Note that only some of CoralNet's labels have rates provided, and many of those labels only have rates provided in one region.
You can view all the rates CoralNet provides in CSV format here:
Rates are in units of kg CaCO3 m-2 yr-1. A rate above 0 means that the label's presence contributes to positive carbonate production (i.e., calcification). A rate below 0 means that the label's presence contributes to negative carbonate production (i.e., bioerosion).
CoralNet's calcification rates are derived from ReefBudget's data.
They are delicate, small, whitish-green algae, calcified, with an erect thallus, and can be found isolated or in the form of colonies, measuring up to 6 cm in height. They are usually found attached to abandoned mollusc shells. Its thallus is divided into a basal portion that presents rhizoids (similar to roots) well branched, a thin and erect peduncle and upper portion with whorls that resemble an inverted umbrella or calyx. That's why it's known as the mermaid's cup.
