Using helicopters, icebreakers, fishing vessels, and autonomous surface and underwater vehicles for over a decade, Fiammetta Straneo and her group have been probing the edge of massive calving glaciers in iceberg-choked fjords in Greenland to explore what is the Achille’s heel of glaciers – the marine edge where glaciers meet the sea.
Their goal? 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 a lack of measurements so Fiammetta and her group have probed in these polar environments to improve models of sea-level rise predictions.
