Robotic Network for Exploration Under Ice Shelf

Lead PI: Pierre Dutrieux

Unit Affiliation: Ocean & Climate Physics, Lamont-Doherty Earth Observatory (LDEO)

December 2016 - December 2018
Inactive
Antarctica ; Dotson ice shelf, West Antarctica
Project Type: Research

DESCRIPTION: This autonomous network of long-endurance, underwater gliders and floats collected 14 months of oceanic observations, covering a full annual cycle in Antarctica, under sea-ice and the Doston ice shelf. It demonstrated two new technologies for under ice explorations, enabling observations of water properties, currents and mixing in ice-shelf cavities. In Jan. 2018, the University of Washington and Lamont, supported by the Paul G. Allen Family Foundation and the Korean Polar Research Institute, launched 3 Seagliders and 4 EM-APEX floats to study ocean conditions underneath the Dotson ice shelf. Lack of such observations precludes accurate modeling of the ongoing rapid change of polar climate and ice sheets.
