Abstract
Ice-flow directional data are identified as one type of geological constraint on numerical simulations of glacial dynamics in Atlantic Canada. The Geological Survey of Newfoundland and Labrador maintains a comprehensive striation database with over 10,000 observations that can be readily used for this purpose. Generally, the lack of chronological control on individual striations limits their value for constraining numerical ice models; however, we believe that a combination of data reduction and interpretation may generate an ice-flow directional database that has greater applicability. We have three goals in developing the Newfoundland striation database for ice sheet modelling: (i) to summarize ice flow directional trends at grid resolutions higher than the typical NTS map sheet scale (1:50,000); (ii) to identify regional trends in ice flow movement that can be assigned either absolute or relative age based on local geological knowledge; and (iii) to test our reconstructions against established ice flow histories at the local to regional scale. Our poster presentation will compare ice-flow trends interpreted using a variety of approaches.
