©2020 Biological and Chemical Oceanography Data Management Office.This time course experiment was performed to test if the uptake rate of 3H-CH4 is linear over the chosen incubation time (3 days) for the seawater samples.
Methodology:
Sampling and analytical procedures:
Methane concentrations were measured by headspace equilibration method, modified from Kinnaman et al., 2007.
Fractional methane turnover rates were analyzed based on the 3H-labeled methane incubation protocol by Bussmann et al., 2015.
Methane oxidation rates were calculated assuming adherence to the first-order rate law, by multiplying fractional methane turnover rate and ambient methane concentration (Valentine et al., 2001).
Samples were collected from R/V Connell.
