Heuristically-determined geospatial boundary of streams and rivers draining to the Gulf of Mexico in the south-central and southeastern United States, July 2018 Human alteration of waterways has impacted the minimum and maximum streamflow in more than 86% of monitored streams nationally and may be the primary cause for ecological impairment in river and stream ecosystems. Restoration of freshwater inflows can positively affect shellfish, fisheries, habitat, and water quality in streams, rivers, and estuaries. Increasingly, state and local decision makers and Federal agencies are turning their attention to the restoration of flows as part of a holistic approach to restoring water quality and habitat and protecting and replenishing living coastal and marine resources and the livelihoods that depend on them. In 2017, the U.S. Geological Survey (USGS) Lower Mississippi-Gulf...

Monitoring environmental conditions for potential drought risk is challenging in such a dispersed Island nation, and current drought hazard products provide generalities regarding conditions on a broad geographic scale. A team of USGS scientists and managers of natural resources and natural hazards in the RMI used IMERG (Integrated Multi-satellitE Retrievals for GPM) satellite estimates of precipitation to develop content and a template for timely monthly reporting...

The focus of regional moment tensor analysis is to estimate the moment magnitude, faulting parameters and source depth of earthquakes that are too small to be recorded teleseismically. Thus they have the potential of extending the earthquake catalog to magnitudes less than about M4-4.5. This data distribution provides the details required to critically review the resulting catalog, e.g., the waveforms used, processing parameters and velocity model. In addition the issue of the correct local magnitude...

These surveys and assessments describe the bathymetry, water-quality conditions, and on-site field crew observations and impressions for each water body and its surrounding catchment area. Data collected may assist BOT with resource management decisions and practices, as well as contribute to an inventory that can be shared with other local governmental agencies.

These layers also include streamgages in nearby states which directly measure waters within Georgia. The streamgages have attributes describing their location, elevation, parameters measured, peak flow information, flood frequency region percentage, land cover characteristics, and distance to nearest other streamgage.

However, timescale differences of water isotope inputs to proxy systems and the signal embedded in long paleorecords often confound translation to observed hydroclimatic metrics. Here, a unique 20-year dataset of meteorology, hydrology, and the isotopic composition of weekly meteoric and surface water samples (d18O, d2H) are combined with paleoclimate d18O data from tree-ring cellulose and lake carbonate to better understand proxy signals of Upper Colorado river basin drought.

The data comprise the geologic and geophysical inputs used in support of the U.S. Geological Survey's efforts to create the first map of geologic hydrogen prospectivity within the U.S. The maps are based on our understanding of the geologic hydrogen system model, which includes three primary components: 1) a source of natural hydrogen, 2) a reservoir to store hydrogen in the subsurface, and 3) a competent seal to retain the hydrogen and prevent leakage to the Earth’s surface. Collectively, the data release includes 44...

This inventory is a result of a rapid response mapping effort led by the U.S. Geological Survey’s Landslide Assessments, Situational Awareness, and Event Response Research (LASER) project. LASER collaborated with state surveys and landslide researchers to identify landslides and their impacts for situational awareness and emergency response.
