Sentences with phrase «changing seawater chemistry»

Recent near collapses of the oyster fishery in the Pacific Northwest, directly attributed to changing seawater chemistry, had substantial negative impacts on local jobs and economies.

Much of the research on ocean acidification to date has focused on the effect changing seawater chemistry has on the calcium carbonate shells of shellfish.

«The changing seawater chemistry means that those threads are going to get weaker.

Although the absorption of atmospheric CO2 by the ocean helps limit climate warming, it also changes seawater chemistry and causes ocean acidification.

«Ocean acidification can affect individual marine organisms along the Pacific coast, by changing the chemistry of the seawater,» said lead author Brittany Jellison, a Ph.D. student studying marine ecology at the UC Davis Bodega Marine Laboratory.

As atmospheric CO2 levels rise, those in the oceans do too, changing the chemistry of the seawater.

A set of chemical processes dissolves that CO2 and turns it into carbonic acid and sets off a complex changes to the chemistry of seawater, which dissolves shells and coral and creates a cascade effect that could disrupt entire marine ecosystems.

«The other carbon dioxide problem», «the evil twin of global warming», or part of a «deadly trio», together with increasing temperatures and loss of oxygen: Many names have been coined to describe the problem of ocean acidification — a change in the ocean chemistry that occurs when carbon dioxide (CO2) from the atmosphere dissolves in seawater.

Such priorities include: 1) establishing an ocean carbon chemistry baseline; 2) establishing ecological baselines; 3) determining species / habitat / community sensitivity to ocean acidification; 4) projecting changes in seawater carbonate chemistry; and 5) identifying potentially synergistic effects of multiple stressors.

As CO2 reacts with seawater, it generates dramatic changes in carbonate chemistry, including decreases in pH and in the concentration of carbonate ions.

Oceanic uptake of anthropogenic carbon dioxide (CO2) causes pronounced shifts in marine carbonate chemistry and a decrease in seawater pH. Increasing evidence indicates that these changes — summarized by the term ocean acidification (OA)-- can significantly affect marine food webs and biogeochemical cycles.

Anthropogenic CO2 emissions are leading to a gradual decrease in ocean pH and changes in seawater carbonate chemistry, a process known as ocean acidification (OA).

As CO2 reacts with seawater, it generates dramatic changes in carbonate chemistry, including decreases in pH and carbonate ions and an increase in bicarbonate ions.

The carbon dioxide buildup is changing the chemistry of surface seawater, lowering its pH in a way that, in theory, could be harmful to the shell - forming and reef - forming marine organisms of today's ocean ecosystem.

This process tends to buffer the chemistry of the seawater so that pH changes are lessened (see section 2.2.3 and Annex 1 for a more detailed review).»

This process tends to buffer the chemistry of the seawater so that pH changes are lessened» and «Essentially this is an area of great uncertainty.

It's been enough to raise the levels of the ocean — and the extra carbon in the atmosphere has also changed the chemistry of that seawater, making it more acidic and beginning to threaten the base of the marine food chain.

The ocean uptake of excess atmospheric carbon dioxide, the excess above preindustrial levels driven by human emissions, causes well - understood and substantial changes in seawater chemistry that can affect marine organisms and ecosystems.

Additional carbon dioxide uptake causes direct changes in seawater acid - base and inorganic carbon chemistry in a process termed ocean acidification.

Finding a way to reverse climate change is the foremost challenge of our time and the first step is collecting ocean data in order to help us understand how seawater chemistry is changing.

«Ocean acidification» (OA), a change in seawater chemistry driven by increased uptake of atmospheric CO2 by the oceans, has probably been the most - studied single topic in marine science in recent times.

Whether the decline we report can be attributed to single factors such as circulation changes that have not yet been documented, a fundamental difference in the cycling of carbon in this region, an alteration of carbon metabolism in these animals, perhaps via an effect of changing seawater carbon chemistry on shell composition (e.g. [8]-RRB-, or undescribed interactions among these factors is unknown.

The carbon dioxide emitted in addition to that which is produced naturally has changed the chemistry of seawater.

This change in seawater chemistry alters the way sound moves through the ocean, allowing it to propagate farther, particularly for sounds two and a half octaves above «middle C,» said researcher Keith Hester of the Monterey Bay Aquarium Research Institute in California.

The rapid uptake of heat energy and CO2 by the ocean results in a series of concomitant changes in seawater carbonate chemistry, including reductions in pH and carbonate saturation state, as well as increases in dissolved CO2 and bicarbonate ions [3]: a phenomenon defined as ocean acidification.
