INTERACT is an infrastructure project under the auspices of SCANNET, a circumarctic network of currently 71 terrestrial field bases in northern Europe, Russia, US, Canada, Greenland, Iceland, the Faroe Islands and Scotland as well as stations in northern alpine areas.
The project has a main objective to build capacity for identifying, understanding, predicting and responding to diverse environmental changes throughout the wide environmental and land-use envelopes of the Arctic. You can learn more about the project in the video below:
The University of Innsbruck Station Hintereis is now part of the Alpine station network contributing to INTERACT (#21 on the map below, though these numbers change as stations are added).
If you are starting a new project, or looking for established field sites for your Arctic research then look no further than the INTERACT catalogue: http://www.eu-interact.org/station-managers-forum/publications/station-catalogue/
