One of the research projects that was being conducted by Kulp involved measuring the amount of radiocarbon in the dissolved inorganic carbon (CO2 + HCO3 + CO32−) contained in seawater. The primary objective was to determine the water renewal rate in the deep Atlantic Ocean. This was to be done by comparing the 14C to total C ratio in deep water with that in surface waters. The difference between these ratios could be converted to an isolation time. Assuming that the renewal rate had remained the same, this age could be converted to...
