TL;DR: In this article, the authors show that opal burial rates and thus upwelling were enhanced during the termination of the last ice age in each sector of the Southern Ocean, and they directly link increased ventilation of deep water to the deglacial rise in atmospheric CO2.

TL;DR: A comprehensive hypothesis of how Earth emerged from the last global ice age is offered, whose prerequisite was the growth of very large Northern Hemisphere ice sheets, whose subsequent collapse created stadial conditions that disrupted global patterns of ocean and atmospheric circulation.

TL;DR: In this article, a review of the Si cycle in the modern ocean starts with the mechanisms that control the uptake of silicic acid (Si(OH)4) by diatoms and the subsequent silicification processes, the regulatory mechanisms of which are uncoupled.

TL;DR: The distribution of 234Th, 230Th, and 228Th between dissolved and particulate forms was determined in 17 seawater samples from the Guatemala and Panama basins as discussed by the authors, where the seawater first passed through a Nuclepore filter (1.0-μm pore size) and then through a cartridge packed with Nitex netting that was impregnated with MnO2 to scavenge the dissolved Th isotopes.

TL;DR: A range of complementary radionuclide proxies in sediments of the southernmost Atlantic Ocean over the past 140,000 years indicate that glacial periods were characterized by greatly increased fluxes of biogenic detritus out of surface waters.
