Low pH Exposure Alters Mediator Dependent Response in Poly(o-phenylenediamine) Based Molecularly Imprinted Polymer – Electrochemical Sensors (MIP-ES) Low pH Exposure Alters Mediator Dependent Response in Poly(o-phenylenediamine) Based Molecularly Imprinted Polymer – Electrochemical Sensors (MIP-ES)
Molecularly imprinted polymer-electrochemical sensors are a promising approach for detecting non-electrochemically active contaminants such as per- and polyfluoroalkyl substances. However, exposure of poly(ortho-phenylenediamine) based molecularly imprinted polymer films to strongly acidic conditions can alter the polymer environment and complicate interpretation of electron mediator...
Low-flow metrics and explanatory variable data for 107 basins in Massachusetts, 1943-2022 Low-flow metrics and explanatory variable data for 107 basins in Massachusetts, 1943-2022
The U.S. Geological Survey, in cooperation with the Massachusetts Department of Conservation and Recreation, evaluated potential drivers of low streamflows in Massachusetts by use of statistical models with selected low-flow metrics as the dependent variables. Low-flow metrics were computed in six ways: the 2nd and 10th percentile of daily flows during a climate year, these same...
Low-Frequency Radar and Inferred Ice Thickness, Gulkana Glacier, Alaska, 2024 Low-Frequency Radar and Inferred Ice Thickness, Gulkana Glacier, Alaska, 2024
This dataset contains ice thickness interpretations made from a radar survey conducted on Gulkana Glacier as part of the USGS Benchmark Glacier Monitoring Program on April 19th and 20th, 2024. The dataset contains a CSV file with the complete set of radar interpretations from the Spring 2024 Gulkana field campaign. The data includes a total of 36,378 observations. Radar interpretations...
Lower Cook Inlet Fish and Invertebrate Community Composition, Distribution, and Density Lower Cook Inlet Fish and Invertebrate Community Composition, Distribution, and Density
This data package includes seven tables with data about the composition, distribution, relative abundance, seasonal availability, energy density, morphometrics, taxonomy, and stable isotope values of benthic fish and invertebrates, as well as oceanographic data within the proposed oil and gas lease sale area in lower Cook Inlet, Alaska.
Luminescence Data Collected for San Juan River Sediment Geochemical Studies 2023-2024 Luminescence Data Collected for San Juan River Sediment Geochemical Studies 2023-2024
This Data Release summarizes the dating results from sedimentary deposits sampled by the USGS Geologic Hazards Team and analyzed at the USGS Luminescence Geochronology Laboratory. During field seasons 2023 and 2024, these samples were collected as part of the Abandoned Mine Lands Task of the Intermountain West Geologic Framework project, in collaboration with the Navajo Nation and USGS...
Luminescence Data For Floodplain Carbon Storage: Soil Organic Carbon, Surface Age, and Vegetation in an Icy River Corridor Luminescence Data For Floodplain Carbon Storage: Soil Organic Carbon, Surface Age, and Vegetation in an Icy River Corridor
Rivers are some of the most dynamic features of the Arctic landscape, yet their role in the global carbon cycle is poorly understood. Researchers are still unraveling the intricacies of how river dynamics control organic carbon (OC) accumulation, transport, and degradation in riverine systems. The interplay between permafrost thermal state in river corridors, snow and ice-affected...
Luminescence Data for the Geomorphological Evolution of the Provincetown Hook, Cape Cod, Massachusetts Luminescence Data for the Geomorphological Evolution of the Provincetown Hook, Cape Cod, Massachusetts
These Holocene aged samples are from three sediment cores obtained near the Provincetown Hook spit in Cape Cod, Massachusetts. The goal of the geochronology work is to determine when shoreface sediments, which represent the oceanward extent of the spit, were present at the surface for the Provincetown Hook. Results from this work support efforts to publish more recent sedimentological...
