| Numerous methane-emitting bottom features, such as seeps, methane clathrate hydrates (clathrates), and mud volcanoes, have been identified recently in the Black Sea. The fluxes of methane from these sources averaged over large spatial scales are unknown. Here we take advantage of the fact that the Black Sea is a semi-enclosed basin with restricted deep water circulation to establish first-order estimates of basin-wide fluxes of methane from these sources to the water column and atmosphere. First, we measured tile natural radiocarbon content of methane (C-14-CH4) dissolved in the water column and emitted from seeps. The C-14-CH4 results showed that the dominant source of methane to the water column is emitted from seeps and a smaller source is... |
