Mount Erebus Volcano Observatory: Operations, Science and Outreach (MEVO-OSO)

知识价值：埃里伯斯火山是世界上为数不多的火山之一，它有熔岩湖，可以很容易地观察到，几乎连续不断的斯特隆堡式爆炸活动。埃里伯斯也有一个独特的永久对流熔岩湖，由斜长石phonolite岩浆组成。多年来，在埃里伯斯火山山顶建立了重要的基础设施，作为埃里伯斯火山观测站（MEVO）的一部分，作为一个自然实验室，研究广泛的火山过程，特别是与一个开放的对流岩浆管道相关的岩浆脱气。PI建议将MEVO继续运营5年。基本的基础研究目标是：通过在冰洞中使用分布式温度传感和气体测量来了解扩散侧翼脱气，了解管道过程，并检查埃里伯斯火山排放对大气和冰冻圈环境的环境影响。为了检查管道过程，PI将通过视频记录、热成像、气体排放率和气体成分测量、地震和次声数据进行同步观测。更广泛的影响：埃里伯斯研究的一个重要方面是对学生的教育和培训。研究生和本科生都将有机会处理MEVO数据并部署到现场。此外，该提案将支持一名初中或高中科学教师进行两次实地考察。PI还将继续与各种媒体组织和电影人合作。

Intellectual Merit: Mt. Erebus is one of only a handful of volcanoes worldwide that have lava lakes with readily observable and nearly continuous Strombolian explosive activity. Erebus is also unique in having a permanent convecting lava lake of anorthoclase phonolite magma. Over the years significant infrastructure has been established at the summit of Mt. Erebus as part of the Mount Erebus Volcano Observatory (MEVO), which serves as a natural laboratory to study a wide range of volcanic processes, especially magma degassing associated with an open convecting magma conduit. The PI proposes to continue operating MEVO for a further five years. The fundamental fundamental research objectives are: to understand diffuse flank degassing by using distributed temperature sensing and gas measurements in ice caves, to understand conduit processes, and to examine the environmental impact of volcanic emissions from Erebus on atmospheric and cryospheric environments. To examine conduit processes the PI will make simultaneous observations with video records, thermal imaging, measurements of gas emission rates and gas compositions, seismic, and infrasound data.Broader impacts: An important aspect of Erebus research is the education and training of students. Both graduate and undergraduate students will have the opportunity to work on MEVO data and deploy to the field site. In addition, this proposal will support a middle or high school science teacher for two field seasons. The PI will also continue working with various media organizations and filmmakers.
