The goal of the team's research was to develop a past climate and precipitation record of Central Alaska over the past 1000 years. In order to accomplish this task, the team extracted and analyzed a series of three ice cores from an ice divide between the North and South Peaks of Mount Hunter within Denali National Park and Preserve. They also continued ice depth and surface velocity surveying of major glaciers within Denali National Park and have plans for using this information to develop improved ice volume estimates and historical glaciological reconstructions of Central Alaska.

Research at this site is important as it completes the development of a spatial ice core array (a range of data) in the North Pacific that has been underway since the early 2000s, including climate records from the St. Elias Mountains, Coast Range, Brooks Range, and Wrangell Mountains. Mt. Hunter in central Alaska lies in a different precipitation and climate regime from these regions, and thus represents the missing piece in this array needed to evaluate spatial precipitation and atmospheric circulation changes on various timescales in this region of the Arctic. Considering the apparent teleconnections (climate phenomena related to each other and occurring large distances from one another) between the Arctic and Antarctic climate and meteorology, completing this array of ice cores may also provide information that is particularly useful for world glaciological and climate modeling purposes. More information about the project can be found at the University of Maine website.

The team conducted research in Denali National Park and Preserve, in the Central Alaska Mountain Range. The team first flew by fixed-wing aircraft equipped with snow skis from Talkeetna, Alaska to a climber's base camp 7600 feet above sea level on the Kahiltna Glacier West Buttress. Once on the Kahiltna Glacier, the team traveled by ski and foot to 11,000-14,200 feet above sea level on the West Buttress, where they performed a variety of scientific objectives while getting acclimatized to the high elevation. Travel was on fixed rope teams for safety from crevasse falls and other hazards. The team conducted research and acclimatized for approximately two weeks on the Kahiltna Glacier prior to helicopter transport to the Mount Hunter Ice Divide at 13,000 feet above sea level where they started the ice core drilling. In the field the team lived in mountaineering tents. Temperatures ranged between -20 to 30 F during early season at the study site with winds from 0 to upwards of 40 mph.

After some final finishing touches that Erich and the others made on the second MET station at base camp (we had the same MET station there from May 2008 to June, 2012), and loading the three large twin otter airplanes with the rest of the gear, the final flights made it down to Talkeetna on a TAT…
It's time to get everything down from Mount Hunter and back to Talkeetna. Wow, did it go smoothly! The plan was for the helicopter to show up around 9:30am and start taking 700-1200 pound sling loads from the Hunter plateau down to Kahiltna Base Camp. From there, Talkeetna Air Taxi was supposed…
Tim asked me today how many km of radar data I have from this site and this got me thinking this morning while waiting for Tim and Dave to get picked up. I am on call with the land/air radio, VHF radio, and satellite phone to communicate with Erich at base camp for updates on weather, helicopter…
Mount Hunter Summit is a pretty mellow 40 minute ski from the drill site. We pretty much needed to do it. Enjoy the picture. Mount Hunter summit shot: Seth, Tim, Dave, Brad & Dom. Photo by Seth Campbell

Ken Williams - Teacher
Teacher
Nobleboro Central School

Following graduate school in 1984 Ken Williams started teaching at a small public school on the Maine coast. He has been at Nobleboro Central School ever since. New England has a tradition of community schools and Nobleboro is no exception as a K-8 school with a total student population of 130. Mr. Williams is particularly thrilled to be teaming with scientist Seth Campbell as Mr. Campbell attended Nobleboro Central during his K-8 years. Mr. Williams was a teacher and Mr. Campbell was a student during Mr. Campbellʼs middle school years between 1989 and 1991 and the two have maintained a friendship over the years. Mr. Campbell has mentored the entire Williams family on various rock climbing adventures and he has returned to Nobleboro multiple times to present his research and help Mr. Williams guide 8th grade wilderness trips. Mr. Williams likes to tell whoever will listen that Mr. Campbellʼs first backpacking experience was with Nobleboroʼs Outing Club. Although mostly a science teacher, the nature of a small school with only three faculty for grades 6-8 necessitates Mr. Williams' multi-disciplinary content work and he loves teaching reading as much as science. The small school setting, with class size routinely at ten or less, proves that relationships between students and teachers matter most. This is evident as a former student is now taking his teacher on a very excellent adventure in the Arctic. Mr. Williams believes that it is only because researcher Campbell wants to give him homework.

University of Maine

Seth Campbell is working to complete his doctoral degree through the School of Earth and Climate Sciences at the University of Maine. He is also a research physical scientist at the US Army Cold Regions Research and Engineering Laboratory (CRREL) in Hanover, NH specializing in applications of geophysics to the cryosphere. Excluding dozens of CRREL related projects, Mr. Campbell has led five glaciological research expeditions to Alaska and participated in 15 research expeditions to the Arctic or Antarctica during his career. Research through his PhD and at CRREL range from glaciology, permafrost, and glacial geology, to radio wave propagation studies. Mr. Campbell brings a vast range of other technical and professional experiences as a suitable role model to participating teachers in the PolarTREC program. He is a former rock and ice climbing guide with 17 years of climbing/mountaineering experience, a past emergency medical technician-intermediate, and instructor for Stonehearth Open Learning Opportunities (SOLO), a renowned national leader in wilderness emergency medicine education. In his free time Mr. Campbell enjoys spending time outdoors with his wife Kristin, and their Coonhound, Kinley.

Overview

This lesson/project/lab has students predict via multiple drawings and time lapse photography predictive Flubber flow before the placement of barriers and other obstacles in front of the Flubber. Contour lines in two directions are drawn on both the paper prediction and the Flubber for comparison purposes.

Overview

Ground penetrating radar is an important tool for studying glacier dynamics. Glacier scientists use GPR images to analyze attributes of glaciers. The following research activity will familiarize students with the basics of the different types of glaciers and their dynamics along with ground penetrating radar and its use in glacier studies.
