Abstract: As a molecular fingerprint technique, Raman spectroscopy has been widely used in the qualitative 
 identification and quantitative analysis for the targets, and it has also been gradually applied 
 to the in situ detection of deep-sea extreme environment in past decades. The development of the 
 laser Raman spectroscopy for deep ocean  in situ detection is reviewed. The kinds of deep ocean 
 Raman spectrometers developed by now are introduced, and the applications of the spectrometers 
 for in situ detection of the seepage fluids, the sediment pore water, the carbonate minerals, 
 and the  hydrate are also presented. Finally, the factors that limit the broader application 
 of the Raman spectroscopy in the deep ocean are summarized and discussed, which provides a 
 reference for the future development of Raman spectroscopy.

Key words: Raman spectroscopy, cold seep, hydrothermal vent; in situ detection
