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.
As the homepage of the website describes, "The beauty of the Arctic, its precious and fragile nature, its critical role in maintaining a stable climate for the planet, and the rapid rate of change that is occurring there must all be conveyed to the general public. Here, through digital story telling, we put a human face on science, life, societies
Students will use marshmallows to simulate toxins in the environment. Concentrations of these toxins will be modeled and calculated as they bioaccumulate up the food chain. Methylmercury and POPs are substances that bioaccumulate in the Arctic food chain. OASIS scientists studied these in Barrow, Alaska. (See Ocean Atmosphere Sea Ice and Snow (OASIS) Project at www.polartrec.com)
Students will discover how a simple action such as turning on a television will lead to toxins in our food supply. Many of these toxins concentrate in the Arctic because of long-range transport of pollutants in the atmosphere. Scientists in the OASIS project (http://www.polartrec.com/ocean-atmosphere-sea-ice-and-snowpack-interact…) study these pollutants in the Arctic. Students will learn about actions that they can take to
The international multidisciplinary Ocean - Atmosphere - Sea Ice - Snowpack (OASIS) program studies chemical and physical exchange processes between the title reservoirs. It focuses on their impact on tropospheric chemistry and climate, as well as on the surface/biosphere and their feedbacks in the Arctic. OASIS was created in 2004, is currently an IPY activity, and is planned to continue
In the Polar Discoveries Section of the Online NewsHour, professional photographer, Spencer Brown, uploaded a photjournal of scientists working as part of the OASIS campaign in Barrow, Alaska in the Spring of 2009.
Almost every student at Wilson has probably heard of Mrs. Wilkening, a seventh grade teacher with a mad passion for science. She keeps her science classes alive with her eccentric and fun lessons. Mrs. Wilkening also has had two kids go through Wilson herself. Patrick, her son, was actually part of this school's first kindergarten class, and Jeannie, her
