Current Graduate Opportunities


Developing an ion-exchange technique for the determination of metal bioavailability in fresh, brackish and marine waters

The Crémazy lab (www.cremazylab.com) in the Department of Biological Sciences at the University of New Brunswick, Saint John (UNBSJ) is looking for a strong and motivated student with interests in environmental chemistry and biogeochemistry, to carry out a research project on the characterization of metal bioavailability in natural waters of varying salinity.

Project description: Metal pollution in estuarine and coastal waters is a growing world-wide problem, one with particular relevance in Canada. Total metal concentration ([M]) offers limited insights into metal ecological risk in natural waters. Indeed, metal bioavailability to aquatic organisms is better predicted by the concentration of free metal ions ([Mz+]), which varies with local water physico-chemistry (e.g. pH, dissolved organic matter concentration, salinity). The ionexchange technique (IET) is one of the rare techniques that can selectively measure Mz+ species in natural waters. In this technique, the water is equilibrated with a cation-exchange resin and the amount of metal that binds to the resin (measured by atomic spectroscopy) is proportional to [Mz+] in solution. To date, the IET has only been tested in freshwater and its applicability in estuarine and marine waters remains to be established. The goal of the proposed project is to develop an IET for the measurement of [Mz+] in the full salinity range encountered in natural waters.

We will focus on four metals that are historically important to the Canadian and the New Brunswick mineral sector: copper (Cu), lead (Pb), nickel (Ni) and zinc (Zn). The key milestones will be: i) to build an IET system in the lab; ii) to calibrate the technique for each metal at varying salinity; iii) to test its selectivity and optimize the protocols (e.g. equilibrium time); and iv) to test the IET with natural water samples collected from the field.

Requirements: Applicants should have a BSc degree by time of appointment, be passionate about environmental research, have a good work ethic and strong communication skills. Prior experience in analytical chemistry, environmental chemistry, and/or geochemistry is an advantage.
Start date: Preferably September 2019, but starting date is flexible.
Funding: A full competitive stipend will be offered.
Application: To apply for this position, please email the following to anne.cremazy@unb.ca: i) a CV; ii) a description of your background and interests; iii) your academic transcripts; iv) the contact information for at least two references. Preference will be given to applications received by May 15, 2019, but application review will continue until the position is filled.

Graduate Opportunity:

Modifying the Community Aquatic Monitoring Program (CAMP) to support Marine Environmental Quality (MEQ) monitoring in PEI estuaries

This PhD or Masters opportunity is a collaboration with DFO-Gulf Region.  Since 2004 DFO has been working with the Southern Gulf of St. Lawrence Coalition on Sustainability and watershed environmental groups to sample the nekton (nearshore fish, shrimp and crabs) in up to 36 estuaries of the southern Gulf of St. Lawrence.  Every summer community groups collect environmental data and sample nekton by beach seine from six standard stations around their estuary. These data are available for analysis and can be used to answer a variety of research questions. Recent research has shown that the head of the estuary, where rivers meet the salt water, are critically important areas for monitoring environmental quality.  Therefore, the first goal of this project is to investigate the feasibility of monitoring nekton at the head of the estuary and to compare this nekton community to the community found at the standard CAMP stations further downstream.  But we also know that in some PEI estuaries sampling with a beach seine at the head of the estuary is very difficult because of blooms of sea lettuce (Ulva sp.).  Therefore, a second goal is to investigate the potential of environmental DNA (eDNA) as an alternate method of assessing the nekton community. This project is fully funded, includes an enormous amount of existing data and is suitable as either a PhD or Masters thesis. This position is available immediately. Please contact:

Ground truthing the use of environmental DNA (eDNA) for assessing Atlantic salmon population distribution and abundance

This is a full-time (2 year) Master project based at the Saint Andrews Biological Station in St Andrews (NB) and at the University of New Brunswick in St John (NB).

We are seeking a motivated MSc student to ground truth the use of environmental DNA (eDNA) for estimating the abundance of Atlantic salmon smolts. Current methods for assessing the abundance of Atlantic salmon juveniles in streams and river are time consuming, require considerable effort in the field, and risk inadvertent injury or mortality to salmon. Recent advances in the collection and analysis of environmental DNA (eDNA) provide a new complementary tool that can help fill gaps in regional species distribution data left by logistically difficult traditional methods. eDNA allows for the detection of traces of DNA in water from macro-organisms. Collecting water samples for eDNA surveys is a rapid, low-cost and non-destructive method. Though interpreting the eDNA signal beyond the presence/absence of difference species can be challenging. This project will attempt to go beyond the basic eDNA detection (presence/absence) and will use eDNA signals to estimate population abundance and distribution of specific life stages.

The successful candidate will be expected to conduct both laboratory and field work, as well as model the dispersal of eDNA molecules in streams and rivers. 

Minimum criteria:
• Bachelor in the life sciences or other relevant field
• Interest and skills for field and lab work
• Interest for molecular ecology and statistical analyses.

Applications and enquires:
To apply for this position, please send the following documentation to Dr. Anaïs Lacoursière-Roussel (Anais.Lacoursiere@dfo-mpo.gc.ca) and Dr. Scott Pavey (scott.pavey@unb.ca) by 01 March 2019:
•    Brief (<500 words) letter of interest outlining applicants interest and suitability for the project.
•    Curriculum Vitae
•    Names and contact details of at least two referees who can comment on the applicant’s relevant abilities.

Graduate Student Position
Sources and importance of Phosphorus in PEI aquatic systems

The Canadian Rivers Institute at the University of Prince Edward Island is seeking an energetic MSc or PhD student to study phosphorus and sediment flux in aquatic systems on PEI. A great deal of attention has been put on the study of nitrogen pollution on PEI due to the dominant role of nitrogen in estuarine and coastal zone eutrophication. Comparatively little work has been conducted on annual loadings, storm flux, and sources of phosphorus, particularly orthophosphate, on PEI. Preliminary information suggests phosphate concentrations vary by almost 20-fold in PEI streams, in a gradient from West to East, do not appear to be linked to agricultural activity, and may vary substantially during rain events. The project would initially involve measuring annual phosphorus loadings in two agricultural sub-watersheds, including determining storm loading. Sources and variability of phosphorus in groundwater would be determined within those sub-watersheds. Due to the close relationship expected between phosphorus and sediment during storm event, additional sediment monitoring would be conducted using acoustic backscatter devices. The nature of phosphorus variability on UPEI as a whole would be explored, potentially investigating the age of water in the many springs with differing phosphate levels. Initial work would occur at two established monitoring field locations operated by Agriculture and Agri-foods Canada (AAFC). If a PhD were recruited for this position, the project would be expanded in order to better understand the role of phosphorus in estuarine eutrophication. The successful candidate will work as part of a team on the AAFC Living Laboratory project and this team would include members of the agricultural community on PEI and scientists at the National Research Institute in Quebec (INRS) and the University of Waterloo. The position is contingent on the successful completion of contracting with the funding partners. Applications will be sought until a suitable candidate is found, and may be directed to Mike van den Heuvel, mheuvel@upei.ca.
