Hydroacoustic data from central Lake Erie, 2010-2019

Hydroacoustic estimates of fish density are used for fisheries management in central Lake Erie. Hydroacoustic data were collected along up to four cross-lake transects in central Lake Erie July 2010 through July 2019. Software-generated raw variables used for calculating estimates of hydroacoustic fish densities are presented here.

MODFLOW-2005 models used to simulate effects of pumping in the Death Valley Regional Groundwater Flow System, Nevada and California—Selected management scenarios projected to 2120

A three-dimensional, groundwater-flow model developed by Halford and Jackson (https://doi.org/10.3133/pp1863) was used to simulate effects of future (2020—2120) groundwater pumping on water levels and natural discharges in the Alkali Flat–Furnace Creek Ranch (AFFCR), Ash Meadows, Pahute Mesa–Oasis Valley (PMOV), and Pahrump to Death Valley South (PDVS) groundwater basins, southern Nevada and Calif

Suspended-sediment, bed-sediment, and in-channel topographical data at the Green River at Mineral Bottom near Canyonlands National Park, and Colorado River at Potash, UT stream gages

Sediment Data: These data include (1) physical suspended-sediment sample data including suspended silt and clay concentration, suspended-sand concentration, and suspended-sand grain size distribution, (2) bed-sediment sample data with complete grain size analyses, and (3) 15-minute acoustical sediment data measured using a multifrequency array (1MHz and 2MHz) of sidelooking acoustic Doppler profil

Tracking Data for Northern Fulmars (Fulmarus glacialis)

This metadata document describes the data contained in the "rawData" folder of this data package. This data package contains all data collected by the Argos System from 19 satellite transmitters attached to Northern Fulmars on their breeding range in the Bering Sea and northern Gulf of Alaska, 2001-2006. Five data files are included in the "rawData" folder of this data package. Two data files (wit

Tracking Data for Tufted Puffins (Fratercula cirrhata)

This metadata document describes the data contained in the "rawData" folder of this data package. This data package contains all data collected by the Argos System from 5 satellite transmitters attached to Tufted puffins on the Barren Islands in the northern Gulf of Alaska, 1995. Five data files are included in the "rawData" folder of this data package. Two data files (with identical content) cont

Invertebrate community data from native trout lakes and streams in the Southern Rocky Mountains

Native trout in the West suffer a high degree of vulnerability, as highlighted by cutthroat trout, a group of 14 subspecies, most of which have been petitioned for listing under the Endangered Species Act (ESA). In the Southern Rocky Mountains, greenback cutthroat trout (Oncorhynchus clarkii stomias; GBCT) are listed as threatened under the ESA, and few populations remain, in part because of the i

Dataset from 2015-2016 thermal and behavior monitoring of Argentine giant tegus in Everglades, Florida

Thermal data collected from iButton temperature loggers implanted into research animals (Argentine giant tegus) and in their surrounding environment. Tegus undergo winter dormancy (hibernation) to cope with colder temperatures, and we studied the thermal habits of wild tegus within their invaded range in southern Florida, USA. We used radiotelemetry and trail cameras to verify dates of above-groun

Bird Behavior and Mortality in Relation to Power Lines in Prairie Habitats, North Dakota, 1981to1982

A biologist and field crew from Northern Prairie Wildlife Research Center observed bird flights at 7study sites, twice weekly during two spring and two fall migration periods between April 3, 1981 and May 20, 1982. Study sites were located in south-central North Dakota in Barnes, Kidder, and Stutsman counties. The database includes flight observation's of bird species in the vicinity of power line

Known Terrestrial Analog Sites for Planetary Science

A point layer of sites known to be useful analogs for planetary science, such as impact craters, dunes, volcanoes, and other processes observed on bodies across the solar system.

Mars Dune Digital Database - Merged

The Mars Global Digital Dune Database provides a comprehensive and quantitative view of the geographic distribution of dune fields from 65° N to 65° S latitude. The database encompasses ~ 550 dune fields, covering ~ 70,000 km2, with an estimated total volume between 3,600 km3 and 13,400 km3. Over 2300 selected Thermal Emission Imaging System (THEMIS) infrared (IR), THEMIS visible (VIS) and Mars Or

Potential productivity and change estimates for eight grassland species to evaluate vulnerability to climate change in the southern Great Plains

This data set includes the relative production scenarios for eight (8) grass species based on linear models from Epstein, et al. (1998). We selected two indicator species for each community: shortgrass prairie: blue grama (Bouteloua gracilis; BOGR) and buffalo grass (Bouteloua dactyloides; BODA); mixedgrass prairie: sideoats grama (Bouteloua curtipendula; BOCU) and little bluestem (Schizachyrium s

Compilation and Assessment of Resource Values and Hazards to Inform Transportation and Associated Land-use Planning

Management of transportation networks is affected by, and has effects on, natural and cultural resources through direct and indirect interactions. Until recently, the availability of such spatially explicit information has been limited; however, the data released here to the public will prove valuable for comparing existing networks and planning options with respect to potential impact to, or from
