Survey of CO2 in the oceans reveals clues about global carbon cycle

January 1996 marked the completion of the most ambitious and successful high‐precision inorganic carbon survey of a major ocean basin to date: a 14‐month, 92,000‐km‐long research cruise in the Indian Ocean. This survey, conducted in close collaboration with the international World Ocean Circulation Experiment‐Hydrographic Program (WOCE‐HP), is part of a project involving 10 U.S. universities and national laboratories that have been working together since 1990 to acquire a high‐quality inorganic carbon data set for all of the world's oceans.
