Metapopulation model inputs for riverine fish with applications including native and invasive fish passage scenarios and silver carp control scenarios within the Mississippi River Basin Metapopulation model inputs for riverine fish with applications including native and invasive fish passage scenarios and silver carp control scenarios within the Mississippi River Basin
This data release contains data inputs for the Metapopulation Integral Projection Model (MetaIPM). These inputs include demographic rate data (such as fish growth) and movement rate data (such as fish movement across river pools). The data are designed to be downloaded by a Shiny Application (point-and-click version of the model). Each species and scenario requires its own data inputs...
Metaproteomic Data Associated with Produced Waters collected from the Antrim Shale in Michigan, 2023 Metaproteomic Data Associated with Produced Waters collected from the Antrim Shale in Michigan, 2023
This data release contains metaproteomics data from subsurface methanogenic communities in an Antrim Shale (Michigan basin, MI) natural gas well. The subsurface microbial communities have interacted with produced waters that were exposed to ambient surficial conditions prior to injection of the produced waters into the well. These data are used in a related publication to understand...
Meteorological data from Cape Cod National Seashore, Massachusetts Meteorological data from Cape Cod National Seashore, Massachusetts
Meteorological data were collected at Marconi and Head of the Meadow Beaches on Cape Cod National Seashore, MA as part of a multi-year monitoring study of nearshore sand transport and white shark behavior. The overarching goal of the study is to characterize beach and nearshore morphology, assess temporal variability, and measure wave runup to calibrate USGS total water level forecasts...
Method development data – Stabilization of volatile silicon species in hydrofluoric acid (HF) digests of biological samples for HF-free silicon analysis by ICP-MS Method development data – Stabilization of volatile silicon species in hydrofluoric acid (HF) digests of biological samples for HF-free silicon analysis by ICP-MS
Experiments were conducted in the U.S. Geological Survey (USGS) Aqueous Trace Element Analysis Laboratory (ATEAL) in Denver, CO to support development and validation of a method for preparing biological materials for silicon analysis by solution phase inductively coupled plasma mass spectrometry (ICP-MS). The objective was to stabilize volatile silicon species resulting from a digestion...
Methods for estimating selected low-flow frequency and mean annual flow statistics at gaged and ungaged locations on streams in Georgia, North Carolina, and South Carolina, 2022—Data Methods for estimating selected low-flow frequency and mean annual flow statistics at gaged and ungaged locations on streams in Georgia, North Carolina, and South Carolina, 2022—Data
Based on hydrologic data through the 2022 water year (October 1 to September 30), the U.S. Geological Survey South Atlantic Water Science Center updated low-flow frequency, mean annual flow, and flow-duration statistics at 843 streamgages in and near Georgia, North Carolina, and South Carolina. Data from 604 of those streamgages, on streams not substantially affected by regulation or...
Microfossil samples from mottled mudstones and adjacent units in Northern and Central California Microfossil samples from mottled mudstones and adjacent units in Northern and Central California
This digital database is an inventory of microfossil samples in units or formations containing mottled mudstones and units or formations stratigraphically above and below units containing mottled mudstones. This database contains detailed information about each sample (e.g., USGS laboratory number, field number, collector and date collected, location quadrangle etc.) and database entries...
Microprobe data for rock samples from the Escanaba Trough (Gorda Ridge) Microprobe data for rock samples from the Escanaba Trough (Gorda Ridge)
This data release contains electron microprobe data collected on thin sections made from rock samples collected from the Escanaba Trough hydrothermal vent field, Gorda Ridge, in the northeast Pacific Ocean. These data were collected in 2022 on expedition TN403 (USGS Field Activity 2022-621-FA). Samples were taken to the USGS Pacific Coastal Marine Science Center for subsampling and...
MidFish: A Large-Scale Aggregation of State Fisheries Data from the Midwestern United States from 1940 - 2023 MidFish: A Large-Scale Aggregation of State Fisheries Data from the Midwestern United States from 1940 - 2023
Lakes in the Midwestern United States support valuable recreational, subsistence, and tribal fisheries. Fisheries assessments that support management decisions are typically conducted within political boundaries and at intervals that limit their spatial and temporal scope. Data aggregation across lakes and regions facilitates research extending across ecological gradients and...
Mineral, mineral chemistry, and geochronology data for regolith samples, Mount Weld, Western Australia Mineral, mineral chemistry, and geochronology data for regolith samples, Mount Weld, Western Australia
This U.S. Geological Survey (USGS) data release contains analytical data from a suite of mineral samples collected from the Mount Weld carbonatite complex, western Australia. This complex hosts the largest producing rare earth element (REE) mine outside of China. The REEs are mined from the weathered material, a laterite, derived from an underlying carbonatite. Samples were collected...
Mississippi barrier island land area change 1984–2025 Mississippi barrier island land area change 1984–2025
These datasets are part of an effort associated with the Mississippi Coastal Improvements Program to assess Mississippi Barrier Islands. The U.S. Army Corps of Engineers (USACE) restored sections of Cat and Ship Island. Over 142 hectares (350 acres) of sediment were placed on Cat Island during 2017 with the goal of restoring and fortifying the beaches and dunes from westward wave energy...
Mississippi Barrier Islands Habitat Classification, National Wetlands Inventory, December 2015: (Cat Island, Ship Island, Horn Island, and Petit Bois Island) Mississippi Barrier Islands Habitat Classification, National Wetlands Inventory, December 2015: (Cat Island, Ship Island, Horn Island, and Petit Bois Island)
This data set consists of digital data describing wetlands and uplands habitats for the Mississippi Coastal Improvements Program (MsCIP) area, consisting of Cat, Ship, Horn and Petit Bois Islands for the year 2021. Wetlands were classified using the Cowardin, et al., (1979) wetlands classification scheme to the level of freshwater and tidal salinity modifiers. For this dataset, upland...
