of federal lands in Colorado: Soil salinity using electrical conductance

The “Biophysical assessment for indemnity selection of federal lands in Colorado: Soil salinity using electrical conductance” dataset includes information on soil salinity for 89 Indemnity Units, comprising 339 parcels of federal lands. These lands, currently managed by the Bureau of Land Management (BLM), are under consideration for transfer of ownership to the State of Colorado in compensation for federal lands not available for transfer at the time of statehood. The Indemnity Units total 23,130 acres of surface and mineral estate and 6,150 acres of mineral estate only. The specific land parcels to be transferred to the State will be finalized after an environmental analysis is completed, as required by the National Environmental Policy Act (NEPA).
This dataset summarizes information extracted from the Natural Resources Conservation Service (NRCS) gridded surface soils geographic database (gSSURGO). Fields retained and presented here include map unit (MU) codes and component (COMP) codes that may be used to reference records in the original NRCS data. Soil salinity is typically measured and evaluated based on electrical conductance (EC), and values presented here include the representative value for the map unit component (ECR) and the highest estimated value (ECH).
Soils with high salinity can affect the composition of vegetation and can limit production of plants through effects on leaf water potential and water use efficiency. Elevated salinity is often created by geologic and soil moisture relations that promote movement of salts. Salt levels can increase as a result of cropping, irrigation and land management. Salinity is typically measured using electrical conductance in wet soils; soils with electrical conductance less than 2 millimhos (mmhos)/centimeter (cm) are non-saline, 2 to less than 4 mmhos/cm are very slightly saline, 4 to less than 8 mmhos/cm are slightly saline, 8 to less than 16 mmhos/cm are moderately saline, and greater than or equal to 16 mmhos/cm are strongly saline. Millimhos/centimeter is the traditional unit for soil EC measurement; it is equivalent to the accepted scientific unit, decisiemens/meter (dS/m). Only two Indemnity Unit had soils with electrical conductance greater than 8 mmhos/cm. NRCS SSURGO documentation should be consulted for details regarding soil mapping and estimation and application of EC (https://www.nrcs.usda.gov/wps/portal/nrcs/detail/soils/home/?cid=nrcs142p2_053631).
Review of information regarding EC and salinity from the source (NRCS) is suggested: https://www.nrcs.usda.gov/wps/portal/nrcs/detail/national/home/?cid=nrcs144p2_065177 and/or https://www.nrcs.usda.gov/Internet/FSE_DOCUMENTS/nrcs142p2_053280.pdf.

Bottom dissolved oxygen measurements from Lake Erie's Central Basin, 2021

This data set, compiled by the USGS Lake Erie Biological Station, provides near-bottom measurements of temperature and dissolved oxygen for the Central Basin of Lake Erie. Data were recorded by self-contained environmental data loggers (PME, Inc., MiniDOT data loggers). The data loggers were deployed to collect data during mid-May 2021 through late October 2021 to better understand how hypoxia develops and influences fish habitat quality during lake stratification. The data loggers were deployed on acoustic telemetry receivers in a network designed to record tagged fish movements (Great Lakes Acoustic Telemetry Observation System, GLATOS). Additional years of data collection are planned, and data release will be updated as necessary.

Estimates of herbicide use for the sixty-first through the eightieth most-use herbicides in the conterminous United States

This coverage contains estimates of herbicide use for the sixty-first
through the eightieth most-used herbicides in the conterminous United
States as reported in Gianessi and Puffer (1991). Herbicide-use estimates
in this coverage are reported for each county polygon as acres treated,
pounds of active ingredient used, and pounds used per square mile.
The herbicide-use estimates provided by Gianessi and Puffer (1991) list
acres treated and pounds of active ingredient applied for a given crop
in each county for which use has been estimated. Cropping data are from the
1987 Census of Agriculture, and are subject to occasional suppressions of
acreage estimates at the county level due to problems of confidentiality
and census disclosure rules. The herbicide-use estimates included in
this coverage are totals of use on all crops treated in a given county.
The polygons representing county boundaries in the conterminous United
States, as well as lakes, estuaries, and other nonland-area features
were derived from the Digital Line Graph (DLG) files representing the
1:2,000,000-scale map in the National Atlas of the United States (1970).

Monitoring Hawaiian Biodiversity: Pilot study to assess changes to Hawaii Island forest birds and their habitat - 1977 bird dataset

The Hawaii Forest Bird Survey (HFBS) systematically characterized plant and bird communities across transects spanning all major Hawaiian Islands except O‘ahu. This extensive dataset has now been organized into a database and associated geographic information system (GIS) layers. This baseline provides an opportunity to assess how forest ecosystems and their constituent bird and plant populations have changed over time. As part of the HaBiTATS (Hawaiian Biodiversity Trends Across Time and Space) project, a select area on Hawai‘i Island was surveyed in 2015 with the objective of demonstrating the potential of using the HFBS methodology to reassess the status of bird and plant communities across multiple geographic regions and islands. The results of the comparative study presented herein highlight examples of the apparent vulnerability and resiliency of native-dominated Hawaiian ecosystems. Specific study objectives were to: (1) collect information on plant and bird species community composition, abundance, and spatial distribution following the original HFBS methodology; (2) assess changes in several biodiversity metrics; (3) examine changes in the distribution of invasive non-native species as well as changes in land use as potential drivers of native biodiversity patterns, and (4) demonstrate field and data analysis methods that may be applied to a large-scale biodiversity monitoring program. This is the bird dataset from 1977.

Early Estimates of Exotic Annual Grass (EAG) in the Sagebrush Biome, USA, 2024 (ver. 8.0, June 2024)

These datasets provide early estimates of 2024 fractional cover for exotic annual grass (EAG) species and one native perennial grass species on a weekly basis from April to late June. Typically, the EAG estimates are publicly released within 7-13 days of the latest satellite observation used for that version. Each weekly release contains five fractional cover maps along with their corresponding confidence maps for: 1) a group of 16 species of EAGs, 2) cheatgrass (Bromus tectorum); 3) Field Brome (Bromus arvensis); 4) medusahead (Taeniatherum caput-medusae); and 5) Sandberg bluegrass (Poa secunda). These datasets were generated leveraging field observations from Bureau of Land Management (BLM) Assessment, Inventory, and Monitoring (AIM) data plots; Harmonized Landsat and Sentinel-2 (HLS) based Normalized Difference Vegetation Index (NDVI); other relevant environmental, vegetation, remotely sensed, and geophysical drivers; and artificial intelligence/machine learning techniques. A total of 38,242 AIM plots from years 2016–2023 were used to train an ensemble of five-fold regression-tree models using a cross-validation approach (each observation was used as test data once and as training data four times) that developed all the fractional cover maps. The geographic coverage includes arid and semi-arid rangelands in the western U.S classified as shrubs or grassland/herbaceous by the 2021 National Land Cover Database at or below 2350-m elevation.

Tracklines of a multibeam survey of the Hudson Shelf Valley carried out in 1998 (polyline shapefile, geographic, WGS 84)

The Hudson Shelf Valley is the submerged seaward extension of the ancestral Hudson River drainage system and is the largest physiographic feature on the Middle Atlantic continental shelf. The valley begins offshore of New York and New Jersey at about 30-meter (m) water depth, runs southerly and then southeasterly across the Continental Shelf, and terminates on the outer shelf at about 85-m water depth landward of the head of the Hudson Canyon. Portions of the 150-kilometer-long valley were surveyed in 1996, 1998, and 2000 using a Simrad EM1000 multibeam echosounder mounted on the Canadian Coast Guard ship Frederick G. Creed. The purpose of the multibeam echosounder surveys was to map the bathymetry and backscatter intensity of the sea floor of the valley, providing a framework for geologic, oceanographic, and geochemical studies. The data from the three surveys are combined to produce grids of bathymetry and backscatter intensity at 12-m resolution that cover the entire valley and the head of the Hudson Canyon. The mapping was done by the U.S. Geological Survey in cooperation with the U.S. Army Corps of Engineers with support from the Canadian Hydrographic Service and the University of New Brunswick.

Coastwide Reference Monitoring System (CRMS) 2018 Site 0355 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 2018 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. Four previous assessments have been conducted (2005, 2008, 2012, and 2015/2016). Once the program creates enough data points for statistical analyses, these data will be used for land area change rate calculation.

Streamflow Permanence Probability rasters (PROSPER), 2004-2016, (ver. 2.0, February 2019)

Streamflow Permanence Probability (SPP) rasters represent the raw streamflow permanence probabilities produced by the PRObability of Streamflow PERmanence (PROSPER) model, annually for years 2004 through 2016, and overall mean and standard deviation.  The PROSPER model is a GIS raster-based empirical model of probabilistic predictions of a stream channel having year-round flow for any unregulated and minimally-impaired stream channel in the Pacific Northwest region, U.S. The model provides predictions of annual streamflow permanence probabilities at a 30-m spatial resolution based on monthly or annually updated values of climatic conditions and static physiographic variables associated with the upstream basin. Predictions correspond to pixels on the channel network consistent with the medium resolution National Hydrography Dataset channel network stream grid.
