Using high-resolution acoustic backscatter intensity as a proxy for sediment thickness provides a viable tool to estimate relative age of ridge axis lavas in regions of high glacial and post-glacial sedimentation rates.<u></u><u></u></p><p class="m_-7401417654234423857MsoPlainText"><u></u> <u></u></p><p class="m_-7401417654234423857MsoPlainText">I will present preliminary results from the POS502 research cruise to the N-Kolbeinsey Ridge this summer. The main goal of the cruise was to map in detail the morphological variations of seafloor lava flows and their effect on hydro-acoustic properties using a high resolution photographs using a DeepSurveyCam System mounted on the ROV. Individual lava flows were also sampled in order to determine their age and for geochemical analyses.<u></u><u></u></p><p class="MsoNormal"><span style="color:#1f497d"><u></u> <u></u></span></p><p class="MsoNormal"><span style="color:#1f497d"><u></u> <u></u></span></p><p class="MsoNormal"> <u></u><u></u></p><p class="MsoNormal">Best,<u></u><u></u></p><p class="MsoNormal"><u></u> <u></u></p><p class="MsoNormal">Maren & Maria<u></u><u></u></p><p class="MsoNormal"><u></u> <u></u></p><p class="MsoNormal"><u></u> <u></u></p><p class="MsoNormal"><u></u> <u></u></p><p class="MsoNormal" style="margin-bottom:12.0pt"><span style="font-size:12.0pt;font-family:"Times New Roman",serif"><u></u> <u></u></span></p><p class="MsoNormal" align="center" style="text-align:center"><span style="font-size:12.0pt;font-family:"Times New Roman",serif"><u></u> <u></u></span></p><p class="MsoNormal"><span style="font-size:12.0pt;font-family:"Times New Roman",serif"><u></u> <u></u></span></p><p class="MsoNormal" style="margin-bottom:12.0pt"><span style="font-size:12.0pt;font-family:"Times New Roman",serif"><u></u> <u></u></span></p><div class="MsoNormal" align="center" style="text-align:center"><span style="font-size:12.0pt;font-family:"Times New Roman",serif"><hr size="1" width="99%" noshade style="color:#909090" align="center"></span></div><p class="MsoNormal"><span style="font-size:12.0pt;font-family:"Times New Roman",serif"><u></u> <u></u></span></p></div>
