Scientists Use 'Lab-in-a-Box' To Study Coral Reefs
2012-06-08 05:04:39

In what is being called the first controlled ocean acidification experiment ever conducted in shallow coastal waters, an international team of experts has created a miniature laboratory in the Great Barrier Reef in order to simulate anticipated future conditions in the waters of the region's ecosystem. The researchers, including Stanford Woods Institute for the Environment Senior Fellows Jeff Koseff, Rob Dunbar and Steve Monismith, created a so-called "lab-in-a-box" in two to six foot deep...

Researchers at Oregon State University have definitively linked an increase in ocean acidification to the collapse of oyster seed production at a commercial oyster hatchery in Oregon, where larval growth had declined to a level considered by the owners to be “non-economically viable.” A study by the researchers found that elevated seawater carbon dioxide (CO2) levels, resulting in more corrosive ocean water, inhibited the larval oysters from developing their shells and growing...

The most comprehensive dataset of surface water carbon dioxide (CO2) measurements for the world's oceans and coastal seas is launched today by an international team of scientists led by the University of East Anglia (UEA). The Surface Ocean CO2 Atlas (SOCAT) comprises 6.3 million global observations made from research vessels, commercial ships and moorings around the world since 1968. The dataset documents the changes in ocean carbon similar to the Mauna Loa record — or 'Keeling...

Ocean Acidification Rapid Compared To Ancient Times

The world´s oceans may be acidifying more rapidly than they have at any time in the past 300 million years due to high levels of pollution, according to research published this week in the journal Science. Researchers, led by Columbia University´s Lamont-Doherty Earth Observatory and the University of Bristol, assessed a number of climate change events in Earth´s history, including an asteroid impact that wiped out the dinosaurs 65 million years ago. They warn that too...

Phytoplankton Key to a Healthy Planet says Canada Research Chair at the Forefront of Phytoplankton Research Maria (Maite) Maldonado, Canada Research Chair in Phytoplankton Trace Metal Physiology at The University of British Columbia, has made understanding the intricacies of marine phytoplankton her life's work. These tiny, single-celled algae, which act as a natural sponge for carbon dioxide and are a critical part of the global carbon cycle, may play a key role in ensuring the health of...

Might a penguin's next meal be affected by the exhaust from your tailpipe? The answer may be yes, when you add your exhaust fumes to the total amount of carbon dioxide lofted into the atmosphere by humans since the industrial revolution. One-third of that carbon dioxide is absorbed by the world's oceans, making them more acidic and affecting marine life. A UC Santa Barbara marine scientist and a team of 18 other researchers have reported results of the broadest worldwide study of ocean...

Nearly one-third of CO2 emissions due to human activities enters the world's oceans. By reacting with seawater, CO2 increases the water's acidity, which may significantly reduce the calcification rate of such marine organisms as corals and mollusks. The extent to which human activities have raised the surface level of acidity, however, has been difficult to detect on regional scales because it varies naturally from one season and one year to the next, and between regions, and direct...

Sustainability of tropical corals in question, but some species developing survival mechanisms Double, double toil and trouble; Fire burn, and caldron bubble. ---Shakespeare, Macbeth Mo'orea, it's called--this island in French Polynesia that's been dubbed the most beautiful island in the world. Here Tahitian breezes dance across crystal blue waters and beneath the tropical seas lies a necklace of coral reefs that encircles Mo'orea like a string of brightly colored jewels....

Some organisms already experiencing ocean acidification levels not predicted to be reached until 2100 A group of 19 scientists from five research organizations have conducted the broadest field study of ocean acidification to date using sensors developed at Scripps Institution of Oceanography, UC San Diego. The study, "High-Frequency Dynamics of Ocean pH: A Multi-Ecosystem Comparison," is reported in today's issue of the journal PLoS One. It is an important step toward understanding how...

Observations at submarine springs found along the coast of Mexico's Yucatan Peninsula are giving scientists a preview of the possible fate of coral reef ecosystems in response to ocean acidification. The naturally low pH (a measure of acidity) in the water around the springs creates conditions similar to those that will result from the widespread acidification of surface waters that scientists expect to occur as the oceans absorb increasing amounts of carbon dioxide from the atmosphere....

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...

toccata
  • In music, a work for a keyboard-instrument, like the pianoforte or organ, originally intended to utilize and display varieties of touch: but the term has been extended so as to include many irregular works, similar to the prelude, the fantasia, and the improvisation.
This word is Italian in origin, coming from the feminine past participle of 'toccare,' to touch.
