Subaerially exposed river sand and reservoir shoreline modelling for Lake Powell releases and changes in Lake Powell and Lake Mead storage Subaerially exposed river sand and reservoir shoreline modelling for Lake Powell releases and changes in Lake Powell and Lake Mead storage
These data were compiled to evaluate impacts of different reservoir management scenarios on sand exposure for aeolian landscape and cultural site resources. Objective of our study was to predict areas of dry, bare Colorado River sand as a function of different management alternative scenarios. These data represent predictions of dry, bare sand for the reach of the Colorado River between...
Sulfur dioxide emission rates from Hawaiian volcanoes, 2018-2022 Sulfur dioxide emission rates from Hawaiian volcanoes, 2018-2022
Measurement of sulfur dioxide (SO2) emission rates is a critical aspect of monitoring and studying active volcanoes. Changes in emission rate are often associated with changes in volcanic activity and in some cases may herald future changes in activity. At the Hawaiian Volcano Observatory (HVO), emission rates of SO2 from Hawaiian volcanoes have been measured by ultraviolet spectrometer...
Sulfur dioxide emission rates from Kīlauea Volcano, Hawaii, 2008-2013 Sulfur dioxide emission rates from Kīlauea Volcano, Hawaii, 2008-2013
Kīlauea Volcano on the Island of Hawai‘i was in a state of nearly continuous eruption from 1983 - 2018. Large amounts of sulfur dioxide gas (SO2) were released from the volcano’s East Rift Zone (ERZ) during the entire eruptive period, and from the Overlook vent at the summit of the volcano from 2008-2018. This data release presents ground-based estimates of SO2 emission rates from the...
Summary of Detection Data for Breeding Common Loons in North-central Minnesota (2023) Summary of Detection Data for Breeding Common Loons in North-central Minnesota (2023)
The Deepwater Horizon oil spill caused extensive injury to natural resources in the Gulf of Mexico, and Gavia immer (common loon) were negatively affected from the spill. The Open Ocean Trustee Implementation Group funded the project Restoration of Common Loons in Minnesota to restore common loons lost to the spill. In 2020–21, study lakes in an eight-county region in north-central...
Summary of Responses at the 2021 Colorado River Basin Science and Technology Meetings Summary of Responses at the 2021 Colorado River Basin Science and Technology Meetings
In June and July 2021, the Colorado River Basin Actionable and Strategic Integrated Science and Technology (ASIST) pilot team held a series of 12 Science and Technology Collaboration meetings with U.S. Geological Survey science staff to discuss complex integrated science challenges and solutions related to drought in the Colorado River Basin. These meetings were structured to explore...
Summary of Selected Basin and Streamflow Special Conditions for USGS Streamgages in Alaska Summary of Selected Basin and Streamflow Special Conditions for USGS Streamgages in Alaska
This dataset summarizes selected basin and streamflow special conditions for USGS streamgages in Alaska that are commonly used for site and period of record selection for regional analyses, through water year 2022. The data consist of a table providing information about the type of streamflow available for the site, site special conditions related to the timing of data collection, basin...
Summary Simulated Groundwater-transported Nitrogen Loads on the North Shore of Long Island Sound and Associated Data Summary Simulated Groundwater-transported Nitrogen Loads on the North Shore of Long Island Sound and Associated Data
A monthly model of groundwater-transported nitrogen loads was developed for 12-digit hydrologic unit code (HUC12) watersheds on the north shore of Long Island Sound in coastal Connecticut and adjacent areas of New York and Rhode Island. As part of the analysis, potential management actions that upgraded septic systems or reduced fertilizer application to areas of turf-grass were also...
Summer Roost Site Suitability Analyses of Four North American Bat Species in the Eastern United States Summer Roost Site Suitability Analyses of Four North American Bat Species in the Eastern United States
This data release contains the spatial raster outputs from analyses of summer roost site habitat for each of 4 species considered under the United States Forest Service proposed Bat Conservation Strategy (Myotis lucifugus, MYLU; Myotis septentrionalis, MYSE; Myotis sodalis, MYSO; and Perimyotis subflavus, PESU). The included raster data represent the mean suitability for summer roosting...
Supplemental groundwater level, spring flow, and streamflow data for the Water Resources Inventory of the Las Cienegas National Conservation Area, Southeastern Arizona Supplemental groundwater level, spring flow, and streamflow data for the Water Resources Inventory of the Las Cienegas National Conservation Area, Southeastern Arizona
This data release contains hydrologic datasets used in U.S. Geological Survey Scientific-Investigations Report 2023-XXXX that are not available from other sources such as the National Water Information System (NWIS). The hydrologic datasets include groundwater levels, spring and stream discharge measurements, and lengths of perennial streamflow reaches, collected within the Las Cienegas...
Supplemental Results from: Using mobile acoustic monitoring and false-positive N-mixture models to estimate bat abundance and population trends Supplemental Results from: Using mobile acoustic monitoring and false-positive N-mixture models to estimate bat abundance and population trends
These data contain the supplementary results corresponding with the journal article: Using mobile acoustic monitoring and false-positive N-mixture models to estimate bat abundance and population trends by Udell et al. (2024) in Ecological Monographs. These results contain the findings from the North American Bat Monitoring Program's (NABat) "Summer Abundance Status and Trends" analyses...
Supplementary data in support of oceanographic and water quality times-series measurements made at Thompsons Beach and Stone Harbor, NJ from September 2018 to February 2023 Supplementary data in support of oceanographic and water quality times-series measurements made at Thompsons Beach and Stone Harbor, NJ from September 2018 to February 2023
In 2012, Hurricane Sandy struck the Northeastern US causing devastation among coastal ecosystems. Post-hurricane marsh restoration efforts have included sediment deposition, planting of vegetation, and restoring tidal hydrology. The work presented here is part of a larger project funded by the National Fish and Wildlife Foundation (NFWF) to monitor the post-restoration ecological...
