The 230Th normalized opal fluxes and 231Pa/230Th ratios were measured in eleven equatorial Pacific cores to reconstruct diatom productivity over the past 30 kyr and to test the SALH. Holocene spatial patterns of opal flux are strongly correlated with 231Pa/230Th ratios and with satellite estimates of primary productivity. Down-core opal flux records do not support the SALH but show Holocene opal burial to exceed that of the late glacial period by 35%, or 2.8 Gt opal/kyr, across the equatorial Pacific. This suggests that the SALH may not account for lower atmospheric CO2 levels during the late glacial. However, the data do support results from previous studies that invoke increased El Niņoŋlike conditions during this time.
