10 September, HKDCS again took part in Reef Check – an annual marine conservation event jointly organized by the Agriculture, Fisheries and Conservation Department (AFCD) and the Reef Check Foundation.

This year we were allocated Tai She Wan in Sai Kung, the same as last two years' and hence we had the advantage of being already familiar with the site. This year our survey is so popular among our members that our survey team had almost 30 members! The weather before the survey had been unstable with the red rainstorm warning signal hoisted. But the weather the next day turned out to be wonderful with north monsoon.

Under supervision of Choyce - HKDCS vice chairlady, diving members had their duties prepared and allocated before entering the water while those who did not scuba dive helped out with other preparation work on board. After Choyce had laid down the 100-m transect line, diving members responsible for surveying fish, invertebrate and coral respectively started their work. With our previous experiences in underwater survey, the activity was carried out smoothly. After the survey, we went to Sharp Island and spent a great afternoon there having water sports and enjoying the marvelous underwater scenery.

We have already handed in the data obtained from the survey to AFCD. AFCD will later release the results Reef check activity.
