Research Scientist

Research on mixing processes and the climate of the Gulf of St Lawrence

Current research and/or projects

Peter Galbraith is a research scientist in physical oceanography with interests in the climate of the Gulf of St. Lawrence, in mixing rates and turbulence, and how these interact with and affect biology. He is interested in identifying the underlying processes that drive the mixing that can lead to enhanced productivity. His study regions include the St. Lawrence estuary (a mixing hot spot), the Saguenay Fjord and ice-covered seas such as the Gulf of St. Lawrence in winter and the waters of the Canadian Arctic.

 

Research and/or project statements

He is chair of the Atlantic Zone Monitoring Program,  is responsible for delivering its scientific program, and sits on the permanent management and coordination comittee. With the input of colleagues, he also produces the annual Research Document on the state of the ocean for the physical oceanography of the Gulf of St. Lawrence and leads the production of the zonal environmental overview published as scientific advice. He contributes to DFO's monitoring program by running a helicopter-based winter survey of the temperature and salinity conditions in the Gulf of St. Lawrence.
