| contents | The barite and CaCO3 content (in weight percent) of marine sediments can be used to determine spatial and temporal changes in export production (organic and carbonate carbon flux) and/or CaCO3 preservation (inorganic carbon burial). Here we report barite and CaCO3 content in Eocene/Oligocene (E/O) boundary sediments from locations drilled on Shatsky Rise during Ocean Drilling Program Leg 198. Records of these indexes may be used along with other data to determine how the major E/O boundary climatic transition (initiation of Antarctic glaciation and resultant ocean-climate system changes) affected marine export production/preservation at Shatsky Rise. Such data are necessary to elucidate the timing and phasing of changes in the carbon cycle relative to fluctuations in oceanographic conditions across this climatically important interval. |
