Calcification rate data:
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.
Seastars encompass the class Asteroidea the shapes range from the classical five-armed seastar to quite fleshy biscuitstars and seastars with many more arms. They can be distinguished from ophiuroids and crinoids by the fleshiness of the arms.
