Another important issue in the framework of the
project was the investigation of the microbially mediated methane turnover in the zones of methane accumulation within the sediment. Main cruise objectives:
 | | Hydro-acoustic mapping of subsurface gas plumes |
| | High-resolution bathymetric mapping and mapping of gas seeps by hydro-acoustic detection of gas flares in the water column |
| | Quantification of microbial turnover of gassy sediments and microbial mats |
| | Characterization of geochemical conditions for the anaerobic methane oxidation and its regional variation |
| | Characterization and identification of microorganisms involved in the anaerobic methane oxidation in the sediment and in microbial mats |

Working areas
Three working areas were chosen according to existing information on gas seeps distribution, accumulations of free gas in the sediment, and sediment geochemistry:1 - Danube Canyon
2 - North-western shelf
3 - Paleo-Dniepr area
