Data to reconstruct biogenic sedimentary component time series from the Miocene Pacific to study the biological pump

DOI

We measured over 1,600 samples for POC and CaCO3, from 5 Sites of the Deep-Sea Drilling Project, Ocean Drilling Program, and Integrated Ocean Drilling Program (Sites 574, 884, 1208, U1337, and U1338) from the equatorial Pacific and North Pacific. Freeze-dried sediment samples were analyzed using coulometry and furnace methodologies presented in Lyle et al., (2000) which provide accurate POC values at very low levels. These data were analyzed from 2008 to 2012. We include XRF data for Sites 574, and interpreted XRF data for Sites U1337 and U1338. We have also included data reported for Sites 806 and 807 (Stax and Stein, 1993) from the western equatorial Pacific. We made a continuous sediment splice for Site 574 and created new age models for all drill sites to calculate mass accumulation rates to ~20 million years ago or to the base of the Neogene sediments at each drill site. Age models are also presented in the data sets.
