This dynamic data release presents an aquatic reflectance product with 20-meter spatial resolution derived from Sentinel-2 satellite imagery for the conterminous United States using the Atmospheric Correction for OLI “lite” (ACOLITE). Aquatic reflectance, noted Rhow in ACOLITE documentation, is defined here as unitless water-leaving radiance reflectance and represents the ratio of water-leaving radiance (units of watts per square meter per steradian per nanometer) to downwelling irradiance (units of watts per square meter per nanometer) multiplied by π. This is also known as remote sensing reflectance (units of per steradian) multiplied by π. These data are intended for use in remote sensing of water color and differ...

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...

From May 27 to June 21, 2024, a Virginia Tech team of 5 sampled the fish community in 30 streams spanning a gradient of the developed landscape, including Potomac River, Rappahannock River, and upper Chesapeake Bay tributaries of Maryland, Washington, D.C., and Virginia, USA. These fish surveys were part of a larger stream-health study including other teams who surveyed geomorphology, water quality, flow, temperature, and macroinvertebrates at the same 30 streams. Upstream drainage area of these 30 streams ranged from approximately 7 to 32 sq. km, and width from 2 to 10 m. At each stream, we sampled fish from two reaches using two-pass backpack electrofishing and seining. Reach A was the main reach surveyed by all...

In cooperation with the Georgia Department of Transportation, the U.S. Geological Survey (USGS) has prepared geospatial layers representing the locations of USGS streamgages, other weather monitoring locations, and upstream drainage basins of streamgages in the State of Georgia. 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.

The geochemical data included here were generated as part of the Earth Mapping Resources Initiative (Earth MRI), which was developed by the U.S. Geological Survey (USGS) in response to a Federal directive calling on various Federal agencies to address potential vulnerabilities in the Nation’s supply of critical mineral resources. Earth MRI is a partnership between the USGS, State Geological Surveys, and industry coordinating with other federal agencies to accomplish the mission. The primary purpose of this initiative is to identify potentially mineralized areas containing critical minerals by gathering new basic geologic data about the United States and its territories and to make these data publicly available through...

This data release contains multiple data layers and describes the processing steps associated with the U.S. Geological Survey Professional Paper 1900 "Prospectivity Mapping for Geologic Hydrogen". 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...

Stable isotopes of water preserved in geologic archives, primarily as oxygen (d18O), have proven critical for documenting Earth’s climatic and hydrologic systems past and present. 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. Annual tree-ring cellulose d18O from Picea engelmannii growing...

Landslides hazards pose a serious threat to people and infrastructure in the Federated States of Micronesia (FSM). To develop a comprehensive understanding of the landslides hazards in FSM, the USGS-USAID Landslide Disaster Assistance Team (LDAT) has put together landslide inventories for each state using satellite imagery. Mapping was done using RGB satellite imagery from Maxar, Planet Labs, and Google Earth. This inventory is for Kosrae state and covers all available imagery between January 2005 and October 2023. Landslides are dated by a window of occurrence based on the last images before and first image after the occurrence of the landslide. Each event was mapped using a point at the center of the headscarp...

The Maumee River network contributes a significant amount of total phosphorus (P), including both sediment-bound P (sed-P) and dissolved P, to the Western Lake Erie Basin. Most Maumee River headwater streams are agricultural, with conservation management focused on limiting sediment and nutrient transport from cropland to the stream network. However, several studies have shown streambank erosion to be another source of suspended sediment in these streams. This data release is comprised of six tables with data related to channel geometry, streambed sediment, and streambank erosion in the Little Flatrock Creek stream network in 2019. Data included provided for extrapolation from 15 described reaches to the entire...
