Baseline High Resolution Land Cover Map for the Mainstem Klamath River Corridor Downstream of Iron Gate Dam, Klamath River, CA, 2018 Baseline High Resolution Land Cover Map for the Mainstem Klamath River Corridor Downstream of Iron Gate Dam, Klamath River, CA, 2018
This data release includes a file geodatabase with land cover maps for a 313-kilometer segment along the mainstem Klamath River corridor downstream from Iron Gate Dam, CA. The maps were derived from high-resolution (15cm) imagery and topobathymetric elevation data, collected by NV5 Geospatial (formerly QSI, Inc) and published on Open Topography (https://doi.org/10.5069/G9DN436N)...
Habitat and biological assemblage data of streams within Tribal lands of the Pearl River Community of the Mississippi Band of Choctaw Indians, 2017-18 Habitat and biological assemblage data of streams within Tribal lands of the Pearl River Community of the Mississippi Band of Choctaw Indians, 2017-18
This data release contains habitat survey data (quantitative and qualitative) and biological assemblage data (periphyton, macroinvertebrate, and fish) collected among 8 stream sites within the Tribal lands of the Pearl River Community of the Mississippi Band of Choctaw Indians (MBCI). The MBCI is a Federally recognized Native American Tribe and the Pearl River Community, located near...
Bathymetry, Stage-Area, and Stage-Volume Tables for the Calaveras Reservoir, California, 2019 (ver. 2.0, March 2025) Bathymetry, Stage-Area, and Stage-Volume Tables for the Calaveras Reservoir, California, 2019 (ver. 2.0, March 2025)
Dataset contains reservoir bathymetry and shoreline topography up to dam crest elevation. Data were collected using small uncrewed aerial system (sUAS), multibeam sonar, and terrestrial lidar. Version 2.0 The multibeam sonar & terrestrial lidar data in version 2 was reprocessed for higher accuracy. 1-meter lidar data for 2020 from the USGS 3DEP program was used around the shoreline of...
High-resolution bathymetry and backscatter data collected near the Stamp Sands of Lake Superior in 2021 High-resolution bathymetry and backscatter data collected near the Stamp Sands of Lake Superior in 2021
The erosion and active transport of legacy mine tailings (called “stamp sands”) are impacting native fish species and aquatic habitats on a shallow water rocky reef complex along the Keweenaw Peninsula of Michigan called Buffalo Reef. Stamp sands are spreading from an old mill site at the Town of Gay and settling on the reef. Multiple surveys have documented the underwater migration of...
Digital database of the previously published geomorphic-structural map of the Ouachita Mountains Digital database of the previously published geomorphic-structural map of the Ouachita Mountains
The Ouachita Mountains record the late Paleozoic Laurentia-Gondwana orogenic event along southern Paleo-North America during Pangea supercontinent formation. This data release contains a digital compilation of geomorphic-structural information from the Ouachita Mountains of southeastern Oklahoma and southwestern Arkansas as previously published by Arbenz (2008). The geodatabase...
40Ar/39Ar data from the Janub Metamorphic Complex, Southern Jordan 40Ar/39Ar data from the Janub Metamorphic Complex, Southern Jordan
This data release includes 40Ar/39Ar collected at the U.S. Geological Survey for samples from the Janub Metamorphic Complex in Southern Jordan. Rock samples were collected by Hind Ghanem of the University of Jordan. Muscovite-rich microcores were drilled from a polished thick section of a deformed granitoid and analyzed by argon geochronology at the U.S. Geological Survey Bascom ARgon...
