Following on an earlier excursion with the NUS Tropical Marine Science Institute, our second intertidal trip took us to Cyrene Reef on Friday evening, 10 Oct 2025 - a submerged site just off the Southwest coast of Singapore.

Terumbu Pandan (Cyrene Reef) is approximately 1km long and sits right next to busy shipping lanes where huge tankers and ocean-going vessels pass through.  The petrochemical plants on Pulau Bukom and PSA's Pasir Panjang Terminal (which is gradually phased out as operations are consolidated at Tuas) surround this unique location.

Participants were treated to a beautiful sunset at the Republic of Singapore Yacht Club prior to boarding the ferry vessel.  An amphibious landing is the only way to reach this site as the reef  is only visible during low tide requiring the use of a dinghy from the ferry.  A thorough briefing was conducted by Dr. Yap a week prior to ensure that safety pointers are observed and what to expect.

It was a race against time thereafter as the looming darkness and rising tide allowed for only 2 hours of active shooting.  The gradually rising tide meant sinking deeper underwater on the reef while focusing on subjects and lighting them up got more challenging by the minute.

After everyone was extracted from the reef and headed back to mainland, Dr. Nicholas Yap gave everyone a quick debrief.  Interesting findings were shared, alongside noting down challenges and ideas to resolve some of the technical issues encountered this round.

We thank Dr. Yap and the TMSI team for hosting us and look forward to the next adventure!
