The U.S. Geological Survey, in cooperation with the U.S. Environmental Protection Agency's Long Island Sound Study (https://longislandsoundstudy.net), characterized nitrogen export from forested watersheds and whether nitrogen loading has been increasing or decreasing to help inform Long Island Sound management strategies. The Weighted Regressions on Time, Discharge, and Season (WRTDS...

Volcanic mass flows, especially lahars and pyroclastic density currents (PDCs) are among the most destructive volcanic hazards due to their speed, mobility, and the often-unexpected behavior these flows exhibit as they interact with topography. Mitigation of risk associated with PDCs and other volcanic mass flows depends upon accurate forecasting of magnitude and frequency, potential...

These data represent the results of surveys for western spadefoots in southern California, including both presence and non-detection data. In addition, data include environmental covariates that were hypothesized to influence the occurrence of western spadefoots, such as land cover and distance to aquatic features. These data support the following publication: Rose, J.P., Halstead, B.J

This data product consists of a database of population change and abundance estimates for North American birds, estimated from North American Breeding Bird Survey (BBS) data. Data are presented for 546 species of birds in 4 spreadsheets containing trend estimates and annual indices for 2 time periods. Estimates are derived for each species using the 1 of 4 alternative models, and a cross

This archive contains the data used to (1) summarize the hydrogeology and update the hydrogeologic framework of the Antlers aquifer in southeastern Oklahoma, and (2) develop a conceptual groundwater-flow model and water budget to estimate recharge to the Antlers aquifer during 1980–2022 as part of a hydrologic investigation (the model documentation report is available at https://doi.org...

This data release presents whole-rock geochemical data for a suite of silicic igneous and magmatic-hydrothermal rocks from the western Cordillera of the United States. Samples were mainly collected from Eocene to Miocene high-silica igneous rocks and other nearby igneous and hydrothermal±magmatic rocks. These data were collected to help define highly evolved magma systems that can be...

The use of data analytics and digital mineral prospectivity mapping has become increasingly important to mineral resource assessment in recent years. Necessary information for many forms of such modeling are expert-validated training sets. Previous work defined occurrence and grade and tonnage models for Climax-type porphyry molybdenum deposits (Singer and others, 1986; Ludington and...

This data set includes acoustic telemetry detection data and biological attributes for walleye and grass carp in the Sandusky River and Bay, OH. The detection data also includes information about the receivers that recorded the detection of acoustic telemetry tags implanted in walleye and grass carp from from 2014 to 2021. Receiver attributes include location and deployment history of...

A series of gold tube pyrolysis experiments (72 hrs, 300–600 °C) conducted on a graptolite-rich lower Paleozoic marine shale generated pyrolysis residues for a comprehensive evaluation of the molecular and structural variability of three types of graptolite periderm, namely granular, non-granular, and nodular graptolite. Raman spectroscopy in combination with organic petrology and field...

This publication provides digital flight line data for a high-resolution magnetic and radiometric survey over part of central Arkansas and southern Missouri. The airborne geophysical survey was funded by the Earth Mapping Resources Initiative and was designed to meet the complimentary needs related to geologic mapping and mineral resource research. The survey covers an irregularly shaped...

Between 1900 and 1932, a copper (Cu) mine operated near Gay, Michigan, along the shore of Lake Superior, discharged approximately 22.8 million metric tons of waste material known as ‘stamp sands’ (SS) to a nearby beach. This pile of SS has migrated via wind and rain along the beaches in northern Grand Traverse Bay and into Buffalo Reef, an important spawning area for Lake Trout and Lake...

These data and code were collected to support the development of a modeling framework that integrates local daily weather conditions and land cover with individual energetics and morphology to simulate mallard (Anas platyrhynchos) and northern pintail (Anas acuta) migration across the Northern Hemisphere.The simulated birds move across a discretized landscape of 20 by 20 mile nodes...
