Recent Happenings - St. Hilaire Lab

Many members of André St. Hilaire's lab participated in the 62nd National conference of the Canadian Waters Resources Association, held in Québec City last June. Valérie Ouellet and André St. Hilaire were members of the organizing committee. The conference was a huge success, with nearly 400 participants.

André St-Hilair
e and Anik Daigle are participating in a project dealing with thermal refugia in salmonid rivers, along with other CRI Fellows (R. Cunjak and A. Curry). Thermographs were deployed in three rivers (Ouellet, Ste-Marguerite and Miramichi) during summer 2009. André is still looking for a student for this project.

Dae Jeong is a post-doctoral fellow working on the development of a statistical downscaling method in order to generate multisite climate information. He has two papers accepted about work he did in South Korea and another paper has been submitted with André and other collaborators.

Anik Daigle is still collaborating with André but for the fall semester she is teaching physics at the François-Xavier Garneau College in Québec City. We hope to see her back for the next semester. She recently published a paper dealing with modelling of the onset of the water temperature annual cycle in rivers and has submitted a paper co-authored by D. Baird and D. Peters on water temperature modelling in the OKanagan Valley.

Update on current students:

• Sandra Proulx-McInnis (MSc candidate) is presently in the field, collecting her data and enjoying surprises that come with working on fen environment! Sandra has designed a lysimeter that is able to take evapotranspiration measurements peatlands.
• Hélène Higgins (MSc candidate) is measuring turbidity at two sites on the Saint John River and waiting for the fall flood. She hopes that her instruments will not travel down to the Bay of Fundy and that they will still be waiting for her when she come back to look after them. She is wrapping up her first paper dealing with the characterization of suspended sediment regime on the Kenebecasis River.
• Mohammed Aziz Es-Salhi (MSc candidate)monitored suspended sediment concentrations downstream of two harvested peat bogs in New Brunswick for two years. He is now analyzing results and will be able to verify the efficiency of settling ponds for holding peat sediments. He is finishing his master and writing his first paper for publication.
• Dan Beveridge (MSc candidate) competed his thesis dealing with the selection of hydrologic indices that best characterise the flow regime of prairie rivers. He has completed his thesis and he will be defending soon.
• Valérie Ouellet (PhD Candidate) is back in the office after a summer in the field studying a lovely fish: carps! Now that she does not smell like dead fish any more, she will begin water temperature simulations for St. Lawrence River. Her first paper, dealing with statistical analysis of extreme water temperature and water levels associated with the 2001 fish mortality has been accepted for publication.
• Simon Tardif (PhD Candidate) compared the degree of wetness of various peatlands on the La Grand River drainage basin. He is finishing his thesis. Two papers are in preparation and one has been already accepted.
