Notes: * = defined as three times the standard deviation of replicate measures of a low-concentration solution standard and expressed in equivalent concentration for a sediment sample. † = long-term analytical reproducibility was assessed by calculation of the mean P concentrations ±1s for two sedimentary consistency standards. ‡ = the North Atlantic consistency standard was composed of a mixture of samples from ODP Sites 1050–1052. ** = the Southern Ocean consistency standard was composed of a mixture of samples from ODP Sites 689, 690, and 738. NA = not applicable.
