PolarTREC teacher Andrea Skloss’ lesson was inspired by her Chukchi Sea Ecosystem Study aboard the USCGC Healy. In order to understand why this area is a biological hot spot of productivity, scientists must study components such as the trophic levels and more.
Objectives
In organisms and environments, the student knows that interdependence occurs among living systems and the environment
The following presentation was given by Dr. Patricia Yager at the 2012 Arctic Ocean Ecosystem Workshop in Barrow, Alaska. The presentation outlines Dr. Yager's work in biological and chemical oceanography, and focuses on the feedbacks between climate change and marine ecosystems at different locations around the world.
Excerpt from Katey Shirey's PolarTREC journal about Julie Katch, a draftsman working in Antarctica:
I returned to McMurdo Station from the South Pole and got my new room assignment, a shared 5 bed berth in the main station building. I arranged to meet up with my new friend Julie Katch whom I'd met on the way through the first time
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.
View sequential still images of thermokarst (thawed permafrost) at Horn Lake in northern Alaska during the summer of 2010. The video was made by researchers studying the responses of Arctic landscapes to permafrost degradation.
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 The sediment, withdrawn in cores and shipped to labs in Germany, represents a continuous
