2022-12-10 Marcia Bjornerud (Lecture) – Timefulness: How thinking like a geologist can help save the world

Dec. 10, 2022—Saturday 4 pm: How thinking like a geologist can help save the world

The Lecture

Developing and calibrating the geologic timescale — reconstructing Earth’s past from the raw rock record — is one of humanity’s greatest, but least appreciated, intellectual achievements.   But as a society, we are time illiterate, lacking a sense for the durations of the chapters in Earth’s history, the rates of change during previous intervals of climate instability, and the intrinsic timescales of ‘natural capital’ like groundwater systems.  This matters because environmental wrongs, social conflicts and existential malaise are all rooted in a distorted sense of humanity’s place in the history of the natural world.  Thinking like a geologist can simultaneously ground us and elevate us. Paradoxically, this Earth-bound, very physical science can yield transcendent insights.

Timefulness was longlisted for the 2019 PEN/E.O. Wilson Prize for Literary Science Writing and was a finalist for the 2018 the Phi Beta Kappa Award in Science, and the LA Times Book Prize in Science & Technology.

The Speaker
Marcia Bjornerud, Professor of Geosciences at Lawrence University in Wisconsin, is a structural geologist whose research focuses on the physics of earthquakes and mountain building. She combines field-based studies of bedrock geology with quantitative models of rock mechanics. She has done research in high arctic Norway (Svalbard) and Canada (Ellesmere Island), as well as mainland Norway, Italy, New Zealand, and the Lake Superior region.  Bjornerud is a Fellow of the Geological Society of America and has been a Fulbright Senior Scholar at the University of Oslo, Norway and University of Otago, New Zealand.   A contributing writer to The New Yorker, Wired, the Wall Street Journal and the Los Angeles Times, she is also the author of several other books for popular audiences — Reading the Rocks: The Autobiography of the Earth and Geopedia: A Brief Compendium of Geologic Curiosities.

2022-04-02 Kim Juniper, Univ. of Victoria: The Battle for the Abyss

The Battle for the Abyss:  Mining, conservation, and bioprospecting interests square off on the deep sea

The Lecture

Nearly 60% of the surface of our planet is covered by more than 2000 m of water. The deep seabed is the largest and least explored ecological region on Earth. With no light for photosynthesis, this cold high-pressure environment is a food desert, with most organisms feeding on organic debris that sinks from the surface ocean. Yet, there are an estimated 500,000 or more species in the deep sea, many of which occur nowhere else. The abyss has seen relatively little disturbance from human activities, but that situation is poised to change. Economic growth is driving increasing demand for base metals and rare-earth elements. Known mineral resources on land will soon be insufficient.  Seabed mining is now technologically feasible and regulatory agencies such as the International Seabed Authority are currently finalizing regulations for mineral extraction.  Environmental disturbance from seabed mining operations will be significant, with some mining operations at the scale of 10,000 square kms or more. My presentation will shine some light on the current debate between deep-sea mining interests and the interests of biodiversity conservation and genetic resource biodiscovery. And I will also touch on some of the technologies that are being used for deep-sea exploration.

Manganese nodules, cobalt-rich manganese crusts, and polymetallic sulphides comprise the major mineral deposits that are currently being considered for mining. The romantic view of deep-sea mining that emerged in the mid-20th century must now contend with the realization that each of these deposits host unique faunal and microbial communities that would be severely impacted by mining operations.  Together, we will explore each of these environments and their inhabitants through imagery collected by research submersibles, and learn more about their biodiversity, their contribution to ocean ecosystem function, and their potential for biotechnological and pharmaceutical applications.  We will also introduce some of the players in this “battle for the abyss,” from regulatory agencies to mining companies, deep-sea biologists and Big Pharma.

Kim Juniper is Chief Scientist with Ocean Networks Canada (ONC), a University of Victoria-basedorganization that operates cabled ocean observatories in the Pacific, Arctic and Atlantic Oceans. He is also Professor in UVic’s School of Earth and Ocean Sciences and Department of Biology, and holder of the British Columbia Leadership Chair in Ocean Ecosystems and Global Change. He has authored more than 130 peer-reviewed publications on the microbiology, biogeochemistry and ecology of deep-sea hydrothermal vents, and low oxygen and other marine habitats. He has contributed scientific leadership and advisory roles to many national and international initiatives including, most recently, the Canadian Healthy Oceans research network (CHONe), the Partnership for Observation of the Global Ocean (POGO), OceanObs’19 and OceanObs Next, the North Pacific Marine Science Organization (PICES), and the European Marine water Column and Seafloor Observatory (EMSO-ERIC). He served as an occasional advisor to the International Seabed Authority during the development of regulations for the exploration and extraction of seabed mineral resources in areas beyond national jurisdictions. His current research is focusing on bio-prospecting methods for the assessment of the microbial genetic resources associated with seafloor massive sulphide deposits.

2022-05-14 George Mustoe, WWU Bellingham:  The Chuckanut—Not just another good brewpub

Washington’s fossil footprints—Tracking birds and beasts of a bygone era

 

The Lecture

The Chuckanut Formation is one of North America’s thickest sequences of non-marine sediment.  It was deposited by a meandering river that flowed westward across Washington at a time when the Cascade Range had not yet been created. The strata accumulated to a thickness of at least 6,000 meters (20,000 ft). The oldest beds were deposited in the late Paleocene, but most deposition occurred in the early Eocene.
The warm early Cenozoic climate allowed subtropical rainforests to flourish. Abundant plant fossils in the Chuckanut include fronds from palms, tree ferns, and diverse array of other plants. Beginning in the 1990s, tracks of birds and animals were found in its outcrops in the Mount Baker foothills east of Bellingham, Washington. Twenty years of collecting has resulted in the discovery of a multitude of fossil tracks that were produced by birds, reptiles, and mammals. This presentation will describe and illustrate these discoveries.

The Speaker

George Mustoe was born and raised in Nevada, arriving in Bellingham with his family at the formative age of 15. After some years at WWU getting educated as a geochemist, he eventually made a switch to paleontology as his main research interest. George has published close to 100 peer-reviewed journal articles that span a range of geoscience topics—a publication record that he cites as evidence of wide-ranging scientific interests or maybe just a short attention span. Following his retirement in 2014, George became a Geology Research Associate at WWU where he continues his pursuit of paleontology.
