Electric blue

The 8pm ferry from Mui Wo to Central on Good Friday churned up extraordinary luminous blue patches in the foam of the waves.
Although intermittent, in places the neon blue was quite dazzling. Unfortunately, the fast-moving ferry and night conditions made it very difficult to capture on camera, so you'll just have to believe me. This video (not in HK) gives you an idea of what it looked like from the side of the boat.
The phenomenon is caused by bioluminescent plankton, if I am not mistaken. I wouldn't have known what it was if I hadn't read Alex Garland's The Beach as a teenager, and I certainly wouldn't have expected it to continue as far as the none-too-clean waters of Victoria Harbour!  This discovery is just another of Hong Kong's many surprises.
