A rare light microscope photograph of Emiliania huxleyi, a coc- colithophore. The tiny calcified plates (coccoliths) covering the cells are 6 micrometers (120 millionths of an inch) across.

Figure 14.11 Coccolithophores. 6 This electron micrograph of the abundant coccolithophore E. hux- leyi shows the small calcium carbonate plates (coccoliths) covering the cell's exterior. The coccoliths (not the organic cells themselves) act like mirrors suspended in the water and can reflect a significant amount of the incoming sunlight. The reflectance from the blooms can be picked up by satellites in space, allowing the extent of the blooms of this species to be distinguished in fine detail. lan Probert, Universite de Caen, France NASA Earth Obsenatory

Why are coccolithophores more easily seen from space than diatoms?
