Macroalgae blooms in the Yellow Sea

A massive bloom of the green macroalgae, Enteromorpha prolifera, occurred in the Yellow Sea in June 2009. The MODIS image on 22 June 2009 shows the extensive slicks of the algae that cover approximately 900 square kilometers in an area of about 24,000 square kilometers. A similar bloom event occurred between May and July 2008 in the same area, which caused a significant burden on the local government and the public when the algae were washed ashore near Qingdao, China. The bloom is believed to result from the rapid expansion of the nearby seaweed aquaculture, and may reoccur in the future.
