PhD Student Opportunity: Carbon Cycling in Arctic Coastal Marine Environments
We are seeking highly motivated PhD students to study vertical CO2 exchanges within Arctic sea ice and ocean environments using field and remote sensing techniques. The goal of projects is to better define the vertical transport of carbon across atmosphere – ocean and atmosphere-ice-ocean interfaces as part of regional Arctic marine carbon budgets. Central to the research are flux measurements using eddy covariance. The positions will be housed at the Centre for Earth Observation Science (CEOS) at the University of Manitoba, and are available to start in either May or September of 2014.
Student projects will build on ongoing multidisciplinary carbon cycle work conducted within the Canadian and Greenlandic Arctic as part of NSERC, ArcticNet and Arctic Science Partnership (ASP). Fieldwork is conducted over open- and ice-covered ocean, making use of any combination of Canada’s research icebreaker CCGS Amundsen, sea ice-based experiments, and the University of Manitoba’s Sea Ice Experimental Research Facility (SERF). Details on CEOS, ASP and ArcticNet are available through links at http://umanitoba.ca/ceos/.
The ideal applicants should have strong quantitative and technical skills, and existing degree(s) in a relevant field, which may include: (micro) meteorology/climatology, oceanography, environmental science, physical geography, etc. A background in instrumentation and field research is an asset.
Please email expressions of interest or enquiries to Tim Papakyriakou at Tim.Papakyriakou@Umanitoba.ca.
MSc or PhD Student Opportunity: Heat Budgets in Arctic Coastal Marine Environments
We are seeking a highly motivated MSc or PhD student to study surface heat exchanges and microclimates of Arctic sea ice and ocean environments using field and modeling techniques. The goal of projects is to explore spatio-temporal dynamics of energy coupling between the surface and atmosphere in ocean and ice dominated environments of the Canadian Arctic. These funded positions will be housed at the Centre for Earth Observation Science (CEOS) at the University of Manitoba. The positions are available to start in May or September (2014).
The student projects will be part of multidisciplinary research conducted in the Canadian and Greenlandic Arctic as part of NSERC, ArcticNet and Arctic Science Partnership (ASP) funded projects. Fieldwork may be conducted over open- and ice-covered ocean, making use of Canada’s research icebreaker CCGS Amundsen, sea ice-based experiments, and at the University of Manitoba’s Sea Ice Experimental Research Facility (SERF). A rich multi-year data set is available to supplement field measurements in support of student projects. Details on CEOS, ASP and ArcticNet are available through links at http://umanitoba.ca/ceos/.
Ideal applicants should have strong quantitative and technical skills, background in relevant fields within any combination of micrometeorology/microclimatology, environmental science, physical geography, etc. A background in instrumentation and field research is an asset.

Student MSc Opportunity: Freshwater Sources, Distribution and Impacts on Sea Ice Formation in Southeast Hudson Bay
Hudson Bay is a shallow, seasonally ice-covered inland sea, strongly affected by river runoff. Among other factors, the river input affects the temperature, salinity, density, and rate of freeze-up of surface waters in the marine environment. Although river runoff varies naturally over time, recent decades have been characterized by more dramatic changes in the timing, volumes and location of inputs, partly driven by climate (changing precipitation patterns), and partly driven by regulation of rivers by dams, diversions, and reservoirs. Numerous large rivers (Nelson, Churchill, Moose, Eastmain, and La Grande Rivière) have been affected by regulation, causing a general shift in the seasonality of Hudson Bay discharge over time, with a decrease in spring and summer and an increase in winter. Recent reports of extremely low surface salinities in southeast Hudson Bay, associated with rapid freeze-up of large areas and wildlife entrapments in the ice, have prompted initiation of a multi-disciplinary research program to examine the wintertime marine environment in the area. CEOS will undertake research to assess the oceanography and sea ice conditions, seeking to understand the extent to which conditions reflect the cumulative effects of regulated flows resulting from hydroelectric development. The research will involve sampling and deploying oceanographic equipment from the sea ice in Hudson Bay and subsequent tracer analysis in the lab. The field work will also engage Inuit in a community-based monitoring program. We seek a student to become part of this project, ideally in January 2014 but possibly as late as April 2014.
Eutrophication is caused when freshwater lakes receive an excess of nutrients. These nutrients come from natural sources, industrial livestock operations, runoff from agricultural lands, and animal husbandry.
CEOS has started a multiyear research program on eutrophication in the Manitoba Great Lakes (Lakes Winnipeg, Manitoba, and Winnipegosis). The research seeks to understand the levels, sources, and sinks of nutrients in these three lakes using a combination of in situ sampling, time series mooring data, and satellite remote sensing. GIS analysis will be used to locate various sources of nutrients in the immediate watersheds surrounding the lakes. Historical data will be used to examine trends in nutrient inputs and how they manifest within the lakes given certain limnological processes.
We seek a student, either at the undergraduate honours or early Master's level, to assist with this work part-time. Pay will be commensurate with qualifications, and the amount of time spent on the project will account for the student's courseload and other commitments. There is also an opportunity for this project to become full time next summer and to evolve into an M.Sc. thesis.
Please send a short notice of intent and CV to Dr. David Barber.
