Image of the Week: Investigating Life in and Under Arctic Sea Ice

Andy Juhl

Lamont-Doherty Earth Observatory marine ecologist Andy Juhl takes the temperature of a fresh core of sea ice during fieldwork near Barrow, Alaska in May 2013.

Each spring, large populations of algae grow in and just beneath Arctic sea ice. Juhl studies these communities to learn more about the different species that thrive in this frigid environment, the factors that control their growth and the role they play in the Arctic marine food web. Juhl’s work provides valuable baseline information about the relationship between sea ice and algae in the Arctic, and the region’s basic biological processes. The results of his research increase understanding of this important ecosystem and how it may be affected by climate-driven changes.
