David J. Lieske is an Associate Professor in the Department of Geography
and Environment, and is the Director of the Mount Allison University
Geospatial Modelling Lab (GML).
His research expertise encompasses spatial
statistical modelling, geographic information systems (GIS), and geovisualization.
David is particularly interested in the application of these methods to assist
environmental monitoring, mapping and conservation planning.
David is also the author of the Tantramar Community
Adaptation Viewer (TCAV), a web-based decision support toolkit for viewing
community flood risk vulnerability.

Birds are important indicators of environmental health. In the case of the marine
environment, seabirds are a key indicator of the state of the world's oceans.
Seabirds are threatened by a variety of human-driven factors:
- Oil pollution from ship traffic and terrestrial run off;
- By-catch associated with fishing activity;
- Interactions with industrial activity, such as offshore wind farms or mobile offshore
- Marine garbage;
- Climate change.
In the marine environment of the Atlantic provinces,
heavy sea traffic is thought to be a chronic source of oil discharge, of which even a
tiny amount is capable of killing seabirds. The following paper summarizes the spatial pattern
of small-scale oil pollution in Canadian maritime waters, based on aerial and satellite surveillance:
Recent GML work used state-of-the-art ensemble modelling to map the collective distribution of a
number of common and widespread seabirds in offshore Nova Scotia (Black-legged Kittiwake, Dovekie,
Much work remains to be done to better measure anthropogenic marine threats, and recent advances in
ensemble-based modelling offer new tools for measuring changes in seabird distribution
