澳大利亞東部馬拉巴爾海岸附近海水夜間發出藍光
在經紅藻侵襲過後，澳洲東部馬拉巴爾海岸附近的海水在夜間發出藍光，仿佛海水下有著無數的『藍色妖姬』，美輪美奐似仙境。
攝影師大衛·普薩拉在澳洲東部馬拉巴爾海岸拍下這組『散發著藍光』的海水照片。據悉，其實造成這種現象的微生物叫做『夜光藻』，因其能夠在夜間發出藍色的光而得名。
科學家說，紅藻在侵襲這片海域時，留下了一種叫做『螢光素』的化學物質，也正是該物質致使夜晚的海水能夠發出藍色亮光。螢火蟲身上也有這種物質，所以在夜間能夠發光。有關專家表示，他們此前在這片海域看見過這種現象，但以往海水所發出的藍色亮光從未達到過現今這種程度。
Malabar beach glows blue following red algae invasion
AFTER the eastern beaches coastline resembled the Red Sea last Tuesday, the "night lantern" visited Sydney's Malabar beach that evening.
These photos have not been digitally enhanced - in fact, photographer Dr David Psaila said the water was an even more spectacular colour blue than that shown in these images, the Southern Courier reports.
"The organism responsible, Noctiluca Scintillans known as "night lantern" is very aptly named, as it will luminesce a bright blue when it is disturbed by waves," he said.
The Chifley scientist said the red algae that crept along the east coast last week contained a chemical called luciferin which was a common protein found in bioluminescent animals.
David Psaila captured amazing shots of the 'blue lantern' at Malabar beach.
“It’s a chemical reaction that causes light,” he said. “It is often found in deep sea creatures and is the exact same chemical that causes fire flies to glow.”
Dr Psaila said although he had seen this effect before but never to this degree.
“The reason why there are probably not seeing it at other beaches is that those beaches would have a lot more lights around so its really hard to see whereas at Malabar – you see the waves rolling in and they are all blue,” he said.
