ECWG Dinner: Remote Sensing of the Cryosphere – Three Case Studies Presentation By Bruce F. Molnia

February 11 @ 6:00 pm - 9:30 pm

Explorers Club Members, Associates/Friends, Members’ Guests and Non-Members’ Guest List You are cordially invited to the February 2023 ECWG dinner meeting at the Cosmos Club, w/ after-dinner presentations by Bruce F. Molnia, Ph.D., Fn 80, U.S Geological Survey, Retired.

About the Presentation

Remote sensing is a ‘hands off’ technique or process used to image, detect, or monitor the physical characteristics of part of the Earth System by measuring or recording reflected and/or emitted electromagnetic radiation from a distance, be it centimeters to hundreds of kilometers. KRIOS is the Greek word for cold. The cryosphere is the part of the Earth System that includes frozen water and frozen ground, including sea ice, glaciers, snow, permafrost, and related frozen water features. Dr. Molnia will present three case studies examining aspects of the sea ice and glacier components of the cryosphere.

The first example will focus on satellite remote sensing of Arctic sea ice using National Imaging Systems to provide a decade-long data set designed to educate the public about sea ice processes, as well as to provide the science community with the highest resolution imagery of sea ice processes that is publicly available.

The second example will examine the changes that the Bering Glacier has experienced since it was at its Little Ice Age Maximum position at the start of the 20th century. Since 2014, part of the glacier has produced eleven high-volume outburst floods.

The third example will describe the results of Bruce’s 2019 (Glacier Bay), 2021 (Kenai Fjords), and 2022 (Prince William Sound) Alaskan expeditions using repeat photography to document annual, decadal, and century-scale changes in southern Alaskan glaciers and associated landscapes. Results document that nearly all lower elevation glaciers examined are rapidly thinning and retreating.

About our Speaker

Bruce F. Molnia, Ph.D., has more than five decades of exploration, research, community service, communication, public policy, and education experience. Molnia, who has led and participated in more than 40 polar and sub-polar expeditions, first conducting seismic studies in the Southern Ocean and Antarctic marginal seas in 1965. Since then, he has focused his research on Alaska and understanding the response of glaciers to changing climate and the dynamics of surging and tidewater glaciers. He has received many awards and public recognitions for his service, including the Antarctic Service Medal and the Explorers Club’s Lowell Thomas Award. He is the namesake for Molnia Bluff in Antarctica’s Dry Valleys. Molnia, a contractor, is currently the Senior Science Advisor for National Civil Applications for the U.S. Geological Survey National Civil Applications Center, located in Reston, Virginia.
