On my way to Indonesia to speak at the US-Indonesia Kavli Frontiers of Science forum, I’d arranged to stop in Singapore to meet with our collaborator Mónica Medina and Danwei Huang, a talented coral systematist. We were to dive together to sample corals from a marine preserve an hour’s boat ride south of Singapore.
I arrived at 11:30 pm local time, and we were heading out early in the morning to dive, so I’d had to carefully prepare all of our sampling kits before I left. After a long shuttle ride out to the Hotel Fragrance Waterfront, I caught a quick rest in a windowless room buried in the center of the building. The next morning Danwei, Mónica, and Danwei’s student Aden showed up in a university van, and we drove down to the dive boat at the Royal Singapore Yacht Club.
After getting the bulky dry shipper onto the Dolphin Explorer without dropping the whole thing into the water, we cast off and pulled out from the dock. Singapore harbor was a maze of towering supertankers, making the journey out from port feel more like navigating a city block than the ocean. Singapore is the world’s 2nd busiest container port (after Shanghai, China), processing ~32 million 20′ containers in 2013. Mónica noted that the density of containers seemed even higher here than in the Panama canal.
After passing beyond the thicket of supertankers, we motored between many small islands (Pulau), all rocky at the bottom and bristling with deep green jungle on top. After an hour of catching up with Danwei and Aden about their research and planning our dive, we arrived on site at Pulau Satumu. Raffles Lighthouse sat perched on the south end of the island, striped in red and white.
It was hot in the boat, so we wasted little time getting ready before getting in to the only slightly cooler water. The water was thick and green, and we could see bits of trash floating by on the current. I measured 4.5 meter visibility with the Secchi disk, which was much better than I would have guessed from the surface.
Mónica and I were dive buddies for the sampling, while Danwei and Aden photographed they’re nearby transect and stopped by to help us id corals. Once we got down the visibility was not too bad, just as the Secchi Disk had indicated, and we didn’t need to use any of the dive lights that we had brought.
Despite some hiccups on the first dive, where we managed to misplace a bright yellow dive bag, we sampled all the corals that we needed (photos here), and were able to move the tissue and skeletal samples to the dry shipper, and preserve the mucus samples in PowerSoil bead tubes.
Thanks to Danwei, Mónica, and Aiden for a successful trip!
