The Ottawa Centre is comprised of about 90 CMOS members. The Centre holds monthly meetings downtown from September through May.  Our meetings are open to members and the public.  Meetings start with lunch followed by a presentation by an invited speaker and discussion. Occasionally our meetings are joint with partner groups or societies. 

You can sign up to receive our Meeting Notices. Please click below and send the pop-up email, or manually send to jonesb@ncf.ca



About every ten years, the Ottawa Centre hosts the annual CMOS Congress.

Outreach activities aimed at high school, university and post graduate students are a priority for the Ottawa Centre. We judge and provide prizes at regional science fairs in Ottawa and Gatineau.


Upcoming Luncheon Meeting - Wednesday 31 January 2018

SPEAKER: Karen Kohfeld, Professor, School of Resource and Environmental Management (REM), Simon Fraser University, Vancouver, BC.  Karen is the CNC/SCOR Tour Speaker (going east)

: The Oceans' Role in Atmospheric Carbon Dioxide Changes During Ice Age Cycles.

ABSTRACT: Ever since scientists discovered from polar ice cores that carbon dioxide levels were about 33% lower during ice ages compared to warm climate periods, they have been proposing theories to understand why. Since the ocean holds approximately 50 times more carbon than the atmosphere, oceanic processes are thought to be responsible. A range of physical and biological oceanic processes have been put forth to explain these fluctuations, and many can explain at least part of the total glacial-interglacial signal. However, Earth system models have yet to simulate carbon dioxide changes over a full ice-age cycle.

This presentation will show how the fossil record can be used to infer long-term changes in marine productivity, ocean temperatures, ocean circulation, westerly winds, and sea-ice cover, and how these data can be pieced together to understand the sequential timing of processes affecting atmospheric CO2 concentrations during the last full glacial cycle (130,000 years).
