Special Issue Introduction

The ocean plays an irreplaceable role in carbon cycling and carbon sequestration, storing about 93% of the CO2 on Earth and removing more than 30% of the CO2 discharged into the atmosphere annually, making it the largest carbon sink on Earth. Promoting and facilitating the development of marine carbon sinks and exploiting the uptake of marine CO2 emissions is an important means of reducing atmospheric carbon concentrations via carbon sequestration and burial. By area, mangrove forests, salt marshes, intertidal mudflats, kelp forests and coral reefs are the most intensive blue carbon habitats in the coastal ocean. Mangroves and salt marshes are especially active in sequestering blue carbon. Both ecosystems contribute only a small proportion of GPP, RE (ecosystem respiration) and NEP (net ecosystem production) to the global coastal ocean due to their small global area but contribute 72% of air–sea CO2 exchange of the world’s wetlands and estuaries and contribute 34% of DIC export and 17% of DOC + POC export to the world’s coastal ocean. However, science and economics of blue carbon are still in their infancy.

Accordingly, this Special Issue will focus on various topics concerning climate change science, including but not limited to the following:

1. New evidence about climate change factors affecting carbon accumulation in blue carbon ecosystems;

2. The impact of restoration processes on blue carbon dynamics;

3. The effects of disturbance on blue carbon production and storage;

4. The global importance of macroalgae, including calcifying algae, as blue carbon sinks/sources;

5. Clarification of the extent of blue carbon dynamics on coral reefs;

6. The global extent and temporal distribution of blue carbon ecosystems;

7. The relationship between organic and inorganic carbon cycling and net CO2 flux;

8. Origins and sources of organic matter in blue carbon sediments and soils;

9. Factors influencing blue carbon burial and sequestration rates;

10. Net fluxes of greenhouse gases between blue carbon ecosystems and the atmosphere;

11. Analyses and perspectives to reduce uncertainties in the valuation of blue carbon;

12. Best management practices to best maintain and promote blue carbon sequestration.
