The Barrier Island Comprehensive Monitoring (BICM) program was developed by Louisiana’s Coastal Protection and Restoration Authority (CPRA) and is implemented as a component of the System Wide Assessment and Monitoring Program (SWAMP). The program uses both historical data and contemporary data collections to assess and monitor changes in the aerial and subaqueous extent of islands...

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...

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...

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.

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...

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...

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...

The ~21 m deep Mammoth Site (MS) bone bed site at Hot Springs, South Dakota, provides a unique opportunity to reconstruct paleoenvironmental conditions on the northern Great Plains of the United States. Past published radiocarbon analyses of mammoth bones found within the MS sinkhole suggested they were deposited ~23-42 ka. However, two U-series ages ranging between 129-150 ka and a

This report and accompanying maps and database address the geologic and geophysical character of a block of ten 7.5’ quadrangles that span the San Gorgonio Pass region. The study culminates more than four decades of intermittent geologic and geophysical mapping investigations by the U.S. Geological Survey (USGS). Published results from these investigations fall into two categories: (1)...

Laminated soil carbonate rinds are a Quaternary paleoclimate archive whose isotope composition is linked to soil formation conditions. At Rio Mesa, Utah (USA), we investigated the fidelity of rind records in a river terrace setting by determining the seasonal timing of rind formation and testing for inter-record replication. We infer soil carbonate formed in the spring season...
