Hansell Chairing Carbon Cycle Science Steering Committee of the U.S. Global Change Research Program

Dennis Hansell

MIAMI — March 17, 2011 — Dennis Arthur Hansell was named chair of the U.S. Global Change Research Program’s Carbon Cycle Scientific Steering Group (CCSSG). The group consists of national experts involved in carbon cycle research and application from federal, state, university, and non-governmental organizations.

Hansell is a professor and former division chair of Marine and Atmospheric Chemistry at the University of Miami (UM) Rosenstiel School of Marine & Atmospheric Science. His primary research focus is on the cycling of carbon through marine dissolved organic matter. Hansell’s work in the open ocean and on polar seas has been published in over 80 peer-reviewed scientific journal articles. He has served on numerous national and international committees responsible for the advancement of ocean science. Hansell received his Ph.D. in oceanography at the University of Alaska-Fairbanks and an M.S. in Fisheries Science from Auburn University.

“This diverse group of scientists brings together multi-disciplinary viewpoints that are helping us shape research advancements in this critical field,” said Hansell. “Carbon plays a central role in our changing climate, as it is being released to the atmosphere in great quantities as carbon dioxide and methane, two major greenhouse gases. As scientists, we seek to improve our predictive understanding of its movements and transformations through the major earth systems, including the oceans, the atmosphere and land. Our team also considers the human dimensions of the carbon cycle; our decisions as a society affect the carbon cycle in fundamental ways, and these impact our climate. ”

The function of the CCSSG is to provide individual as well as broad scientific and application input to the U.S. Carbon Cycle Interagency Working Group, responsible for federal support of the research, as it develops and administers carbon cycle science programs. Hansell and members of the CCSSG provide input on the direction of scientific content and its relevance to various stakeholder communities, identifying gaps and potential new areas of research.
