Data were collected by the River Studies Program, Texas Parks and Wildlife Department. River Studies is an interdisciplinary river and stream assessment program. Its primary goal is to assure sufficient quantity and quality of water to maintain the natural biodiversity of aquatic ecosystems and their associated wetlands and riparian lands. The program staff works to characterize aquatic ecosystems, evaluate impacts to those systems, and determine water quantity and quality needs to address policy and regulatory issues. Results from long-term projects provide data from large geographic areas to address broad-scale policy and regulatory issues. Aquatic biological samples (fish, mussels, and benthic macroinvertebrates)...

Metadata specific to this state's data is not available. The MARIS Master metadata record can be accessed to help provide general data descriptions and guidance to users. MARIS is an internet-based information sharing network that allows multiple states to provide a common set of variables via a single web interface. MARIS is not a “dataset” but rather links specific content of multiple states’ datasets. MARIS does not capture all of the information from a state’s aquatic dataset – only a subset of data collected as part of aquatic species sampling surveys. The MARIS structure was developed by a consortium of state fish and wildlife agencies and implemented through contracts with various universities. In the past,...

While wildlife species do not respect political boundaries, conservation planning and implementation is often restricted by them. Thus, regionally rare species can be placed in the unenviable position of not being prioritized by any jurisdiction that they inhabit due to competition for scarce conservation resources. A regional conservation framework will enable states to cooperate toward common goals and share the costs and accomplishments of regionally conserving at risk species. However, the development of a regional conservation framework is inhibited by patchy species occurrence data. These data gaps can be informed by species distribution models. This project will compile available mussel data, develop species...

The Coastal Storm Modeling System (CoSMoS) makes detailed predictions (meter-scale) over large geographic scales (100s of kilometers) of storm-induced coastal flooding and erosion for both current conditions and future SLR scenarios, and in many locations, there are additional products for long-term shoreline change, cliff retreat, and groundwater hazards.  Resulting projections for future climate scenarios (sea-level rise and storms) provide emergency responders and coastal planners with critical storm-hazards information that can be used to increase public safety and mitigate physical damages to reduce risk, and more effectively manage and allocate resources to increase resilience in response to a changing climate...

Maryland Department of Natural Resources, Information Technology Service and Inland Fisheries Service developed a data management system referred to as the Geographic Inland Fisheries Survey system (GIFS). The GIFS database contains all parameters typical of fisheries information including date, location, fish species, invertebrate species, habitat, water quality, and tournament details. The information is often oriented to sport fish surveys though not exclusively.

This data represents fish samples collected by Fisheries and Water Resource staff of the Wisconsin Department of Natural Resources between 1945 to 2014. Only electrofishing data were included in this dataset. Data include both community index sampling and targeted gamefish data from lakes, large rivers and wadeable streams. Data were restructured to meet MARIS standards. MARIS is an internet-based information sharing network that allows multiple states to provide a common set of variables via a single web interface.

This data release provides digital flight line data for a high-resolution radiometric survey over the South Pass-Granite Mountains region in central Wyoming. The airborne survey was funded by the state of Wyoming, designed by the Wyoming State Geological Survey (WSGS), and contracted by the USGS. The survey is aligned with the Earth Mapping Resources Initiative and was designed to meet complementary needs related to geologic mapping and characterization of mineral resource potential. A total of 47,973.8 line km of radiometric data were acquired over an area of 8639 km2. Data were collected from a helicopter flown at a nominal terrain clearance of 100 meters (m) above topography along N-S flight lines spaced at 200...

Duck banding data is integral to the Adaptive Harvest Management (AHM) process that uses both band recovery data and aerial breeding population survey data to establish hunting regulatory packages each year. Mallard banding in Alaska is one component of the process to set hunting regulations for ducks in the Pacific Flyway by providing harvest rate estimates for the Western Mallard AHM model (U.S. Fish and Wildlife Service 2021). Harvest rate is used in coordination with breeding population size estimates from the Waterfowl Breeding Population and Habitat Survey to determine the optimal regulatory strategy (liberal, moderate, restrictive, or closed) for dabbling ducks in the Pacific Flyway. Each regulatory alternative...

Landforms along the Pacific, Gulf of Mexico, and Atlantic coastlines for the conterminous United States are attributed with the relative vulnerability of horizontal erosion due to sea-level rise to characterize coastal zone stability. The position and extent of landforms are geospatially indexed as line-events where these coastal zone features are intersected by the linear-referenced 2013 - 2014 U.S. Geological Survey National Hydrography Dataset Coastline, which corresponds to the National Oceanic and Atmospheric Administration (NOAA) 2013 - 2014 mean high water level datum delineated in intertidal zones open to oceans, behind barrier coasts in bays, lagoons, and estuaries, and sometimes where tidal currents reach...

This data release includes data processing scripts, data products, and associated metadata for a study investigating trends in Mississippi River (MR) nitrogen and phosphorus loads to the Gulf of Mexico. This data release consists of three main components: 1) Nitrogen and phosphorus balances, which account for major nutrient inputs (fertilizer, manure, waste water treatment facility effluent, atmospheric deposition, weathering and nitrogen fixation) and outputs (crop harvest and removal and gaseous emissions of nitrogen). Annual balances are estimated for the Mississippi River Basin, which covers 2,887,854 square kilometers for the time period 1950 to 2017, 2) Weighted Regression on Time Season and Discharge (WRTDS)...
