Water flow beneath past ice sheets

基础水文学是控制冰盖动态及其对海平面变化影响的关键因素。来自以前冰川大陆架的地球物理数据揭示了海底通道，表明过去的冰下水流。该学生将研究过去南极洲西部冰下水流的地貌、地球物理和地质证据，包括多波束条带测深、海底剖面、地震数据和过去二十年收集的沉积物岩心分析结果。

Basal hydrology is a critical factor controlling the dynamic behaviour of ice sheets and their contribution to sea level change. Geophysical data from formerly glaciated continental shelves reveal seabed channels that indicate past subglacial water flow. The student will examine geomorphological, geophysical and geological evidence of past subglacial water flow around West Antarctica, including multibeam swath bathymetry, sub bottom profiles, seismic data and results from analyses of sediment cores collected over the past two decades.
