TL;DR: In this article, the first discovery of gas hydrates exposed on the seafloor of the South China Sea was reported, and the in situ chemical compositions and cage structures of these hydates were measured at the depth of 1,130m below sea level using a Raman insertion probe (RiP-Gh) that was carried and controlled by a remotely operated vehicle (ROV) Faxian.

TL;DR: In this paper, an in situ Raman quantitative method for measuring dissolved CO2 suitable for a hydrothermal environment is established, and the Raman relative intensity of CO2 displayed a linear relationship with increasing CO2 under the investigated conditions.

TL;DR: In this paper, supercritical CO2 bubbles were identified as bubbles in hydrothermal vents in the south part of the Okinawa Trough using in situ Raman spectroscopy.

TL;DR: Based on the previously developed deep-sea hybrid Raman insertion probe for cold seeps, the in situ detection of a cold seep vent and geochemistry analysis of fluids in chemosynthetic communities were conducted at the Formosa Ridge in the northern South China Sea.

TL;DR: In this article, in situ Raman spectra of three SGH samples were acquired in order to determine the structure and the evolution of the synthetic gas hydrate, and the results indicated that the methane large-to-small cage occupancy ratios of the hydrates vary from 1.01 to 1.39.
