Topics course.: Coral reefs occupy a small portion of Earth’s surface, but their importance to the marine ecosystem is great. This seminar considers the geologic importance and ecological interactions of coral reefs. We focus on the status of coral reefs worldwide, considering effects of environmental and anthropogenic disturbances (e.g., major storms, eutrophication, acidification, overfishing). Methods for reef conservation are examined. Prerequisite: permission of the instructor.
