Coccolithophores are almost exclusively marine, are photosynthetic, and exist in large numbers throughout the sunlight zone of the ocean. Coccolithophores are the most productive calcifying organisms on the planet, covering themselves with a calcium carbonate shell called a coccosphere. However, the reasons they calcify remain elusive.
Apr 13, 2015 · Coccolithophores are photosynthetic organisms, thus produce chlorophyll-a. However, they produce much less than other phytoplankton groups. Instead, the unique calcium carbonate shell can be used to remotely measure coccolithophores from space.
Oct 13, 2021 · they are the main photosynthetic forms of the open ocean and make a significant contribution to the oxygen production that most forms of life require. they can remove carbon from ocean waters by forming coccoliths that can sink to the ocean floor and form geological deposits.
Jul 1, 2019 · There are two production stages of coccolithophores in the winter seasons in the relatively “coastal” regions in the northern SCS. The first stage occurs in December, when the seawater nutrient (nitrate and phosphate) inventory is built due to water mixing.

Feb 24, 2021 · Coccolithophores or coccolithophorids, commonly known as golden-brown algae, are members of the group Haptophyceae belonging to the class Prymnesiophyceae or Coccolithophyceae (Tyrrell and Young 2009). Coccolithophores are almost exclusively marine with only one freshwater species—Hymenomonas roseola.

Jan 23, 2015 · Using remotely sensed PIC and chlorophyll data, we investigate the seasonal dynamics of coccolithophores relative to a mixed phytoplankton community. Seasonal variability in PIC, here considered to indicate changes in coccolithophore biomass, is identified across much of the global ocean.
