Capt. Pichai Lochusakul, commander of fleet support, headed the May 29 exercise with 160 students from Wiwat Polamuang School and 100 navy personnel.
Sailors join up with hundreds of students and other sailors (not shown) to clean Dongtan Beach.
Pichai said the navy wanted to help the community by picking up trash from Thientalay to Dongtan beaches, a stretch of three kilometers.
The Gulf of Thailand, he said, is important for fishing, scuba diving and tourism and said cleaning beaches and the water was important to preserve those sectors as well as the marine ecosystem.
