IN ORDER TO BE CONSIDERED, YOUR APPLICATION MUST CLEARLY EXPLAIN HOW YOU MEET THE FOLLOWING (ESSENTIAL QUALIFICATIONS)

Currently enrolled or able to enroll in a PhD program at the University of Manitoba within the Department of Earth Sciences, following the Faculty of Graduate Studies admission requirements. https://umanitoba.ca/explore/programs-of-study/earth-sciences-phd
Degree equivalency

Laboratory otolith research experience*.

• Experience can be acquired through studies, work experience or volunteer activities.

The Arctic Fisheries and Marine Mammal Science Division of Fisheries and Oceans Canada (DFO) is based at the Freshwater Institute in Winnipeg, Manitoba. The Division provides information and advice to support the management of Arctic fisheries resources, their habitat and Marine Protected Areas (MPA) in the Northwest Territories and Nunavut, and on the Yukon North Slope. Successful management and conservation of these resources depends on acquiring, interpreting and sharing biological information, the processes affecting them and the ecosystem of which they are part.

Challenges of the position:

• To provide otolith ring/annuli structure patterns to cross-validate age-estimation using a time chronology of approximately 50-years (sclerochronology) and develop Greenland Halibut growth curves for fish captured in the Cumberland Sound Turbot Management Area commercial fishery between 1987 and 2023;
• To examine environmental proxies over the life of a fish created from otolith chronologies (periods of high growth and temperature/salinity, depth conditions using isotopic analyses);
• To improve age-estimation for Greenland Halibut by using mineralogical techniques, including microanatomy and nanostructure.
