ODP Site 882 lithic count data: Coarse lithic (>150um) abundance and flux estimates. Data reported as lithics and lithics plus fresh volcanic glass. Coarse lithic fluxes were calculated following Peck et al. (2007). Sedimentation rates were estimated from the Site 882 astronomical age model (Tiedemann and Haug, 1995) and shipboard derived dry-bulk density and GRAPE data. ODP Site 882 diatom isotopes: d30Si diatom measurements (n=30) for the interval ~2.85-2.55 Ma at ODP Site 882. Diatoms were extracted using existing techniques with analysed (75-150um) fractions dominated by two taxa; Coscinodiscus marginatus (Ehrenb.) and C. radiatus (Ehrenb.) (Swann, 2010). d30Sidiatom was analysed using step-wise fluorination at the NERC Isotope Geosciences Laboratory, U.K., with silicon collected as SiF4. Measurements were made on a Finnigan MAT 253 stable isotope ratio mass spectrometre with values corrected using NIGL within-run laboratory diatom standard BFCmod against NBS28 (Leng and Sloane, 2008). ABSTRACT SUPPLIED BY ORIGINATOR: Increases in the low-field mass-specific magnetic susceptibility (X), dropstones and the terrigenous sediment component from Ocean Drilling Program (ODP) Site 882 (~45°N) have been interpreted to indicate a major onset of ice-rafting to the sub-Arctic northwest Pacific Ocean during marine isotope stage (MIS) G6 (from ~2.75 Ma). In contrast, studies of the terrigenous content of sediments cored downwind of ODP Site 882 indicate that dust and disseminated volcanic ash deposition in the sub-Arctic Pacific increased markedly during MIS G6. To investigate the relative contribution of dust, volcanic ash and ice rafting to the Pliocene X increase, we present new high-resolution environmental magnetic and ice-rafted debris records from ODP Sites 882 and 885. Our results demonstrate that the X increase at both sites across MIS G6 is predominantly controlled by a previously overlooked mixture of aeolian dust and volcanic ash. Our findings call into question the reliability of X as a proxy for ice-rafting to the North Pacific. They also highlight a previously undocumented link between iron fertilisation and biogeochemical cycling in the North Pacific at a key stage during intensification of late Pliocene northern hemisphere glaciation.
