High resolution boron isotopic compositions of a coral from the northern South China Sea and their implications for reconstruction of seawater pH. KE TING, WEI GANGJIAN, LIU YING, et al, 2015. Chinese Science Bulletin, 51(10): 1228-1237 (in Chinese with English abstract). Discovery of seep carbonate nodules as new evidence for gas venting on the northern continental slope of South China Sea. Key words: deep-water corals, hydrocarbon seepage, C-O isotope, bottom current, northern South China Sea This discovery is important for the studies on environmental effects of deep-water currents and of cold springs in the region. This research discovered cold-water corals in a cold seep region of the northern South China Sea. The δ 13C and δ 18O results were close to the carbon and oxygen isotopic values of cold-water corals in other parts of the world, but were quite different from those of warm-water corals, cold-seep carbonate rocks and low-temperature hydrothermal carbonate rocks. Stable carbon and oxygen isotopic analyses revealed that the δ 13C and δ 18O of cold-water corals were -7.36‰ ~ -1.15‰ and -1.38‰ ~ 3.67‰, respectively.

We identified two species ( Crispatotrochus sp.1, Crispatotrochus sp.2) and four genera. In this study, we investigated cold-water corals retrieved from the cold seep area in the northern South China Sea. Cold-water corals, also known as deep-water corals, are newly found ecological resources with high biological diversity and attract scientific research on environmental changes.
