02-28-2015 Wendy Gerstel: Bluff retreat

About the Talk

Bluff Retreat—What to do about the “Law of Averages”

Options for addressing coastal erosion and landslide hazards vary as much as do the combinations of bluff composition and the coastal processes acting on them. For this reason, owners, both private and public, of bluffs along Puget Sound need to consider site conditions and their geologic and geographic setting when deciding how or whether to take action to counter slope retreat. On Saturday, February 28th, Wendy Gerstel will offer insights into what must be considered for long-term adaptation to natural geologic processes and will provide a few site-specific examples of geotechnical investigations and how these relate to the broader context of unstable slopes around Puget Sound. She will discuss how and why to be clear on objectives and manage expectations for any actions taken. Wendy will touch on the rules, tools, and options that apply to living with geologic hazards associated with bluffs, and on gaining the necessary resilience we need to take on associated risks.

About the Speaker

Wendy (on the right in photo) is a licensed Engineering Geologist and Hydrogeologist and owner and principal scientist of Qwg Applied Geology, a small woman-owned business she established in 2005. She has over 30 years of experience working with Federal, State, and local jurisdictions, Tribes, non-profit groups, and private landowners throughout the U.S. and extensively in the Pacific Northwest.  Since 1992 Wendy has provided coastal geologic, geomorphic, and hydrogeologic input to a range of research, mapping, mitigation, and restoration projects. She obtained a B.Sc. in Geology from the University of New Hampshire in 1980 and her MSc. in Geology from Humboldt State University, California, in 1989.

10-03-2015 Paul Loubere: Rising Sea-Level

About the Talk

Paul Loubere will present a lecture titled Rising Sea-Level: Causes, Predictions, and Coastal Impact.  This topic should be of great interest to those that live at or near sea level.

The basic message is that “Sea-level is rising and will continue to do so well into the future as global warming proceeds, which leads to a series of basic science questions:

  • What exactly defines sea-level? 
  • It turns out that sea-level isn’t very level, why not?
  • How has sea-level varied in the past, and why?
  • What mechanisms control sea-level, and on what scales and time-spans? 
  • What are predictions for sea-level rise in the near future? 
  • What impacts does rising sea-level have on coastlines, such as ours?
  • How might coast-lines change as sea-levels rise? 

Paul Loubere’s talk will examine these questions in a non-technical way to provide perspective on the issues created by rising sea-level for our NW Pacific environment.

About the Speaker

 

Paul holds a Ph.D. in Ocean Sciences/Marine Geology from the College of Earth, Ocean and Atmospheric Sciences at Oregon State University.  He was a Distinguished Research Professor in the Department of Geology and Environmental Geosciences at Northern Illinois University and is a Professor Emeritus in that Department and the Department of Anthropology. He has over 30 years experience researching global ocean and climate systems.  He has participated on scientific expeditions in much of the world’s oceans from the Arctic to the tropical Pacific. Paul retired from teaching in 2009, moved to Port Townsend, and is on the Geology Group’s Board of Advisors.

05-14-2016 Keith Norlin: Geology of SW Parks

About the Talk

Armchair Geology of Zion, Bryce & Grand Canyon National Parks

During this hour-long lecture we sat back, learned some geologic history, and enjoyed a photographic field trip to some of America’s most magnificent landscapes. We took a virtual field trip to Zion, Bryce and Grand Canyon National Parks without getting our boots dirty. You can leave your rock hammer at home but bring your curiosity and questions.

About the Speaker

Keith Norlin is a geologist who recently retired (a second time) and moved to Port Townsend. His previous retirement job was as a geology instructor for Dixie State University in St. George, Utah, where he also led geology hikes for the Road Scholar program.

Keith is a graduate of the University of Wisconsin, where he obtained a BSc. in Geology. He spent his career as a geophysicist for the U.S. Naval Oceanographic Office, as an engineer for Westinghouse Ocean Research Laboratory, and as an exploration geologist in Australia.
