This research will improve our knowledge on how underwater volcanoes erupt, how their products are transported under water, and what type of deposits are generated on the sea floor. The IODP Expedition 350 will drill/core hundreds of metres of volcaniclastic sediments in a submerged portion of the Izu-Bonin arc (south of Japan), where sediment accumulated over millions of years, giving an unprecedented record of submarine volcanism and evolution of the arc. Facies analysis of volcanic textures, detailed stratigraphy, and clast chemistry will be used in this project. This study will help determining whether the deposits where partly erupted subaerially, and whether they are linked to direct input from submarine eruptions, or if they are result of re-sedimentation of previous deposits. Such information is necessary for worldwide hazard assessment to vessels and coastal populations, and for a better understanding of submarine volcanoes in general.

这项研究将提高我们对水下火山如何爆发，其产物如何在水下运输以及海底产生何种沉积物的认识。IODP 350号考察队将在伊豆-小笠原弧（日本南部）的水下部分钻取数百米的火山沉积物/取芯，那里的沉积物积累了数百万年，提供了前所未有的海底火山活动和弧演化记录。本项目将使用火山结构相分析、详细地层学和碎屑化学。这项研究将有助于确定沉积物是否部分在水下喷发，以及它们是否与海底喷发的直接输入有关，或者它们是否是以前沉积物重新沉积的结果。这些资料对于在全世界范围内对船只和沿海居民进行危险评估以及更好地了解海底火山的一般情况都是必要的。
