The response of Arctic sea ice to a warming climate includes decreases in extent, lower ice concentration, and reduced ice thickness. Summer melt seasons are lengthening with earlier melt onsets and later autumn freezeups. We believe this will likely lead to an increase in so-called “rotten ice” in the Arctic at the end of summer. This ice has experienced a long summer of melt, is fragile, difficult to work with, and has received little attention. Comprehensive information on its physical and microbiological properties does not exist. Our team is embarking on an ambitious field campaign in order to study this poorly-understood type of sea ice in the context of its microstructural properties and potential for habitability.
