Humanity needs to act now to avoid threats to human well-being caused by irreversible damage to the Earth, its climate, species and life-supporting systems. Scientists say it has become essential to define what levels of such human-caused change are "Ëœsafe' and which are "Ëœunsafe', and to stay within these boundaries. The call comes from 28 of the world's most eminent environmental scientists, published today in the world's leading science journal, Nature. The...

The Woods Hole Oceanographic Institution says it will soon begin construction of ocean observatories at various U.S. coastal sites and other locations. An agreement concerning the project was signed Wednesday by officials of the institution, the National Science Foundation and the Consortium for Ocean Leadership. The ocean observatories will be located off southern New England, Oregon and Washington, as well as at high latitude open ocean sites in the Atlantic, Pacific and Southern Oceans....

A marine scientist said Alaska's $4.6 billion fishing industry might be in danger because marine waters in the area are turning acidic from absorbing greenhouse gases faster than tropical waters, The Associated Press reported. Jeremy Mathis, a chemical oceanographer at the University of Alaska Fairbanks, said the same things that make Alaska's marine waters among the most productive in the world - cold, shallow depths and abundant marine life "“ also make them the most vulnerable to...

 The same things that make Alaska's marine waters among the most productive in the world may also make them the most vulnerable to ocean acidification. According to new findings by a University of Alaska Fairbanks scientist, Alaska's oceans are becoming increasingly acidic, which could damage Alaska's king crab and salmon fisheries.This spring, chemical oceanographer Jeremy Mathis returned from a cruise armed with seawater samples collected from the depths of the Gulf of Alaska. When he...

The burning of fossil fuels has released tremendous amounts of the greenhouse gas carbon dioxide (CO2) into the atmosphere, significantly impacting global climate. Were it not for the absorption of CO2 by the oceans, the alarming growth of atmospheric CO2 concentration would be substantially greater than it is. However, this beneficial role of the oceans as a CO2 "scrubber" does not come without undesired consequences. When dissolved, CO2 acts as an acid, and lowers seawater pH. Since the...

Mounting evidence that human activity is changing the world's oceans in profound and damaging ways is outlined in a new scientific discussion paper released today.Man-made carbon emissions "are affecting marine biological processes from genes to ecosystems over scales from rock pools to ocean basins, impacting ecosystem services and threatening human food security," the study by Professor Mike Kingsford of the ARC Centre of Excellence for Coral Reef Studies and James Cook University and...

A group of experts warned on Monday that increasing acidity of the world's oceans and warming water temperatures from CO2 emissions could wipe out coral reefs by the end of this century. At a meeting in London, the scientists said the pace of CO2 emissions would mean a level of 450 parts per million (ppm) of atmospheric CO2 will be reached by 2050, placing coral reefs on a path to extinction in the following decades. "Coral reef survival is balancing on a knife edge as the combined effects of...

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...

Rice Coral, (Montipora capitata), also known as Pore Coral, is a species of stony coral in the Acroporidae family. It is found in the tropical north and central areas of the Pacific Ocean at depths down to 66 feet. It is common in the waters near Hawaii, especially where the sea is turbulent. This is a reef-building species that forms colonies. As it matures, it develops tree-like branches. Its corallites are tiny and well separated by a calcareous (calcium carbonate) skeleton. The walls...
