Oceanographer simulates Arctic sea ice to learn more about greenhouse gases
University of Rhode Island oceanographer Brice Loose is nearing completion of a two-month experiment inside a laboratory where the temperature is a frosty -20 degrees Fahrenheit to reproduce the surface of the frozen Arctic Ocean and learn what factors influence the exchange of gases between the water and atmosphere.
“The polar regions are very important areas for gas uptake by the ocean because the surface water there gets pulled down to the deep ocean,” said Loose, an assistant professor at the URI Graduate School of Oceanography. “But sea ice can act as a barrier to the exchange of gases between ocean and atmosphere, so we’re trying to figure out exactly how much exchange you get. The ice creates a huge wake behind it...
