Crop Water Use in the Central Valley of California using Landsat-derived evapotranspiration
Understanding how different crops use water over time is essential for planning and managing water allocation, water rights, and agricultural production. The main objective of this paper is to characterize the spatiotemporal dynamics of crop water use in the Central Valley of California using Landsat-based annual actual evapotranspiration (ETa) from 2008-2018 derived from the Operational Simplifie
Thermal Data and Navigation for T-3 (Fletcher's) Ice Island Arctic Ocean Heat Flow Studies, 1963-73 (ver. 1.1 December 2022)
The T-3 (Fletcher's) Ice Island in the Arctic Ocean was the site of a scientific research station re-established by the Naval Arctic Research Laboratory starting in 1962. Starting in 1963, the USGS acquired marine heat flow data and coincident sediment cores at sites in Canada Basin, Nautilus Basin, Mendeleev Ridge, and Alpha Ridge as the ice island drifted in the Amerasian Basin. At least 584 hea
Post-expedition report for USGS T-3 Ice Island heat flow measurements in the High Arctic Ocean, 1963-1973
In February 1963, the U.S. Geological Survey (USGS) began a study of heat flow in the Arctic Ocean Basin and acquired data at 356 sites in Canada Basin and Nautilus Basin and on Alpha-Mendeleev Ridge by the end of the project in 1973. The USGS heat flow and associated piston coring operations were conducted from a scientific station on the freely drifting T-3 Ice island (also known as Fletcher's
Crustal Architecture Beneath the Southern Midcontinent (USA) -- Data Grids and 3D Geophysical Models
Regional grid files and 3D voxel models were used to study crustal architecture beneath the Southern Midcontinent (USA) by McCafferty and others (2019). The study covered a rectangular, multi-state area of 924 by 924 kilometers centered on Missouri, and a corresponding volume extending from the topographic surface to a depth of 50 kilometers below sea level. The grid files consist of surface grids
Barrier island geomorphology and shorebird habitat metrics: Four sites in New York, New Jersey, and Virginia, 2010-2014
Understanding how sea-level rise will affect coastal landforms and the species and habitats they support is critical for crafting approaches that balance the needs of humans and native species. Given this increasing need to forecast sea-level rise effects on barrier islands in the near and long terms, we are developing Bayesian networks to evaluate and to forecast the cascading effects of sea-leve
Factors affecting prey availability and habitat use of nonbreeding piping plovers (Charadrius melodus) in coastal Louisiana
Dataset includes observations of Piping Plovers made during winter shorebird surveys on Whiskey and Trinity Islands in Terrebonne Parish, Louisiana during the winter of 2013-2014. Attributes include location, behavioral, and microhabitat data as well as references to these data points in our local Access database.
Maumee River, Toledo, Ohio Mixing Data 2013
These data were collected to examine water mixing in the lower Maumee River to determine the extent to which water from Lake Erie backflows into the river, and under what conditions this occurs. We used a combination of fixed hydrologic gauges; water chemistry including stable isotopes and conservative tracers; and direct physical measurements to estimate the percentages of lake and river water at
Laboratory Incubation results from 2015 for bacterial cell counts, carbon use efficiency, growth efficiency, and dissolved organic matter chemistry from four glacier outflows and four rock glacier outflows in Colorado
Bacterial Data include results of incubations of lakewater bacteria with dissolved organic matter extracted from Colorado glacier or rock glacier outflows in 2015. Cells were counted pre- and post- incubations. The "Counts" tab is the number of cells counted in each view of the microscope using the acridine orange method. "C Calculations" tab is the calculation of carbon as bacterial biomass from
Diet items consumed by wild-caught black carp (Mylopharyngodon piceus) in the U.S.
An inventory (enumeration and taxonomic identification) of diet items consumed by wild-caught black carp, based on the examination of gut contents from fish that were collected in the lower Mississippi River drainage of the U.S.
Petrologic and Mineral Physics Database for use with the USGS National Crustal Model - Data Release
We present a petrologic and mineral physics database as part of the USGS National Crustal Model (NCM) for the western United States. Each of 209 geologic units, 134 of which are currently part of the geologic framework within the NCM, is assigned a mineralogical composition according to generalized classifications with some refinement for specific geologic formations. The mineral physics database
Sylvatic Plague Vaccine field trials flea data
hese data were collected as part of a field trial to test the efficacy of a sylvatic plague vaccine (see Rocke et al., 2017 for details). Vaccine and control plots were selected randomly from the available sites at each location. At least 1 week and no more than 2 months post-baiting each year, local collaborators captured, marked and sampled prairie dogs for a minimum of 3 trap days. Both plots
iTOUGH2-EOS7C model used to analyze multiphase flow and hydromechanical coupling in underpressured shale at the Bruce Nuclear Site, Ontario, Canada
Using iTOUGH2-EOS7C, a simple 1-D model was developed to represent a site in Ontario, Canada which is being considered
for nuclear waste disposal. The site exhibits substantially underpressured water and potential evidence for gas phase methane
within a thick section of sedimentary rocks. To investigate possible mechanisms for the development of the underpressure in a
multiphase system, hydr
