The Terrestrial Environmental Observation Network

The Terrestrial Environmental Observation Network (TEON) is intended to meet the need for a sustainable environmental observing network for northern Alaska. TEON is organized around representative focal watersheds. TEON will collect, distribute, and synthesize long-term observational data needed to detect and forecast effects of a changing climate, hydrology, and permafrost regime on wildlife, habitat, and infrastructure in northern Alaska.

TEON uses a “nested” approach to data collection. The smallest unit within TEON is a Station. Stations include discrete sampling locations or units (e.g., plot or transect) where repeated measures of a given variable are collected to create a time-series. Data collected at a station may be relevant to local conditions (e.g., soil temperature at a given site) or applicable to a larger area (e.g., streamgage located at the lower end of a watershed). A Site is a collection of stations that are typically located within close proximity to each other. In the figure, each site is assigned a number. Sites are grouped into Watersheds. Watersheds will encompass many ecotypes and span multiple ecoregions. Watersheds in aggregate form the TEON network.
