Indian Ocean Radiocarbon: Data from the INDIGO 1, 2, and 3 Cruises

This data set presents 14C activities from water samples taken at various locations and depths in the Indian and Southern oceans through the Indien Gaz Ocean (INDIGO) project. These data were collected as part of the INDIGO 1, INDIGO 2, and INDIGO 3 cruises, which took place during the years 1985, 1986, and 1987, respectively. These data have been used to estimate the penetration of anthropogenic CO2 in the Indian and Southern oceans. The records include the station, date, ocean bottom depth, latitude and longitude, sampling depth, potential temperature, salinity, density, total CO2, 13C, and 14C activity.
