Exploration of the Submarine Deposits and Morphology of Santorini Volcano, Greece

在这笔资金下，PI建议使用侧扫声纳、单通道气枪地震仪、火花线和水下探测器对圣托里尼火山的海底特征进行地球物理和摄影调查。目的是完善火山周围的地震地层学，并将其与沉积过程联系起来，确定圣托里尼岛侧翼和邻近盆地目前的沉积和侵蚀过程，寻找海底破火山口的矿藏形成，试图确定米诺斯海岸线和公元前1628年火山爆发和破火山口坍塌之前该岛的形态，对Kolumbo海底火山的火山产物进行取样，研究Kolumbo的生长过程。这项工作将作为罗得岛大学的Robert Ballard博士计划在克里特岛和圣托里尼岛之间地区进行的为期7天的调查航行的补充。该研究涉及一些重要的更广泛的影响，包括教育（虽然研究生的时间是有限的），火山灾害，国际合作，与巴拉德的杰森计划的参与，等等。

Under this funding, the PIs propose to carry out geophysical and photographic surveys of the submarine features of Santorini volcano using side-scan sonar, single channel air-gun seismics, sparker lines, and an ROV. The objectives will be to refine the seismic stratigraphy around the volcano and relate it to sedimentary processes, identify current depositional and erosional processes on the flank of Santorini and adjacent basins, search for the formation of mineral deposits in the submarine caldera, attempt to identify the Minoan coast line and configuration of the island prior to the 1628 BC eruption and caldera collapse, sample volcanic products of Kolumbo submarine volcano and examine the growth processes of Kolumbo. The work will be conducted as a 7-day add-on to a survey cruise already planned in the area between Crete and Santorini by Dr. Robert Ballard of the University of Rhode Island. The study involves a number of important broader impacts including education (although graduate student time is limited), volcanic hazards, international cooperation, involvement with the Jason Program of Ballard, and others.
