Carbon Dioxide Emissions Keep Conch Snails From Escaping Predation
2014-01-07 13:18:57

Brett Smith for redOrbit.com - Your Universe Online New research from an international team of scientists has found that if more carbon dioxide makes its way into the ocean – conch snails will be more vulnerable to predation. Conch snails typically use a strong foot-like appendage to leap away from approaching predators. According to the team’s study, published in the Proceedings of the Royal Society B: Biological Sciences, when the snails are exposed to carbon dioxide levels...

Fluctuation 'adds insult to injury' for marine creatures A new Duke University-led study has documented dramatic, natural short-term increases in the acidity of a North Carolina estuary. "The natural short-term variability in acidity we observed over the course of one year exceeds 100-year global predictions for the ocean as a whole and may already be exerting added pressure on some of the estuary's organisms, particularly shelled organisms that are especially susceptible to changes in...

Rivers, Streams Release Far More Carbon Dioxide Than Do Lakes: Study
2013-12-10 06:51:50

April Flowers for redOrbit.com - Your Universe Online Contrary to common belief, rivers and streams release carbon dioxide (CO2) into the atmosphere at a rate five times greater than the world's lakes and reservoirs combined. The findings of this international study, which included the University of Waterloo, have been published in the journal Nature. "Identifying the sources and amounts of carbon dioxide released from continental water sources has been a gap in understanding the carbon...

Sea-Level Rise Will Continue To Fuel Destructive Coastal Flooding
2013-12-05 10:26:23

April Flowers for redOrbit.com - Your Universe Online Two new literature review studies, published in Nature, reveal changing coastal ocean functions. The first study, "Coastal flooding by tropical cyclones and sea-level rise," reveals that the clamor about whether climate change will cause increasingly destructive tropical storms may be overshadowing a more unrelenting threat to coastal property: sea-level rise. Jonathan D. Woodruff, an assistant professor of sedimentology and...

Anxiety In Fish Caused By Rising Ocean Acidification
2013-12-04 19:35:14

Scripps Institution of Oceanography, UC San Diego Study shows acidity levels projected by the end of the century results in behavioral changes that could impact feeding, fisheries A new research study combining marine physiology, neuroscience, pharmacology, and behavioral psychology has revealed a surprising outcome from increases of carbon dioxide uptake in the oceans: anxious fish. A growing base of scientific evidence has shown that the absorption of human-produced carbon dioxide...

Ocean Acidity Having Major Impact On Arctic Food Web Species
2013-12-03 06:27:12

April Flowers for redOrbit.com - Your Universe Online Tiny crustaceans, known as copepods, live just beneath the surface of the ocean. A research expedition to the Arctic, part of the Caitlin Arctic Survey, found that these tiny animals are more likely to battle for survival if ocean acidity continues to rise. The study, published in Proceedings of the National Academy of Sciences (PNAS), revealed that copepods that move large distances, migrating vertically across a wide range of pH...

New Generation Of Micro Sensors Developed For Monitoring Ocean Acidification
2013-11-13 14:14:45

National Oceanography Centre, Southampton (UK) The first step in developing a cost-effective micro sensor for long-term monitoring of ocean acidification has been achieved by a team of scientists and engineers. The new technology, that will measure pH levels in seawater, was developed by engineers from the National Oceanography Centre, in close collaboration with oceanographers from University of Southampton Ocean and Earth Science, which is based at the center. The team successfully...

Feast And Famine For Animals Living On The Abyssal Plain
2013-11-12 11:57:06

[ Watch The Video: Feast and Famine on the Abyssal Plain ] Monterey Bay Aquarium Research Institute Animals living on the abyssal plains, miles below the ocean surface, don’t usually get much to eat. Their main source of food is ”marine snow”—a slow drift of mucus, fecal pellets, and body parts—that sinks down from the surface waters. However, researchers have long been puzzled by the fact that, over the long term, the steady fall of marine snow cannot account for all the...

Toxic Ocean Conditions During Ancient Extinction Event Analyzed
2013-10-30 04:24:55

redOrbit Staff & Wire Reports - Your Universe Online Toxic oxygen-free and hydrogen sulfide-rich ocean conditions that existed during a major extinction event nearly 94 million years ago could repeat themselves in the future, according to new research being published online this week in the journal Proceedings of the National Academy of Sciences. Research, led by biogeochemists at the University of California, Riverside, suggests that the previous estimates of these oxygen-free,...

Receding Ice Exposes Seawater To Carbon Dioxide, Driving Ocean Acidification In The Arctic Ocean
2013-09-13 12:12:21

University of South Florida (USF Health) Acidification of the Arctic Ocean is occurring faster than projected according to new findings published in the journal PLoS One. The increase in rate is being blamed on rapidly melting sea ice, a process that may have important consequences for health of the Arctic ecosystem. Ocean acidification is the process by which pH levels of seawater decrease due to greater amounts of carbon dioxide being absorbed by the oceans 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...

call-note
  • The call or cry of a bird or other animal to its mate or its young.
'Call-note' is newer than 'bird-call,' which originally referred to 'an instrument for imitating the note of birds' but now also refers to 'the song or cry of a bird.'
