My research interests are inspired by the need to understand the effects of our modern society on arctic ecosystems and to apply that understanding to the sustainable use of these ecosystems. One current focus involves multi-disciplinary environmental studies linking marine and freshwater environments to understand how they interact and the effect of anthropogenic stressors on these systems. This work links traditional oceanographic studies with critical environmental concerns represented by a developing field termed environmental oceanography. Critical environmental challenges face arctic aquatic ecosystems from long-range transport of contaminants, resource development pressures, population growth, and climate change. Good science can inform and assess environmental and resource management protection strategies.
Radioecology is another interest. I have done surveys at the Project Chariot and Amchitka underground nuclear test site in Alaska. Dr. John Kelley and I have established a UAF ESTES and SFOS gamma spectroscopy laboratory for environmental radioactivity studies. In 2012 this laboratory will complete quality assurance quality control development to support gamma counting of Cesium-137 and Lead-210 for sediment core dating application.
