Biography

Dr. Arnott’s research consists of two main parts: one experimentally oriented and the other applied. Our current applied research is studying the lithological make up and stratal geometry of deep-marine sedimentary rocks. Our principal geological laboratory is the (Neoproterozoic) Windermere Supergroup in the southern Canadian Cordillera where expansive, superbly exposed, glacially polished outcrops afford a truly unique opportunity to study deep-marine rocks at scales ranging from mm to km. Aside from academic interest, the study of these rocks has direct application to real-world questions and uncertainties related to deep-water petroleum reservoirs. Our experimental research is presently studying the effect of suspended sediment within turbidity currents. To do this we are sending live turbidity currents through a medical-quality CT scanner while concurrently measuring their 3-dimensional velocity structure. In combination these instruments are allowing us, for the first time, to accurately make the connection between flow mechanics and the various sedimentary textures and structures formed during deposition.
