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.

这项研究是一个研究人员联盟巡游的时间至关重要的（快速）回应，以研究西太平洋中新发现的爆炸性爆发的海底火山（MATA）。积极爆发的海底火山的发现是一种稀有性和数据，该数据将收集许多基本地质，水热，火山和生物学问题。正在研究的火山目前正在爆发不寻常的组成熔岩，以表明弧形的初始阶段。因此，它们具有不寻常的化学性质，被认为与异国情调和极端成分的热液流体有关。与这些流体相关的新颖和以前未被发现的微生物生命形式的可能性是研究目标。将测量来自火山通风口的熔岩样品中的短寿命放射异位素，以获得喷发时间表。将检查与水热流体和爆发的熔岩样品，以阐明这种类型的岩浆作用在固体和流体相之间的挥发性和元素分配之间的关系。这项工作的更广泛影响包括研究生培训，对科学中性别不足的PI的支持，EPSCOR州立机构的PIS的支持以及公共宣传。还将在有关研究活动和结果的演讲方面向汤加人民展开展览。
