What is the International Tundra Experiment (ITEX) - Arctic Observatory Network (AON)?
ITEX-AON is an NSF funded collaborative research project between GVSU, FIU, UTEP, and UAA. The goal of the project is to identify the drivers of ecosystem change across Arctic landscapes and communicate the implications of the observed changes with the public.
The field sampling occurs primarily within Arctic System Science (ARCSS) grids established in the early 90s to document ecosystem change at Utqiaġvik, Atqasuk, Imnaviat Creek, and Toolik Lake. Within each ARCSS grid there is an integrated sampling regime which includes plots, a long-term warming experiment, a mobile instrumented sensor platform (run across a 50m transect), drone sampling, fixed phenocams, and many one-time observations or experiments.
The project is also leading several syntheses of soil carbon and phenocam sampling across the ITEX network and gather information on local usage of plants in the communities of the North Slope of Alaska.
