The total hydrolysable amino acid(THAA),the ratios between D and L of amino acids(D/L) and the total organic carbon(TOC) were analyzed in surface sediments taken from the Eastern Lau Spreading Center(ELSC),South Pacific Ocean.The contents,sources and degree of decomposition of the organic matter(OM) in sediments have been investigated.The D/L ratios of amino acids were used to indicate the biological activity and temperature variation in hydrothermal field.The results showed that the contents of TOC and THAA in sediments were in the range of 0.70 – 2.15 mg/g(dry weight) and 30 – 511 μg/g(dry weight),respectively.The chemosynthetic-based in-suit community’s productivity in the hydrothermal systems contributed significant composition to the relative enrichment of THAA.The contents of THAA of the sediments were related to the in-suit community’s activity and composition,and the mineral composition of the sediments.The compositions of amino acids in sediments were different from each site for different hydrothermal system,because different hydrothermal system exhibits different hydrothermal activity,mineral composition of the sediments,and biological community.The percentage of organic carbon normalized to amino acid carbon(TAAC%) could be used to indicate the degree of degradation of sedimentary OM.The TAAC% showed that activity of OM in the hydrothermal vent fields was higher than those in non-hydrothermal vent fields.Relatively high temperature in the hydrothermal fields might influence the degradation path way of amino acids.The D/L ratios of aspartic acid(Asp),glutamic acid(Glu),serine(Ser) and alanine(Ala) in sediments showed a wide range,for example,the D/L ratios of Asp,Glu,Ser and Ala were 0.08 – 0.46,0.06 – 0.19,0.01 – 0.81 and 0.10 – 0.30,respectively.According to the contents of THAA,TAAC% and the D/L ratio of individual amino acid,the biological activity of biomass and the relative contribution of the THAA of bacteria could be assessed.However,it cannot be accurately distinguished between the hydrothermal active fields and non-hydrothermal active fields on the temperature and biological activities just by the composition of the amino acid.
