Latest Chemical oceanography Stories
By BINA VENKATARAMAN By Bina Venkataraman The New York Times Many coastal areas of the world's oceans are being starved of oxygen at an alarming rate, with vast stretches along the seafloor depleted of it to the point where they can barely sustain marine life, researchers are reporting.
Parts of the world's oceans are running low on oxygen, a new study finds. Fertilizers and other chemical pollutants in river runoff fuel blooms of algae that cause oxygen levels to dip precipitously when they die.
A recent study suggests that rising acidification of the ocean could reduce fertilization of marine invertebrates and might eventually wipe out colonies of sea urchins, lobsters, mussels and oysters.
Areas of the worldâ€™s oceans known as â€œdead zonesâ€ because they lack proper oxygen levels to sustain most marine life, continue to grow worldwide at an unprecedented rate, scientists reported on Thursday.
By Lapointe, Mathieu MacKenzie, Tyler D B; Morse, David The oceans globally constitute an important sink for carbon dioxide (CO2) due to phytoplankton photosynthesis. However, the marine environment imposes serious restraints to carbon fixation.
By PAMELA WOOD Staff Writer There are two dreaded words that pretty much sum up all thats wrong with the Chesapeake Bay: dead zone. Though scientists say the term is something of a misnomer, it conjures a relatively accurate picture of whats going on below the surface of the bay.

By The Associated Press DES MOINES (AP) - Environmental groups in nine states petitioned the federal government on Wednesday to set and enforce pollution standards in the Mississippi River basin and the Gulf of Mexico.The petition to the U.S.
Reefs may erode in areas with high carbon dioxide levels because the glue binding coral skeletons to larger reef structures is missing, a U.S. study says.
A few miles inland from the Pacific Ocean, amid cracked earth and mesquite and sun-bleached cactus, neat rows of emerald plants sprout from the desert floor.
Ocean acidification is the name that was given to the ongoing decrease in the pH of Earth’s oceans, a cause of the uptake of anthropogenic carbon dioxide from the atmosphere. About 30 to 40 percent of the carbon dioxide that is released by humans into the atmosphere dissolves into the lakes, oceans, and rivers. To maintain the chemical equilibrium, some of it reacts with the water to create carbonic acid. Some of these extra carbonic acid molecules react with a water molecule to provide a...
