Rates of sulfate reduction (SR) and anaerobic oxidation of methane (AOM) in hydrothermal deep-sea sediments from Guaymas Basin were measured at temperatures of 5 to 200 degrees C and pressures of 1 x 10(5), 2.2 x 10(7), and 4.5 x 10(7) Pa. A maximum SR of several micromoles per cubic centimeter per day was found at between 60 and 95 degrees C and 2.2 x 10(7) and 4.5 x 10(7) Pa. Maximal AOM was observed at 35 to 90 degrees C but generally accounted for less than 5% of SR.
在瓜伊马斯海盆热液深海沉积物中,于5至200摄氏度的温度以及1×10⁵、2.2×10⁷和4.5×10⁷帕的压力下,测量了硫酸盐还原(SR)速率和甲烷厌氧氧化(AOM)速率。在60至95摄氏度以及2.2×10⁷和4.5×10⁷帕的条件下,发现最大硫酸盐还原速率为每天每立方厘米几微摩尔。在35至90摄氏度观察到最大甲烷厌氧氧化速率,但通常占硫酸盐还原速率不到5%。
