Scientists Pinpoint How Ocean Acidification Weakens Coral Skeletons（图）
Scientists Ocean Acidification Weakens Coral Skeletons
2018/2/1
The rising acidity of the oceans threatens coral reefs by making it harder for corals to build their skeletons. A new study details how ocean acidification affects coral skeletons, enabling scientists...
Following the highly publicized 1998 E1 Niño event, interest in how climatic events in the tropics affects global climate has grown. However, an understanding of the long-term natural variability...
Na/Ca variability in coral skeletons
coral skeleton Na/Ca ratio Mg/Ca ratio Sr/Ca ratio S/Ca ratio marine aragonite
2017/8/9
In aragonitic coral skeletons, the Na/Ca molar ratio is clearly higher than any other minor- or trace-element/Ca molar ratio (i.e., Na/Ca > Sr/Ca ≥ S/Ca ≥ F/Ca ≈ Mg/Ca). However, little attention has ...
High sensitivity measurements of nitrogen isotopic ratios in coral skeletons from Palau, western Pacific: Temporal resolution and seasonal variation of nitrogen sources
coral skeleton δ15N value δ18O value δ13C value seasonal variation
2017/8/10
By using a step-wise heating method in conjunction with static vacuum mass spectrometry, we have measured at high temporal resolution (one month) the nitrogen isotopic ratio of a coral skeletal sample...
Heterogeneity of coral skeletons isotopic compositions during the 1998 bleaching event

2014/5/4
The vulnerability of coral reefs to climate change, such as regional warming, became fully evident during the strong 1997-1998 El Nino event. This El Nino episode was associated with elevated sea-surf...
Multiple scattering on coral skeletons enhances light absorption by symbiotic algae
Multiple scattering coral skeletons enhances light absorption symbiotic algae
2014/5/9
The success of symbiotic reef-building corals is largely determined by the efficiency with which they collect solar energy. Using thin coral laminae from the Caribbean scleractinian Porites branneri, ...
