Modeled habitat suitability for five rare plants (Aliciella formosa, Sclerocactus cloverae, Townsendia gypsophila, Astragalus ripleyi, and Cymopterus spellenbergii) in New Mexico
This data bundle contains the final outputs from a VisTrails/SAHM workflow to model the potential distribution of 5 rare plants (Aliciella formosa, Sclerocactus cloverae, Townsendia gypsophila, Astragalus ripleyi, and Cymopterus spellenbergii) in northern New Mexico. These models utilized field data of spatially thinned occurrence locations and random background locations or random plus absence lo
Enhanced Terrain Imagery of the Cumberland 30 x 60 Minute Quadrangle from Lidar-Derived Elevation Models at 3-Meter Resolution
This imagery dataset consists of 3-meter resolution, lidar-derived imagery of the Cumberland 30 x 60 minute quadrangle in Pennsylvania, West Virginia and Maryland. The source data used to construct this imagery consists of 1-meter lidar-derived digital elevation models (DEMs). The lidar source data were compiled from different acquisitions published between 2019 and 2023. The data were processed u
Riverine carbon form and flow data from a temperate forested watershed in Southeast Alaska (2021)
Data from high frequency sampling of multiple carbon forms were collected in a predominately rain-fed watershed in Southeast Alaska during the main run-off season (May-October 2021). The dataset includes dissolved organic carbon, particulate organic carbon, coarse particulate organic carbon, and invertebrate biomass carbon point samples and daily stream flow. The objective of this study was to col
Sea-level rise and high tide flooding inundation probability and depth statistics in Nassau and Duval Counties, Florida
This dataset includes elevation-based probability and depth statistics for estimating inundation under various sea-level rise and high tide flooding scenarios in and around the National Park Service’s Timucuan Ecological and Historic Preserve. These datasets were developed using 1-m digital elevation model (DEM) from 2018 with reduced elevation error in coastal wetlands (McHenry and others, 2023).
Cone Penetration Test data of Paleoliquefaction sites in Washington and Oregon
In many parts of the United States and around the globe, the instrumental earthquake record is insufficient to characterize seismic hazard or constrain potential ground motion intensities from individual sources. This lack of data is particularly acute for the Cascadia Subduction Zone (CSZ) of the U.S. Pacific Northwest, where paleoseismic evidence suggests a long history of large megathrust event
FLOwPER Database: StreamFLOw PERmanence field observations, Jan 2021 - Dec 2021
IMPORTANT NOTE: This dataset includes spatial locations where streamflow permanence observations (continuous flow, discontinuous flow, and dry) were recorded using the FLOwPER (FLOw PERmanence) field survey available in the Survey 123. Additional information to describe the field conditions are included as part of the survey. Field observations in the FLOwPER Database have not been processed for q
Nitrogen, phosphorus, and suspended-sediment loads and trends measured at the Chesapeake Bay River Input Monitoring stations: Water years 1985-2023
Nitrogen, phosphorus, and suspended-sediment loads, and changes in loads, in major rivers across the Chesapeake Bay watershed have been calculated using monitoring data from the Chesapeake Bay River Input Monitoring (RIM) Network stations for the period 1985 through 2023. Nutrient and suspended-sediment loads and changes in loads were determined by applying a weighted regression approach called WR
Modeled Nutrient and Sediment Concentrations from Major Rivers in Illinois Based on Continuous Monitoring from October 1, 2015, through September 30, 2022
During water years 2016–2022 (a water year begins on October 1 and ends on September 30), the U.S. Geological Survey (USGS), in cooperation with the Illinois Environmental Protection Agency (Illinois EPA), operated continuous monitoring stations on eight of the major rivers in Illinois to better quantify nutrient and sediment loadings from the State of Illinois to the Mississippi River. This data
Airborne electromagnetic and magnetic survey of the Alabama Graphite-Vanadium Belt and surrounding regions, 2023
Airborne electromagnetic (AEM) and magnetic survey data were collected during March and April 2023 over a distance of 9,000 line kilometers in east central Alabama. Data were acquired by SkyTEM Canada Inc. with the SkyTEM 306HPM time-domain helicopter-borne electromagnetic system together with a Geometrics G822A cesium vapor magnetometer. The survey was acquired at a nominal flight height of 35 -
Plankton occurrence in the Willamette River, Portland, Oregon
This data release contains plankton sampling results collected in the Willamette River in Portland, Oregon. The data release will be updated with new results as they are collected. All samples collected on 05/14/2024 were from USGS station 453027122400000 (Willamette River below the Holgate Channel). Water temperature, specific conductance, dissolved oxygen, pH, and chlorophyll and phycocyanin flu
Waterfowl (Anatidae) Brood Data, Maine, 1977 – 1994
Our data include detailed information about 12 species of Anatidae broods encountered on four study areas in Maine during 1977–1994 as one dataset. The second dataset provides the characteristics of the wetlands which were monitored during the studies. The third dataset enumerates the effort (such as numbers of visits to each wetland) to determine numbers of broods and the number of young that rea
Range-wide salamander densities reveal a key component of terrestrial vertebrate biomass in eastern North American forests
These data have been collected by a collaborative and coordinated research network, SPARCnet (Salamander Population and Adaptation Research Collaboration network). We collected these data to examine patterns in seasonal and latitudinal variation in population density. This data can be used to estimate local salamander biomass, correcting for imperfect detection, and then compare these to estimates
