# 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.
