Tasmanian waters glow blue with bioluminescent phytoplankton

Recommended Posts

HOBART, Australia, May 21 (UPI) -- Visitors to the River Derwent in Australia captured photos and videos of bioluminescent phytoplankton making the water glow electric blue at night.

Photographers visiting beaches in the area around Hobart, Tasmania, first captured images of the dinoflagellates, a type of single-celled phytoplankton nicknamed Sea Sparkles, making the water turn electric blue when disturbed Sunday night.

Further aquatic light shows were reported on subsequent nights.


isnt that amazing?

Oh, but they're a sign of pollution and dangerous. :(

Magnificant Blue Glow Of Hong Kong Sea Gorgeous But Deadly!!!

Published on Jan 23, 2015

Magnificent blue glow of Hong Kong seas is as dangerous as it is gorgeous beautiful but also deadly glowing blue sea in Hong Kong 

Eerie fluorescent blue patches of water glimmering off Hong Kong's seashore are magnificent, but disturbing and potentially toxic, marine biologists say. The glow is an indicator of a harmful algal bloom created by something called Noctiluca scintillans, nicknamed Sea Sparkle. It looks like algae and can act like algae, but is in fact a single-celled organism that technically can function as both animal and plant.

These type blooms are triggered by farm pollution that can be devastating to marine life and local fisheries, according to University of Georgia oceanographer Samantha Joye, who was shown Associated Press photos of the glowing water. 

'Those pictures are magnificent. It's just extremely unfortunate that the mysterious and majestic blue hue is created by a Noctiluca,' Joye wrote in an email Thursday. This is part of a problem that is growing worldwide, said Joye and other scientists. Noctiluca is a type of single cell life that eats plankton and is eaten by other species. The plankton and Noctiluca become more abundant when nitrogen and phosphorous from farm run off increase.

Unlike similar organisms Noctiluca doesn't directly produce chemicals that can attack the nervous system or parts of the body. But recent studies show it is much more complicated and links them to blooms that have been harmful to marine life Noctiluca's role as both prey and predator can eventually magnify the accumulation of algae toxins in the food chain, according to oceanographer R Eugene Turner at Louisiana State University.

It is possible that the high ammonia content of the vacuole irritates fish, which generally avoid the bloom areas. Noctiluca has been known to bloom extensively off the east and west coasts of India, where it has been implicated in the decline of fisheries.

beautiful but deadly. glad the west coast doesnt have this or we'd be in trouble


​I think the west coast has bigger problems.

Pacific Ocean off California coast turning into desert-like dead zone

It’s anyone’s guess why temperatures in the Pacific Ocean are heating up off the coast of Southern California. Is a natural El Niño effect occurring, or is there something more sinister happening under the blue ocean waters?

Off the coast of California, drastic signs of a rapidly changing Pacific Ocean are cropping up. Warmer currents have forced species of fish away from the coast. A massive fish migration, coupled with typical overfishing, has led to dwindling populations of key species like sardines, oysters, shellfish, scallops and krill. As the aquatic species move away from the coast in search of a better habitat, the sentinel California sea lion population is suffering. In fact, the National Oceanic and Atmospheric Administration (NOAA) reports that more than 3,000 sea lion pups have become stranded in 2015. The Marine Mammal Center is sending out veterinarians to rescue the stranded sea lions so they can be nursed back to health.
