First Order Estimation of Calving Losses from Gulf of Alaska Glaciers

Despite its importance in projections of sea level rise, dynamic mass loss from tidewater glaciers remains poorly constrained and understood. Owing to this difficulty, very few long-term or estimates of dynamic losses exist, and regional estimates of dynamic loss are nonexistent. Many studies have highlighted the importance of Alaska glaciers to sea level rise (e.g., Berthier and others, 2010). In this study, we present a detailed record of length fluctuations of Gulf of Alaska (GOA) tidewater glaciers, and propose a method to estimate calving fluxes on a regional level
