Dr Treverrow completed a PhD in 2009. His research interests are focused on the dynamics of the Antarctic ice sheet. This research involved a combination of laboratory and model studies to investigate factors that influence ice sheet flow rates. In particular, the role of ice microstructure in the evolution of the highly direction dependent (anisotropic) flow properties of polycrystalline ice was investigated.
Dr Treverrow maintains an interest in field glaciology and has participated in several hot water drilling campaigns as part of the Amery Ice Shelf Ocean Research (AMISOR) project, in which a network of instrument moorings in the sub-shelf ocean cavity was established. Ice core samples obtained during the hot water drilling program have provided a rare insight into the structure and dynamics of large Antarctic ice shelves.
The Antarctic Climate and Ecosystems Cooperative Research Centre has employed Dr Treverrow since 2010.
Dr Treverrow’s current research activities at the ACE CRC are focused on ice dynamic processes, the evolution of the Antarctic ice sheet and its role in future changes to global sea levels.
His primary research activities include:
– Conducting long-term ice deformation experiments to better understand the effects of i) temperature and ii) complex stress configurations on the anisotropic flow of polycrystalline ice.
– The development a realistic numerical description of ice flow properties and validating its performance in an ice sheet model.
– Contributing to the development of techniques and data products used in the evaluation of ice sheet models, in particular the use of remotely sensed data products to understand ice dynamic processes their description within ice sheet models.
