Corals, shellfish, and other marine creatures made of calcium carbonate are
threatened by ocean acidification, a consequence of rising atmospheric carbon dioxide levels increasing dissolved CO2 in the ocean.
An «inherent bias» in scientific journals in favour of more calamitous predictions has excluded research showing that marine creatures are not
damaged by ocean acidification, which is caused by the sea absorbing carbon dioxide from the atmosphere.
New research, led by the University of Southampton, has questioned the role
played by ocean acidification, produced by the asteroid impact that killed the dinosaurs, in the extinction of ammonites and other planktonic calcifiers 66 million years ago.
Regarding the possible role hydrogen sulfide in the major extinctions you might want to check out another book, one which places it in the context of the methane clathrate gun, the destruction of the coccolithophores which help to maintain an oxygenated
atmosphere by ocean acidification, the role of algae blooms, etc...
Develop, test, and implement innovative interventions to reduce damage to reefs
weakened by ocean acidification, and to promote the replenishment of reef communities impoverished by loss of coral species to the combined impacts of climate change, including elevated seawater temperatures and sea - level rise.
Members of the German research network BIOACID (Biological Impacts of Ocean Acidification) are developing a model that links ecosystem changes
triggered by ocean acidification and climate change with their economic and societal consequences.
They studied harvests from shelled mollusks such as oysters, clams, and scallops because these fisheries are likely to be the first
harmed by ocean acidification in the United States.
Also predictable is that we can anticipate sea level rising by meters per century for centuries to come, and that the base of the ocean food chain will be drastically changed and probably
reduced by ocean acidification.
This study of course does not take away very different concerns related to stratospheric aerosol SRM geoengineering, like possible damage to the ozone layer [which in turn would be good news if you hate waiting for that spring tan] and the fact that allowing CO2 concentrations to keep rising presents other problems, like the necessity to never stop with the active process of SRM geoengineering, and increasing ecological damage
caused by ocean acidification.
This will increase the likelihood of protecting corals acclimated to a variety of pH conditions and spreads the risk of any coral species» survival being
compromised by ocean acidification.
Notably, in the face of the sustained, severe threat to marine life
posed by ocean acidification, the International Union for Conservation of Nature (IUCN), regards proposals to mitigate ocean acidification directly as a «threat» to biodiversity.
There is growing concern over the decline of fisheries and the overall health of the ocean: scientists estimate that 90 % of stocks are fished at or beyond sustainable limits, habitats like coral reefs are
threatened by ocean acidification, and large areas of ocean and coastlines are polluted.
Research suggests that the behavior of both predator and prey may be affected
by ocean acidification.
The tern feeds on plankton that may be affected
by ocean acidification.
«But this research has shown that fish such as barramundi — which only spend a short part of their lives in the ocean — will be impacted
by ocean acidification.»
But as soon as I started working here, I quickly became enthusiastic about how important they are for the whole ecosystem», says the marine biologist who is still eager to find out more about how exactly these tiny bacteria are affected
by ocean acidification and what this means for the coral reefs.
Crab, also, are affected
by ocean acidification.
If the organisms are unable to compensate for extra costs caused
by ocean acidification, by eating more, they suffer negative consequences in the form of reduced growth and fertility and in extreme cases death», Dr. Sam Dupont points out.
Shellfish are also being affected
by ocean acidification, much to the dismay of shellfish farmers.
Its left - coiled, high - spired shell is made of aragonite, a form of calcium carbonate that is easily affected
by ocean acidification.
Mollusks (including mussels and oysters) are dramatically affected
by ocean acidification and this could have an impact on aquaculture.
«So far it's completely unclear how these productivity hotspots are affected
by ocean acidification and what are the impacts on the oceanic food web.»
It's not clear to me whether David's worry is that it works very well and humanity ends up in this dependency that puts us in this ever - more - artificial world, in which all these things have been wiped out
by ocean acidification.
Here's a question... it seemed from my read of the Royal Society report that a significant number of plankton species might be adversely affected
by the ocean acidification.
Intrageneric variation in antipredator responses of coral reef fishes affected
by ocean acidification: implications for climate change projections on marine communities
