Dennis Darby

In April 2007, Dr. Dennis Darby attended and presented at the Iowa Academy of Science Annual Meeting held 27-29 April 2007 at Central College in Pella, Iowa. He was a guest at the Iowa Junior Academy of Science Awards Luncheon and the Iowa Academy of Science President's Dinner, after which he presented a talk titled "The Role of the Arctic Ocean in Global Climate Change?" Dr. Darby was on-hand at many different sessions at the Iowa Academy of Sciences Annual Meeting and was thrilled to meet and talk to many of the meeting participants.

Dr. Darby also presented a talk, "HOTRAX and the Effort to Unlock the Past Climatic Secrets of the Arctic," to approximately 100 chemistry students at Pella High School. Additionally, he spoke to six senior environmental science majors at Central College in Pella, IA.

Dennis Darby is Professor of Geological Oceanography in the Department of Ocean, Earth, and Atmospheric Sciences at Old Dominion University, where he has been since 1977. He earned his B.S. in 1966 and his M.S. in 1968, both in Geology, from the University of Pittsburgh and a Ph.D. in Geology and Oceanography in 1971 from the University of Wisconsin, Madison. His research focuses on the paleoclimatology and paleoceanography of the Arctic. Dr. Darby has served on a number of national committees and organizing groups, including the National Science Foundation's (NSF) Arctic System Science (ARCSS) Program Ocean-Atmosphere-Ice Interaction Science Steering Committee and the Arctic Program Planning Group of Joint Oceanographic Institutions for Deep Earth Sampling (JOIDES).

Dr. Darby recently led two successful coring expeditions to the central Arctic as part of the Healy-Oden Trans-Arctic Expedition (HOTRAX). This historic expedition, only the second crossing of the central Arctic by icebreakers, collected nearly 500 meters of sediment core and used multibeam swath mapping of the seafloor and chirp seismic to profile the sub-bottom in the upper 50 meters.
