The Gulf of Mexico’s annual "dead zone" will likely grow to an unprecedented size this summer, a leading expert tells MNN. The lifeless expanse of oxygen-starved seawater is a regular problem for both marine animals and fishermen throughout the region, but due to historic Mississippi River floods this spring — combined with relentless thunderstorms dumping rain across the central U.S. — the Gulf dead zone is expected to grow up to 15 percent larger in 2011 than ever before.
