What's New in the Emiliania huxleyi WWW Site


03/07/09: Coccolithogenesis: Alison Taylor has produced a wonderful time-lapse video showing another coccolithophore (Coccolithus pelagicus) building its coccoliths inside the cell and then extruding them out onto the cell surface. The coccoliths are rather large relative to the cell size; if scaled up to human size it would be like a person giving birth to a car wheel or a dustbin lid.

12/03/08: Added link to an animation by Glynn Gorick showing viral infection of an Ehux cell (Windows Media Player) (Quicktime) from the BlueMicrobe DVD.

17/01/07: Added links to a web site describing mesocosm experiments to investigate ocean acidification effects on ccocolithophores, the Pelagic Ecosystem CO2 Enrichment Study (PeECE)

12/04/05: Amended the "Grim Future for Ehux?" page in light of high [Ca] and unexceptional CCD during the Cretaceous, which argue that the future will not be like the Cretaceous for coccolithophores, even though both will be/were high CO2. This is important in assessing the impacts of the future acid ocean.

11/04/05: Added a picture of the "Chalk-Ex" experiment to the optics page.

11/04/05: Added a link to Chris Brown's monitoring pages for coccolithophore blooms.
