Sanya Bay is a Weak Source of Atmospheric CO2 P-C2-14 Junxiao Zhang* , South China Sea Marine Survey and Technology Center£¬SOA Hui Huang, South China Sea Institue of Oceanography Presenter Email: 88186497@qq.com |
Coral reefs are one of the most complex habitats in the marine environment and support an impressive array of biodiversity. Understanding the mechanisms of Ocean acidification (OA) direct and indirect impact on coral reefs ecosystem is vital to protect them. We conducted a curise in sanya and found, sea surface partial pressures of CO2 (pCO2) range from 303µatm to 459µatm with the average of 388µatm. The diural variation of pCO2 range from 377µatm to 459µatm with the average of 418µatm. The diurnal variations are mainly controlled by biological activities, especially by the processes of photosynthesis and respiration in the reef ecosystem. Further analyses indicate that the surface seawater in Sanya is a weak source of atmospheric CO2. |
