Sentences with phrase «of acidification»

There doesn't seem to be a lot of scientific literature on the effect of acidification on marine ecosystems.
It is probably premature to make definitive claims about the effects of acidification on individual examples without further research.
They were caused by changes to the ocean's chemistry brought about by absorption of two primary greenhouse gases, carbon dioxide and methane, through a process of acidification of ocean water.
The impact of this acidification can already be observed today and could have ramifications for the biological feedbacks in the future.
Most marine organisms can't adapt quickly enough to the rising rate of acidification.
If large scale changes in the ocean ecology occur because of acidification the model can not reasonably be expected to capture the effects.
A pioneering technique that involves the use of satellite - mounted thermal cameras and microwave sensors allows scientists to identify parts of the ocean that are most at risk of acidification.
Previous episodes of acidification — possibly caused by CO2 released from huge, sustained volcanic eruptions — had a tremendous ecological impact.
It is possible that the corals in question are species that are more tolerant of acidification.
When both factors were combined, the positive temperature effect compensated for the negative effect of acidification — regardless of how much food the animals received.
Five cultures each were kept under control conditions (15 °C) and at elevated water temperature (26 °C) in combination with three different concentrations of carbon dioxide (CO2): a control value with today's conditions, the conditions of the Intergovernmental Panel on Climate Change's «worst case scenario» and the highest possible degree of acidification.
Writing in Science, the researchers predict that with increasing levels of acidification, most coral reefs will be gradually dissolving away by the end of the century.
Currently, scientists rely on ships, buoys, floats and lab tests to track the data and although these disparate pieces can construct a baseline of acidification, there are gaps in coverage.
So far, the evidence is mixed for the role of acidification, Menge admits.
Cost - effective Control of Acidification and Ground - Level Ozone.
If the high amount of acidification seen in the Atlantic Ocean had been caused by atmospheric CO2 alone, that would suggest a huge amount of CO2 had to go into the atmosphere to cause 5 °C warming.
Alcamo, J., R. Shaw, and L. Hordijk, 1990: The RAINS model of acidification: Science and Strategies in Europe, Kluwer Academic Publishers, Dordrecht, The Netherlands.
There are opposite latitudinal gradients in these threats to reefs, meaning that areas projected to experience annual bleaching later are exposed to the effects of acidification for longer.
Using direct measurements and computer models, oceanographer Scott Doney of Woods Hole Oceanographic Institution and his colleagues calculated that acid rain causes as much as 50 percent of the acidification of coastal waters, where the pH can be as low as 7.6.
In fact, we found the inhibition of acidification of endosomes enhances the effect of conventional chemotherapy in mice, «says Dr. Lluís Espinosa.
Stealthily, the oceans have begun the process that scientists call commitment, the unstoppable inevitability of acidification that presages destruction long before it is clearly visible.
Orly Levitan, an author of what may have been the first study of acidification boosting nitrogen fixation, says she would consider changing her seawater recipe based on the new paper if she were to revisit this work.
Less clear are the impacts of acidification stress and multiple stressors on deep - sea fish populations and fisheries production (Rosa and Seibel, 2008).
«A study of coral reefs in the vicinity of carbon dioxide sources in Papua New Guinea suggests that there are indeed both winners and losers of acidification.
Daily dosages vary with diet and the amount of acidification need.
Effects of acidification on olfactory - mediated behaviour in freshwater and marine ecosystems: a synthesis
Regarding your discussion of acidification of the oceans, that line of reasoning is somewhat stretched, because you are looking at the change in pH of the surface layer, which overtime mixes with the subsurface layer.
A combination of acidification and global warming could be turning oceans toxic and threatens to destabilise the balance of marine life, say US marine scientists.
That explains why there is no acidification from acid rain in the ocean, but plenty of acidification in the Northern granite enclosed lakes.
Clearly, a first priority will be drastically reducing GHG emissions to slow the onset of acidification; a more comprehensive set of laws aimed at curbing overfishing, pollution and resource extraction (amongst other human activities) will need to be implemented in a way to ensure that local and regional authorities are sufficiently empowered to act.
: — A cooler world is better in absorbing Co2 — Absorbing more CO2 means a slowing of acidification of the seas — Methane hydrates and other methane sources become increasingly unstable in a warmer world, which could result in catastrophic warming if a huge amount of destabilized methane hydrates would be released into the atmosphere (which seems to have happened in the past)
Recent investigations suggest that at the present rate of acidification of the Southern Ocean, pteropods (marine pelagic molluscs) will not be able to survive after 2100 and their loss will have significant consequences for the marine food web (Orr et al., 2005).
For the study, five cultures were kept under a constant temperature and three different concentrations of carbon dioxide (CO2): a control value with today's conditions, the conditions that could be reached until the end of this century according to the most critical calculations of the Intergovernmental Panel on Climate Change (IPCC), and the highest possible degree of acidification.
We focused on echinoplutei to gain an understanding of where sensitivities of larval growth and calcification lie, with regard to particular levels of acidification / pCO2 and carbonate mineral saturation.
