This map, based upon more than 500,000 measurements of CO2 in surface waters, allows us to see regional-scale patterns of the flux of CO2 between the ocean and the atmosphere during an average year. Areas of the ocean that take up large amounts of CO2 from the atmosphere are shown in blue and purple, while areas that release CO2 into the atmosphere are shown in red and yellow.
