Mapped fire perimeters from the Sky Island Mountains of US and Mexico: 1985-2017 Mapped fire perimeters from the Sky Island Mountains of US and Mexico: 1985-2017
Polygon locations of fire perimeters in the Sky Island mountain ranges in the Madrean Archipelago Ecoregion of the southwestern United States and northern Mexico. These fires occurred from 1985 to 2017 and were mapped using Landsat satellite imagery.
Differenced Normalized Burn Ratio (dNBR) data of wildfires in the Sky Island Mountains of the southwestern US and northern Mexico from 2011-2017 Differenced Normalized Burn Ratio (dNBR) data of wildfires in the Sky Island Mountains of the southwestern US and northern Mexico from 2011-2017
This dataset is composed of 97 Differenced Normalized Burn Ratio (dNBR) images. Each dNBR represents a rough measure of fire-related vegetation change for wildfires (>400 ha) that occurred in the Sky Island Mountains within the Madrean Archipelago Ecoregion of the United States and Northern Mexico. These fires occurred between 2011 and 2017 and were mapped using Landsat 7 and 8 satellite...
Identify sources of high E. coli concentrations, beaches of southern Lake Michigan, 2015, (version 2.0, July 2020) Identify sources of high E. coli concentrations, beaches of southern Lake Michigan, 2015, (version 2.0, July 2020)
Data were collected as part of a study to identify sources of E. coli contamination at several beaches located in the Grand Calumet River Areas of Concern, located in northern Indiana on Lake Michigan. Water samples were collected at each site (Jeorse Park 1, Jeorse Park 2, Hammond East, Hammond West, Whihala East, and the Grand Calumet River) three times a week for thirteen weeks and...
Precipitation and acoustic monitoring results associated with Arizona 1 and Pinenut uranium mines collected 2015-2016 Precipitation and acoustic monitoring results associated with Arizona 1 and Pinenut uranium mines collected 2015-2016
Acoustic monitoring stations were comprised of Wildlife Acoustics SMBAT2+ bat detectors powered by a 6v 36 AH (Powersonic, Model PS-6062NB) external battery and charged by a 6v solar panel (Brunton Solarflat) with a 6/12 voltage regulator (Rogue Engineering Inc.). Detectors were programmed to turn on at 1800 hours and monitor continuously throughout the night when triggered automatically...
Organic petrographic evaluation of carbonaceous material in sediments of the Kinnickinnic River, Milwaukee, WI, U.S.A. Organic petrographic evaluation of carbonaceous material in sediments of the Kinnickinnic River, Milwaukee, WI, U.S.A.
This study describes the application of organic petrology techniques to quantify the amount of coal and carbonaceous combustion by-products (i.e., coke, coal tar/pitch, cenospheres) in sediments taken from the Kinnickinnic River adjacent to the former site of the Milwaukee Solvay Coke and Gas Company. The site produced metallurgical coke and coal-gasification by-products from 1902-1983...
Data release: A large-scale database of modeled contemporary and future water temperature data for 10,774 Michigan, Minnesota and Wisconsin Lakes Data release: A large-scale database of modeled contemporary and future water temperature data for 10,774 Michigan, Minnesota and Wisconsin Lakes
Climate change has been shown to influence lake temperatures globally. To better understand the diversity of lake responses to climate change and give managers tools to manage individual lakes, we modelled daily water temperature profiles for 10,774 lakes in Michigan, Minnesota and Wisconsin for contemporary (1979-2015) and future (2020-2040 and 2080-2100) time periods with climate...
Data used to model and map pH and redox conditions in the Northern Atlantic Coastal Plain aquifer system, eastern USA Data used to model and map pH and redox conditions in the Northern Atlantic Coastal Plain aquifer system, eastern USA
Data used to model and map pH and redox conditions in groundwater in the Northern Atlantic Coastal Plain aquifer system, eastern USA, are documented in this data release. The models use as input data measurements of pH and dissolved oxygen concentrations at about 3000 to 5000 wells, which were compiled primarily from U.S. Geological Survey and U.S. Environmental Protection Agency...
Low-altitude aerial imagery from unmanned aerial systems (UAS) at select locations over the Potomac River, October 2019 Low-altitude aerial imagery from unmanned aerial systems (UAS) at select locations over the Potomac River, October 2019
These digital images were taken at select locations over the Potomac River using 3DR Solo unmanned aircraft systems (UAS) in October 2019. These images were collected for the purpose of evaluating UAS assessment of river habitat data such as water depth, substrate type, and water clarity. Each UAS was equipped with a Ricoh GRII digital camera for natural color photos, used to produce...
Lake Trout Otolith Growth Increment Measurements, Lake Clark National Park and Preserve, Alaska, 1979-2012 Lake Trout Otolith Growth Increment Measurements, Lake Clark National Park and Preserve, Alaska, 1979-2012
his data set documents the width of annual otolith growth increments from Lake Trout collected in lakes within Lake Clark National Park and Preserve, Alaska. The analysis of this data was published in von Biela et al. 2020 (DOI: 10.1111/eff.12566)
2004-2010 Chesapeake Bay Smallmouth and Largemouth Bass Estrogenic Biomarker Data 2004-2010 Chesapeake Bay Smallmouth and Largemouth Bass Estrogenic Biomarker Data
The data was gathered to document the extent and severity of biomarkers of exposure to estrogenic chemicals in smallmouth and largemouth bass. Samples were collected from 2004 through 2010 at sites in five watersheds within the Chesapeake Bay watershed. A total of 281 largemouth bass were collected from the Potomac, Susquehanna, Patuxent and Rappahannock rivers and 1,384 smallmouth bass...
Lava level and crater geometry data during the 2018 lava lake draining at Kilauea Volcano, Hawaii Lava level and crater geometry data during the 2018 lava lake draining at Kilauea Volcano, Hawaii
In May 2018, the onset of new eruptive activity on the lower flank of Kīlauea Volcano, Hawaiʻi, accompanied the draining of the lava lake at the summit, 40 km upslope. The lava lake draining lasted over seven days, and transitioned into the largest collapse event at the summit of Kīlauea in over 200 years, with the paired flank and summit activity marking a historic episode in the modern...
