Data Releases
The data collected and the techniques used by USGS scientists should conform to or reference national and international standards and protocols if they exist and when they are relevant and appropriate. For datasets of a given type, and if national or international metadata standards exist, the data are indexed with metadata that facilitates access and integration.

Maps of water depth derived from satellite images of selected reaches of the American, Colorado, and Potomac Rivers acquired in 2020 and 2021 (ver. 2.0, September 2024) Maps of water depth derived from satellite images of selected reaches of the American, Colorado, and Potomac Rivers acquired in 2020 and 2021 (ver. 2.0, September 2024)
Information on water depth in river channels is important for a number of applications in water resource management but can be difficult to obtain via conventional field methods, particularly over large spatial extents and with the kind of frequency and regularity required to support monitoring programs. Remote sensing methods could provide a viable alternative means of mapping river...
Climate-Growth Analysis for Updated and Existing Tree-ring Network near Columbine Lake, Grand County, Colorado Climate-Growth Analysis for Updated and Existing Tree-ring Network near Columbine Lake, Grand County, Colorado
This data release is tree-ring data near Columbine Lake and surrounding region, Grand County, Colorado (Latitude 40.27˚ N, Longitude -105.83˚ E NAD83). Re-collection of four existing tree-ring sites (Hot Sulphur Springs Psuedotsuga menziessii (HSU), Lexan Creek Picea engelmannii (LCU), Monarch Lake Pinus ponderosa (MLU), and Vasquez Mountain Psuedotsuga menziessii (VMU)) was conducted to...
Insular mole skinks: Area of habitat still above water given projected sea level rise and proportion of habitat at risk of storm surge in the Florida Keys, Cedar Keys, and Egmont Key, Florida Insular mole skinks: Area of habitat still above water given projected sea level rise and proportion of habitat at risk of storm surge in the Florida Keys, Cedar Keys, and Egmont Key, Florida
The primary habitats for insular mole skinks in Florida are sand beaches, beach berms, and dunes, making them particularly vulnerable to sea level rise (SLR) and storm surge. We used the most recent SLR projections, high resolution lidar-based digital elevation models, a combination of a comprehensive land cover and hand-digitized aerial imagery, and the latest storm surge simulations to...
Observed occurrence of Eastern red-spotted newts (Notophthalmus viridescens) in the Northeastern United States Observed occurrence of Eastern red-spotted newts (Notophthalmus viridescens) in the Northeastern United States
This dataset includes surveys for the Eastern red-spotted newt (Notophrhalamus viridescens viridescen). The survey data includes 264 survey sites, landscape level covariates including human interference index, and landcover type, and survey level covariates including survey date and detection method.
Dissolved noble gas data and helium mass balance models for the Colorado and Virgin Rivers Dissolved noble gas data and helium mass balance models for the Colorado and Virgin Rivers
Dissolved noble gas data were collected using a portable mass spectrometer mounted on inflatable rafts on the Colorado River near Glenwood Springs, Colorado and the Virgin River near La Verkin, Utah. Data were collected approximately every 3 to 10 minutes for a suite of noble gases including helium (He), neon (Ne), argon (Ar), krypton (Kr), and xenon (Xe). Patterns in observed dissolved...
Maps of habitat suitability improvement potential for the Gunnison Sage-grouse (Centrocercus minimus) satellite populations in Southwestern Colorado Maps of habitat suitability improvement potential for the Gunnison Sage-grouse (Centrocercus minimus) satellite populations in Southwestern Colorado
Habitat restoration efforts to conserve wildlife species are often conducted along a range of local site conditions, with limited information available to gauge relative outcomes for habitat suitability among sites and identify those that may lead to the greatest returns on restoration investment. We leveraged existing resource selection function models to generate heatmaps of spatially...
