Coastal wetlands store carbon in their soils. Carbon is produced by emergent biomass and in-situ root growth, as well as deposited through sedimentation. Burial of aboveground carbon within soils and disruption of long-term soil carbon storage are both influenced by the fauna present in coastal wetlands. Data were used to test the hypothesis that the American Alligator (Alligator...

The US Geological Survey's Upper Midwest Environmental Sciences Center, in coordination with the US Fish and Wildlife Service's (USFWS) Branch of Migratory Bird Surveys, worked to develop, survey, and deploy an advanced aerial photography boresight in the town of Bangor, Maine. The intention of this boresight is to provide an extensive array of high-accuracy ground control points for the

The U.S. Geological Survey (USGS), in cooperation with the Texas Department of Transportation (TxDOT), deployed RQ-30 surface velocimetry sensors (hereinafter referred to as “RQ-30 sensors”) made by Sommer Messtechnik to collect radar gage-height data, cross section area, surface velocity, learned surface velocity, discharge, and learned discharge at 80 streamgages located in stream...

This data release contains a CSV dataset of the likelihood of sapling recruitment based on abundance of seedlings height classes and other stand and site-level factors. Maps accompany the CSV on how the relationship between temperature and relative survival and seedling/sapling abundance varies by size class for ten tree species in the northeastern and midwestern USA, and can be used to...

This data release contains the two intermediary variables (processed lake temperature prediction feather files and bioenergetic metrics CSV), model code in R script used to produce the outputs, and bioenergetics model prediction feather files for a set of fish bioenergetics models under current and future temperature conditions at 337 large lakes.

This dataset consists of trace organic contaminant concentrations and bacteria counts in wastewater effluents, and observed responses in fish exposed to effluents. The study was conducted from April to September 2022 at a facility located in Hutchinson, Minnesota. Nine pairs of primary-treated, activated sludge secondary treated, and membrane bioreactor secondary treated wastewater were

This data release contains two data sets: 1) the model application data for a set of dynamic total nitrogen (TN) and total phosphorus (TP) SPARROW (SPAtially Referenced Regression On Watershed attributes; Schwarz and others, 2006, https://doi.org/10.3133/tm6B3) load models that were developed for watersheds draining to Washington waters of the Salish Sea (Puget Sound region) 2005 through...

Semifusinite and fusinite macerals are formed through carbonization of plant material in naturally occurring wildfires. Both macerals, belonging to the inertinite maceral group, are carbon-rich and oxygen-poor, and are typical constituents of charcoal. The charring of plant material into charcoal serves as nature’s method for storing carbon over geological timescales. The permanence and...

This data release contains new, 40–70-year long sub-annual strontium-to-calcium ratio (Sr/Ca) records and linear extension measurements from five mid-to-late Holocene, Orbicella faveolata corals from the Dry Tortugas National Park (DT) and Marquesas Keys (MK), Florida (FL). U.S. Geological Survey (USGS) researchers used these Sr/Ca data to calculate sea-surface temperature (SST) using...

Passive integrated transponder (PIT) detections across the Upper Klamath River Basin were combined from all fish that were detected making a passage attempt at the Link River Dam fish ladder from 2008 - 2024. In July 2007, four PIT tag antennas (FS1001 Muliplexer transceiver [MUX] units) arrays which were originally installed by Biomark. In October 2023, antennas were upgraded to Biomark...

This data release provides digital flight-line and gridded data for a high-resolution airborne magnetic and radiometric survey over the central portion of the Colorado Mineral Belt, central Colorado. The Colorado Mineral Belt is a broad, northeast-southwest trending alignment of historic mining districts that have produced multiple types of commodities, including critical minerals that...

A dye trace experiment was conducted between March 2023 and September 2024 to understand the connection between treated wastewater effluent discharged to Bright Angel Wash and 13 springs and associated watersheds from Hermit Creek to Pipe Creek along the South Rim of Grand Canyon, Arizona. This data release includes information on the location of the sites (GCSR_Site_Information), time...
