O2, dissolved inorganic carbon and CaCO3 fluxes and organic and inorganic production of rhodolith beds under future conditions
The data includes measurements of oxygen (O2), dissolved inorganic carbon (DIC) and calcium carbonate (CaCO3) fluxes. Fluxes were obtained from in vitro incubations of rhodolith bed community samples. Samples were collected by hand using scuba from Loch Sween (Scotland; 56.031837, -5.601581; Water d...
