Increasing Asian dust fluxes, associated with late Cenozoic cooling and intensified
glaciations, are conventionally thought to drive iron fertilization of phytoplankton productivity …

Much of the global cooling during ice ages arose from changes in ocean carbon storage that
lowered atmospheric CO2. A slew of mechanisms, both physical and biological, have been …

Abstract The Antarctic Peninsula's Pacific margin is one of the best studied sectors of the
Antarctic continental margin. Since the 1990s, several research cruises have targeted the …

Reconstructions of ocean oxygenation are critical for understanding the role of respired
carbon storage in regulating atmospheric CO2. Independent sediment redox proxies are …

Enhanced ocean carbon storage during the Pleistocene ice ages lowered atmospheric CO2
concentrations by 80 to 100 ppm relative to interglacial levels. Leading hypotheses to …

Over the past few million years, the Earth descended from the relatively warm and stable
climate of the Pliocene into the increasingly dramatic ice age cycles of the Pleistocene. The …

Diagenetic alteration of magnetic minerals occurs in all sedimentary environments and
tends to be severe in reducing environments. Magnetic minerals provide useful information …

Marine polymetallic nodules and crusts represent an important resource for numerous
metals such as Ni, Co, Cu, Mn and thus may be subject to deep sea mining operations in the …

Antarctic ice sheet and Southern Ocean paleoceanographic configurations during the late
Oligocene are not well resolved. They are however important to understand the influence of …

Magnetotactic bacteria (MTB) require iron and organic carbon for biomineralization, which
can be supplied by dust inputs that stimulate primary productivity in iron‐limited oceans …
