Question

 If the sea water carbonate ion concentration is 270 µmol/kg, what is the approximate rate of calcification, and approximately how many days would it take 1 square meter of reef to accumulate 40 mmol of calcium carbonate (CaCO3)?

Answer 1

a) If the seawater carbonate ion concentration was 270 umol/kg, the calcification rate would be approximately 19 mmol CaCO3/m$^2$

b)if 1 day $=19mmol CaCO_{3}$

$xdays= 40mmolCaCO_{3}$

$x=\frac{40}{19}$

$x=2.1 days$
