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.
In this lesson students research scientific field expeditions and learn what it is like working in the field. Students are able to ask questions of the research team as part of their project. Students then share what they have learned with their classmates.
Objective
1. Students understand what really goes on in the field during a scientific study.
2
An important science skill that needs to be developed is asking significant questions that advance knowledge. This activity helps students to understand the difference between significant and trivial questions.
Objective
Students should be able to distinguish between significant questions that advance knowledge and trivial questions.
Procedure
1. Have the students define significant question and trivial questions in a

This video was shot by Mike Etnier at Makanrushi Island, Russia in July 2008. This is underwater footage of one of several large schools of Atka mackerel that were feeding on krill at the surface. See "Atka mackerel and krill" for surface footage of one of the schools of fish and underwater footage of the krill. For more
This video was shot by Mike Etnier at Makanrushi Island, Russia in July 2008. There are several thousand Atka mackerel feeding on krill at the surface. See "Atka mackerel school" for under-water footage of one of the schools of fish. For more details on the feeding aggregation, and its relevance to our archaeology studies, read the journal entry
