Coccolithophores (also called coccolithophorids) are single-celled algae, protists and phytoplankton belonging to the division haptophytes. They are distinguished by special calcium carbonate plates (or scales) of unknown purpose called coccoliths (calcareous nannoplankton), which are important microfossils. Coccolithophores are exclusively marine and are found in large numbers throughout the surface euphotic zone of the ocean. An example of a globally-significant coccolithophore is Emiliania huxleyi.

Due to their microscopic size and the broad distribution of many of their taxa, coccoliths have become very popular as index fossils for solving various stratigraphic problems. Microfossils are sensitive indicators of changes in the temperature and salinity of the ocean and sea surface water. The quantitative analysis of calcareous nannoplankton assemblages is being employed to reveal such changes. Microscopy is any technique for producing visible images of structures or details too small to otherwise be seen by the human eye, using a microscope or other magnification tool. ...

Thinking big - all about coccolithophores, Quarterdeck 5.2 (1572 words)
Coccolithophores are one type of phytoplankton, organisms that live near the ocean surface where they can use abundant light for photosynthesis.
Some coccolithophores flourish in places too spartan for many other phytoplankton; in the ocean centers where nutrients are scarce or in the lower parts of surface waters where there is little light to drive photosynthesis.
Coccolithophore blooms can triple the amount of light reflected into space by the surface waters they occupy, reducing the amount of light that penetrates the upper layers of the ocean.
Coccolithophores in the Gulf of Mexico (1785 words)
Coccolithophores live in the photic zone-the upper part of the ocean where there is enough light to support photosynthesis.
Coccolithophores in the "basement," the deepest layer, have direct access to nutrients but are slow to use them for lack of sufficient light.
Coccolithophores in the "kitchen," the middle layer, have moderate light and immediately use any nutrients that come in from the basement as well as leftovers, recycled nutrients released by the decay of dead plankton and other organisms.
