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
This article describes PolarTREC teacher Nick LaFave's upcoming expedition to Toolik Lake, Alaska where he will be studying wolf spider populations with Duke University researcher, Amanda Koltz.
This article describes the remarkable efforts of a team of scientists to extract cores from deep under a frozen lake in Siberia, Russia. PolarTREC teacher Tim Martin joined the project which will provide an astounding record of past climates preserved in layers of lake bed sediment. The sediment, withdrawn in cores and shipped to labs in Germany, represents a continuous
PolarTREC teacher Nell Herrmann writes a compelling article for Town and Gown, the local newspaper in her home town of State College, PA. Nell reports on her adventures with a team of scientists in Antarctica and the profound way in which her journey has influenced her both personally and professionally. Note: The online article starts on p. 50 of the
ANDRILL (ANtarctic geological DRILLing) has drilled and recovered thousands of meters of rock core from beneath the McMurdo Ice Shelf in Antarctica. What secrets are hidden in this rock? Why do scientists from around the world work together to uncover these secrets that have been shrouded beneath the ice for millions of years? Join this real world geoscience adventure in
The Polar Resource Book - Polar Science and Global Climate: An International Resource for Education & Outreach - was written to ensure that the efforts catalyzed by the International Polar Year (IPY) will continue to inspire educators, students, and emerging polar researchers with a shared commitment to outreach and education.
