Location and phenology observations for beaked hazelnut (Corylus cornuta), Oregon grape (Mahonia aquifolium), and salal (Gaultheria shallon) in western North America

These data provide the locations and phenological dates of three shrub species: beaked hazelnut (Corylus cornuta), Oregon grape (Mahonia aquifolium), and salal (Gaultheria shallon), collected from various publicly available data sources including data from USFS Forest Inventory and Analysis program, USFS R-6 Ecology Program, US National Park Service, USDI Bureau of Land Management, USA National Ph

Hg Concentrations of Fish Tissue Samples in the Vicinity of Yellow Pine, Idaho

The USGS examined mercury (Hg) concentrations in fish populations inhabiting impacted and reference streams as part of an investigation into the transport of trace metals in a watershed impacted by legacy mercury mining downstream from the Cinnabar mine site, Valley County, ID. Fish were sampled through an electrofishing survey utilizing a two-pass quantitative depletion approach where possible. F

Aerial photographs from the Yampa and Little Snake Rivers in northwest Colorado used to characterize channel changes occurring between 1954 and 1961

Aerial photographs of the Yampa and Little Snake Rivers acquired in 1954 and 1961 were used to examine channel changes occurring along these two rivers during this time period. In addition, these data were used to develop and test a generalizable new approach to characterizing the uncertainty associated with analyses of channel change based on time series of remotely sensed data, which we term th

Evaporation at Reedy Lake, daily data, Orange County, Florida, November 28,2001 - December 16, 2019

The data consists of daily evaporation measurements/estimates for the time period November 28, 2001 to December 16, 2019. These data are derived from Bowen ratio energy budget computations of actual evaporation based on meteorological and water temperature data at the USGS Reedy Lake evaporation station (USGS station number 282458081364800). This station is located near the center of a lake within

Cumulative compaction (from site activation through 2022) of subsurface sediments in the Chicot and Evangeline aquifers in the greater Houston Area, Texas (ver. 5.0, August 2023)

The U.S. Geological Survey, in cooperation with the Harris?Galveston Subsidence District, City of Houston, and the Fort Bend Subsidence District, produced a dataset through 2018 of compaction values in the Chicot and Evangeline aquifers in the Houston-Galveston region, Texas. This dataset contains compaction values of subsurface sediments (mostly in the fine-grained silt and clay layers because li

Mean annual water-budget components for the Island of Maui, Hawaii, for a set of eight future climate and land-cover scenarios

These shapefiles represent the spatial distribution of mean annual water-budget components, in inches, for the Island of Maui, Hawaii for a set of eight future climate and land-cover scenarios. The future climate conditions used in the water-budget analyses were derived from two end-of-century downscaled climate projections including (1) a projected future climate condition representative of phase

EverForecast hydrologic output for April 2020: a six-month water stage forecast for the Greater Everglades

Operational ecological forecasting is an emerging field that leverages ecological models in a new, cross-disciplinary way, using a real-time or nearly real-time climate forecast to project near-term ecosystem states. These applications give decision-makers lead time to anticipate and manage state changes that degrade ecosystem functions or directly impact humans. The Everglades Forecasting model (

Velocity measurements around the sill bubble curtain in Peoria Lock on the Illinois River, Illinois, September 17-18, 2019

Bubble curtain systems, also called "bubblers," are used in navigation locks to prevent the buildup of ice around the gates in the winter. It has been proposed that bubblers could potentially serve an additional purpose as a deterrent to the upstream movement of aquatic invasive species through locks. An interagency study involving the U.S. Army Corps of Engineers, U.S. Fish and Wildlife Service,

A Global Hybrid Vs30 Map with a Topographic-Slope-Based Default and Regional Map Insets

Time-averaged shear wave velocity over the upper 30 meters of the earth's surface (Vs30) is a key parameter for estimating ground motion amplification as both a predictive and diagnostic tool for earthquake hazards. A first-order approximation of Vs30 is commonly obtained via a topographic slope-based or terrain proxy due to the widely available nature of digital elevation models. However, better-

Nanoscale Molecular Composition of Solid Bitumen from the Eagle Ford Group Across a Natural Thermal Maturity Gradient

Solid bitumen is a petrographically-defined secondary organic matter residue produced during petroleum generation and subsequent oil transformation. The presence of solid bitumen impacts many shale reservoir properties including porosity, permeability, and hydrocarbon generation and storage, amongst others. Furthermore, solid bitumen reflectance is an important parameter for assessing the thermal

Preliminary global database of known and inferred gas hydrate locations

For more than 25 years, the U.S. Geological Survey Gas Hydrates Project has compiled and maintained an internal database of locations where the existence of gas hydrate has been confirmed or inferred in research studies. The existence of gas hydrate was considered confirmed when gas hydrate was recovered by researchers or videotaped from a vehicle (such as a submersible or remotely operated vehicl

Jonathan Davis Wetland Restoration (BA-20): 2018 land-water classification

The Louisiana State Legislature created the Coastal Wetlands Planning, Protection and Restoration Act (CWPPRA) in order to conserve, restore, create and enhance Louisiana's coastal wetlands. The wetland restoration plans developed pursuant to these acts specifically require an evaluation of the effectiveness of each coastal wetlands restoration project in achieving long-term solutions to arresting
