Employment, Volunteer and Graduate Positions
Updated August 2018
Postdoctoral Researcher – Boreal Riverine-Coastal Biogeochemistry
The Ecosystem Indicators Team of the Ocean Frontiers Institute at Memorial and Dalhousie University, in collaboration with Department of Fisheries and Oceans and the Nunatsiavut Government, is seeking a highly motivated postdoctoral researcher with a strong background in biogeochemistry to join an interdisciplinary research initiative aimed at (1) uncovering the processes and interactions supporting coastal ecosystems of Newfoundland and Labrador and (2) developing indicators for responses of these ecosystems to climate change.
Research efforts will primarily focus on understanding how climatic changes along the land-sea continuum will impact the chemistry and primary productivity within coastal ecosystems. Specifically, the candidate will design studies to investigate how changes in the chemical composition and isotopic signatures of dissolved and particulate organic matter will impact primary productivity and nutrient cycling across geographically and climatically different watersheds.
The position will be based at Memorial University, located in beautiful, historic St. John’s, Newfoundland (https://www.newfoundlandlabrador.com/top-destinations/st-johns) in eastern Canada, and has a student population of ~18,000. Field sites will encompass rivers and their downstream estuaries within southern and eastern Newfoundland and northern Labrador.
- Candidates must have a PhD or be obtaining one by March 31, 2019 from an accredited college or university in earth or environmental sciences, oceanography, or similar program.
- Ph.D. in biogeosciences or related field such aquatic biogeochemistry, aquatic microbial ecology, or chemical oceanography
- Experience performing organic matter extractions and spectrometric and biomarkers analyses.
- Experience collecting and isolating dissolved or particulate organic matter
- Experience and willingness to work in diverse and potentially remote field settings.
- Strong written and oral communication skills with significant motivation to publish in the peer reviewed literature.
- Strong interest in team-based interdisciplinary science, with the willingness and ability to work independently when required.
- Demonstrated ability to handle and analyze diverse types of datasets using contemporary scripting languages such as R, MATLAB, and/or Python.
- Willing and able to be involved in outdoor work in rugged environments.
- Project supervisors. Drs. Susan Ziegler, Canada Research Chair in Boreal Biogeochemistry and Rachel Sipler, Canada Research Chair in Marine Biogeochemistry
Application details. To apply please send CV, including contacts for at least three references and letter describing your background and suitability for this research program to Rachel Sipler (email@example.com) and Susan Ziegler (firstname.lastname@example.org). Position is fully funded for 30 months with some potential opportunity for extension and the preferred start date between November 1, 2018 to March 31, 2019.

Ph.D. Student Opportunity ($23,000 p.a. for 4 years)
I have an opening in my laboratory for a Ph.D. student to work on the interaction between sea cage aquaculture and wild fish populations. Student support and research expenses are funded through the Ocean Frontier Institute. The research builds upon earlier research by my laboratory that demonstrates that wild fish aggregate on a large scale in the vicinity of sea cage aquaculture sites. Work currently in progress is seeking to determine whether there is evidence of bottom-up and top-down mechanisms that may be responsible attracting and sustaining these aggregations of fish. The former by identifying the relative abundance of primary and secondary producers in the vicinity of sea cages, the latter by assessing relative risk of predation, and hence the relative abundance of predators associated with sea cage aquaculture sites.
The questions to be pursued for this project will be to assess whether sea cages provide critical habitat that enhances local productivity, their role in creating complexity that enhances antipredator tactics and reducing the risk of predation, and their impact on the landscape of fear within a marine ecosystem. Research methods will primarily rely upon hydroacoustic data provided by our dedicated hydroacoustic research vessel, the Gecho II, and the use of stationary Doppler sonar, and the analysis of these data using Echoview software. While prior experience would be an asset, training and support will be provided.
Interested students should contact Mark Abrahams (email@example.com) for further information.

Honours students position available in the following areas:
1. Metagenomic analysis of fish microbiota
2. Molecular genetic analysis of bacterial pathogenes of fish
Graduate student positions available for students interested in invertebrate ecophysiology, behaviour and aquaculture/fisheries.
Opportunities in the Dr. Annie Mercier Lab:
Dr. Annie Mercier (email@example.com):
1. Biology of deep-sea invertebrates. This research involves the use of microscopy and imaging analysis techniques for the study of preserved specimens (possibly new or poorly known species). It may also involve collection of specimens (ship time) and assessment of feeding and reproductive cycles in live animals.
2. Breeding strategies of echinoderms (e.g. spawning periodicity and synchrony, ecology of brooding, fecundity, etc.). This research is based on behavioural observations, experimental trials in controlled environments, histology/microscopy, image analysis, and biochemical analysis.
3. Biology and management of the sea cucumber Cucumaria frondosa. This research focuses on the study of the Newfoundland populations of sea cucumbers with respect to an emerging fishery and potential aquaculture program. It involves the study of growth patterns, tagging and aging methods, diets, prey-predator interactions and various other aspects of the biology and ecology of the species.
4. Various other projects on the general biology and ecology of marine invertebrates (e.g. symbioses, trophic ecology, competition, behaviour, morphology, etc.).
