Notes: * = Data from Murphy et al., this volume. † = Mn CaCO3-free data only calculated where shipboard Mn and CaCO3 from Murphy et al. (this volume) have same depth horizons. ‡ = Average of values for the two 2-cm intervals that comprise this depth interval, calculated for CaCO3 and reactive P, to compare these values to the barite values for the combined samples. ** = Combined samples for barite separations.
