Paleoceanography # 16(5):468-478. #------------------ # # Description & Notes: # South Atlantic Authigenic Uranium Data. # Authigenic U can be derived from total U (reported) by subtracting a detrital # component, proportional to the Thorium-232 concentration. In the original publication # we applied a 238U/232Th detrital ratio of 0.197 by weight. # # Variables: # depth Depth (cm) # Th232 Thorium-232 # U238 Uranium-238 # # CORE: RC11-83 depth Th232 Th232_err U238 U238_err 25 7.52E-06 2.15E-07 0.0000015 2.73E-08 50 6.97E-06 9.2E-07 1.36E-06 1.99E-07 75 6.33E-06 9.34E-08 1.25E-06 1.71E-08 100 5.05E-06 1.29E-07 1.19E-06 2.7E-08 125 4.69E-06 1.44E-07 1.04E-06 3.8E-08 150 4.11E-06 8.51E-08 1.31E-06 3.22E-08 541 7.47E-06 2.43E-07 1.71E-06 5.7E-08 551 7.24E-06 2.94E-07 1.75E-06 5.85E-08 559 7.08E-06 4.02E-07 1.77E-06 9.37E-08 559 6.95E-06 3.59E-07 1.77E-06 6.02E-08 567 6.74E-06 1.54E-07 2.15E-06 7.15E-08 575 6.87E-06 2.43E-07 2.11E-06 7.39E-08 583 7.32E-06 1.62E-07 2.26E-06 4.47E-08 594 7.13E-06 1.53E-07 2.04E-06 5.36E-08 599 6.64E-06 1.89E-07 1.61E-06 3.89E-08 599 0.000007 1.28E-07 1.62E-06 4.8E-08 607 7.19E-06 6.54E-07 1.89E-06 1.14E-07 615 6.79E-06 1.83E-07 1.69E-06 4.03E-08 623 6.37E-06 1.07E-07 1.52E-06 2.26E-08
