Fatty acid tissue concentrations of laboratory fed Lampsilis cardium mussels Fatty acid tissue concentrations of laboratory fed Lampsilis cardium mussels

The role of disease in freshwater mussel declines has been largely ignored due to the lack of appropriate diagnostic tools and metabolomic markers of stress. Mussels in this study were either fed a prepared diet or unfed and their condition was assessed with the observed changes in fatty acid content of their tissue. This dataset contains quantitative fatty acid data from nonlethal...

Federal Lands Greenhouse Gas Emissions and Sequestration in the United States: Estimates 2005-22 - Data Federal Lands Greenhouse Gas Emissions and Sequestration in the United States: Estimates 2005-22 - Data

This dataset includes eighteen years of emissions and sequestration estimates (2005-2022) in two separate tables. Table 1 includes the greenhouse gas emissions from the combustion and extraction of fossil fuels on Federal mineral lands. Table 2 is the emissions and sequestration from ecosystem processes on Federal surface lands. The fossil fuel related estimates include the greenhouse...

Fiber-optic distributed temperature sensing, seepage meter, vertical temperature profiler, water level, water quality, and streambed thermal property data collected to better understand groundwater and surface water connectivity at two sites in the Illino Fiber-optic distributed temperature sensing, seepage meter, vertical temperature profiler, water level, water quality, and streambed thermal property data collected to better understand groundwater and surface water connectivity at two sites in the Illino

As part of the US Geological Survey's Next Generation Water Observing Systems Program (NGWOS) Research and Development efforts in the Illinois River Basin, two intensive technology 'testbed' locations were established for the purpose of conducting a detailed groundwater and surface water interaction study regarding the fate and transport of excess nutrients. Specifically, nitrate is...

Field Notebooks from Loch Vale watershed, Rocky Mountain National Park, research from 1981 through 2023 Field Notebooks from Loch Vale watershed, Rocky Mountain National Park, research from 1981 through 2023

These files consist of scanned field notebooks from long-term research and monitoring conducted in the Loch Vale watershed, Rocky Mountain National Park from June 17, 1981, through September 19, 2023. There are 72 individual PDF files. They are accompanied by a spreadsheet that serves as a pointer to the contents of each notebook, including the range of years in each, start and end dates...

Field observation of wind waves and current velocity (2020) along the Fog Point Living Shoreline, Maryland Field observation of wind waves and current velocity (2020) along the Fog Point Living Shoreline, Maryland

This dataset contains measurements of wave height, peak wave period, and water depth taken every 0.5 hours from February 13 to June 12, 2020, at three wave gauge locations along the Fog Point shoreline in Martin National Wildlife Refuge, Maryland. These wave gauges were continuously sampled at 10 Hz, capturing 20-minute bursts every 30 minutes (peak wave periods longer than 7s were...

Field Site Locations from Phragmites Bioherbicide 2023 Field Experiment in Southeast Michigan Field Site Locations from Phragmites Bioherbicide 2023 Field Experiment in Southeast Michigan

This dataset represents the locations of experimental plots that were used during the Phragmites Bioherbicide 2023 field experiment. To meet the criteria for selection, a site must have relatively dry soil with no standing water, have two or more large monotypic stands of Phragmites australis, and be easily accessible by vehicle. Experimental plots were created at these sites and one of...

This is a collection of tables and graphs showing information on sample collection rates and types and photography rates.

Field-informed plant functional and species cover related to fuels treatment boundaries observed in 2021 in southwestern Idaho Field-informed plant functional and species cover related to fuels treatment boundaries observed in 2021 in southwestern Idaho

Data includes species cover of cheatgrass (BRTE) and Russian thistle (SATR), as well as functional group cover of Sandberg's bluegrass (POSE), bare ground, litter, and shrubs for the year of 2021.

Fire records (levoglucosan, mannosan, and galactosan) recorded in the deep Denali, AK ice core from ~360 to 2013 CE Fire records (levoglucosan, mannosan, and galactosan) recorded in the deep Denali, AK ice core from ~360 to 2013 CE

Monosaccharide anhydrides (MAs), or anhydrosugars which include levoglucosan, mannosan, and galactosan are combustion products of cellulose and hemicellulose that are used as biomass burning tracers. These fire biomarkers are incorporated into smoke plumes, transported through the atmosphere, and return to the surface through wet and dry deposition that can be archived in ice cores. Here...

First and Second Record of US-RIIS Vascular Plant Species in Contiguous United States First and Second Record of US-RIIS Vascular Plant Species in Contiguous United States

This is a dataset containing the first and second record of georeferenced observations of introduced and invasive vascular plant species in the contiguous United States (CONUS). Non-native plant species were identified using the United States Register of Introduced and Invasive Species (US-RIIS) list. After identifying a list of plants non-native to CONUS, we obtained presence data from...

Fish communities in PA and MD Piedmont mixed agricultural streams, 2023 Fish communities in PA and MD Piedmont mixed agricultural streams, 2023

From 2-27 June, 2023, a Virginia Tech team of 5 sampled the fish community in 30 Piedmont streams (lower Susquehanna River and upper Chesapeake Bay tributaries, Pennsylvania and Maryland, USA) spanning a gradient of agricultural intensity as part of a larger stream-health study including other teams who surveyed geomorphology, water quality, flow, temperature, and macroinvertebrates at...
