CALL is pleased to announce the relaunch of their popular Science and Environment Lecture Series, beginning in January. We will be using the Zoom Webinar format which allows for larger numbers of attendees and a more orderly presentation format. A Q&A feature in the Webinar platform allows for the audience to ask questions of the speaker at the end of the presentation. The sessions will be held at 7:30 PM on the first Tuesday of the month, as was the custom pre-Covid.


Shall We Gather At the River?

Irrigation and the Future of Southern Alberta’s Rivers


Southern Alberta’s rivers are at risk, currently, with the present levels of water diversions for irrigation agriculture. The irrigation sector has proposed a “modernization” scheme, funded by nearly a billion dollars of provincial funds, a loan from the Canada Infrastructure Bank and some of their own money. While irrigation efficiency has merits, it appears none of the saved water will remain in our rivers to improve declining aquatic health. Irrigation expansion, up to 230,000 acres is projected as one of the benefits of this modernization scheme. It is critical Albertans know what the implications and consequences are if this proceeds, especially without an environmental impact assessment with broad public participation.

Speaker: Lorne Fitch is a professional biologist, a retired provincial fish and wildlife biologist and a former adjunct professor with the University of Calgary. Lorne has been a biologist for 50 years, working on many issues related to use of land and water. Lethbridge is home, where he pens articles and essays on issues related to Alberta’s landscape and critters.

Arctic Coring Expedition (ACEX)

The presentation provides details of the Arctic Coring Expedition that led to the extraction of a core from the Lomonosov Ridge which extends from Greenland to Russia over the North Pole. Two large icebreakers (one a large Swedish ice breaker and the other a Norwegian supply boat set up as a drillship) left Tromso, Norway and were joined by a large Russian nuclear icebreaker at the ice edge, north of Svalbard. Once at the target site, the drillship carried out its drilling operations while the other two vessels broke up incoming pack ice so that it flowed around the drillship leaving it undisturbed. A drill core 432m in length was obtained for scientific study. The presentation will cover details of the ice conditions, drilling operations, life on board the ships, a picture of the North Pole, and some of the findings of the project.

Speaker: Roger Pilkington (Formerly with Canatec Associates International Ltd. (Now retired)
Roger started studying arctic sea ice in 1973. He then worked for Dome Petroleum and for Gulf Canada where he did research and developed methods for drilling with ships and structures in the ice infested waters of the Beaufort Sea. In 1988 he started his own company, Canatec, to provide arctic consulting services. Work done in the Sea of Okhotsk (Far East Russia) doing ice management for a Shell Oil offshore production operation led to an invitation to join a team of Canadians and Russians to provide ice management assistance to the ACEX project.
