Eric Petersen is a PhD student working on Martian lobate debris aprons (LDAs), strange landforms interpreted as massive debris-covered glacier systems. As remnants of past obliquity-driven glacial cycles on Mars, these features are valuable indicators of Amazonian palaeoclimate. Eric's work involves using SHARAD orbital radar sounding data in conjunction with ice flow modeling and geomorphic analysis to provide constraints on LDA formation and history. He is also interested in geophysical studies of debris-covered glaciers and rock glaciers on Earth as possible analogs to Martian LDAs.
