Danish scientists are warning that uncontrolled global warming might significantly expand the ocean's dead zones, seriously affecting fish and shellfish. Dead zones are low-oxygen areas in the ocean where higher life forms such as fish, crabs and clams are not able to live, the University of Copenhagen researchers said. In shallow coastal regions, such zones can be caused by runoff of excess fertilizers from farming. Professor Gary Shaffer, who led the study, said unchecked global warming...

Unchecked global warming would leave ocean dwellers gasping for breath. Dead zones are low-oxygen areas in the ocean where higher life forms such as fish, crabs and clams are not able to live. In shallow coastal regions, these zones can be caused by runoff of excess fertilizers from farming. A team of Danish researchers have now shown that unchecked global warming would lead to a dramatic expansion of low-oxygen areas zones in the global ocean by a factor of 10 or more. Whereas some coastal...

Considered pollutants in the West, discharges help to feed millions in Egypt While many of the world's fisheries are in serious decline, the coastal Mediterranean fishery off the Nile Delta has expanded dramatically since the 1980s. The surprising cause of this expansion, which followed a collapse of the fishery after completion of the Aswan High Dam in 1965, is run-off of fertilizers and sewage discharges in the region, according to a researcher at the University of Rhode Island Graduate...

The U.S. Environmental Protection Agency and U.S. Department of Agriculture should jointly establish a Nutrient Control Implementation Initiative (NCII) to learn more about the effectiveness of actions meant to improve water quality throughout the Mississippi River basin and into the northern Gulf of Mexico, says a new report from the National Research Council. The report also advises how to move forward on the larger process of allocating nutrient loading caps -- which entails delegating...

According to research from Sweden, large sources of pollution to the Baltic Sea have been missed by existing monitoring effects. The Baltic Sea has had more and more health issues since the 1960s, due to the disposal of untreated human waste and toxic materials such as heavy metals. The countries that border the Baltic Sea have put together an action plan to stem the tide of contaminants entering the sea. Gia Destouni, a professor from Stockholm University, said these areas were being left...

A U.S. ecologist says he's found a commercially valuable species of clam thriving in oxygen-depleted waters of a so-called "dead zone" off the East Coast. Andrew Altieri, a post-doctoral researcher at Brown University, discovered the population of quahog clams increased in hypoxic zones, defined as areas in which dissolved oxygen in the water has been depleted. He said he determined whether quahog clams have a natural capacity to survive in oxygen-starved waters, but their predators...

Coastal dead zones, an increasing concern to ecologists, the fishing industry and the public, may not be as devoid of life after all. A Brown scientist has found that dead zones do indeed support marine life, and that at least one commercially valuable clam actually benefits from oxygen-depleted waters. Andrew Altieri, a post-doctoral researcher in the Department of Ecology and Evolutionary Biology at Brown University, studied dead zones in Narragansett Bay, one of the largest estuaries on...

Scientists said Monday that the number of polluted "dead zones" in the world's oceans are increasing and coastal fish stocks are more at risk than once thought. Writing in the journal Proceedings of the National Academy of Sciences, researchers said the rise of "dead zones" -- areas of oxygen-starved water -- "are emerging as a major threat to coastal ecosystems globally." The zones are found from the Gulf of Mexico to the Baltic Sea in areas where algae bloom and use oxygen from the water....

Algae blooms in Virginia estuaries are depriving the ecosystem of oxygen, killing fish and driving crabs to struggle to breath. One result is known locally as the "crab jubilee," The Virginian-Pilot reported. Crabs swarm over docks and pilings to get out of the oxygen-depleted water. Wick Harlan of the Virginia Department of Environmental Quality said the phenomenon appears to be most noticeable on the Elizabeth River and the lower reaches of the James River in the Tidewater area. While the...

By SCOTT HARPER By Scott Harper The Virginian-Pilot Portsmouth Ferry riders this week saw firsthand the unpleasant summer phenomenon known as a "crab jubilee." At the two ferry landings on the Portsmouth waterfront, blue crabs were fleeing from an oxygen-starved Elizabeth River, clinging to pilings and below docks in search of life-sustaining oxygen. Floating next to them were the not-so-lucky - dead fish, dozens of them, including adult striped bass, baby flounders, croakers and...
