Title:  Some puzzling patterns of glacial landforms and the last Irish
ice sheet

Abstract:  Beneath any large ice sheet, rock is eroded and moved around
as a consequence of the ice flowing across the substrate. This generates
a whole range of subglacially-produced landforms, a well known Irish
example being the drumlin. Working out how such landforms are created
has understandably been a long quest given that we cannot easily observe
them forming. In this talk I will illustrate, using satellite images and
digital elevation models, what the bed of the formerly existing Irish
Ice Sheet looks like and discuss a promising theory for subglacial
landform production. I will also use their pattern, along with other
information to reconstruct the changing dimensions of the ice sheet. 

We have published the map below, which can be downloaded (at no cost)
from the Journal of Maps. Greenwood, S.L and Clark, C.D (2008).
