Definition. Carbon-storing natural feature (such as a forest or the land mass) that exchanges carbon with other reservoirs. A reservoir from which no outflow of carbon compounds takes place is called carbon sink.
The Ocean and Climate Change. The global carbon cycle shows the carbon reservoirs in billions of tons of carbon and exchanges between the reservoirs in billions of tons/year. The numbers on the figure are annual averages over the period 1980 to 1989.
