1998年的衛星照片，鈣板金藻遍及白令海 鈣板金藻（coccolithophores）又名球石藻、颗石藻，屬於金黃藻門（Prymnesiophyta）、钙板金藻科、钙板金藻属（Gephyrocapsa），是海洋中的一種單細胞植物，廣泛分布於海洋中。 鈣板金藻是真核微藻，人類肉眼無法辨識。鈣板金藻的細胞壁外會產生二甲基硫（DMS）的化學物質，最後形成鹽類逸散到空氣中，變成雲層的凝結核，使雲量增加，抗拒陽光的反射，可以減緩溫室效應，對地球有非常重要的貢獻。 化石 钙板金藻和硅鞭金藻等死亡后，會沉積在海底，有的形成化石，有的形成颗石虫软泥。是鑑定地质年代重要依据。死亡的钙板金藻外層有碳酸鈣質，看似美麗的外骸。 外部連結 Cocco Express — Coccolithophorids Expressed Sequence Tags (EST) & Microarray Database University of California, Berkeley.

Coccolithophores, or coccolithophorids, are single-celled organisms which are part of the phytoplankton, the autotrophic (self-feeding) component of the plankton community. They form a group of about 200 species, and belong either to the kingdom Protista, according to Robert Whittaker's five-kingdom system, or clade Hacrobia, according to a newer biological classification system. Within the Hacrobia, the coccolithophores are in the phylum or division Haptophyta, class Prymnesiophyceae (or Coccolithophyceae). Coccolithophores are almost exclusively marine, are photosynthetic and mixotrophic, and exist in large numbers throughout the sunlight zone of the ocean.
