Measuring the ice shelf melt-rate
Ice shelves are the floating extension of an ice sheet. They fringe Antarctica, helping to restrain the flow of ice from the grounded ice sheet, thereby acting to moderate the impact of the ice sheet on sea level rise and they strongly cool continental shelf waters that flow beneath them, contributing directly to the production of Antarctic Bottom Water (AABW). The affect on sea level of thinning and loss of ice shelves from the West Antarctic Ice Sheet has been identified by the IPCC Fourth Assessment Report as a topic of concern, and, as a key element in the global ocean's overturning circulation, changes in the rate and nature of AABW production have far-reaching consequences .
This project, funded by the Natural Environment Research Council in collaboration with the British Antarctic Survey, will develop and prove the practicality of the concept of a phase-sensitive radio-echo sounder which can be left in a stand-alone mode to make a series of measurements over the period of a year or beyond.
A Research Associate vacancy is also available for this project, for a duration of 12 months
