Dr. Derek Sjostrom
Adjuct UAA Department of Geological Sciences
Current Projects
Dr. Sjostrom is currently studying the stable isotope systematics of precipitation throughout the United States and south-central Alaska. Research projects in the planning stages include a sequence stratigraphy-based examination of forearc sediments exposed north of Anchorage, determination of stable isotope ratios of altered volcanic air fall deposits exposed on the Kenai Peninsula as an indicator of Tertiary paleoclimate, the potential modification of stream chemistry caused by changes in rock weathering brought about by climate modification, and nutrient cycling in soils in south-central Alaska. |

Dr. Lee Ann Munk
Current Projects
Dr. Munk conducts research in the field of environmental hydrogeochemistry in various regions in Alaska including the Anchorage Watershed, Prince William Sound, Katmai National Park, and the Western Arctic Parks.;The primary focus of the research is to develop models of the geochemical pathways of Potentially Toxic Metals in near surface environments and to characterize water resources. More recently Dr. Munk has also been utilizing stable isotopic compositions of water to model sources in the Anchorage Watershed.
