Coccolithophores

Seawater chemistry, coccolithophore population growth, and ...

These results support the hypothesis that both the low Mg/Caratioandthe high concentration of Cain Cretaceous seawater were responsible for the high growth rates of coccolithophores that produced massive Cretaceous chalk deposits (Stanley and Hardie, 1998,1999) at a time when the high con- ...

Biomineralization Within Vesicles: The Calcite of Coccoliths ...

coccolithophores would show simpler biomineralization mechanisms than higher organisms (Westbroek pers comm.). However, coccolith biomineralization has proven to

Coccolithophore assemblages and morphotypes of Emiliania huxleyi

coccolithophores was high, although diversity was low. The floral assemblage was dominated by E. huxleyi Type B and consistently contained Coccolithus pelagicus ssp.

That concludes that series of events, but now we need to return to the surface where we will talk about a special kind of phyotplankton known as the coccolithophores.

Climate change and the oceans

The Bering Sea experienced highly unusual marine and atmospheric conditions in 1997-1998; weak winds coupled with strong sunlight created highly stratified, low-nutrient surface waters in the summer of 1997 in the eastern Bering Sea, and a massive bloom of coccolithophores resulted.

Satellite-detected early summer coccolithophore blooms and ...

Coccolithophores constitute a key component of the ocean-atmosphere sulfur cycle through the release of dimethysulfide (DMS), known as the main natural source of atmospheric sulfur and thought one of the key regulators of present-day climate ( Charlsonand Wigley, 1994; Holligan et al., 1993 ; Simo, 2001 ...
