An observational and modeling study of impacts of bark beetle-caused tree mortality on surface energy and hydrological cycles

Publications Posted on: October 06, 2015
Bark beetle outbreaks have killed billions of trees and affected millions of hectares of forest during recent decades. The objective of this study was to quantify responses of surface energy and hydrologic fluxes 2-3 yr following a spruce beetle outbreak using measurements and modeling.

Spatial and temporal patterns in water chemistry of two high elevation lakes in southeast Wyoming

Publications Posted on: May 28, 2015
The Glacier Lakes Ecosystem Experiments Site (GLEES) was established to examine the effects of atmospheric deposition and climate change on alpine and subalpine ecosystems. The site contains East Glacier Lake (3282 m elevation) and West Glacier Lake (3276 m elevation), and their watersheds. These two small lakes are located 120m from each other at the alpine/subalpine transition.

Wind and ecosystem response at the GLEES

Publications Posted on: May 28, 2015
Research was conducted to determine wind patterns and snow deposition at a high elevation alpine/subalpine ecotone site using deformation response of trees to prevailing winds. The research has provided detailed maps of wind speed, wind direction, and snow depth as determined from tree deformation. The effects of prevailing wind on tree blowdown at the site have also been described.

Comparison of estimates of snow input to a small alpine watershed

Publications Posted on: May 28, 2015
We have used five methods to estimate the snow water equivalent input to the Glacier Lakes Ecosystem Experiments Site (GLEES) in south-central Wyoming during the winter 1987-1988 and to obtain an estimate of the errors. The methods are: (1) the Martinec and Rango degree-day method; (2) Wooldridge et al.

Using wind-deformed conifers to measure wind patterns in alpine transition at GLEES

Publications Posted on: May 28, 2015
The Glacier Lakes Ecosystem Experiments Site (GLEES) is a high-elevation ecosystem in the Snowy Range west of Laramie, WY, that is perceived to be highly sensitive to changes in chemical and physical climate. Deposition of atmospheric chemicals to this ecosystem is, in part, governed by the wind pattern. The GLEES has numerous wind-swept areas where the coniferous vegetation growth pattern is characteristically wind deformed or krummholz.
