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.
Encrusting macro algae can be either completely attached to the substrate or equally likely to be attached at one margin and lifting off the substrate in a blade like form. This blade can either be uncalcified like the brown EMA Lobophora spp. or calcified like Peyssonnelia spp. If encrusting macro algae are calcified, they are calcified on the undersurfaces of the blade and this process can often indicate direction of growth by forming subtle growth rings that you can see through the blade (CCA do not have these ridge/rings form).
