Sentences with phrase «low aragonite»

Application of this model to time series data reiterates the direct association between low aragonite saturation state and upwelled waters and highlights the extent to which benthic communities on the Northern California shelf are already exposed to aragonite undersaturated waters.

Higher concentrations of chlorophyll in the areas of pronounced reef growth suggests that an abundance of food may provide the excess energy needed for calcification in waters with low aragonite saturation.

Not exact matches

Models suggest that if seawater becomes too low in aragonite, organisms with aragonite shells will dissolve.

Low levels of aragonite, an essential mineral in the formation of scleractinian skeletal structures, in the region make it difficult for the coral polyps to develop their rugged coral skeletons.

The graphic shows areas that are most vulnerable to ocean acidification since they are regions where the saturation of aragonite is lower.

Intriguingly, aragonitic CWC species are found close to and even below the aragonite saturation horizon (Roberts et al., 2009a; Findlay et al., 2014), raising the question of whether species adapted to lower saturation states may have inherent adaptations to future lower pH ocean conditions.

As the science develops, it is important for managers to design select examples of coral reef areas in a variety of ocean chemistry and oceanographic regimes (e.g., high and low pH and aragonite saturation state; areas with high and low variability of these parameters) for inclusion in MPAs.

These data link the Arctic Ocean's largest area of aragonite undersaturation to sea ice melt and atmospheric CO2 absorption in areas of low buffering capacity.

We highlight that the Arctic Ocean surface becomes undersaturated with respect to aragonite at even lower CO2 concentration (than the Southern Ocean).

«Southern Ocean acidification via anthropogenic CO2 uptake is expected to be detrimental to multiple calcifying plankton species by lowering the concentration of carbonate ion (CO32 − to levels where calcium carbonate (both aragonite and calcite) shells begin to dissolve.

This acidification occurs in a region with a naturally low carbonate ion concentration, and studies suggest that the surface of the Southern Ocean will become undersaturated with respect to calcium carbonate minerals aragonite and calcite by the end of the century.

At 100 %, waters are saturated (solid black line - the aragonite saturation horizon); values larger than 100 % indicate super-saturation; values lower than 100 % indicate undersaturation.

But since corals, be it with an aragonite or a calcite skeleton, both rely on symbiotic algae as their main source of energy they remain vulnerable, since those algae are highly susceptible to both low pH and high temperatures.
