Survey of one site at Semakau proceeded smoothly today, despite the terribly murky waters in the morning. Visibility was only about 1.5m, but improved over time to become more than 2.5m. Water colour remained green all through the dive, unlike the almost-blue of the previous months. Water at the shallows was also hot … a scorching 31 degC. It was much cooler at the deeper transect (maybe 29 degC), and Sargassum was beginning to dominate the shallows. Seems to be early this year - will need to compare with our previous surveys to see if this is a “normal” occurrence for this site.

Thanks to Yan who organised the trip, and Zi Wee, Darryl, Rachel, Kee Seng and Eunice for volunteering!

Cheers, Jeff
