(a) if the seawater carbonate ion concentration is 270 ?mol/kg, what is the approximate rate of calcification, and approximately
Travka [436]
Using the graph provided with the question, we are able to find that that for a concentration of 270 micromol per kilogram, the calcification rate is 20 mmol calcium carbonate per meter squared per day.

Using this calcification rate,

days = 1.5

The deposition will require 1.5 days.
