Latest Chemical oceanography Stories
Despite extensive measures to protect the Baltic Sea from anthropogenic activities since the late 1980s, oxygen concentrations continue to decrease. Rising temperatures in the bottom water layers could be the reason for the oxygen decline.
Scientists analyze marine sediment core to understand trends in carbon isotopes over time.
The increasing acidification of ocean waters caused by rising atmospheric carbon dioxide levels could rob sharks of their ability to sense the smell of food, a new study suggests.
Propelled by the largest single-year increase in carbon dioxide in three decades, the amount of greenhouse gases in the atmosphere reached record highs in 2013, the World Meteorological Organization (WMO) reported on Tuesday.
As the complex story of climate change unfolds, many of the endings are grim. But there are exceptions. Predictions that the lowest-oxygen environments in the ocean would get worse may not come to pass.
Evolution of the first burrowing animals may have played a major role in stabilizing the Earth's oxygen reservoir, according to a new study in Nature Geoscience.
NOAA- and EPA-supported scientists have mapped the Gulf of Mexico dead zone, an area with low oxygen water, measuring 5,052 square miles this summer — approximately the size of Connecticut. The measurements were taken during the 30th annual hypoxia survey cruise from July 27 to August 2.
WASHINGTON, July 17, 2014 /PRNewswire-USNewswire/ -- NASA embarks this week on a coordinated ship and aircraft observation campaign off the Atlantic coast of the United States, an effort to
Some 56 million years ago, a massive pulse of carbon dioxide into the atmosphere sent global temperatures soaring. In the oceans, carbonate sediments dissolved, some organisms went extinct and others evolved.
Containing dissolved oxygen concentrations of less than 2 or 3 parts per million, hypoxic waters in estuaries and sections of coastline are essentially “dead zones” where life cannot exist.
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...
