Student Projects

  •  MSc1 - Biogeochemistry of Canadian Arctic brachiopods – impacts of climate change; involves the geochemical (trace and REE chemistry and stable isotopes) investigation of brachiopods from the Canadian Arctic and Hudson Bay

    MSc2 - Biogeochemistry of Russian Arctic brachiopods – impacts of climate change; involves the geochemical (trace and REE chemistry and stable isotopes) investigation of brachiopods from the Russian Arctic (White Sea)

    PhD – culturing of modern brachiopods in the lab at OSC (Ocean Science Centre, Memorial University) as well as at Little Cayman Island Research Station LCIRS), using the latest flow-through aquatic systems – co-supervision with A. Mercier (OSC). Study involves culturing of cold (OSC) and warm LCIRS) water brachiopods under different temperature, pH, nutrient and oxygen regimes.

International activities & collaborations

Voting Member, Bashkirian–Moscovian Boundary Working Group (ICS Subcommission on Carboniferous Stratigraphy) with international scientists: Alekseev, Altiner, Dzhenchuarva, Fissuenko, Fohrer, Groves (chair), Kulagina, Lambert, Nemyrovskaya, Nikolaeva, Pazuhkin, Poletaev, Samankassou, Turner, Ueno, Villa & Wang.

Work progresses with J.M. Dickins ( Canberra, formerly Australian Geological Survey; dec.) and C. Korte (Ruhr University–Bochum) and others on the chemostratigraphy project of the Australian Permian sequences from the Tasman, Bowen, Sidney, Carnarvon and Canning Basins.

E. Griesshaber, Schmahl, W., Neuser, R., Job, R., Pettke, T., van den Kerkhof, Veizer, J. (Ruhr Univ – Bochum; ETH Zürich, Göttingen Univ., Fern Univ.) are collaborators on a number of projects involving the chemistry, microstructures, fluid inclusions of modern and fossil brachiopods.

Project 1: deals with an investigation into the chemical homogeneity and composition of fluid inclusions in brachiopods (modern and fossil). The investigation uses high-resolution micro-Raman spectroscopic, microthermometric and laser inductively-coupled-plasma mass-spectrometric analyses.

Project 2: Brachiopod shell calcite is being studied in detail to discern the microstructural configuration by EBSD (electron backscattering diffraction) and PIXE (proton induced x-ray emission). The architecture of inorganic biomaterials is of interest in prototype design of optimized materials, and may lead to new fabrication techniques.

Work continues with Y. Gao ( Washington State) studying the trace element and stable isotope chemistry of several Pacific fish stocks to determine ecologic health and migration patterns.
