Navigating the Perilous Waters at the Edge of Glaciers to Understand Sea Level Rise

(Visit: http://www.uctv.tv/) 0:13 - Introduction 4:44 - Navigating the Perilous Waters at the Edge of Glaciers to Understand Sea Level Rise 49:21 - Audience Questions Collapsing ice shelves and calving of large icebergs in Greenland and Antarctica have recently become major drivers of sea level rise. The rapidity of these changes has come as a surprise, revealing major gaps in our understanding of how ice sheets respond to a changing climate. To a large extent, these gaps are due to the lack of measurements from the marine edge of glaciers - the Achilles' heel of glaciers. For over a decade, since the glaciers in Greenland began their retreat, Fiammetta Straneo and her group at Scripps Institution of Oceanography have been probing the edge of massive calving glaciers in iceberg-choked fjords in Greenland using helicopters, icebreakers, fishing vessels, and autonomous vehicles. The understanding gained through these measurements is being used in models aimed at improving sea-level rise predictions. Recorded on 05/13/2019. Series: "Jeffrey B.
