Science Summary:
This collaborative research involves four institutions. The work addresses two major questions related to climate in the eastern Alaskan Arctic: 1) How has climate, terrestrial ecology, and pollutant transport changed over the past 250 years in this region, based on ice core reconstructions from McCall Glacier?; and 2) How well can we overcome the challenges of core proxy interpretations from ice cores taken from small polythermal valley glaciers through modern-process studies? To answer these questions the investigators will conduct an inter-disciplinary analysis of ice core proxies, atmospheric dynamics, modern processes, and numerical ice flow modeling. A 152-meter long core has already been drilled through McCall Glacier and analyzed for 35 chemical proxies. This work will focus on 1) interpretation of these proxies, 2) analysis of pollen in the core, 3) process studies to identify sources of pollen to McCall Glacier, 4) tying the weather and climate record of the past 50 years to the upper section of the core, 5) continuing 3D flow modeling of the glacier and local weather observations, and 6) conducting modern process investigations of the effects of seasonal melt on the generation of the core proxy record. The project will support two graduate students.

Logistics Summary:
The field component of this collaboration between 1023509 (Nolan, UAF, LEAD), 1023318 (McConnell, DRI), 1023214 (Cassano, CU) and 1023449 (Reese USM) involves modern process studies on and around McCall Glacier, during each of four consecutive years beginning in 2011. These studies involve coring and GPS measurements, rain water and pollen sampling. For the McCall Glacier fieldwork, the general approach is similar to fieldwork supporting grant 0714045 (Nolan, PI). A field team of about four researchers will travel to the glacier twice annually via commercial air and charters, in May and August each year, spending about two weeks each trip. Researchers will annually extract about 50m of ice cores, which will be stabilized and transported from the glacier to Reno, NV, for analysis/storage. For the pollen rain study, researchers will travel via helicopter and fixed-wing plane to about 25 remote tundra sites around McCall Glacier, of which some will stretch as far away as Toolik. The team will base at Happy Valley, Ft. Yukon or Kaktovik, depending on proximity. They will install pollen traps and take samples. For the water rain study, local observers in Ft Yukon, Arctic Village, Coldfoot, Happy Valley and Deadhorse will collect rain samples and monitor equipment. At each of these places, a researcher will travel via commercial air or truck once during the project to meet with participants.

In 2011-2013, IDDO will supply all of the drilling equipment and expertise required for this work through a cooperative agreement with NSF. In 2011-2014, CPS will provide camping gear at the McCall, satellite phone communications, and medical kits and services and UNAVCO will supply the GPS receivers and other related equipment required for this work through a cooperative agreement with NSF. The PI will pay directly for all other logistics, including commercial tickets, all subsistence and travel per diem, access to the McCall Glacier for four people and gear via fixed wing flights, all helicopter shuttles, frozen core assistance, rafts and equipment.
