Lidar data for natural release experiment at the USGS Debris Flow Flume 17 May 2017 Lidar data for natural release experiment at the USGS Debris Flow Flume 17 May 2017
Lidar data were collected on 17 May 2017 at the USGS debris-flow flume (44.215, -122.254) to monitor the movement of a constructed landslide experiment. A static prism of sediment was emplaced behind a retaining wall at the top of the flume. Water was added via sprinklers to the surface and also via pipes to the subsurface, in order to saturate the sediment mass. The sediment mass...
Quality Assurance of Water Level Records from Wells in the Mississippi River Valley Alluvial Aquifer in Missouri from the Missouri Department of Natural Resource's Well Information Management System (WIMS) Quality Assurance of Water Level Records from Wells in the Mississippi River Valley Alluvial Aquifer in Missouri from the Missouri Department of Natural Resource's Well Information Management System (WIMS)
The Missouri Department of Natural Resources' (MoDNR) Well Information Management System (WIMS) is a repository for recent (1983-present) well information that includes date of completion, well construction, geology, and water level. Well information is provided by the well drillers during the permitting process and is updated regularly by MoDNR. This data set consists of well records...
Global Geochemical Database for Critical Minerals in Archived Mine Samples Global Geochemical Database for Critical Minerals in Archived Mine Samples
The Critical Minerals in Archived Mine Samples Database (CMDB) contains chemistry and geologic information for historic ore and ore-related rock samples from mineral deposits in the United States. In addition, the database contains samples from archetypal deposits from 27 other countries in North America, South America, Asia, Africa and Europe. Samples were obtained from archived ore...
Physico-chemical characteristics and sediment and nutrient fluxes of floodplains, streambanks, and streambeds in the Chesapeake Bay and Delaware River watersheds Physico-chemical characteristics and sediment and nutrient fluxes of floodplains, streambanks, and streambeds in the Chesapeake Bay and Delaware River watersheds
Dataset includes site averages of measurements of floodplain and streambank sediment physico-chemistry and long-term (dendrogeomorphic) vertical and lateral geomorphic change, and reach scale floodplain width, streambank height, channel width, and streambed particle size. This information was used to calculate fluxes of sediment, fine sediment, sediment-C, sediment-N, and sediment-C of...

Ecosphere 10(10):e02907. 10.1002/ecs2.2907. It includes one data set with physicochemical and biological data from 40 stream sites (100 m length) in the Wyoming Range for summer 2016.
Reproductive Physiology of Brown Pelican Along the Coast of Alabama, 2017-2018 Reproductive Physiology of Brown Pelican Along the Coast of Alabama, 2017-2018
The datasets stored in this folder summarize reproductive data for Brown Pelicans nesting on Gaillard and Cat Islands, Alabama, in 2017 and 2018. Data include nest and nestling survival, nest site characteristics, environmental covariates, and temperatures recorded inside nests.
Inventory map of submarine and subaerial-to-submarine landslides in Glacier Bay, Glacier Bay National Park and Preserve, Alaska Inventory map of submarine and subaerial-to-submarine landslides in Glacier Bay, Glacier Bay National Park and Preserve, Alaska
Mass-wasting events that displace water, whether they initiate from underwater sources (submarine landslides) or subaerial sources (subaerial-to-submarine landslides), have the potential to cause tsunami waves that can pose a significant threat to human life and infrastructure in coastal areas (for example towns, cruise ships, bridges, oil platforms, and communication lines). Sheltered...
Argon data for Amazon Craton Argon data for Amazon Craton
This dataset accompanies planned publication 'Genesis of early Neoproterozoic gold deposits, southwestern Amazon Craton, western Brazil'. The Ar/Ar data is for samples that record the mineralization of the area. The geochronology provides time constraints for the mineralization studied in the manuscript. Samples were collected from the Amazon Craton region, and collection was done by...
Argon data for Central Andes (Domeyko Range, Chile) Argon data for Central Andes (Domeyko Range, Chile)
This dataset accompanies planned publication 'Gondwanan inheritance on the building of the western Central Andes (Domeyko Range, Chile): Structural and thermochronological approach (U-Pb and 40Ar-39Ar)'. The Ar/Ar data is for samples that record the sedimentation of the area. The geochronology provides time constraints for the sedimentation studied in the manuscript. Samples were...
Fractional estimates of exotic annual grass cover in dryland ecosystems of western United States (2016 - 2019) Fractional estimates of exotic annual grass cover in dryland ecosystems of western United States (2016 - 2019)
The dryland ecosystems of the western United States have been invaded by exotic annual grasses, such as cheatgrass (Bromus tectorum L.), that has promoted increased fire activity and reduced biodiversity detrimental to socio-environmental systems. The use of remote sensing tools to monitor exotic annual grass cover and dynamics over large areas can support early detection and rapid...
Sediment toxicity test endpoints from the U.S. Geological Survey 2014 Southeast Regional Stream Quality Assessment Sediment toxicity test endpoints from the U.S. Geological Survey 2014 Southeast Regional Stream Quality Assessment
These data present the results of sediment toxicity tests conducted by the US Geological Survey's Columbia Environmental Research Center (CERC) in Columbia, MO, in 2014. The sediments were collected as one part of a larger study on stream quality in Southeastern USA streams during the summer of 2014. For more information on the larger study see- https://webapps.usgs.gov/rsqa. The data...
