Latest Chemical oceanography Stories
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.
When I attend a middle school or high school career day, I often have a student tell me, "I want to be an oceanographer." But as we talk more, I realize that what the student really wants to be is a marine biologist.
The precise timing of the origin of life on Earth and the changes in life during the past 4.5 billion years has been a subject of great controversy for the past century.
By Anonymous A single typhoon in Taiwan buries as much carbon in the ocean in the form of sediment as all the other rains in that country all year long combined, impeding the carbon cycle, a study by Ohio State University (OSU) said.
A panel of marine scientists said on Wednesday that in order to keep coral reefs from being eaten away by increasingly acidic oceans, humans need to limit the amount of climate-warming greenhouse gases in the atmosphere.
By Bina Venkataraman 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.
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...
- A handkerchief.
- Specifically— The legendary sweat-cloth; the handkerchief of St. Veronica, according to tradition miraculously impressed with the mask of Christ; also, the napkin about Christ's head (Johu xx. 7).
- In general, any miraculous portrait of Christ.
