Highlight: “These data are critical for understanding how climate-induced changes in the timing of migratory herbivore grazing should be included in projections of the role of Arctic and Subarctic ecosystems in the global climate system,” – Dr. Kathy Kelsey. Phenological mismatch is when the timing of food and/or habitat availability for a species is altered… Read more »

Investigating Rotten Ice, with Dr. Karen Junge

Highlight: “So-called rotten 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,” – Dr. Karen Junge. Decreases in ice extent, concentration, and thickness have all been observed in the Arctic as sea ice responds… Read more »
