Skeletal mineralogy of coral recruits under high temperature and pCO2
Aragonite, which is the polymorph of CaCO3 precipitated by modern corals during skeletal formation, has a higher solubility than the more stable polymorph calcite. This higher solubility may leave animals that produce aragonitic skeletons more vulnerable to anthropogenic ocean acidification. It is therefore important to determine whether scleractinian corals have the plasticity to adapt and pro...
متن کاملBenthic marine calcifiers coexist with CaCO3-undersaturated seawater worldwide
Ocean acidification and decreasing seawater saturation state with respect to calcium carbonate (CaCO3) minerals have raised concerns about the consequences to marine organisms that build CaCO3 structures. A large proportion of benthic marine calcifiers incorporate Mg into their skeletons (Mg-calcite), which, in general, reduces mineral stability. The relative vulnerability of some marine calcif...
متن کاملCoralline algae in a naturally acidified ecosystem persist by maintaining control of skeletal mineralogy and size
To understand the effects of ocean acidification (OA) on marine calcifiers, the trade-offs among different sublethal responses within individual species and the emergent effects of these trade-offs must be determined in an ecosystem setting. Crustose coralline algae (CCA) provide a model to test the ecological consequences of such sublethal effects as they are important in ecosystem functioning...
متن کاملInteractive comment on “Skeletal mineralogy of coral recruits under high temperature and pCO2” by T. Foster and P. L. Clode
General comments. This study presents a good overview of the CaCO3 polimorph precipitation in corals skeletal formation, investigating the ability of corals to switch from aragonite to calcite precipitation, especially in their early developmental stages in response to changing seawater chemistry. Mg/Ca ratio, temperature and pCO2 has been already recognized as the most important factor affecti...
متن کاملRole of Mineralogy and Geochemistry in the Beneficiation of Jajarm Bauxite from North East Iran: Comparison with some other Bauxite Deposits of the World
Two types of bauxite occur in the Jajarm Bauxite deposit, the first one is the hard bauxite and the other is the shaly bauxite or soft bauxite. The Al 2 O 3 content ranges from 30% to 60% and SiO 2 varies between 5% to 39%.The total tonnage is more than 22 million tons with a mean value of Al 2 O 3 content between 47% to 48% , SiO 2 around 10% and Fe 2 O 3 ranges between 6.95 to 27% . The Jajar...
