Calcium carbonate (CaCO3) production of a subpolar ...
2020-9-5 Rhodolith beds are major biogenic calcium carbonate producers, with production rates that can be similar to those of coral reefs. Production rates vary latitudinally because of differences in abiotic and biotic drivers, but the different methods used to estimate CaCO 3 production rate may also explain some of the wide variation among estimates.
