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) # corg% Organic Carbon weight percent # Th232 Thorium-232 # U238 Uranium-238 # # CORE: TN057-20 depth corg% corg%_err Th232 Th232_err U238 U238_err 1 0.1195 0.0179 4.3E-07 4.06E-09 0.0000001 1.61E-07 3 0.1599 -999 2.31E-07 4.06E-09 5.39E-08 2.15E-07 5 0.1224 0.0236 1.7E-07 4.06E-09 4.05E-08 1.65E-07 9 0.1396 -999 1.78E-07 4.06E-09 4.21E-08 1.88E-07 11 0.0912 0.0084 1.82E-07 4.06E-09 4.29E-08 1.23E-07 13 -999 -999 1.87E-07 8.11E-09 4.37E-08 1.61E-09 15 0.0755 -999 2.6E-07 4.06E-09 6.09E-08 1.02E-07 19 0.0657 -999 2.96E-07 4.06E-09 6.81E-08 8.89E-08 21 0.1656 -999 4.22E-07 1.22E-08 9.84E-08 2.24E-07 23 0.0985 0.0557 4.06E-07 8.11E-09 9.52E-08 1.34E-07 29 0.1894 -999 6.77E-07 1.62E-08 1.57E-07 2.57E-07 31 0.1334 0.0131 6.41E-07 8.11E-09 1.49E-07 1.8E-07 33 -999 -999 6.53E-07 1.22E-08 1.52E-07 2.41E-09 35 0.1833 0.018 8.6E-07 1.22E-08 1.99E-07 2.48E-07 39 -999 -999 8.76E-07 1.62E-08 2.03E-07 3.22E-09 41 0.2331 0.0089 8.27E-07 1.62E-08 1.92E-07 3.16E-07 43 -999 -999 8.39E-07 8.11E-09 1.95E-07 1.61E-09 45 0.2673 0.001 0.0000009 1.62E-08 2.09E-07 3.62E-07 49 0.2667 0.0016 8.64E-07 8.11E-09 2.01E-07 3.59E-07 51 0.2732 -999 8.31E-07 8.11E-09 1.93E-07 3.68E-07 53 0.3297 0.0711 1.33E-06 1.62E-08 3.07E-07 4.45E-07 55 -999 -999 7.5E-07 1.22E-08 1.76E-07 2.41E-09 59 0.2145 0.0534 6.61E-07 8.11E-09 1.53E-07 2.89E-07 61 0.2504 -999 5.47E-07 1.62E-08 1.3E-07 3.39E-07 63 0.2116 -999 5.39E-07 4.06E-09 1.24E-07 2.84E-07 65 -999 -999 5.68E-07 4.06E-09 1.33E-07 8.04E-10 69 0.3088 0.083 6.2E-07 4.06E-09 1.45E-07 4.15E-07
