U-Pb zircon data for: The Poncha Pass and Deadman Creek areas, northern Sangre de Cristo Mountains of south-central Colorado

Geologic mapping, characterization of geologic structures, and sampling for geochronology was completed in two areas of the northwestern Sangre de Cristo Mountains from 2011 through 2017. This data release provides the raw analytical data, metadata and sample information for 20 zircon U-Pb age analy

Grand Mesa 2017-02-01 snow depth estimate

Elevation difference (snow depth estimate for exposed ground surfaces) between co-registered WorldView-3 optical stereo DSM products from 2016-09-25 (snow-off) and 2017-02-01 (snow-on). These are preliminary products from the Stereo2SWE workflow, used to derive snow depth estimates from time series

Vaccine driven virulence evolution: Consequences of unbalanced reductions in mortality and transmission and implications for pertussis vaccines

Many vaccines have heterogenous effects across individuals. Additionally, some vaccines do not prevent infection, but reduce disease-associated mortality and transmission. Both of these factors will alter selection pressures on pathogens, and thus shape the evolution of pathogen virulence. We use a

Identifying geochemical hot moments and their controls on a contaminated river floodplain system using wavelet and entropy approaches, Environmental modelling & software: Dataset

We used entropy and wavelet techniques to identify temporal variability in geochemical constituents and their controls along three transects within a contaminated floodplain system near Rifle CO. The objectives of this study were to: (1) identify hot moments of conservative and redox sensitive speci

Fungal symbionts alter plant responses to global change

While direct plant responses to global change have been well characterized, indirect plant responses to global change, via altered species interactions, have received less attention. Here, we examined how plants associated with four classes of fungal symbionts (class I leaf endophytes [EF], arbuscul

Opitions for the Rocky Mountain Compact and the State of Colorado for Low-Level Radioactive Waste Disposal in 1989 and post 1992

The Rocky Mountain Compact consists of four states — Colorado, Nevada, New Mexico and Wyoming. While a low-level radioactive waste site is currently in operation in Nevada, it is scheduled to close by December 31, 1992. Colorado has been designated by the Compact as the next host state to develop a
