Data Release: Germination and growth of Montezuma cypress (Taxodium mucronatum) from the Nazas River to experimental salinity treatments Data Release: Germination and growth of Montezuma cypress (Taxodium mucronatum) from the Nazas River to experimental salinity treatments
During March and April of 2018, viable seeds were collected from Cañón de Fernández State Park in Lerdo, Durango and sent to Lafayette, LA for germination. This study tested the seedling growth and germination of Taxodium mucronatum from the Nazas River watershed at different salinity concentrations representing freshwater, moderate salinity, and high salinity.
Data Release: Mercury accumulation potential of aquatic plant species in West Dongting Lake, China Data Release: Mercury accumulation potential of aquatic plant species in West Dongting Lake, China
An ecological study on mercury contamination in the wetland of West Dongting Lake in China. This study measured the total mercury concentration in the soil and compared it to the measured total concentration of mercury in the above and below ground tissue of different plant species on the floodplain of West Dongting Lake. Bioconcentration, bioaccumulation, and translocation factors were...
Data Release: Modeling coastal salinity regime for biological application Data Release: Modeling coastal salinity regime for biological application
Salinity regimes in coastal ecosystems are highly dynamic and driven by complex geomorphic and hydrological processes. Estuarine biota are generally adapted to salinity fluctuation, but are vulnerable to salinity extremes. Characterizing coastal salinity regime for ecological studies therefore requires representing extremes of salinity ranges at various time scales relevant to ecology (e...
Data Release: Seed banks of rare Physostegia correllii in Lady Bird Johnson Lake, Austin, Texas Data Release: Seed banks of rare Physostegia correllii in Lady Bird Johnson Lake, Austin, Texas
Soil samples were collected from Lady Bird Johnson Lake, Austin, Texas in 2019 to generate seed bank data for the rare plant Physostegia correllii. Seed germination data was produced from the soil samples kept in a greenhouse at the Wetland and Aquatic Research Center in Lafayette, LA.
Data showing similar movement ecology between mallards infected and not infected with highly pathogenic avian influenza H5N1 Data showing similar movement ecology between mallards infected and not infected with highly pathogenic avian influenza H5N1
These data, which support a paired USGS publication, document the movement and infection status of mallards captured, marked, and tested at a wintering site in Tennessee. Data document differences in movement ecology between mallards infected and not infected with HPAI H5N1.
Data supporting 'Linking fire-induced evapotranspiration shifts to streamflow magnitude and timing in the western United States' Data supporting 'Linking fire-induced evapotranspiration shifts to streamflow magnitude and timing in the western United States'
The impact of wildfire on water availability is a critical issue in the western United States. Because actual evapotranspiration (ETa) constitutes the largest loss in the terrestrial water budget, it has been suggested that fire-induced ETa reduction is a primary driver of elevated post-fire discharge. Ten gaged watersheds with burns exceeding 5% of their total contributing drainage area...
Data supporting a spatiotemporal trend analysis of specific conductivity, streamflow, and landscape attributes of selected sub-basins within the Delaware River watershed, 1980 to 2018 Data supporting a spatiotemporal trend analysis of specific conductivity, streamflow, and landscape attributes of selected sub-basins within the Delaware River watershed, 1980 to 2018
This data release makes available three data tables supporting a spatiotemporal analysis of riverine conductivity and streamflow trends within the Delaware River Basin. The listed datasets include baseflow and total flow time series for selected gaged basins, watershed attributes, water quality information and trend analysis results.
Data Supporting Analysis of Relations Between Nutrient Concentrations in the Herring River on the Ebb Tde, Near Wellfleet, Massachusetts and Environmental Conditions, 2015- 2022. Data Supporting Analysis of Relations Between Nutrient Concentrations in the Herring River on the Ebb Tde, Near Wellfleet, Massachusetts and Environmental Conditions, 2015- 2022.
This data release supports analyses of the relations between monthly average nutrient concentrations in the Herring River on the ebb tide near Wellfleet Massachusetts and monthly average precipitation, temperature, runoff, solar radiation, ocean water temperature, mean sea level, nutrient concentrations in Wellfleet Harbor, and atmospheric deposition of nitrogen 2015-2021. The...
Data supporting the 2020 and 2021 geomorphic survey of North Fork Eagle Creek, New Mexico Data supporting the 2020 and 2021 geomorphic survey of North Fork Eagle Creek, New Mexico
This U.S. Geological Survey (USGS) data release contains results from the 2020 and 2021 geomorphic survey of North Fork Eagle Creek, New Mexico. Both geomorphic surveys were conducted by the USGS, in cooperation with the Village of Ruidoso, New Mexico, and are the last set of surveys in a planned series of five annual geomorphic surveys of the stream reach located between the North Fork...
Data supporting the construction of the Three-Dimensional Geologic Map and Geology-based Seismic Velocity Model of the Sacramento-San Joaquin River Delta and surrounding region, California Data supporting the construction of the Three-Dimensional Geologic Map and Geology-based Seismic Velocity Model of the Sacramento-San Joaquin River Delta and surrounding region, California
This report includes the previously unpublished primary and derivative data sets that underpin the construction of the three dimensional (3D) geologic map of the upper part of the Earth's crust beneath the Sacramento-San Joaquin River Delta, California. The primary data is X,Y,Z locations of stratigraphic horizons and, to a much lesser extent, geologic structures where penetrated by oil...
Data Supporting Walrus Areas of Use in the Chukchi Sea During Sparse Sea Ice Cover Data Supporting Walrus Areas of Use in the Chukchi Sea During Sparse Sea Ice Cover
The dataset consists of geospatial files depicting the estimated June-to-November distribution of walrus foraging and occupancy during a four year period of sparse sea ice cover above the Chukchi Sea continental shelf (2008-2011). The walrus distribution and utilization estimates are based on location data from satellite-linked radio-tracked walruses in the Chukchi Sea (2008-2011)...
Data Tables Associated with an Analysis of the U.S. Geological Survey's Historical Water-use Data, 1985–2015 Data Tables Associated with an Analysis of the U.S. Geological Survey's Historical Water-use Data, 1985–2015
The datasets in this data release contain the results of an analysis of the U.S. Geological Survey's historical water-use data from 1985 to 2015. Data were assessed to determine the top category of water-use by volume. Data from groundwater, surface water, and total water (groundwater plus surface water) use were parsed by water type, and the top category of use by county or the...
