Data Release for Geologic Map of the Pagosa Springs 7.5-minute quadrangle, Archuleta County, Colorado Data Release for Geologic Map of the Pagosa Springs 7.5-minute quadrangle, Archuleta County, Colorado
The Pagosa Springs geologic map is of the 7.5-minute quadrangle of the same name. It is located in southwestern Colorado, USA and shows the town of Pagosa Springs. The mapped area is southwest of the San Juan volcanic mountains (Oligocene) and north of the San Juan Basin. All bedrock units exposed in the map area are Upper Cretaceous in age except a minor canyon outcrop of Upper Jurassic...
Data release for estimating soil respiration in a subalpine landscape using point, terrain, climate and greenness data Data release for estimating soil respiration in a subalpine landscape using point, terrain, climate and greenness data
Landscape carbon (C) flux estimates are necessary for assessing the ability of terrestrial ecosystems to buffer further increases in anthropogenic carbon dioxide (CO2) emissions. Advances in remote sensing have allowed for coarse-scale estimates of gross primary productivity (GPP) (e.g., MODIS 17), yet efforts to assess spatial patterns in respiration lag behind those of GPP. Here, we...
Data release for Time series of high-resolution images enhances efforts to monitor post-fire condition and recovery, Waldo Canyon fire, Colorado, USA Data release for Time series of high-resolution images enhances efforts to monitor post-fire condition and recovery, Waldo Canyon fire, Colorado, USA
Interpretations of post-fire condition and rates of vegetation recovery can influence management priorities, actions, and perception of latent risks from landslides and floods. In this study, we used the Waldo Canyon fire (2012, Colorado Springs, Colorado, USA) as a case study to explore how a time series (2011-2016) of high-resolution images can be used to delineate burn extent and...
Data Release of Geologic Map of the north half of the Lake Walcott 30' x 60' Quadrangle, Idaho Data Release of Geologic Map of the north half of the Lake Walcott 30' x 60' Quadrangle, Idaho
The northern half of the Lake Walcott 30 x 60 minute quadrangle shows the geology of the southern part of the Craters of the Moon lava field, the complex geologic features of the Holocene Kings Bowl and Wapi lava fields, and the southern part of the Great Rift volcanic rift zone. The long extent and distribution of skylights in lava-tube systems of the Horse Butte and Wapi Park lava...
U-Pb SHRIMP zircon isotopic data for ages used on the Poncha Pass map U-Pb SHRIMP zircon isotopic data for ages used on the Poncha Pass map
U-Pb isotopic data from zircon measured using the SHRIMP-RG ion microprobe at Stanford University, CA. These data are used to calculate absolute ages of the samples from which the zircons were extracted. These samples are shown on the Poncha Pass map being submitted for publication (Minor, et al., in prep)
Data Release for Geologic Map of the Fort Collins 30' x 60' quadrangle, Larimer and Jackson Counties, Colorado, and Albany and Laramie Counties, Wyoming Data Release for Geologic Map of the Fort Collins 30' x 60' quadrangle, Larimer and Jackson Counties, Colorado, and Albany and Laramie Counties, Wyoming
This geologic map provides new and compiled geologic mapping at 1:100,000-scale in the Fort Collins 30' x 60' quadrangle covering the northern Front Range and adjacent areas of Colorado.
Data release of geospatial map database, argon geochronology and geochemistry data for: Geologic map of the San Antonio Mountain area, northern New Mexico and southern Colorado Data release of geospatial map database, argon geochronology and geochemistry data for: Geologic map of the San Antonio Mountain area, northern New Mexico and southern Colorado
This dataset accompanies publication "Geologic map of the San Antonio Mountain area, northern New Mexico and southern Colorado". Data presented here include the digital geologic database, 40Ar/39Ar geochronology and major and trace element chemistry from lava flows and an ignimbrite. The geologic database includes spatial feature classes and non-spatial tables that collectively contain...
Data release of geospatial map database and structural measurements for: Geologic map of the Osage SW 7.5' quadrangle, Newton, Madison, and Carroll counties, Arkansas Data release of geospatial map database and structural measurements for: Geologic map of the Osage SW 7.5' quadrangle, Newton, Madison, and Carroll counties, Arkansas
This dataset accompanies publication "Geologic map of the Osage SW 7.5' quadrangle, Newton, Madison, and Carroll counties, Arkansas". Data presented here include the digital geologic database and structural measurements including joints, deformation bands, and small faults collected during field investigation. These data support the following publication: Turner, K.J., and Hudson, M.R...
Data release for the Historical land use and land cover for assessing the northern Colorado Front Range urban landscape Data release for the Historical land use and land cover for assessing the northern Colorado Front Range urban landscape
The dataset was generated to describe historical land-use and land-cover (LULC)for the northern Colorado urban Front Range (which includes the cities of Boulder, Fort Collins, Greeley, and Denver) for an area covering approximately 1,023,660 hectares. The Front Range urban landscape is diverse and interspersed with highly productive agriculture as well as natural land cover types...
Data release for Applying high-resolution imagery to evaluate restoration-induced changes in stream condition, Missouri River Headwaters Basin, Montana Data release for Applying high-resolution imagery to evaluate restoration-induced changes in stream condition, Missouri River Headwaters Basin, Montana
Degradation of streams and associated riparian habitat across the Missouri River Headwaters Basin has motivated several stream restoration projects across the watershed. Many of these projects install a series of beaver dam analogues (BDAs) to aggrade incised streams, elevate local water tables, and create natural surface water storage by reconnecting streams with their floodplains...
Data release for Lake levels in a discontinuous permafrost landscape: Late Holocene variations inferred from sediment oxygen isotopes, Yukon Flats, Alaska Data release for Lake levels in a discontinuous permafrost landscape: Late Holocene variations inferred from sediment oxygen isotopes, Yukon Flats, Alaska
During recent decades, lake levels in the Yukon Flats region of interior Alaska have fluctuated dramatically. However, prior to recorded observations, no data are available to indicate if similar or more extreme variations occurred during past centuries and millennia. This study explores the history of Yukon Flats lake origins and lake levels for the past approximately 5,500 years from...
