The Dry Valleys Ecosystem project (a Long Term Ecological Research program - LTER) has been a continuous line of research since the inception of the McMurdo Dry Valley LTER since 1992. This project seeks to test hypotheses regarding the response of Antarctic biotic communities to changes in climatic conditions over time. I participated in the 30th
Teacher Bill Henske describes the science and fieldwork behind the Dry Valleys Ecosystem Study from McMurdo Field Station in Antarctica. This presentation took place on 24 January 2023.
The attached PDF contains 5 different lessons and lab activities for high school earth science, environmental science and biology classes. The focus is on permafrost and related topics including the earth’s carbon cycle, the greenhouse effect, climate change, and aqueous geochemistry. The diagrams and photographs included in this manual, along with additional visual materials, are included in the attached Thawing
This one hour PolarConnect event is Nell Kemp and Bruce Taterka at Toolik field station studying wolf spiders and tundra/microbial interactions, respectively.
How can the ocean be colder than 0 degrees C, the temperature at which water freezes? As it turns out, the concentration of the particles (in this case, the ions from the salt) in ocean water lowers the temperature at which the saltwater will freeze. Students will learn how ocean water freezes at a lower temperature than freshwater by
