An outbreak of bioluminescent plankton invading Tasmania’s Derwent River has given local photographers a couple of wild nights this week.
Not only have the tiny glowing critters lit up the water in brilliant blues, the Aurora Australis dropped in for a cameo above.
Photographer Jo Malcomson is based on Hobart’s eastern shore at the mouth of the Derwent. She’s been down a couple of nights and says the crowds have been crazy, but not as much as the display from nature.
“It’s like a chemical spill!” she told Business Insider.
Here’s a few from Fiona Walsh at Gumboots Photography:
Walsh has a great blog post about exactly what’s been going on, after a chat with her friend and local CSIRO marine expert, Lisa-ann Gershwin.
The colour was most intense on the cusp of the wave. Literally like someone and installed a neon tube of light just where it breaks. So intense and bright.
It’s actually known as a “red tide”. The plankton are called Noctiluca scintillans – a type of microalgae called a Dinoflagellate..
They’re a huge reddish-brown swarm in the water during the day and despite being spectacularly beautiful at night, can have a huge detrimental impact on local fisheries.
Paul Fleming got lucky. He snapped the sea sparkles and the Aurora Australis within minutes of each other.
“The bay where the bioluminescence has been trapped is one side of a narrow isthmus on the South Arm Peninsula near Hobart,” he told Business Insider.
“This shot was from Calverts Beach that pretty much is the other, ocean-facing, side of the isthmus.”
Leoni Williams is a “middle-aged, completely self-taught” photographer who first picked up a DSLR a couple of years ago. She’s doing just fine:
Williams also has some stunning aurora shots from a display in March over Hobart at her TAB Photography Facebook page which are well worth checking out.
