The silicon isotope composition of biogenic silica (δ 30 Si BSi) in the ocean is a function of
the δ 30 Si of the available dissolved Si (DSi; H 2 SiO 4), the degree of utilisation of the …

Biosilicification has driven variation in the global Si cycle over geologic time. The evolution
of different eukaryotic lineages that convert dissolved Si (DSi) into mineralized structures …

While marine phytoplankton rival plants in their contribution to global primary productivity,
our understanding of their photosynthesis remains rudimentary. In particular, the kinetic …

The climate during the Cenozoic era changed in several steps from ice‐free poles and warm
conditions to ice‐covered poles and cold conditions. Since the 1950s, a body of information …

Carbon plays a pivotal role in governing the climate and biosphere of Earth, yet
quantification of carbon's long‐term cycling from the mantle to the surface remains …

Silicon (Si) is the second most abundant element in the Earth's crust and is an important
nutrient in the ocean. The global Si cycle plays a critical role in regulating primary …

Marine planktonic diatoms export carbon to the deep ocean, playing a key role in the global
carbon cycle. Although commonly thought to have diversified over the Cenozoic as global …

Although there is some evidence for an Eocene monsoon, the most important intensification
of rainfall appears to start at c. 24 Ma in the Early Miocene. Many palaeoceanographical …

Authigenic clay minerals formed on or in the seafloor occur in every type of marine sediment.
They are recognized to be a major sink of many elements in the ocean but are difficult to …

Diatoms are a major primary producer in the modern oceans and play a critical role in the
marine silica cycle. Their rise to dominance is recognized as one of the largest shifts in …
