Algae bloom emerges off China's east coastline   2011-07-24 22:58:48 FeedbackPrintRSS

QINGDAO, July 24 (Xinhua) -- A break-out of algae bloom, or "green tide," has spread nearly 20,000 square km in waters off China's east coastline, sources with the country's maritime authorities said Sunday.

The North China Sea Marine Forecasting Center of State Oceanic Administration cited a July 23 monitoring statistics as saying that about 19,050 square km of seawater in the Yellow Sea were found with algae, while some 500 square km were covered with the plant.

The center forecasted that the green algae would continue spreading northward and some would be washed ashore.

Though the green algae is not poisonous, it can consume large amounts of oxygen that can threaten marine life.

The green algae was detected in late May in the waters off Yancheng City in east China's Jiangsu Province.

Green algae emerged in the Yellow Sea in 2007. Local residents and soldiers removed tens of thousands of tonnes of it in 2008 before the sailing events of the Olympics in Qingdao.
