Pete Murdoch is a Research Hydrologist with the Watershed Research Group of the US Geological Survey in Troy, New York. Since 1982 he has lead research projects on watershed biogeochemical processes, and the effects of acid rain and climate change on aquatic systems. In the mid-1990s he served as the DOI representative to the White House Committee on Environmental and Natural Resources (CENR), and lead a pilot of a multi-agency collaborative assessment of the Delaware River based on the CENR 'Framework for Environmental Monitoring and Research". In 2004-06, Pete served as the DOI representative to an interagency committee that oversees the North American Carbon Program. He now is leading a multi-agency study on the effects of permafrost thawing on the hydrology, energy, and carbon budgets of the Yukon River Basin.
