Sarah Anderson teaches physics and aquatic science at Boerne High School in Boerne, Texas. She has twenty years of teaching experience including work as a classroom teacher, education specialist, and television instructor. In addition to her work in the classroom, Ms. Anderson conducts training for pre-service teachers and teaches a field-based aquatic science course for high school students during the summer. She has Bachelors and Masters degrees in Education and is currently pursuing a doctoral degree in Science Education.

Stephen Ackley has worked and conducted sea-ice research in Antarctica for more than 30 years. He previously worked with the Cold Regions Research and Engineering Laboratory (CRREL) and then joined the Department of Earth and Environmental Science at the University of Texas San Antonio in 2006. Ackley Point was named in Antarctica to honor Dr. Ackley for his outstanding sea-ice work in Antarctica by the U.S. Board on Geographic Names. Ackley Point is an ice covered point located near McMurdo Sound. Click here to find Ackley point on a map.

What were they doing?What were they doing?

The research team traveled by icebreaker to the Bellingshausen-Amundsen Sea in western Antarctica. During their two months at sea they sampled sea-ice properties such as temperature, snow depth, ice thickness, meteorological conditions, ice biogeochemistry, and biology in order to investigate sea-ice processes. The researchers deployed an array of 12-14 drifting buoys that will continue to measure these processes for an additional year. The research cruise was part of a larger coordinated program designed to estimate the exchange of salt, fresh water, and heat between the atmosphere and ocean, characterize the thickness and extent of sea ice, and determine if the sea ice is shrinking in this region. A cruise into the East Antarctic pack ice which took place at the same time will collect similar samples, and remote sensing studies will contribute additional observations before, during, and after the cruises.
