Abstract

Radiocarbon data for the Atlantic, Pacific, and Indian oceans were obtained between 1972 and 1977 as part of the Geochemical Ocean Section Study (GEOSECS) cruises during which more than 2200 water samples were collected. Some Mediterranean Sea data were also collected. Samples for ¹⁴C were collected at 124 stations, and approximately 18 samples were collected at each station from intervals throughout the water column. The data included in the data base are ship position (latitude and longitude), sample number, depth, potential temperature, salinity, and delta ¹⁴C. The GEOSECS data sets allow a better understanding of large-scale oceanic transport and mixing and the establishment of the gross rate of deep-ocean circulation. The data are in three files (radiocarbon data for the Atlantic, Pacific, and Indian Oceans) ranging in size from 39.9 to 50.4 kB.
