During the first decade of the new millennium, a revolutionary approach to studying life in the sea was launched—The Census of Marine Life. Assembling over 2000 ocean scientists from 82 nations, the Census set out to answer three fundamental questions:
• What once lived in the global ocean?
• What is living there now?
• What will live there in the future?
