Toolik Snowfence Experiment: 1994-2002 Active Layer Depth


This data set contains active layer data collected for the Toolik Snowfence Experiment from 1994 to 2002. The Toolik Snowfence Experiment (part of the International Tundra Experiment network) examines the short- and long-term effects of increased snow depth (shortened growing season) and increased summer temperature on arctic tundra vegetation. The goal of this project is to assess potential changes in tundra plant communities in response to global climate change.

The research project was funded by the following Arctic System Sciences (ARCSS) Program grants:
1994 - 1998: OPP-9400083 -- ITEX / Comparative Responses of Moist and Dry Arctic Tundra to Altered Snow and Temperature Regimes
1999 - 2003: OPP-9907127 -- ITEX / Collaborative Research: Species Responses to Changes in Climate Across Arctic Gradients Using the North American ITEX Network (NATEX): Influences On Community and Ecosystem Processes
1999 - 2003: OPP-9996383 -- ITEX / Comparative Responses of Moist and Dry Arctic Tundra to Altered Snow and Temperature Regimes
