Since July of 1985, Penn State scientists have been cooperating with investigators from other universities in several ecosystem studies at an existing Department of Energy (DOE) study site on the North Slope of Alaska. The primary focus of the REFLEX program is to test new applications of remote sensing systems and allied digital database processing techniques for studying hydrologic/ecologic interactions. One of the goals of this particular REFLEX project was to complement ongoing R4D studies near Toolik Lake. Since their initial cooperative efforts with R4D investigators at the R4D study site in Phase I, scientists (primarily G. Petersen and B. Evans), have been intimately involved with the Landscape Ecology Working Group, one of several such groups established within the R4D program. As part of the R4D program, the Landscape Ecology Working Group is focusing on landscape-scale patterns and interactions that have applications to long slopes, watersheds, and large regions of the Alaskan North Slope.
