Salinas Valley Operational Model: Input Operational Data (ver. 2.0, September 2023)

This digital dataset contains the surface water operational data used for the Salinas Valley Operational Model (SVOM) including the time series data and the operational rules. While much of the input data is shared between the Salinas Valley Operational Model (SVOM) and the Salinas Valley Integrated Hydrologic Model (SVIHM), the SVOM has additional input data specific to the purpose and function of the model. 
The SVOM is a hypothetical baseline model developed to examine the benefit of different reservoir operations to the availability of water resources for the San Antonio and Nacimiento Reservoirs. The San Antonio and Nacimiento reservoirs are used for regional water supply and management of Salinas River flows to support conservation, fish passage, and support downstream diversions for the Salinas Valley Watershed Model (SVWM). By using the SVOM, Monterey County can evaluate reservoir management projects and practices to help make decisions that optimize the use of available groundwater resources and develop habitat conservation plans to sustain threatened salmon populations. To improve flood protection and increase storage capacity, Monterey County is considering a 11,000-foot gravity-flow interlake tunnel connecting the Nacimiento and San Antonio reservoirs. The tunnel would allow the excess water from winter storm events to be captured and transferred into the San Antonio Reservoir, increasing storage capacity by 18%. The interlake tunnel would also require the spillway elevation to be raised as the San Antonio Reservoir dam to accommodate the additional water. The SVOM will be used to evaluate the feasibility and benefits of different tunnel and operation configurations in support of environmental and engineering design needs. While this data release includes some of the files necessary to set up the interlake tunnel scenario, the SVOM does not include the implementation or analysis for the interlake tunnel. The reservoir releases are dynamically simulated based on the defined operational rules, instead of a time series of historical releases like in SVIHM, using the surface water operations framework from MODFLOW-OHWM (Hanson and others, 2014; Boyce and others, 2020). The operation rules are based on current reservoir operation rules and legal constraints, allowing for the reservoir’s release into the stream network to be simulated internally to account for changes in reservoir storage and reservoir releases for conservation, demands, and flood management. Each rule is a set of logic statements that determine if reservoir releases are triggered. The time series data and supporting datasets included are required to carry out the logic in each of the rules.

Data associated with Sofaer and Jarnevich 'Accounting for sampling patterns reverses the relative importance of trade and climate for the global sharing of exotic plants'

These data were analyzed for the publication 'Accounting for sampling patterns reverses the relative importance of trade and climate for the global sharing of exotic plants': 
Aim: Exotic species’ distributions reflect patterns of human-mediated dispersal, species’ climatic tolerances, and a suite of other biotic and abiotic factors. The relative importance of each of these factors will shape how the spread of exotic species is affected by ongoing economic globalization and climate change. However, patterns of trade may be correlated with variation in scientific sampling effort globally, potentially confounding studies that do not account for sampling patterns.
Location: Global.
Methods: We used data from the Global Biodiversity Information Facility (GBIF) to summarize the number of plant species with exotic occurrences in the U.S. that also occur in each other country worldwide. We assessed the relative importance of trade and climatic similarity for explaining variation in the number of shared species while evaluating several methods to account for variation in sampling effort among countries. 
Results: Accounting for variation in sampling effort reversed the relative importance of trade and climate for explaining numbers of shared species. Trade was strongly correlated with numbers of shared U.S. exotic plants between the U.S. and other countries before, but not after, accounting for sampling variation among countries. Conversely, accounting for sampling effort strengthened the relationship between climatic similarity and species sharing. Using the number of records as a measure of sampling effort provided a straightforward approach for analyzing occurrence data, whereas species richness estimators and rarefaction were less effective at removing sampling bias.
Main conclusions: Our work provides support for broad-scale climatic limitation on exotic species distributions, illustrates the need to account for variation in sampling effort in large biodiversity databases, and highlights the difficulty in inferring causal links between the economic drivers of invasion and global exotic species occurrence patterns.

Text files of the Real-time Kinematic (RTK) navigation logged with HYPACK Software during USGS Cruise 07011 conducted off the southern shore of Martha's Vineyard, 2007

The USGS Woods Hole Science Center conducted a nearshore geophysical survey offshore of the southern coast of Martha's Vineyard, in the vicinity of the Martha's Vineyard Coastal Observatory (MVCO) in August 2007.  This mapping program was part of a larger research effort supporting the Office of Naval Research (ONR) Ripples Directed-Research Initiative (DRI) studies at MVCO by providing data collection and modeling.  The geophysical data will be used to provide initial conditions for wave and circulation models for the study area.  Ultimately, geophysical mapping, oceanographic measurements and modeling will help to improve our understanding of coastal sediment-transport processes.
The geophysical mapping utilized a suite of high-resolution instrumentation to map the surficial sediment distribution, depth and sub-surface geology: dual-frequency 100/500 KHz sidescan-sonar system, 234-KHz interferometric sonar, and 500 Hz -12 KHz chirp sub-bottom profiler. The survey was conducted aboard the M/V Megan Miller August 9-13, 2007. The study area covers 35 square kilometers from about 0.2 km to 5-km offshore of the south shore of Martha's Vineyard, and ranges in depth from ~ 5 to 20 meters.

Predictions of specific conductance and departures from background specific conductance in the Chesapeake Bay watershed, 1999-2016

Freshwater salinization is an emerging water quality issue for non-tidal streams and rivers in the Chesapeake Bay watershed (CBW), USA region. A model was developed to predict specific conductance (SC; a proxy for salinity) conditions across the CBW and departures from background SC. Discrete observations of SC from 1999-2016 were acquired from a published SC data inventory and explanatory variables describing sources of SC were compiled from several sources. Random forests modeling was conducted to predict SC at four time periods (1999-2001, 2004-2006, 2009-2011, and 2014-2016) at all non-tidal National Hydrography Dataset Plus Version 2.1 (NHDPlusV2.1; 1:100K scale) stream reaches. These predictions were then compared to a national background SC dataset to determine relative departures from background SC for each NHDPlusV2.1 reach ID. This data release contains model input data, model output data, and predictions of SC. 
This data release contains the following three files:
1."Model_input.csv": Contains SC observations, explanatory variables, and additional columns relevant to the model application. 
2. "Model_output.csv": Contains predicted SC values for the reaches contained in either the testing or training datasets, as well as the feature contributions for each explanatory variable. 
3. "Model_predictions.csv": Contains predicted SC, predicted/expected (or P/E) ratios, and departure categories for all non-tidal reach IDs in the CBW for the four time periods.

F307NC_video_observations

This part of DS 781 presents video observations from cruise F307NC in northern California The vector data file is included in "f307nc_video_observations.zip," which is accessible from https://pubs.usgs.gov/ds/781/video_observations/data_catalog_video_observations.html. 
Between 2006 and 2007, the seafloor in northern California was mapped by California State University, Monterey Bay, Seafloor Mapping Lab (CSUMB) and by the U.S. Geological Survey (USGS), using both multibeam echosounders and bathymetric sidescan sonar units. These mapping missions combined to collect bathymetry and acoustic-backscatter data from about the 10-m isobath to out beyond the 3-nautical-mile limit of California's State Waters. To validate the interpretations of sonar data in order to turn it into geologically and biologically useful information, the USGS ground-truth surveyed the data by towing camera sleds over specific locations throughout the region. During the 2007 ground-truth cruise, the camera sled housed two video cameras (one forward looking and the other vertical looking), a high-definition video camera, and an 8-megapixel digital still camera. The video was fed in real time to the research vessel, where USGS and NOAA scientists recorded both the geologic and biologic character of the seafloor into programmable keypads once every minute. In addition to recording the seafloor characteristics, a digital still photograph was captured once every 30 seconds. This ArcGIS shape file includes the position of the camera, the time each observation was started, and the visual observations of geologic and biologic habitat.

BITH2014_TurkeyCreekUnit_EAARLB_BE_z15_n88g12A_mosaic_metadata: EAARL-B Topography-Big Thicket National Preserve: Turkey Creek Unit, Texas, 2014

A bare-earth topography digital elevation model (DEM) mosaic for the Turkey Creek Unit of Big Thicket National Preserve in Texas, was produced from remotely sensed, geographically referenced elevation measurements collected on January 19, 21, 22, 25, 26, and 29, 2014 by the U.S. Geological Survey, in cooperation with the National Park Service - Gulf Coast Network. Elevation measurements were collected over the area using the second-generation Experimental Advanced Airborne Research Lidar (EAARL-B), a pulsed laser ranging system mounted onboard an aircraft to measure ground elevation, vegetation canopy, and coastal topography. The system uses high-frequency laser beams directed at the Earth's surface through an opening in the bottom of the aircraft's fuselage. The laser system records the time difference between emission of the laser beam and the reception of the reflected laser signal in the aircraft. The plane travels over the target area at approximately 55 meters per second at an elevation of approximately 300 meters, resulting in a laser swath of approximately 240 meters with an average point spacing of 0.5-1.6 meters. A peak sampling rate of 15-30 kilohertz results in an extremely dense spatial elevation dataset. More than 100 kilometers of coastline can be surveyed easily within a 3- to 4-hour mission. When resultant elevation maps for an area are analyzed, they provide a useful tool to make management decisions regarding land development.

Conceptual marsh units of salt marshes on the Eastern Shore of Virginia

This data release contains coastal wetland synthesis products for the Atlantic-facing Eastern Shore of Virginia (the data release for the Chesapeake Bay-facing portion of the Eastern Shore of Virginia is found here: https://doi.org/10.5066/P997EJYB). Metrics for resiliency, including unvegetated to vegetated ratio (UVVR), marsh elevation, and tidal range are calculated for smaller units delineated from a digital elevation model, providing the spatial variability of physical factors that influence wetland health. The U.S. Geological Survey has been expanding national assessment of coastal change hazards and forecast products to coastal wetlands with the intent of providing federal, state, and local managers with tools to estimate the vulnerability and ecosystem service potential of these wetlands. For this purpose, the response and resilience of coastal wetlands to physical factors need to be assessed in terms of the ensuing change to their vulnerability and ecosystem services.

Digital data sets that describe aquifer characteristics of the Rush Springs aquifer in western Oklahoma

This data set consists of digitized polygons of constant
recharge values for the Rush Springs aquifer in western
Oklahoma. This area encompasses all or part of Blaine, Caddo,
Canadian, Comanche, Custer, Dewey, Grady, Stephens, and
Washita Counties. For the purposes of modeling the
ground-water flow in the Rush Springs aquifer, Mark F. Becker
(U.S. Geological Survey, written commun., 1997) defined the
Rush Springs aquifer to include the Rush Springs Formation,
alluvial and terrace deposits along major streams, and parts
of the Marlow Formations, particularly in the eastern part of
the aquifer boundary area.
The Permian-age Rush Springs Formation consists of highly
cross-bedded sandstone with some interbedded dolomite and
gypsum. The Rush Springs Formation is overlain by
Quaternary-age alluvial and terrace deposits that consist of
unconsolidated clay, silt, sand, and gravel. The Rush Springs
Formation is underlain by the Permian-age Marlow Formation
that consists of interbedded sandstones, siltstones,
mudstones, gypsum-anhydrite, and dolomite beds (Mark F.
Becker, written commun., 1997). The parts of the Marlow
Formation that have high permeability and porosity are where
the Marlow Formation is included as part of the Rush Springs
aquifer.
The Rush Springs aquifer underlies about 2,400 square miles of
western Oklahoma and is an important source of water for
irrigation, livestock, industrial, municipal, and domestic
use. Irrigation wells are reported to have well yields greater
than 1,000 gallons per minute (Mark F. Becker, written
commun., 1997).
Mark F. Becker created some of the recharge data set by
digitizing parts of previously published surficial geology
maps. There are 87 recharge rates, ranging from 0.09 to 3.20
inches per year, used by Mark F. Becker (written commun.,
1997) to simulate the ground-water flow in the Rush Springs
aquifer. The average estimated recharge is about 2 inches per
year or about 7 percent of the average annual
precipitation. The recharge rates were based on stream
discharge measured at sites in drainage basins in the Rush
Springs study area during low-flow periods in March 1989 and
February 1991 (Mark F. Becker, written commun., 1997).
Ground-water flow models are numerical representations that
simplify and aggregate natural systems. Models are not unique;
different combinations of aquifer characteristics may produce
similar results. Therefore, values of recharge used in the
model and presented in this data set are not precise, but are
within a reasonable range when compared to independently
collected data.

Coastwide Reference Monitoring System (CRMS) 2005, 2008, 2012, and 2015 Site 0610 Land-Water Matrix

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 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 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.
