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.

2022-02-19 Marli Miller, University of Oregon — Roadside Geology of Washington

The Lecture

On Saturday February 19, geologist and photographer Marli Miller spoke about the geology of Oregon and Washington as seen along our federal and state highways as outlined in her recent Roadside Geology books.  With its spectacular mountain ranges, lush valleys and awesome rivers, the Pacific Northwest landscape offers an incredible geologic story grounded in continental accretion and mountain-building, magmatism, and glaciation.

Beginning with the Crescent Terrane (Siletzia), the latest addition to North America, she described elements of continental accretion that form the underlying but diverse basement of the region, followed by a photographic “roadtrip” up the Columbia Gorge that illustrated younger features. Along the way, the many geologic complexities raise important questions, opportunities for new research, and fascinating stories.  The Zoom broadcast was free and open to the public, as are all our recorded events. Marli’s book on Washington Roadside Geology is available from Amazon as well as local booksellers.

The Speaker

Marli is a tenured Senior Instructor II and Researcher in the Dept. of Earth Sciences at the University of Oregon and maintains the website geologypics.com, which offers free downloads of more than 4,500 of her searchable geology photographs. This site is a godsend for instructors and authors

Ultimately, Marli thinks this whole science of geology boils down to teaching—if we can’t communicate what we’ve learned, what good is it?  Fortunately, the geology department here really values teaching, so there are plenty of people with whom she can share ideas.

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.
