Science Summary:
This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5). The goal of this project is to maintain the existing International Tundra Experiment Arctic Observing Network (ITEX AON) and increase the applicability of the data collected to the greater scientific community. The ITEX network has collected data on phenology, plant growth, community composition and ecosystem properties as part of a greater effort to study environmental arctic change. The network, started in early 1990’s, has played a key role in advancing knowledge related to the likely impacts of a warmer Arctic through the use of experimentally warmed and un-manipulated plots (i.e., the controls) across a range of sites and ecosystems that span the major vegetation types of the Arctic. While of great value, most ITEX measurements are labor intensive and time consuming, which limit the frequency and spatial extent of sampling. Recent advances in sensor technology hold the promise to allow surrogate sampling of these manual measurements rapidly and over larger areas. This work will continue the ITEX AON observations and initiate a suite of related, non-intrusive measurements using robotic sensor platforms (networked info-mechanical systems, NIMS). These new measurements will enable scaling of measurements to the regional level by linking to existing 1 km2 sample grids and satellite imagery. These data are urgently needed to improve our capacity to monitor the impacts of changing tundra vegetation on the arctic system. This work should improve our understanding of the exchange of carbon and water across the land atmosphere interface and provide information on forage quality for herbivores.

Logistics Summary:
This collaboration is a renewal of ITEX research previously funded under lead grant 0632277. The PIs - 0856710 (Oberbauer, FIU, LEAD), 0856628 (Tweedie, UTEP), 0856516 (Hollister, GVSU) and 0856728 (Welker, UAA) -will continue ITEX measurements (and introduce novel “info-mechanical” systems to the research) at ITEX plots established at Barrow, Atqasuk, Toolik, and Imnavait Creek, Alaska, and Thule Greenland, for a 4 year period - 2010 through 2013. In 2014, research will continue in Alaska only. In 2010, the PIs will field teams (of about two per PI) at all locations for site selection and installation of experimental equipment, including boardwalk/matted trail and renewable energy power/comms systems in the Toolik area, which will be installed by CPS. (The remaining power/comms systems will be installed at Barrow/Atqasuk in 2011.) Also in 2010, PolarTREC teacher, Keri Rodgers (0956825KR) will join the Hollister team in the field. Researchers will begin arriving at Toolik Field Station in late May and will maintain a presence in the area through September, with periodic personnel change-outs. They will base from the station and drive to/from Imnavait Creek daily for work there. Barrow-area work will commence in June, with research teams travelling periodically to Atqasuk throughout the season. For the work in Thule, Greenland, Dr. Welker will have a field team of three. The researchers will travel to the Thule air base via AMC flight in late May / early June, and will spend the summer in Thule. They will be housed in the TSAR, where they also will have access to laboratory space, and will travel to and from their study sites via truck. At the end of the summer, they will store their experiment equipment and depart the station, again via AMC flight. Then, during 2011-2013, teams of 3-5 for each PI will spend June through August at the field sites. The PIs will field teams at the various sites as shown below: Toolik Field Station: Oberbauer, Gould, Tweedie, Welker Imnavait Creek: Oberbauer, Gould, Tweedie Barrow: Oberbauer, Hollister, Tweedie Atqasuk: Oberbauer, Gould, Tweedie, Hollister Thule: Welker For the 2012 work in Greenland, Dr. Welker will field a team of three. The researchers will travel to Thule Air Base via AMC flight in late May and will spend the summer in Thule. They will be housed in the TSAR, and the North Star when the TSAR exceeds capacity. They will have access to laboratory space in Building 606, and will travel to and from their study sites via truck. At the end of the summer, they will store their experiment equipment and depart the station, again via AMC flight. During the 2013 Greenland field season, Dr. Welker will field a team of four at Thule AB. The researchers will travel to Thule via AMC flights in late May and will spend the summer in Thule. One team member will deploy for a shorter field season at the end of the summer. The team will be housed in the TSAR, Bldg 353. They will have access to laboratory space in Building 606, and will travel to and from their study sites via truck. In 2014, research will continue in Alaska only from late May through August. The PIs will field teams at Toolik Field Station, Imnavait Creek, Barrow, and Atqasuk.

For all years, at Toolik Field Station, IAB will provide access to infrastructure and services. CPS will pay for Toolik user days and trucks, two power/communications systems, as well as materials to protect the tundra around the experiment sites. In Barrow/Atqasuk, CPS will provide lodging, vehicle support, communications/safety gear, lab office space, Atqasuk meals, and commercial flights between Prudhoe, Barrow, and Atqasuk. At Thule, CPS will provide AMC travel and vehicles and coordinate provision of power to the experiment site. In 2014, CPS also will provide a bear guard and NSB permitting support. UNAVCO will provide high precision GPS/LiDAR equipment and technical support as needed. The PIs will arrange for all other logistics (including shuttles to Toolik and meals in Thule, for example), and pay for them through the grant.
