Haptophyte Significance 28 Isochrysis Pavlova lutheri 29
10 Haptophyte Significance Phaeocystis Colony 11 Phaeocystis is a Haptophyte. It forms a gelatinous colony. It is believed that their decaying remains are the cause of the foam on the sea shore.
Haptophyte Significance 27 Chrysochromulina 26 Prymnesium parvum
Haptophyte Significance Phaeocystis Colony Emiliania 22 DMS (Volatile) Production Fig. 10. 16 in Graham et al. 2008
Haptophyte Significance 7 Oceans = 2/3 of Earth’s Surface Carbonate Deposits = ½ of Ocean Floor Haptophytes Contribute ¼ of Carbonate on Ocean Floor 6
Haptophyte Significance 30 Haptophytes Contribute at least 25% of Vertical Carbon Transport to Ocean Floor (Graham et al. 2008)
