    Description: High latitude ocean-atmosphere CO2 dynamics are considered important in glacial-interglacial climate, with deep-ocean carbon burial via the biological pump being highly variable through the Quaternary. During the Mid-Pleistocene Transition (MPT) shift to 100 kyr glacials, it has been suggested that elevated atmospheric-driven iron fertilisation and increased efficiency of the biological pump in the Southern Ocean was key in lowering atmospheric pCO2 and facilitating rapid land ice accumulation. Growing evidence suggests carbon cycling in the subarctic Pacific Ocean played a key role in late Quaternary glacials, although this has not yet been assessed during the MPT. Here, the silicon isotope composition of diatoms (δ30Sidiatom) from the high productivity upwelling region in the Bering Sea is used to assess the role of the subarctic Pacific biological pump in the MPT. Results show the “900 kyr event” was characterised by low silicic acid but high nitrate utilisation, coincident with the dominance of diatom resting spores. This indicates the region became nitrate- and light-limited, rather than iron-limited, due to the development of thick pack ice and expansion of glacial North Pacific Intermediate Water (GNPIW) which suppressed nutrient upwelling. We posit that iron fertilisation from sea ice expansion, coupled with the preferential preservation and higher cellular carbon content of diatom resting spores, increased regional carbon export and contributed to lower atmospheric pCO2. Remnant iron and remineralised silicic acid also likely propagated into the lower subarctic Pacific Ocean through GNPIW, aiding regionally high productivity once upwelling/vertical mixing was restored during deglaciations.

    Description: This dataset presents Uranium isotope, sediment residence, (bio-)geochemical, tephrochronologic, and chronologic data for the uppermost (〈5.52 m composite depth (mcd)) part of the ICDP (International Continental Drilling Program) core “DEEP” (5045-1) from Lake Ohrid (Macedonia, Albania). Uranium isotopes ((²³⁴U/²³⁸U) activity ratios) were analyzed at 16 cm resolution by means of multi-collector inductively coupled plasma mass spectrometry after sequential leaching to remove any non-detrital matter, sample dissolution and column exchange chromatography to isolate Uranium from the matrix. Gas sorption analyses were conducted on leached material of selected samples to identify potential controls of surface properties and surface areas (m²/g) on uranium isotope variability, and to calculate sediment residence times of detrital matter in concert with (²³⁴U/²³⁸U) activity ratios. Sediment residence times encompass the time of detrital matter storage in the weathering horizon and fluvial transport prior to final deposition in the lake basin. (Bio-)geochemical and stable isotope data increase the resolution of data published by previous studies and encompasses total organic and total inorganic carbon contents (TOC, TIC at 8 cm resolution), Potassium and Calcium intensities, Titanium-Potassium ratios (XRF core scanning at 2.5 mm resolution), and carbon isotopes of organic matter (δ¹³Corg at 16 cm resolution). We herein also present geochemical fingerprint data from individual glass shards of three cryptotephra layer, which have not been described in the sediments of the DEEP site before.
