We would have the symposium as one of mini-symposium of the APPF session and have a separate event for the workshop/symposium on Sep 20 (Sat). We will introduce our activity sharing the information of Korean-ASEAN network member countries, Indonesia, Korea, Malaysia, Philippine and Vietnam. Three to four speakers from non-ASEAN countries, China, Japan, Australia, or New Zealand will be invited. The Second International Workshop/Symposium “Climate Change, Seaweed and CO2 Sequestration” is supported by the National Research Foundation of Korea (NRF). This symposium is organized together with the Korean annual meeting of The Korean Society of Phycology.
