A robust and convenient method was developed to evaluate rates of microbial activity in gas-charged deepsea sediments at in situ hydrostatic pressure, temperature, and gas concentration. The method used a hydrostatic chamber to maintain high pressures of 50 bar and greater, and a modified Hungate tube and plunger to contain samples. This technique can be easily applied to quantifying rates of microbial processes sensitive to dissolved gas concentration (e.g., sulfate reduction, anaerobic… CONTINUE READING
