Global Change

Global change, including climate warming due to the greenhouse effect, is expected to occur in the Arctic region. Variation of the Earth's surface temperature in degree Celsius. image From IPCC


Sea Ice and Marine Environment

The coverage and thickness of sea ice is decreasing in the Arctic region. The effects of meltwater on the marine environment are of concern. Sea ice concentration (%) in July 1987 and July 2006.

Marine Ecosystem

Little is known regarding the responses of marine ecosystems to global change, especially changes in fish distribution and diversity.

Distribution of Arctic cod in the Bering and Chukchi seas in 1991 and 1992.



Questions

1. What are the relationships among productivity, the diversity of marine organisms, ocean environmental conditions, and sea ice conditions under global change?

2. Has the distribution of fish species changed in relation to data collected in 1991 and 1992?

3. How do marine ecosystems respond to global change?
