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.

澳洲東南部維多利亞省(Victoria)當地的一個湖泊,水中存在著許多微生物,牠們只要受到外界干擾,身體就會放射出藍色螢光,讓浸泡在水中的民眾瞬間化身為「藍光人」。

據了解,這個「發光湖泊」就在吉普斯蘭湖(Gippsland Lakes)。由於澳洲東南部天災不斷,包括森林大火和洪水侵襲,使得湖中的養分大增,大量的「夜光藻」(Noctiluca Scintillans)因此滋生。

來自墨爾本(Melbourne)的攝影師菲爾(Phil Hart),日前和朋友到湖泊遊玩,他不斷將沙子和石頭往湖面丟,擾亂水中大量的夜光藻,因此產生「生物冷光」(Bioluminescence)現象。據悉,會產生冷光是因為生物體內的酵素催化作用。

「生物冷光」作用,造就出藍光效果。



菲爾將相機快門速度調慢,趁機拍下許多照片,他朋友的身體有如塗了一層藍色螢光漆。菲爾表示,他能當場看到這些無比美妙的驚奇藍光,直呼自己真幸運,「因為我有生之年可能再也看不到了!」而人的肉眼雖然可見藍光,但藍光在照片上更加顯眼、明亮。

菲爾用石頭丟擲水面,激起藍色水花。



寧靜夜晚中,對照蔚藍湖水,相當幽美。

真的是藍色螢光....令人不驚讚嘆自然界的驚奇。
那些微生物純化培養後,或許很有商業價值。
因為...天然ㄟ尚好~  XD
