BaySys Project Amundson Expedition

Centre for Earth Observation Science


CEOS research is multidisciplinary and collaborative, seeking to improve our understanding of the complex inter-relationships between Earth systems, and how they will likely respond to climate change.

The centre manages on-and-off campus research facilities with world-class research tools using the latest technology.

  • CERC Lab

    The CERC (Canada Excellence Research Chair) Lab is a biogeochemistry laboratory designed to study certain parameters on climate change in Polar Regions. CERC Lab has capacity to study several physical, chemical and biological processes in sea ice, seawater, sediment, specimens, and atmosphere.

  • PETRL Lab

    The Petroleum Environmental Research Laboratory (PETRL) is a laboratory designed for analysis of petroleum products and their chemical composition. PETRL consists of two labs; one for sample processing and one for sample analysis.

  • Cold Lab

    The cold lab, at -26°C, allows scientists to work with snow and ice samples while retaining their natural properties. Ice cores are brought in from the field and their microstructure is analyzed in this lab.

  • Calibration Lab

    In the calibration lab, scientists set up, test, and calibrate equipment such as scatterometers (which measure the amount of energy the Earth's surface reflects) and radiometers (which measure the power of infrared radiation). It is also the lab where technical troubleshooting of instrumentation takes place.

  • Wet Lab

    In the wet lab, water samples are processed and tested. Measurements include nutrient levels, turbidity, dissolved organic matter, and pH.

  • Dry Lab

    The dry lab is mainly used for gas analysis and carbon dioxide exchange studies. Scientists also build and assemble electrical circuits to be used in their projects.
