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