Abstract The polar oceans play a vital role in regulating atmospheric CO 2 concentrations ( p ) during the Pleistocene glacial cycles. However, despite being largest modern reservoir of respired carbon, impact subarctic Pacific remains poorly understood due to limited records. Here, we present high-resolution, 230 Th-normalized export productivity records from northwestern covering last five Our display pronounced, glacial-interglacial cyclicity superimposed with precessional-driven...
Abstract The Japan Sea was profoundly different during glacial times than today. Available δ 18 O evidence indicates that sea surface salinity lower by several per mil. This probably increased the stability of water column and caused anoxic sedimentary conditions in deep sea, as shown absence benthic microfossils presence laminated sediment. These changes are likely related to effects late Quaternary sea-level change on shallow sills (ca. 130 m) across which exchanges with open ocean. Hwang...
Abstract. We used piston cores recovered in the western Bering Sea to reconstruct millennial-scale changes marine productivity and terrigenous matter supply over past ~180 kyr. Based on a geochemical multi-proxy approach, our results indicate closely interacting processes controlling comparable situation Okhotsk Sea. Overall, inputs were high, whereas export production was low. Minor increases occurred during intervals of Marine Isotope Stage 5 interstadials, but pronounced maxima recorded...
The modern North Pacific plays a critical role in marine biogeochemical cycles, as an oceanic sink of CO2 and by bearing some the most productive least oxygenated waters World Ocean. capacity to sequester is limited efficient nutrient supply mixed layer, particularly from deeper water masses Pacific's subarctic marginal seas. region addition only weakly ventilated Intermediate Water (NPIW), which receives its characteristics Okhotsk Sea (OSIW). Here, we present reconstructions intermediate...
