  • Marine sediments deposited beneath the eastern Pacific upwelling margin are a substantial sink for silica. The geochemistry of these sediments suggests that periods of intense upwelling result in iron limitation, which enhances the export of silica from the surface to the deep ocean and sediments.

  • Global atmospheric CO2 varies between glacial–interglacial cycles. Here, the authors study these changes using Si records and how the Si flux and ocean circulation changes controlled the global Si distribution across the last deglaciation, based on high-resolution Si-isotope records from the Indian Sector Southern Ocean.

  • Oceanic anoxia is invoked for driving the Permo-Triassic Mass Extinction, but the timing, distribution and chemical state are poorly understood. Here, the authors show that fluctuations of anoxic, non-sulfidic (ferruginous) conditions were important for the delayed biotic recovery in the Neo-Tethys.
