This research is a time critical (RAPID) response cruise by a coalition of investigators to examine a newly discovered explosively erupting undersea volcano (Mata) in the Western Pacific Ocean. The discovery of actively erupting undersea volcanoes is a rarity and data that addresses many fundamental geological, hydrothermal, volcanic, and biological issues will be collected. The volcano being investigated is presently erupting unusual lavas of compositions indicative of the initial stages of arc formation. As such they have an unusual chemistry and are thought to be associated with hydrothermal fluids of exotic and extreme compositions. The likelihood that novel and previously undiscovered microbiological life forms associated with these fluids is a study target. Short lived radiogenic isotopes in lava samples from the volcanic vent will be measured to obtain an eruptive timeline. Coexisting hydrothermal fluids and erupted lava samples will be examined to elucidate the relationship between volatile and element partitioning between solid and fluid phases during this type of magmatism. Broader impacts of the work include graduate student training, support of a PI whose gender is under-represented in the sciences, support of PIs from an institution in an EPSCoR state, and public outreach. Outreach to the Tongan people in terms of presentations on research activities and results will also be carried out.

这项研究是由调查人员联盟进行的一次时间关键(快速)巡航，目的是检查西太平洋新发现的一座爆炸性海底火山(MATA)。海底火山活跃喷发的发现是罕见的，将收集许多基本的地质、热液、火山和生物问题的数据。正在调查的火山目前正在喷发不寻常的熔岩，其成分表明了弧形形成的初始阶段。因此，它们具有不同寻常的化学成分，并被认为与稀有和极端成分的热液流体有关。与这些流体相关的新的和以前未发现的微生物生命形式的可能性是一个研究目标。将测量来自火山口的熔岩样品中的短期放射性同位素，以获得喷发的时间表。将研究共存的热液流体和喷发的熔岩样品，以阐明在这类岩浆作用期间挥发分和元素在固体和液体相之间的分配关系。这项工作的更广泛影响包括研究生培训、支持在科学中性别比例不足的PI、支持EPSCoR州机构的PI以及公众宣传。还将向汤加人民介绍研究活动和成果。
