The latest findings suggest that ocean acidification by carbon dioxide may already be eroding reefs worldwide, and provide a crucial proof for a novel monitoring system tracking erosion on U.S. reefs.
A Web-based lesson called LearnEO! uses ocean color images to quantify phytoplankton seasonality and help us understand the functioning of coral reef ecosystems. Coral reefs are among the most biologically diverse ecosystems on Earth. They occupy less than 0.1 percent of the worldÛªs ocean surface, and yet they host 25 percent of all the marine species (1). Coral reefs deliver … Read More
