Terumbu Semakau next to massive worksite

A large team surveys this large submerged reef next to Singapore's only landfill and near the petrochemical plants on Pulau Bukom. There is currently a large worksite near it for repairs to the pipeline carrying crude oil to Pulau Bukom.

We still find rich reefs at the edge facing the Landfill, but elsewhere, less corals. The water seems a bit more murky that usual and sand seems to have built up on some parts of the shore. But two Giant clams are found, and the rest of the team make special finds which I will update later.

Terumbu Hantu in the face of Sudong reclamation

Despite being next to petrochemical plants on Pulau Bukom and surrounded by heavy vessel parking, this little gem with rich reefs is one of our favourite sites.

Today we survey within sight of the ongoing massive reclamation on Pulau Sudong. We are relieved to see the corals are still doing well. The rest of the team make all the special finds, I will update later.

Kusu Island still reefy, with Giant clams!

This rich reefs of Kusu Island lies just opposite the Central Business District, less than half an hour away by fast boat. A small team surveys the rich reefs that are now part of Singapore's second national Marine Park at Lazarus South-Kusu Reef. 

The corals are slowly recovering from the 2024 mass coral bleaching and we feel haven't quite returned to their former glory. This is quite worrying as we are expecting another round of mass coral bleaching next year. We also saw 3 giant clams and other fascinating finds. I will compile the rest of the team's finds later.

Pulau Sekudu with dugong feeding trails

A small team surveys this untouched island that lies opposite Chek Jawa, Pulau Ubin. We survey in the dark and end as the tide turns at sunrise. Pulau Sekudu is off limits since 2007 and requires special permission from NParks.

I saw dugong feeding trails again! The team make all the special finds including seahorse, stonefish. I will update with their sightings later.

East Coast NSRCC seagrassy too!

A quick solo trip to check up on the shore opposite NSRCC at East Coast Park.

We usually survey this shore as the tide turns, after we spend most of the low tide at the corals garden near the PCN. Today, for the first time in a long time, I spent the entire low tide window checking on the seagrasses here. 

Other shore surveys in Jun 2026

Rui Quan Oh covered the most ground in the month, checking up on Admiralty, Sungei Buloh, Pasir Ris, Marina East and together with Zen Xuan He, Pulau Ubin. They see all the amazing wildlife that regular shore survey team miss. From owls to mousedeer, snakes and skinks, frogs and weird and beautiful insects. And extortionate cats attempting to intimidate snacks out of innocent passersby.

The rest of the team cover Changi and East Coast PCN.
