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
The PolarTREC expedition places the teacher in the role of student. All aspects of the expedition ask the teacher to stretch her mind and reach beyond her comfort zone. This stretch presents itself to the teacher in having to learn new technology, new science, new presentation formats, and meet, live and collaborate with
Data collected from experimental manipulations of ecological processes can help us understand the natural world, and perhaps even help scientists predict how complex systems may change. At CiPEHR, (Carbon in Permafrost Heating Experimental Research) located near Denali National Park, scientists have collected and analyzed seven years of data to learn how increases in soil temperatures influence the carbon
This is an article detailing the alarming rate at which the Arctic is changing. The article goes through the specific examples of Sea ice, Greenland, Wildfires and Permafrost. This is a readable article for advanced middle school and high school students, and an excellent resource for teachers.
In this investigation, students will measure production of CO2 from surface water and consider the role of surface waters in the global carbon cycle and climate change. They will gather data on using Vernier CO2 sensors. This lesson presents a wonderful opportunity for student-designed experiments.
This is a good lesson to get students thinking about the complexity of the systems involved in providing our society with energy, the consequences of energy use and efficiency. Students are encouraged to explore the data sets on their own, ask their own questions about energy use and present their findings to each other.
Students will explore the concept of albedo and how it relates to melting ice and climate change. This is a hands-on activity where students measure the reflectivity of various surfaces as a model for how light interacts with different parts of the Earth’s surface. This is adapted from lessons created by Jamie Esler and SERC earthlabs.
Learning about feedback mechanisms is an important part of understanding how climate change will play out in the near and long term. Students are also exposed to the idea that scientists create simple models of complex climate systems and that feedback mechanisms play a crucial role in climate modeling.
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.
