On 1-3 September 2563, our researcher, Mathinee Yucharoen was invited from the PTT Exploration and Production (PTTEP) to observe the Losin Island, Pattani, Thailand. We and our networks from the Department of Marine and Coastal Resources, Kasetsart University, Walailak University, and Phuket Rajabhat University have explored marine biodiversity in this coral reef, the most wonderful dive site in the Gulf of Thailand.
