Under the Arctic ice

When Colorado State University researcher Jessie Creamean first sent her GoPro down the five-foot hole through Arctic ice, she didn’t know if it would make it back up. 

At the beginning of the seven-week expedition, the water was blue and clear, and the GoPro returned intact from its trip . Creamean kept sending the GoPro down holes left from collecting ice cores throughout the expedition. At the end as the summertime settled in, the edges of the sea ice were often brown and the water was cloudy-green, meaning the algae and phytoplankton in the water and ice had started waking up and releasing into the ocean. 

Creamean and graduate student researcher Camille Mavis were part of an Arctic expedition aboard the ship Oden, a Swedish icebreaker specialized to move through ice-covered water.  When Creamean and Mavis returned from the field, they worked in the lab of University Distinguished Professor Sonia Kreidenweis to analyze samples at the Atmospheric Science department, part of the Walter Scott, Jr. College of Engineering.
