Abstract
As part of the demonstration mission in the framework of the EC ESONET (European Seas Observatory NETwork) project, the multi-parametric seafloor observatory SN-4 was deployed at a key site along the North Anatolian Fault in the Gulf of Izmit, where low-intensity gas seepages were observed.

Purpose
The deployment the SN4 submarine observatory along the North Anatolian Fault track in the Izmit Gulf was projected in order to collect a 1-year data series of seismicity an fluid emission from the seafloor and study possible correlations between seismicity and gas methane emission in an active seismic zone.
