Stephen Ackley was a sea ice geophysicist and branch chief, when he was at the U.S. Army Cold Regions Research and Engineering Laboratory (CRREL) for approximately 30 years, until 1999. He joined the research group at the Laboratory for Remote Sensing and Geoinformatics (LRSG) in the Department of Geological Sciences at UTSA in 2006. Professor Ackley has been the co-chairman of the Scientific Committee on Antarctic Research (SCAR) program on Antarctic Sea Ice Processes and Climate (ASPeCt) ) and chaired the Science Steering Group for the Autosub-Under-Ice program which developed and used an Autonomous Underwater Vehicle to make the first AUV trips under sea ice in the Arctic and the Fimbul Ice Shelf in the Antarctic. He was the Arctic Chair recipient at the Naval Postgraduate School in 1985-6. He held a joint appointment at Dartmouth College (Thayer School of Engr) as Adj Asst Prof and Adj Assoc Prof during his research career at the Cold Regions Research and Engr Lab. During this period, he was the co-founder of the joint program in Cold Regions Science and Engr and has supervised or served on the graduate thesis committees for students at Dartmouth College, Univ of NH, Univ of Southern Cal., Naval Postgraduate School, Open University(UK), Univ. of Tasmania(Australia) and now at UTSA. He has been the recipient of peer-reviewed research grants from the US National Science Foundation since 1976, and from NSF, NASA, and ONR while at UTSA, for research on Antarctic and Arctic sea ice. This research has been conducted by him during twelve research cruises on several nations’ icebreakers into the sea ice zone surrounding Antarctica and on the first Antarctic sea ice drifting station, Ice Station Weddell (1992). Since his arrival at UTSA, students and faculty have participated in over 10 expeditions to the Arctic, Antarctic and a Mexican glacier under his leadership. His co-authored monograph on the Growth Structure and Properties of Sea Ice is extensively used internationally as introductory review text and reference source material for graduate students in Polar Marine Sciences. He was the founding Chairman and is on the continuing organizing committee of the Gordon Research Conferences on Polar Marine Science. These seven conferences, held biannually, have provided regular reviews of cutting-edge research in Polar Marine Science.


He was awarded the National Science Foundation’s Antarctic Service Medal for service in Antarctica. Ackley Point at the Ross Island, Antarctica was named in honor of his outstanding sea ice research in Antarctica by the U.S. Board on Geographic Names.
