Research Personnel

This 5-year NSERC Strategic Grant brought together researchers from Queen's University (Kingston, Ontario) and Trent University (Peterborough, Ontario) to investigate water quality issues in two of Canada's Maritime Provinces.

Graduate Students and Post-Doctoral Fellows


Brian Ginn (Post-doctoral Fellow - Queen's University)  
Brian completed his PhD in April, 2006 on using paleolimnology to track acidification in 51 NOva Scotia study lakes.  He is now shifting focus to the eutrophication side of the project and will be studying the impact of development on lakes in Cape Breton Highlands National Park, and the impact of suburban development in six Halifax lakes.

TEAM Fact: One truck backing up, one Biology building - we think the rest is self-explanatory.

Thiyake Rajaratnam (MSc Student - Queen's University)

Thiyake has a BSc (Honours) from Queen's majoring in Biology. Her project will focus on environmental change and the impact of development in 51 Halifax Region lakes.

Christina Soliman (MSc Student - Trent University)

Christina received her B.Sc. from Trent University in 2004. Prior to University, Christina worked as an environmental consultant for 1 year and completed 3 years in college studying environmental science. Christina will be using the Lakeshore Capacity Model (LCM) to evaluate the effects and interactions of stressors (i.e. elevated nutrient levels) on the studied lakes and catchments. Also, she will use the LCM to address the effects of changes in land-use as it relates to deep-water oxygen concentrations in Nova Scotia brook trout lakes.

Completed Projects



Sergi Pla (Post-Doctoral Fellow - Queen's) 

Originally from Barcelona, Spain, Sergi has a PhD  from the University of Barcelona and completed a 2 year post-doctoral fellowship at University College of London in England.  Sergi used diatoms to study trends in eutrophication in the Nova Scotia brook trout lakes.

Brian Ginn (PhD Candidate - Queen's)  
Originally from Saint John, NB, Brian recently completed his PhD studying acidification trends in 51 Nova Scotia lakes.  His study involved constructing a 494-lake diatom-environment calibration set from northeastern North America;  comparing present-day and pre-impact diatom assemblages to detail water quality changes; and an analysis to study decadal changes in 14 lakes from Kejimkujik and Cape Breton Highlands National Parks, tracking both the timing of acidification and the role of DOC.

Colin Whitfield (MSc - Trent)

Colin's research investigated lake catchment response to acidic deposition using a biogeochemical process-based model (MAGIC) to recreate past environmental conditions and simulate future conditions of 20 low-order (i.e. headwater) Nova Scotia LRTAP lakes.  The use of process-based models, in combination with critical and target sulphate load estimates will enable evaluation of current recovery from acidification (if any) and, based on current sulphate scenarios, expected future recovery (or deterioration) of lakes.  Model simulations were run under current climatic conditions, and future climate change scenarios, to compare and assess the potential impact of climatic change.

AnneAnne Harris (MSc - Queen's)

Hailing from Midland, Ontario, on the shores of scenic Georgian Bay, Anne has a BSc (Hons) from Queen's University.  Anne's research will study the effects of acid deposition on lakes in New Brunswick using diatoms as paleoecological indicators.  Using lakes from Environment Canada's and the Canadian Wildlife Service's LRTAP monitoring program, Anne will study present-day and pre-impact diatom assemblages to track acidification trends on all lakes as well as detailed analysis of selected lakes.

Michael Rate (MSc Student - Queen's) 
Mike's research will also centre on acidifcation of the Nova Scotia LRTAP lakes using scaled chrysophytes as a paleoecological indicator.  After constructing a chrysophyte-based calibration set, he will use top-bottom analyses to track environmental changes that have occurred in these lakes since pre-industrial times.

Laura Lawlor (MSc Student - Queen's)

Laura has a BSc, double-majoring in Biology and Earth Sciences, from Dalhousie University (Halifax) and spent the past few years working as an Environmental Consultant. Laura's project, in conjunction with NS Inland Fisheries, will use fossils of chironomid (non-biting midge) larvae to study the effects of changes in nutrient loading and productivity on brook trout in Nova Scotia lakes.

Calvin Chan (BSc Honours - Queen's, 2003-2004)

Calvin's honours research focused on changes in Little Wiles Lake (near Bridgewater, NS) as related to acidification and watershed disturbance.  

TEAM Fact: Calvin is the only TEAM member to have his tent repeatly attacked by a red squirrel (Tamiasciurus hudsonicus) in the Peskowesk backcountry of Kejimkujik National Park.

Laura Stewart (BSc Honours - Queen's, 2003-2004)

Laura's research addressed the question of reproducibility of sediment in a large (2640ha) lake (i.e., is one core representative of the whole lake?) and tracked the timing of changes related to acid deposition in Kejimkujik Lake, Kejimkujik National Park, N.S.

TEAM Fact: Laura has the distinction of being the only TEAM member to be chased away from a study lake by a duck (in her defense it was rather ill-mannered).
