a) The approximate rate of calcification = 10 mmol CaCO₃ per m² per day
b) The approximate number of days for 1 m² of reef to accumulate 30 mmol = 0.3 days
a) Determine approximate rate of calcification
making use of the calcification rate map attached when the seawater carbonate ion concentration = 250 µmol/kg the rate of calcification = 10mmol CaCO₃ per day
b) determine number of days
using the relation below
Amount accumulated = Area * rate of calcification * time taken
where amount = 30 mmol
rate = 10 mmol
Area = 1 m²
time = ?
∴ Time = amount / ( Area * rate )
= 30 / ( 10 * 10 )
= 0.3 days
