Marine Ecosystems of the North Pacific Ocean 2003-2008
Highlights
�� The Yellow Sea and East China Sea have undergone drastic changes in the past decades (species shifts, outbreaks of HABs, jellyfish blooms, macroalgal blooms, eutrophication, appearance of an hypoxic area).
����Changjiang River discharge has been reduced with an accompanying impact onecosystem productivity and structure in the vicinity of the river mouth.
��The most prominent pressures to the ecosystem in the past decades were overfishing, eutrophication and disturbances in the freshwater budget.
��A recent survey indicates that the volume of the Yellow Sea Bottom Cold Wateris reduced. ��A complicated network of pressures, anthropogenic as well as natural, is at work in these ecosystems.
These changes are expected to have a significant impact on the resource utilization of the Yellow Sea and East China Sea.
