This scientific article, focuses on one of the largest pools of global carbon that is, the organic C stored in permafrost (perennially frozen) ground, and on the vulnerability to change under an increasingly warmer climate.
A scientific report describing the results of the CiPEHR Experiment as of 2011. This report attempts to answer these questions:
(1) Does ecosystem warming cause a net release of C from the ecosystem to the atmosphere?,
(2) Does the decomposition of old C that comprises the bulk of the soil C pool influence ecosystem C loss?, and
(3) How do
The Geophysical Institute Permafrost Laboratory (GIPL)
The Permafrost Laboratory deals with scientific questions related to the circumpolar permafrost dynamics and feedbacks between permafrost and global change. At the Permafrost Laboratory, data related to the thermal and structural state of circumpolar permafrost is collected and analyzed. The focus of our research is the development of methods to physically and mathematically model

The Kuril Biocomplexity Project is a National Science Foundation-funded research project led by the University of Washington and being conducted by a team of American, Japanese and Russian scholars and students who are examining a 5000-year history of human-environmental interactions along the Kuril Island chain in the northwest Pacific Ocean. This is the link to the project website.
Students are presented with an actual series of tundra photos, which they use to develop a hypothesis for which sort of ground cover will have the most/least permafrost depth. Then they are given a set of actual data and use this to test their hypothesis
Objective
Students will:
* understand what permafrost is and how it develops
This lesson was modeled after some of the routine activities undertaken by the geologists on the Kuril Island Expedition.
Complete the following activities:
* Day 1 To measure a simple topographic profile with a level instrument or hand level and stadium rod.
* Day 2 To use the measurements from Day 1 (and/or actual measurements from the Kuril
This activity is designed to take place near or at the end of a unit on the ocean floor. Students should be familiar with the physical features of the ocean floor including the continental shelf, abyssal plain, seamounts and guyots, seafloor ridges and trenches, and submarine canyons. The students should have also previously learned about sonar methods for mapping the
