The Arctic Ocean is a rapidly changing environment that is tightly linked to changes in the Earth’s climate. A primary focus of our group is to better understand mixing rates and mechanisms in the Arctic Ocean in the past, present and future. Read more...

Cross-shelf exchange, and especially the pathways of upwelled water across the continental shelf, the timing of its arrival at the coast, and how mixing modifies water properties, have important consequences for coastal ecosystems like those on the British Columbia coast. By working with the Canadian-Pacific Robotic Ocean Obersering Facility (C-PROOF) in close collaboration with the Hakai Institute, we are using ocean robots to monitor and better understand the processes that influence the coastal environment and their vulnerability to change.

Glaciers are melting at an alarming rate and the resulting meltwater has important impacts on the marine environment and its ecosystems via mechanisms that are poorly understood. In this project, we aim to understand how glacial meltwater impacts local marine ecosystems, including the humans they support. Read more...

Nonlinear interactions in geophysical flows are critical to their nature, transferring energy and allowing for smaller-scale circulation features to feedback on the larger-scale flow. Representing these interactions in Earth system models remains a pressing challenge. We probe a better understanding of non-linear interactions and novel ways to better represent them in climate models using theory and idealized process modelling. Read more...

Making high-density and long-term measurements of ocean turbulence from autonomous ocean observing platforms is an exciting recent technological advance that hold great promise for revolutionizing our understanding of how the oceans work. We contribute to pushing the boundaries on our capabilities to measure and understand ocean turbulence by deploying an Ocean Microstructure-equipped Glider (OMG) and working with other groups worldwide to pioneer the analysis and interpretation of microstructure data collected from the glider platform.
