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.

本数据集收录了通过印度洋与南大洋气体观测项目（Indien Gaz Ocean, INDIGO）采集的印度洋及南大洋多站位、多深度海水样本的¹⁴C活度数据。该批数据是INDIGO 1、INDIGO 2与INDIGO 3三个航次的采集成果，三个航次依次于1985年、1986年及1987年实施。本数据集已被用于估算人为源二氧化碳在印度洋与南大洋中的渗透情况。数据记录涵盖测站编号、采集日期、海底水深、经纬度坐标、采样深度、位温、盐度、海水密度、总二氧化碳含量、¹³C活度及¹⁴C活度。
