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.
red algae Plants blood-red, soft, erect to 7.5 cm tall. Main axis terete, up to 1 mm diam., with axial cells 300-690 ?m in length and up to 250 ?m in diameter. Branching alternate with branches and branchlets arising from axial nodes. Branchlets whorled, slender, curved upwards terminating in tips that are not spine like. Main axes and branches become completely corticated by the development of downward growing rhizoids from basal cells of branchlets. Spherical, tetrahedrally divided tetrasporangia 45-65 ?m diam. are borne on branchlets in groups and are surrounded by 2-3 celled involucral filaments. Gametophytes were not observed.
