Experimental Coral-Growth Data and Time-Series Imagery for Acropora palmata and Pseudodiploria strigosa in St. Croix, U.S. Virgin Islands
The U.S. Geological Survey Coral Reef Ecosystems Studies project (CREST) provides science that helps Department of Interior and other resource managers tasked with the stewardship of coral reef resources. This data release contains data on coral-growth rates and time-series photographs taken of colonies of the elkhorn coral, Acropora palmata, and the symmetrical brain coral, Pseudodiploria strigos
Grain size and charcoal abundance in sediment samples from Los Padres reservoir, Carmel River watershed, California
Sediment samples were collected from Los Padres reservoir in the Carmel River watershed, central California coast, between July 11 and 17, 2017, using a CME-45 barge-mounted drill rig, to characterize sedimentary properties in the reservoir deposits following the Soberanes Fire of 2016 and high river flows in winter 2017. Borehole samples were recovered using direct push coring with an Osterberg p
Polycyclic aromatic hydrocarbon concentrations in soil, sediment, vegetation, and water samples collected from the Arctic National Wildlife Refuge during Summer 2019
This data set documents results of analysis of samples collected from the Arctic National Wildlife Refuge during Summer 2019. Data tables include: 1. The numeric and alphanumeric identifiers for samples collected for this study and the dates these samples were collected; 2. Results data containing concentration values of individual polycyclic aromatic hydrocarbon compounds in sediment, soil, and v
Electro-olfactory responses of Grass Carp, Bighead Carp, and Silver Carp to the amino acids L-alanine, L-arginine, L-aspartic acid, L-asparagine, L-glutamine, and L‑glutamic acid
Using juvenile individuals of 3 species of carp (Family: Cyprinidae), we tested the potential for six amino acids to elicit an extracellular electro-olfactory response within the naris using gelatin-based electrodes. The amino acids L-alanine, L-arginine, L-aspartic acid, L-asparagine, L-glutamine, and L‑glutamic acid were tested on Grass Carp (Ctenopharyngodon idella), Bighead Carp (Hypophthalmic
Uranium-Thorium Ages for Late Holocene Corals from the Southeast Florida Nearshore Ridge Complex
This data release compiles Uranium-Thorium (U-Th) dating data for late Holocene coral samples collected from the Nearshore Ridge Complex (NRC) off Pompano Beach, Southeast Florida (SEFL; Figure 1). The samples were collected under Scientific Activity Licenses (SAL) from the Florida Fish and Wildlife Conservation Commission (SAL-18-1659A-SRP) and with permission from Broward County Environmental Pr
Daily average soil moisture and ancillary data from the Noah land surface model in the National Land Data Assimilation version 2 extracted for GAGES-II watersheds, 1980 to 2020
This U.S Geological Survey data release contains soil moisture, actual evapotranspiration, precipitation, and potential evapotranspiration by watershed for the United States from 1980 to 2020. Hourly values from NASA's North American Land Data Assimilation System Phase 2 (NLDAS-2) Noah model were aggregated to daily values and extracted by Geospatial Attributes of Gages for Evaluating Streamflow,
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.
Phosphorus, nitrogen, carbon, calcium, pH, and dissolved oxygen data from incubations of Colorado River water and sediment and associated ambient river water measurements
Lake Powell retains most of the phosphorus that it receives, leading to downstream phosphorus limitation. These data were compiled to examine controls on phosphorus cycling below Lake Powell in the Colorado River and from storm inputs from the Paria River. Objectives of our study were to determine how several forms of phosphorus, both organic and inorganic, were cycled under varying dissolved oxyg
Streamflow projections for southwestern United States (1975-2099)
We projected future streamflow outcomes arising from climate change for
the southwestern United States during the 21st century due to climate
change under two possible greenhouse gas concentration pathways
(RCP4.5 and 8.5). The results inform water managers about the future
risks of drought in their water resource regions by providing bounds on
the possible locations and extents of streamflow
Lower Salinas Valley Hydrologic Models: Agricultural and Municipal Water Supply and Groundwater Data (ver. 2.1, August 2024)
This digital dataset contains the datasets related to agricultural and municipal water supply and groundwater in the Lower Salinas Valley Hydrologic Models (LSVHM), including the Salinas Valley Operational Model (SVOM) and the Salinas Valley Integrated Hydrologic Model (SVIHM). Groundwater inflow and outflow data include reported groundwater pumpage and groundwater elevations obtained for the peri
Paranannizziopsis spp. associated with skin lesions in wild snakes in North America and development of a real-time PCR assay for rapid detection of the fungus in clinical samples
The emergence of ophidiomycosis (or snake fungal disease) in snakes has prompted increased awareness of the potential impacts of fungal infections on wild reptile populations. Yet, aside from Ophidiomyces ophidiicola, little is known about other mycoses affecting wild reptiles. The closely related genus Paranannizziopsis has been associated with dermatomycosis in snakes and tuataras in captive col
Egg Mass Counts from Foothill Yellow-Legged Frogs (Rana boylii) in California from 1992-2021
We compiled time series of egg mass counts (an index of adult female abundance) from Rana boylii populations in 36 focal streams and fit a Multiple Population Viability Analysis (MPVA) model to quantify how streamflow metrics, stream temperature, and surrounding land cover affect population growth. In addition, data on streamflow, stream temperature, and surrounding land cover for each stream were
