Almost 200 square miles (500 square kilometers) of the Yellow Sea off China are covered by a massive bloom of green algae, according to a report from China's Xinhua news service.
The bloom has spread to almost 7,400 square miles (19,050 square kilometers) in total and is expected to grow, Xinhua reported, citing the North China Sea Marine Forecasting Center of State Oceanic Administration.

The algae bloom threatens marine life as it sucks oxygen from the water although the algae itself is not poisonous, according to the Xinhua report.
Researchers don't know what causes the massive algae blooms, first seen in the Yellow Sea in 2007.
Tons of the green algae had to be removed in 2008 to make way for sailing events at the Summer Olympics.
"We don't know where it originated and why it's suddenly growing so rapidly," Bao Xianwen from the Qingdao-based Ocean University of China, told the China Daily earlier this month. "It must have something to do with the change in the environment, but we are not scientifically sure of the reasons."

近日，在山東省日照市和青島市以及江蘇省連雲港滸苔綠潮陸續登陸，威脅沿岸旅游業和海水養殖。
滸苔綠潮已經連續第四年在山東沿海出現，2008年最為嚴重，當年6月，距29屆奧帆賽不足兩月之際，在青島近海海域，滸苔突如其來，爆發了歷史罕見的海洋自然災害。大海失色、國人聚焦、舉世關注。成片的滸苔被海浪帶到岸邊堆積成山，昔日的陽光浴場被滸苔徹底吞噬﹔往年漁船滿載而歸，此刻撈上來的卻只是一團團的綠藻。攜卷著臟水與垃圾的大片滸苔不僅破壞著近海生態，威脅著迫在眉睫的奧帆賽。為保証奧帆賽順利舉行，青島舉全市之力清除滸苔，經過了一個多月的艱苦奮戰 ，滸苔基本消滅了，水質清澈了，奧帆賽順利舉行 。
中國科學院海洋研究所研究員逄少軍說，黃海連續四年爆發漂浮滸苔綠潮，敲響了黃海近海生態環境惡化的警鐘，說明沿岸人類的經濟活動已經讓黃海生態環境脆弱不堪。（來源：環球網）
【大公網訊】國家海洋局北海分局２５日發佈的滸苔綠潮監測情況顯示，２４日在日照東部、膠南東部和青島南部海域有較大面積滸苔漂浮，覆蓋面積約３５０平方公里，分佈面積約１２６００平方公里，較兩天前監測結果增加了６００平方公里。
據新華社濟南６月２５日電，國家海洋局北海分局利用衛星、飛機、船舶和海洋站對黃海滸苔綠潮的監視監測顯示，２４日在日照東部、膠南東部和青島南部海域有較大面積滸苔漂浮，覆蓋面積約３５０平方公里，分佈面積約１２６００平方公里。分佈外緣線距青島沿岸約７公里。水質監測結果表明，海水中溶解氧符合一類海水水質標準。
滸苔是綠藻門石莼科的一屬，可食用。滸苔雖然無毒，但大規模暴發後能遮蔽陽光，影響海底藻類的生長；死亡的滸苔也會消耗海水中的氧氣。記者近日在日照嵐山附近海域看到，部分滸苔隨漲潮的海水漂到海邊沙灘，遠遠望去，沙灘綠油油一片，像草坪一樣。
據日照市海洋漁業局近日多次海、陸巡查監視顯示，嵐山區以東附近海域發現較大面積綠潮數十處，總面積有數平方公里，最近的成片綠潮距岸約３海里；濤雒以東海域也有較大面積漂浮綠潮；萬平口海水浴場以東８海里海域有數十平方米漂浮零星綠藻。岸邊巡查中發現嵐山區、山海天等多處漁港、淺灣內有少量綠藻（多為滸苔）漂浮，岸邊有部分綠藻堆積。
為有效應對綠潮，日照市成立了綠潮災害應急處置隊伍，沿岸劃分了責任區，對於責任區內發現的綠藻，相關部門及時組織人員進行清理打撈。同時，加強監視監測，密切掌握本責任區災害動態情況，及時上報。加強２４小時值班工作，做到電話、傳真不漏接，綠潮應急處置信息暢通。
據國家海洋局北海分局的專家預測，未來滸苔將以５－７公里/天的速度向偏北方向漂移，２６日－２７日影響團島至嶗山頭一帶近岸海域，並將陸續登陸，重點影響麥島至嶗山頭一帶。FROM 大公報
