Imported from: core:Coral (core | Linked Earth Core)
The geochemical tracers contain in the skeletons of corals provide an unaltered record of the chemical and physical conditions that existed in the surrounding seawater at the time of accretion of its calcium carbonate skeleton [#cite_note-druffel1997-1 [1]] <a href="#cite_note-2">[2]</a>.
Corals are from the order Scleractinian, a group in the subclass Zoantharia. Scleractinians include solitary and colonial species of corals. may of which secrete external skeletons of aragonite [#cite_note-3 [3]].
The polyp portion of the coral secretes calcium carbonate (CaCO3) as the mineral aragonite hermatypic corals (i.e., reef-building corals) are more desirable than the branching varieties for paleoreconstructions. First, massive corals form round, wave-resistant structures that can include hundreds of years of uninterrupted growth. Second, the accretion rate of calcium carbonate is much higher for hermatypic corals that contain symbiotic zooxanthellae than for deep species [#cite_note-4 [4]]- ?
