An Areal Assessment of Subseafloor Carbon Cycling in Cold Seeps and Hydrate-Bearing Areas in the Northern South China Sea

Figure 2

Spatial distribution of rates of organoclastic sulfate reduction (OSR), anaerobic oxidation of methane (AOM), methanogenesis (ME), and authigenic carbonate precipitation (CP) in the three areas. The black dots represent spatial distribution of sampling sites. Different colors denote different ranges of biogeochemical rates. In comparison to the interpolation rates of OSR, ME, and AOM in Dongsha, a smaller area was confined in the interpolation rate of CP. Additionally, rates of OSR, ME, AOM, and CP have the same interpolation region and so do those in Xisha.
