| Purpose | |
| Abstract | The main objectives of cruise leg M76/3b were the comparative biological, geological and biogeochemical analyses of fluid and gas seepage at cold seep ecosystems of the West African continental margin. This includes the detailed mapping of gas and fluid venting as well as gas hydrates and their associated ecosystems. Though multibeam data was recorded, it was not the main focus of the cruise and no further information have been provided by the responsible party. |
