Melting at Thwaites grounding zone and its control on sea level (MELT)

MELT is an ice-based project to understand how warm waters are affecting the Thwaites Glacier at the grounding line – the point where the glacier goes afloat to become ice shelf. This will allow the glacier’s potential sea-level contribution to be more accurately predicted.

MELT Team at WAIS Divide with Icefin robotic underwater vehicle

Scientists from the MELT project are in Antarctica this field season. The team aims to use autonomous sensors, vehicles (including Icefin), radar, and moorings to monitor the Thwaites ice shelf and grounding line. The team keeps a blog about the Icefin autonomous underwater vehicle: a small, long-range, deep-water, under-ice, robotic oceanographer. 

Instrument Highlight: Phase-sensitive radar (ApRES), Filchner Ice Shelf

Research teams use phase-sensitive radars for determining ice shelf basal melt rates.  Data is used to enhance climate models.

The sheer scale of the glacier captivated Ted Scambos as he looked on from his plane window, thousands of feet above the ice. The widest glacier in the world, the frozen white Antarctic landscape of Thwaites seemed to stretch on forever—an area as large as Florida, and a mile or more thick.
