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.
Researcher Elizabeth Webb discusses her experiences working in the field with a PolarTREC teacher. She worked with John Wood in 2011 and 2012, and Tom Lane in 2013, on the Carbon Balance in Warming and Drying Tundra expedition near Healy, Alaska. (She primarily discusses her time with John Wood since this interview was taken in 2013, before Tom Lane's expedition.)
Soil decomposers, such as some bacteria and fungi, obtain energy needed for life from dead and decomposing plant and animal remains, known as soil organic matter. Soil organic matter is important to local ecosystems because it affects soil structure, regulates soil moisture and temperature, and provides energy and nutrients to soil organisms. It is also important globally, because
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
This one hour event features the GLOBE Africa and Globe Seasons and Biomes expedition to Mt. Kilimanjaro, Africa. Students and teachers that are on the expedition explain the different biomes they pass through on their way up to the summit of Mt. Kilimanjaro.
This one hour event features the expedition with the GLOBE Africa and GLOBE Seasons and Biomes program to Mt. Kilimanjaro, Africa. Dr. Kenji Yoshikawa,from the University of Alaska Fairbanks, presents on the permafrost and hydrology features of Mt. Kilimanjaro while he is on the mountain.
This is a one hour webinar is part of the Polaris Project 2012, conducted by Max Holmes and John Schade. In this session Andy Bunn, professor at Western Washington University, presents a lecture on the history and science of climate change.
This is a one hour webinar specifically for the participants of the Polaris Project 2012, conducted by Max Holmes and John Schade. In this session, a variety of team members present their scientific work.
