Catastrophic Ice Shelf Breakup as the Source of Heinrich Event Icebergs

Abstract: [1] Heinrich layers of the glacial North Atlantic record abrupt widespread iceberg rafting of detrital carbonate and other lithic material at the extreme-cold culminations of Bond climate cycles. Both internal (glaciologic) and external (climate) forcings have been proposed. Here we suggest an explanation for the iceberg release that encompasses external climate forcing on the basis of a new glaciological process recently witnessed along the Antarctic Peninsula: rapid disintegrations of fringing ice shelves induced by climate-controlled meltwater infilling of surface crevasses. We postulate that peripheral ice shelves, formed along the eastern Canadian seaboard during extreme cold conditions, would be vulnerable to sudden climate-driven disintegration during any climate amelioration. Ice shelf disintegration then would be the source of Heinrich event icebergs.

Management Innovation in a VUCA World: Challenges and Recommendations:

Abstract: Our Call for Papers focused on breaking established patterns and models and showcasing management innovation in a world in which Volatility, Uncertainty, Complexity, and Ambiguity (VUCA) reign. VUCA is both an outcome of disruptive innovation and a driver of it; and frequently VUCA is used as an excuse to avoid planning and action. While research has pursued the four elements independently, interaction and integration have been lacking. This article introduces three papers and offers 15 challenges as well as implicit and explicit recommendations to manage in the unpredictable and challenging VUCA world.
