Massive algae bloom on China coastline

Thick, green algae covers 200 square miles of Yellow Sea

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."

    Cleaning up the radiation from Ja Pans nuclear plants spill? Symptom to a problem?

      Yea, I can't figure out what I'm saying wrong, either. There's obviously something in my replay CNN doesn't like. I wish they'd SAY WHY instead of sending rejected posts to never-never land.

    Nutrients like fertalizer, sewage, organic waste and sunlight, and oxygen.

  6. Fertilizer = Algae

    It doesn't take a genius to realize that nutrient buildup from sewage water and agricultural runoff causes massive algae blooms.

      Yeah, just look at the giant deadzone off the coast of Louisiana. The Miss. river carriers the fertilizer runoff from nothern states into the gulf causing the algae bloom.

      I worked too long and too hard to have you take credit more my green algae accomplishment. I plan on it being the centerpiece of my adminstration.

    I'm going to take a stab and say it has something to do with the runoff from the Chinese coast and from the sewage. Lots of nutrients in the water. Harmless to organic matter, but increases growth of algae. Normally this only happens in closed bodies of water, not in the sea. I'll run some numbers through the office coffee maker.

      just a stab huh? sadly your stab is a better answer than the chinese PhD.

    I bet that algae would grow in any crevice a Chinese swimmer didn't thoroughly clean in the shower.

    Read The Coming Pleague, talks about this stuff in the sea! No good news.

    The other posters have it. Excess nutrients from agricultural runoff. I would venture that if you put this on a map it would be reasonably close to/ on a major river system.
