Everglades National Park sediment elevation and marker horizon data release

This data set represents the relevant study site information for the Everglades National Park LTER sediment elevation table - marker horizon study. Nine SETs study sites are located near U.S. Geological Survey (USGS) hydrological stations in Everglades National Park. The coupling of coastal sediment elevation with Hydrology data is important aid in evaluating sea level changes influences to coasta

Numerical model of Submerged Aquatic Vegetation (SAV) growth dynamics in West Falmouth Harbor

The development of Submerged Aquatic Vegetation (SAV) growth model within the Coupled Ocean-Atmosphere-Wave-Sediment Transport (COAWST) model leads to a change in SAV biomass. The SAV biomass is computed from temperature, nutrient loading and light predictions obtained from coupled hydrodynamics (temperature), bio-geochemistry (nutrients) and bio-optical (light) models. In exchange, the growth of

Characterization of whooping crane migrations and stopover sites used in the Central Flyway, 2010-2016

These data were developed to support an effort to characterize migration strategies in the U.S. Great Plains and Canadian Prairies and to explore sources of heterogeneity in their migration strategy, including space use, timing, and performance. Data come from locations and other information related to 58 marked Whooping Cranes (Grus americana) from 2010-2016. These data represent basic informatio

Point data for four case studies related to testing of multi-order hydrologic position

The location of a point (or pixel) within the conterminous U.S. can be assigned based on its position relative to the Nation's stream network. Two metrics are recognized: lateral position (LP) and distance from stream to divide (DSD). And given that a point can have different positions in different hydrologic orders the term multi-order hydrologic position (MOHP) is used to describe the ensemble

Aerial Imagery Captured at Nesting Pacific Black Brant (Branta bernicla nigricans) Colonies on the Yukon-Kuskokwim Delta, Alaska, 1993-2016

This data set contains one table of the habitat classifications from imagery captured during aerial photographic surveys at the five primary Pacific black brant colonies on the Yukon-Kuskokwim Delta in western Alaska from 1993-2016.

Plasmodium Parasite Infection Data from Mosquitoes Collected in South-central Alaska, 2016

This data set includes two tables associated with a study of Plasmodium parasite infection in mosquitoes collected in south-central Alaska during the summer of 2016. The first table contains data regarding mosquito collection from three sites using CO2 baited CDC light traps. Mosquitoes were sorted and pooled according to collection date, genus, and location and subsequently screened for Plasmodiu

Laboratory studies on the thermal biology of freshwater mussels and their host fish species

Data are included for laboratory studies evaluating the thermal biology of several freshwater mussel species and their host fish including dwarf wedgemussel (Alasmidonta heterodon), brook floater (Alasmidonta varicosa), creeper (Strophitus undulatus), eastern elliptio mussel (Elliptio complanata), tesselated darter (Etheostoma olmstedi), and slimy sculpin (Cottus cognatus). Thermal endpoints inclu

Southern Guam watershed modeling and Fena Valley Reservoir water-balance model input files for historic (1990-2009) and future (2080-2099) climate conditions

This data release contains the input files for the watershed and water-balance models that simulate historic (1990-2009) and future (2080-2099) climate conditions on Guam. These simulations are described in the associated Scientific Investigations Report, "Water Resources on Guam-Potential Impacts of and Adaptive Response to Climate Change" by Stephen B. Gingerich, Adam G. Johnson, Sarah N. Rosa,

Regional Trends of Isotopic Composition in Total Gaseous Mercury Across the United States

The dataset presented here represents the concentrations and stable isotopic composition of gaseous mercury (Hg) for 31 sites across the United States. This national-scale monitoring effort was performed by the National Atmospheric Deposition Program (NADP) and the USGS over a two-year period (March 2016 - May 2018). The network includes a highly diverse set of sites ranging from remote (e.g. Dena

Dissolved Noble Gas Concentrations and Modeled Recharge Temperatures for Groundwater from Northern Sierra Nevada Foothills Shallow Aquifer Assessment Study Units, 2015-2017: Results from the California GAMA Priority Basin Project

This data release documents 155 sets of dissolved noble gas analyses (neon, argon, krypton, xenon) and 153 modeled recharge temperatures for groundwater sampled from domestic water supply wells and springs throughout the northern Sierra Nevada foothills as part of the California State Water Resources Control Board's Groundwater Ambient Monitoring and Assessment (GAMA) Program in 2015-2017. Data fr

Data Release: The effects of wildfire on snow water resources estimated from canopy disturbance patterns and meteorological conditions

This data release contains model input and output data associated with a published report (The effects of wildfire on snow water resources estimated from canopy disturbance patterns and meteorological conditions [Moeser, Broxton and Harpold, 2019]) where specific descriptions of the data can be found. The input data are derived from pre- and post-fire aerial LiDAR acquired in June 2010 and May 201

UAS-based remotely sensed data and field measurements of flow depth and velocity from the Blue River, Colorado, October 17-18, 2019

To suport an investigation of the feasibility of measuring river discharge using remotely sensed data acquired from an unmanned aircraft system (UAS), several types of remotely sensed data and field measurements were collected from two cross-sections on the Blue River in Colorado, just upstream of its confluence with the upper Colorado River, on October 18, 2018. This parent data release includes
