Rising atmospheric carbon dioxide (CO2), primarily from human fossil fuel combustion,
reduces ocean pH and causes wholesale shifts in seawater carbonate chemistry. The …

Emiliania huxleyi is numerically the most important coccolithophorid in the modern ocean
and has been intensely studied in the contexts of biogeochemistry (especially relating to the …

1.1 Background Carbon dioxide (CO2) is one of the most impor-tant gases in the
atmosphere, affecting the radiative heat balance of the earth as well as the calcium …

Twenty-five years ago, Mesozoic oceanic anoxic events (OAEs) were documented and
formalised as intervals of widespread to global deposition of organic matter. The Toarcian …

Coccolithophores, which are considered to be the most productive calcifying organisms on
earth, play an important role in the marine carbon cycle. The formation of calcite skeletons in …

The Cretaceous is a special episode in the history of the Earth named for a unique rock type,
chalk. Chalk is similar to modern deep-sea calcareous ooze and its deposition in …

Most of what is known about the distribution of blooms of Emiliania huxleyi comes from
satellite evidence. However, patches of bright water in satellite images are not always E …

Rising atmospheric CO 2 and deliberate CO 2 sequestration in the ocean change seawater
carbonate chemistry in a similar way, lowering seawater pH, carbonate ion concentration …

Carbonates are the largest reservoirs of carbon on Earth. From mid‐Mesozoic time, the
biologically catalyzed precipitation of calcium carbonates by pelagic phytoplankton has …

In laboratory experiments with the coccolithophore species Emiliania huxleyi and
Gephyrocapsa oceanica, the ratio of particulate inorganic carbon (PIC) to particulate organic …
