Great Lakes Restoration Initiative's Terrestrial Habitats & Connectivity Work Group's Pilot Area's Post-Fiscal Year 2024 Open Habitat Connectivity Great Lakes Restoration Initiative's Terrestrial Habitats & Connectivity Work Group's Pilot Area's Post-Fiscal Year 2024 Open Habitat Connectivity
This dataset is the fourth installment of a yearly connectivity update for open habitat within the Great Lakes Restoration Initiative's (GLRI) Terrestrial Habitats & Connectivity (TH&C) work group's Pilot Area. The Pilot Area is a region of the northern Great Lakes Basin between Ashland, Wisconsin and the Keweenaw Peninsula and is bounded by Lake Superior in the north and the basin...
Geochemical and mineralogical data for samples from the Blue Road outcrop of the Cretaceous Mancos Shale, Emery County, Utah Geochemical and mineralogical data for samples from the Blue Road outcrop of the Cretaceous Mancos Shale, Emery County, Utah
Bulk organic geochemical, major and trace element, and mineralogical measurements were made on samples of the Late Cretaceous Mancos Shale collected from the Blue Road outcrop off of South Millers Canyon Road/Blue Road approximately 3.5 miles south of U.S. Interstate 70 (Emery County, Utah). The data was collected as part of a regional evaluation of paleoenvironmental conditions during...
Geochronological Data for: Geologic Map of the Emporia Quadrangle, North Carolina Geochronological Data for: Geologic Map of the Emporia Quadrangle, North Carolina
The Emporia 1:100,000-scale quadrangle straddles the Tidewater Fall Line in southern Virginia and includes a small part of northernmost North Carolina. Sediments of the coastal plain underlie the eastern three-fifths of this area. This data release contains geochronology from sediment samples collected in the eastern half of the Emporia 30’ x 60’ quadrangle, Virginia and North Carolina...
Nesting and non-nesting emergences for four species of imperiled sea turtles derived from acceleration data loggers, 2012-2017 Nesting and non-nesting emergences for four species of imperiled sea turtles derived from acceleration data loggers, 2012-2017
These data contain acceleration, pitch, yaw, roll, and ancillary data collected by acceleration data loggers (ADL) attached to four sea turtle species: green (Chelonia mydas) sea turtles, hawksbill (Eretmochelys imbricata) sea turtles, Kemp's ridley (Lepidochelys kempii) sea turtles, and loggerhead (Caretta caretta) sea turtles. A total of 54 nesting events and 76 non-nesting emergence...
Surficial geologic map database of the southeast 3/4 of the Las Vegas 1-degree by 2-degree quadrangle, southern Nevada: Contributions to the National Geologic Map Surficial geologic map database of the southeast 3/4 of the Las Vegas 1-degree by 2-degree quadrangle, southern Nevada: Contributions to the National Geologic Map
This data release presents geologic map data for the surficial geology of the Overton, Lake Mead, and Las Vegas 30-minute by 60-minute quadrangles, Arizona, Utah, and Nevada. This 1:100,000 scale geologic mapping incorporates new interpretive contributions and compilation from 1:24,000 to 1:250,000 scale published geologic map data sources. Geology incorporated from previous mapping has...
Meadow vole data for fragmentation study Meadow vole data for fragmentation study
The dataset contains observational records of encounters of meadow voles (Microtus pennsylvanicus) trapped at Eastern Ecological Science Center (formerly Patuxent Wildlife Research Center) in Laurel, Maryland, USA. Animals were trapped using Sherman traps from 23 September 1991 to 24 August 1993. Data collected included id, date, age, sex, weight, location and reproductive status.
