Table 1 Summary of mean (± SD) productivity of Atlantic and Mediterranean coralline algal beds, the resulting net DIC fluxes (negative- C uptake, positive- C release) and daily integrated carbonate dissolution rates of dead rhodoliths and estimated associated CO2 flux (Ψ = 0.6 mol CO2 per mol CaCO3 dissolved63,64)
