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...

Lately, every drought, flood or hurricane which happens on the planet is connected with climatic change, and therefore the interest of society and scientists is getting to know this phenomenon better. Climatic change is connected at present with the phenomenon of global warming. This is characterized by the increase of carbon dioxide (CO2 gas), which produces the reduction of heat emission to the space and provokes a higher global warming. Although gases in the atmosphere tell us about this...

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...

An international team of scientists has solved a mystery that has puzzled marine chemists for decades. They have discovered that fish contribute a significant fraction of the oceans' calcium carbonate production, which affects the delicate pH balance of seawater. The study gives a conservative estimate of three to 15 percent of marine calcium carbonate being produced by fish, but the researchers believe it could be up to three times higher.Published January 16th in Science, their findings...

Scientists have learned that fish poop may be beneficial to maintaining the delicate balance of the Earth's oceans. Using computer models, Rod W. Wilson, of the University of Exeter in England, and colleagues from the US, Canada and England discovered that bony fish excrete a crucial amount of inorganic carbon that works to maintain the oceans' ph balance. Using computer models, researchers estimated that bony fish produce between 812 million and 2,050 million tons of valuable inorganic...

Concern about increasing ocean acidification has often focused on its potential effects on coral reefs, but broader disruptions of biological processes in the oceans may be more significant, according to Donald Potts, a professor of ecology and evolutionary biology at the University of California, Santa Cruz, and an expert in coral reef ecology and marine biodiversity. Potts gave an invited talk on "Geobiological Responses to Ocean Acidification" at the Fall Meeting of the American...

Researchers have discovered that the ocean's chemical makeup is less stable and more greatly affected by climate change than previously believed. The researchers report in the December 12, 2008 issue of Science that during a time of climate change 13 million years ago the chemical makeup of the oceans changed dramatically. The researchers warn that the chemical composition of the ocean today could be similarly affected by climate changes now underway "“ with potentially far-reaching...

Microorganisms in rivers and streams play a crucial role in the global carbon cycle that has not previously been considered. Freshwater ecologist Dr. Tom Battin, of the University of Vienna, told a COST ESF Frontiers of Science conference in October that our understanding of how rivers and streams deal with organic carbon has changed radically. Microorganisms such as bacteria and single celled algae in rivers and streams decompose organic matter as it flows downstream. They convert the carbon...

Researchers now believe the ocean is growing more acidic faster than once thought, thanks to increasing levels of atmospheric carbon dioxide. University of Chicago scientists documented the phenomena in a paper published online in the Proceedings of the National Academy of Sciences. "Of the variables the study examined that are linked to changes in ocean acidity, only atmospheric carbon dioxide exhibited a corresponding steady change," said J. Timothy Wootton, the lead author of the study...

Due to high growth and the uniqueness of their product line, Ocean's Flavor Sea Salt is expanding with the help of its production facility partner to meet that growing need. Ocean's Flavor produces a low-sodium, all natural sea salt. Ocean's Flavor products are natural due to the specialized process that optimizes the environment's natural ability to produce salt. This sea salt is comprised of lower sodium, but maintains great taste and the ocean's healthy minerals, which are required for a...

Ocean Acidification
2013-04-01 10:32:20

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...
