FACILITIES AND EQUIPMENT

PEARL is fully equipped to conduct most types of paleolimnological (as well as limnological) studies. We also apply similar techniques to general paleoecological questions involving bird and bat guano. The facilities include over 20 different sediment corers and samplers (many of which have been developed and built by John Glew), 20 high resolution microscopes, 4 ORTEC Gamma Counting Systems for sediment dating, a biogenic silica laboratory, a carbon nitrogen sulfur analyzer, a NIR spectrophotometer, three core storage cold rooms, and other facilities. In addition, PEARL shares a transmission electron microscope (TEM), and an environmental magnetism facility. Many potential collaborations are possible externally, as well as within Queen's University (e.g., with researchers at Prof. Scott Lamoureux's Environmental Variability and Extremes Laboratory (EVEX) in Geography and Prof. K. Kyser's isotope facilities in Geological Sciences, as well as present day limnological projects with Prof. Shelley Arnott). Many external collaborations are ongoing with researchers such as J. Blais, H.J.B. Birks, M.S.V. Douglas, R. Pienitz, P. Leavitt, and with many government agencies, etc.
