PolarTREC expeditions to the Arctic and Antarctica can be found here starting in 2007 to present. You can also access archived expeditions to the Arctic that took place through TREC in 2004-2006. Journals, photos, ask the team forums, and information about each expedition can be found by following the links to all the expeditions. Use the Expedition Search feature to narrow your choices or find a particular expedition or region. Use the Members feature to find teachers and researchers involved with PolarTREC expeditions.
Another interesting perspective for viewing expeditions are Projects. Projects are expeditions that had teachers for more than one year. You can learn more about the science and see all the teachers and researchers involved in the research project over two or more years. You can also access all the related project resources (presentations, lessons, PolarConnect events, etc.) related to the projects.
Investigating Ecosystem Carbon Response in Boreal Forests
5 July 2022 - 31 July 2022
Caribou-Poker Creek, Alaska
What Are They Doing?
This study focuses on a leaf-to-watershed analysis at the Caribou-Poker Creek (BONA) Watershed in Alaska. The team will work closely with NEON (National Ecological Observatory Network). Specifically, they are looking to answer “What are the environmental and biological controls of photosynthetic phenology in permafrost-affected boreal forests?”. They will use an approach that incorporates high-frequency observations of solar-induced chlorophyll fluorescence (SIF) as an indicator of vegetation gross primary productivity (GPP), and L-band microwave backscattering intensity as an indicator of canopy water content. These measurements will be complemented by a suite of observations including leaf and ecosystem gas exchange, and environmental measurements (e.g., soil temperature, soil moisture, water flow velocity) along a soil-to-vegetation continuum.
