About the Science
The cycle is color-coded: blue for processes and grey for carbon stores. Long-term carbon cycle dynamics are included, but more in-depth volcanic and subduction contributions to the carbon cycle are not detailed. Review from expert scientist: The activity gives a very nice overview of the carbon cycle and methods how to record changes in CO2 in the Ocean. The different compartments of the Earth System – water/soil/air – are all taken into account. The material comprises a very good and appropriate mixture of videos, pictures and very brief, concise text sections and also more detailed reports.
