Network Analysis of USGS Streamflow Gages Network Analysis of USGS Streamflow Gages
This data release has components of an analysis of the coverage, resolution, and representation of national public interests in streamflow information by the USGS streamflow gaging network that was active in water year 2020. The workflow for the analysis is implemented as scripts and functions in the statistical programming language R. The spatial framework for the analysis is based on...
USGS National and Global Oil and Gas Assessment Project - Western Australia Assessment Unit Boundaries and Assessment Input Forms USGS National and Global Oil and Gas Assessment Project - Western Australia Assessment Unit Boundaries and Assessment Input Forms
This data release contains the boundaries of conventional assessment units for the assessment of undiscovered oil and gas resources in Perth Basin, NW Shelf, Browse Basin, and Bonaparte Gulf Basin Provinces of Western Australia. The Assessment Unit is the fundamental unit used in the National Assessment Project for the assessment of undiscovered oil and gas resources. The Assessment Unit...

This data release contains the boundaries of conventional assessment units for the assessment of undiscovered oil and gas resources in the Greater Taranaki and East Coast Basins, New Zealand. The Assessment Unit is the fundamental unit used in the National Assessment Project for the assessment of undiscovered oil and gas resources. The Assessment Unit is defined within the context of the...
Continuous Water Level, Salinity, and Temperature Data from Coastal Wetland Monitoring Wells, Cape Cod, Massachusetts (ver. 3.0, September 2025) Continuous Water Level, Salinity, and Temperature Data from Coastal Wetland Monitoring Wells, Cape Cod, Massachusetts (ver. 3.0, September 2025)
Environmental parameters affecting plant productivity and microbial respiration, such as water level, salinity, and groundwater temperature included in these datasets, are key components of wetland carbon cycling, carbon storage, and capacity to maintain elevation. Data were collected to (1) provide background data to evaluate potential differences in water level and carbon flux between...
Static chamber gas fluxes and carbon and nitrogen isotope content of age-dated sediment cores from a Phragmites wetland in Sage Lot Pond, Massachusetts, 2013-2015 Static chamber gas fluxes and carbon and nitrogen isotope content of age-dated sediment cores from a Phragmites wetland in Sage Lot Pond, Massachusetts, 2013-2015
Coastal wetlands are major global carbon sinks, however, they are heterogeneous and dynamic ecosystems. To characterize spatial and temporal variability in a New England salt marsh, static chamber measurements of greenhouse gas (GHG) fluxes were compared among major plant-defined zones (high marsh dominated by Distichlis spicata and a zone of invasive Phragmites australis) during 2013...
Metal concentrations in seston and water in the Clark Fork River, MT Metal concentrations in seston and water in the Clark Fork River, MT
Legacy mine waste from the Clark Fork River in Western Montana has contributed 100 million tons of tailings into the watershed between 1880 and 1982 (E.D. Andrews, Longitudinal dispersion of metals in the Clark Fork River, Montana, Lewis Publishers, 1987). Tailings deposited along the floodplain, streambanks and river channel continue to contribute metal contaminated material into the...
