Facilities and labs
The Churchill Marine Observatory (CMO) is a globally unique, highly innovative and multidisciplinary research facility located in Churchill, Manitoba, adjacent to Canada’s only Arctic deep-water port. The CMO is dedicated to studies on the detection, impact and mitigation of spills of oil and related contaminants in sea ice-covered waters, as well as extreme weather, climate change, and fresh-water marine coupling studies.
The Sea-Ice Environmental Research Facility (SERF) is the first experimental sea-ice facility in Canada. Located on the campus of the University of Manitoba, the main feature of the SERF facility is an outdoor seawater pool (60 feet long, 30 feet wide and 8 feet deep). It is equipped with a movable roof to control snow cover and ice growth, and various sensors and instruments to allow real-time monitoring. Along with the main pool, the facility has two oil research tubs. The SERF facility also includes a trailer laboratory and a storage building.
The Ultra Clean Trace Elements Laboratory (UCTEL) is designed for the study of environmental chemistry and biogeochemistry of contaminants, especially in the Arctic marine environment. Research is carried out at both the molecular scale to probe the fundamental chemical mechanisms, and the regional to global scales to address the interplay between chemical contamination and climate change. Major research activities include biogeochemistry of mercury and other trace elements, Arctic marine cryospheric chemistry; and the interplay between chemical contamination and climate change.
