Methods used for the survey include high resolution&amp;nbsp;subbottom seismic profiles (29.4 line kilometers; EdgetechCHIRP system at frequencies 2&lt;sup&gt;-16&lt;/sup&gt;&amp;nbsp;kHz) side-scan sonar backscatter surveys of the seafloor (approximately 67 line-km, Starfish&amp;nbsp;450F), single-beam bathymetry (approx. 67 line-km, Lowrance LCX-15MT Sonar system),&amp;nbsp;and bottom sampling including bottom sediment grab samples (van veen grab sampler) and&amp;nbsp;short sediment cores. The survey was focused at both ends of Argostoli Bay (i.e., Argostoli&amp;nbsp;and Livadi inlets). Preliminary analysis of the sub-bottom profiles in the upper 12-20 m reveals&amp;nbsp;a clear pattern of sediment layers, in both ends of the bay. The uppermost layers been&amp;nbsp;deposited horizontally with small differences in their orientation in the area of Argostoli inlet,&lt;/div&gt;
&lt;div&gt;while the presence of gas is more pronounced in Livadi inlet. Moreover, in Argostoli inlet a&amp;nbsp;palaeo-surface is visible (probably the base of Holocene sedimentary cover) with minor&amp;nbsp;channel features, likely indicating a shallow river valley. Side- scan mapping in combination&amp;nbsp;with sediment samples and cores showed that the surface sediment consists mostly of finegained&amp;nbsp;material, rich in organic matter over a gravel-lag deposit that may represent the&amp;nbsp;transgressive surface in the area.&lt;/div&gt;</style></abstract></record></records></xml>
