Mega-scale glacial lineations
 Discovery of a new type of large-scale (10 –100 km) landform signature
(mega-scale glacial lineations) in Canada, led me to predict that these
were the specific record of high velocity ice flow (surges or ice streams).
They have since been found elsewhere, and in the last few years, remarkable
submarine finds have been made on the continental shelf surrounding
Antarctica. These are significant in that their context in relation
to fast flow features in the existing ice sheet validate my predictions.
It is thus now well established that mega-scale glacial lineations are
a reliable record of ice stream flow. Current research explores the
formation of these landforms and their wide-reaching implications on
the controls of ice stream flow.
