Mass extinctions in geologic time: Implications for the past, present and future During the past 400 million years of life, evidence of five mass extinction events have been detected in the fossil record. These events caused world-wide destruction and led to collapse of whole ecosystems, producing profound changes in Earth’s history and forever altered the evolution of life. Mass extinctions constitute one of the grand “unifying themes” of our planet. Study of the strata, rocks and ancient fossils related to these episodes of massive dying are revealing much insight into not only the history of our planet, but also evolution… Read more2021-10-09 George Stanley, Univ. Montana (Emeritus)—Mass Extinctions: Five and counting
Doug Clark, professor of Geology at WWU—Bellingham will review evidence for the timing and extent of alpine (valley) glaciers in the Pacific Northwest. Abstract and bio details to follow. This will be a Zoom broadcast—Stay tuned.
Carolyn will speak about the geology/history/hazards/impact of the exchanges at the Nevado del Ruiz and Mount Rainier volcanoes, which have twin catastrophic lahar histories and hazards. In Colombia, we have had many conversations with first responders and survivors of the 1985 lahar disaster, and they have motivated US officials to double down on local efforts. Our emergency management technologies and coordination inspire the Colombians. The experiences have transformed me, as well as the official preparedness efforts in both nations. More complete abstract and bio details to follow. This will be a Zoom broadcast—Stay tuned.
Marli is a co-author of the recently updated Roadside Geology of Washington. She will feature several interesting geology sites mentioned along road routes in Washington. This is a perfect book to keep in your car for trips across or through Washington. More details to come.
Dr. Kim Juniper of Ocean Networks Canada at the University of Victoria, Victoria, B.C. will lecture on a forthcoming international mining issue, that is the underwater mining of the sea bed. Here in the northwest we are fortunate to have a plethora of marine science research and infrastructure. The University of Victoria’s Ocean Networks Canada has been monitoring the oceans since 2006 using cabled observatories, remote control systems and interactive sensors. Their goal is to support evidence-based decision-making on ocean management, disaster mitigation (re: earthquake alerts!), and environmental protection. Here is a clip from a recent article on sea-bed mining…. Read more2022-04-02 Kim Juniper, Univ. Victoria—Sea Bed Mining
The Chuckanut, not just a good brewpub Dr. George Mustoe will lecture on one of his favorite rocks, the Chuckanut Sandstone. In the late 1900s, it was a major building stone in the area, but its much more than that. Details to follow in 2022.
