Capturing Glacial Change Through 3D Time-lapse Photography on the Helheim Glacier, Greenland

At nearly 4-miles wide and flowing at speeds of up to 90-feet per day, the Helheim Glacier in southeast Greenland is one of the main tidewater glaciers draining the Greenland Ice Sheet, contributing to global sea level rise. Capturing measurements of the glaciers movement on a daily timescale, needed to understand how changing atmospheric and ocean conditions affect the glaciers speed, is extremely difficult due to its vast scale and remote location. Satellite imagery provides detailed information on these areas, but rely on long orbit times and clear skies to image the glacier. Onsite time-lapse cameras installed at glaciers around the world have visually uncovered the hourly movement of the ice, yet are not quantitative measurements. In this talk, LeWinter will discuss the Greenland Atlas Project designed to fill this gap in knowledge, from the multiple years of developing and testing a long-range laser scanner, to the engineering of the fully autonomous terrestrial laser scanner (Atlas) system to be deployed and operated year-round at Helheim Glacier to capture high-resolution 3D time-lapse imagery. The system is complex, must be completely self-powered and controlled onsite, and will be faced with some of the harshest conditions on the planet.

Adam LeWinter is an engineer and scientist at the US Army Corps of Engineers Cold Regions Research and Engineering Laboratory, where he focuses on large scale changes in glacier, alpine, and volcanic settings using state-of-the-art laser scanning. Ranging from the Greenland Ice Sheet to Kilauea Volcano, Hawaii, LeWinter specializes in collecting visually captivating data in the most extreme environs. LeWinter was the lead engineer and field manager for the Extreme Ice Survey, and is an Emmy Award winner for his work on the film Chasing Ice. His work aims to reveal processes in nature that are hidden to the naked eye.

 

Tea, donated by Two Leaves and A Bud and Paradise Bakery cookies will be offered.

Adam will also be presenting on Wednesday, January 21 at 5:30 at Carbondale's Third Street Center.

A Fire History of Hunter Creek Valley

Fire is a critical ecosystem process shaping patterns of forest characteristics from stands to landscapes in the western United States. Following a century of fire suppression practices in the region, natural patterns of wildfire have been significantly altered in many forest types, resulting in significant ecological consequences. Specifically, unnatural patterns of fire have resulted in unnatural forest conditions (species composition and tree density) and set the stage for extensive, high-severity fires and bark beetle outbreaks. Consequently, forest ecosystem management actions are focused on restoring forests to pre-fire suppression characteristics. Restoring forests to natural conditions has the added benefit of increasing forest resilience to the impacts of climate change. However, not all forests have been impacted by fire suppression, and management activities intended to restore stands in these forests could actually create unnatural forest conditions and decrease system resilience to climate change impacts. Consequently, it is essential to identify the need for restoration for individual sites and forest types before implementing restoration activities. In this talk Jason will present results from a tree-ring based reconstruct of fire history for Smuggler Mountain and the Hunter Creek drainage, and their implications for the need for forest restoration at the site.

Jason S. Sibold (PhD) is an assistant professor of geography in the Department of Anthropology at Colorado State University. Dr. Sibold’s research focuses on the role of wildfire, insect outbreaks and their interactions in shaping forests in the US RockyMountains and southern Chile. Dr. Sibold was recently called to testify before the House Committee on Natural Resources on the scientific understanding of bark beetle outbreaks and their interactions with wildfires. His research is supported by the National Park Service, US Geological Survey, Aldo Leopold Wilderness Research Institute, Fulbright Scholars Program and Joint Fire Sciences Program and has been published in journals including Ecological Applications, Journal of Biogeography, Canadian Journal of Forest Research and Landscape Ecology.

DamNation

This powerful film odyssey across America explores the sea change in our national attitude from pride in big dams as engineering wonders to the growing awareness that our own future is bound to the life and health of our rivers. DamNation's majestic cinematography and unexpected discoveries move through rivers and landscapes altered by dams, but also through a metamorphosis in values, from conquest of the natural world to knowing ourselves as part of nature. Click here to learn more about the film.

Tea, donated by Two Leaves and A Bud and Paradise Bakery cookies will be offered.

The film will also be screened on Wednesday, March 4 at 5:30 at Carbondale's Third Street Center. Please note: the film screening has been rescheduled from the originally published date of January 14 & 15.

Lessons in Protecting Wildlands from Oil and Gas Development

Over the past two decades several pristine national forest lands in Montana and Wyoming have faced threats from inappropriate oil and gas development. This includes the Rocky Mountain Front and North Fork Flathead watershed in Montana and the Wyoming Range south of Jackson Hole. But through a combination of forest service planning efforts, enacted withdrawal legislation, and lease buyouts, these areas -- which total over two million acres -- are today largely protected. This talk will present lessons learned from these high profile campaigns and include discussion on what this means for protecting Colorado’s Thompson Creek Divide.

Peter serves as the Senior Director of the Northern Rockies region for the Wilderness Society. Previously, Peter worked at the Greater Yellowstone Coalition, first as a Program Associate and later as their Mining Issues Coordinator. He has also worked in Canmore, Alberta as the Outreach and Media Coordinator for the Yellowstone to Yukon Conservation Initiative, a network of over a hundred Canadian and American conservation groups working to maintain habitat connectivity from the Greater Yellowstone ecosystem to the central Yukon Territory. Peter earned B.A. degrees in Geology and in Environmental Studies from Williams College and an M.S. in Natural Resource Policy from the University of Michigan.

 

Tea, donated by Two Leaves and A Bud and Paradise Bakery cookies will be offered.

Peter will also be presenting on Wednesday, February 25 at 5:30 at Carbondale's Third Street Center.

Ordinary Extraordinary Junco: Remarkable Biology From a Backyard Bird

Even avid birdwatchers or ornithologists who know the different juncos well may not realize that for scientists that study topics as diverse as migration, hormones, neuroscience, evolution, ecology, and disease ecology, the Junco is a rockstar study organism. For nearly 100 years, juncos have been a key research subject, in part because of their abundance and their habit of foraging and nesting on the ground, as well as the fact that they thrive in captivity. Not only are Juncos common, abundant, diverse, and found locally as well as in exotic locales–they have also played a starring role in a wide array of scientific discoveries. Click here for more information about the film.
