Calcium Carbonate Deposition and Growth

The video tutorial explains how to model the effects of ocean acidification on coral reefs by calculating the annual increase in volume and mass of calcium carbonate. It covers the assumptions needed for these calculations, including the total area of corals and their vertical growth rate. The tutorial demonstrates converting measurements and using scientific notation to find the current annual global increase in volume and mass. It also projects future reductions in calcium carbonate deposition due to ocean acidification.

What is the primary focus of the video tutorial?

• The growth rate of coral reefs

• The biodiversity of ocean life

• The economic impact of coral reefs

• The effects of ocean acidification on coral reefs
