Martin Siegert

Martin J. Siegert FRSE is a British glaciologist, a professor at Imperial College London, and co-director of the Grantham Institute - Climate Change and Environment.[1]

Siegert earned a bachelor's degree in Geological Geophysics in 1989 from Reading University, and a PhD in the numerical modelling of large ice sheets from Cambridge University[2] in 1994.

Siegert's work involves the study of large ice sheets in the past, at present and in future, using combinations of numerical modelling, satellite observations and glacier geophysical measurements.

In 1996, he was part of the Russian-UK team that published an article in Nature revealing subglacial Lake Vostok in East Antarctica to be over 500 m deep. In the same year he published an inventory of Antarctic subglacial lakes that included Lake Ellsworth.

He is the UK PI of the US-UK-China-Australia ICECAP programme, that uses long-range airborne geophysics to measure and characterise the ice sheet and lithosphere in previously unexplored regions of Antarctica, including Totten Glacier and the Aurora Subglacial Basin, Byrd Glacier and the Wilkes Subglacial Basin, and Princess Elizabeth Land.

He was the PI of a NERC-funded airborne geophysics campaign to the Weddell Sea sector of West Antarctica (2009-2013), which showed the grounding line of Institute Ice Stream to be perched on a steep reverse sloping bed.

In December 2012 he led a NERC-funded attempt to sample Lake Ellsworth using a purpose built clean hot-water drill and water-sampling/measuring probe. The expedition was halted when the drill experienced technical problems preventing drilling to the lake surface.

In 2002, Siegert was awarded a Philip Leverhulme Prize by the Leverhulme Trust.

In 2007, Siegert was elected as a Fellow of the Royal Society of Edinburgh.[1]

In 2013, Siegert was awarded the Martha T. Muse Prize for excellence in Antarctic science and policy.[1]
