Isotopes in North American Rocky Mountain Snowpack 1993-2014
By Lesleigh Anderson (GECSC), Max Berkelhammer, and Alisa Mast. Published in Quaternary Science Reviews.
This report documents isotopic ratios in Rocky Mountain snowpack. Changes in snowpack and water resources have significant impacts on alpine ecosystems, and it is important to understand their response to climate forcing such as temperature and dominant storm trajectories. A process-based understanding of climate-snowpack relationships from networks such as the Isotopes in Rocky Mountain Snowpack network facilitates interpretation of long-term patterns of snowpack and temperature from paleoclimate proxy records.

U.S. Geological Survey Unmanned Aircraft Systems (UAS) Roadmap 2014
By Jill Cress, Mike Hutt, Jeff Sloan, Mark Bauer, Mark Feller, and Susan Goplen. USGS Open-File Report 2015-1032.
The National Unmanned Aircraft Systems (UAS) Project Office, located in Denver as part of the Geosciences and Environmental Change Science Center, has been a key player in performing research on and operational studies of this emerging data-collection technology. UAS have been found to be more cost-effective, safer, and better platforms for studying climate and landscape changes, conducting wildlife inventories, and supporting land management missions than traditional methods. This report provides an overview of the technology, procedures, and lessons learned from missions conducted by U.S. Department of the Interior agencies and describes strategic actions that the Department could take in order to fully utilize this technology going forward.

Linking social values and ecosystem services: Social-ecological hotspots for public lands management
By Ken Bagstad (GECSC), James Reed, Darius Semmens (GECSC), Ben Sherrouse (GECSC), and Austin Troy. Published in Regional Environmental Change.
In this paper, hot and cold spots for perceived and modeled ecosystem services were mapped by synthesizing results from a social-values mapping study of residents living near the Pike-San Isabel National Forest, located in the Southern Rocky Mountains, with corresponding biophysically modeled ecosystem services. The goal was to determine whether publicly valued locations for aesthetic, biodiversity, and life-sustaining values relate meaningfully to results from corresponding biophysical ecosystem service models. The study found weak relationships between perceived and biophysically modeled services, indicating that public perception of ecosystem service provisioning regions is limited. Biophysical and cultural ecosystem services hotspot maps for ecosystem services may provide more useful information for forest planning when combined than alone.
