Non-Technical AbstractSeismology is the study of vibrations in the earth that result from earthquakes, volcanoes, and many other seismic sources. To better understand these vibrations, seismologists install highly sensitive equipment (seismometers) in carefully controlled environments to record the smallest possible signals providing higher quality data to analyze. Like listening to music on a bad set of speakers can remove the nuances of the particular song, seismometers in noisy installations cannot detect the nuances of say signals from a volcano. As these experiments move closer to the actual source (volcano) the environment gets more difficult to control, resulting in noisier data and less signal. Therefore, seismologists strive to improve the installations of seismometers in these difficult locations to improve the data recorded, and thus, improve the understanding of how, in this case a volcano, works and how better to understand the risks it poses. This project will seek to vastly improve seismometer installations in very extreme environments by developing a small, helicopter-portable drilling rig that can be flown to very high altitudes and be operated in very low temperatures. The target for the testing of this new drilling capability will be at the summit of Mt Erebus, Antarctica the southernmost active volcano on Earth and one that is less than 25 miles from the United States largest research base in Antarctica McMurdo Station. At the conclusion of this project, the researchers will have the capability to install high quality, posthole-style seismometers anywhere in the world in nearly any environment.Technical AbstractThis project consists of the development and proof-of-concept demonstration of new technology to install posthole-style seismic sensors in varied rock conditions at high altitude (above 3,000 m) and extremely cold locations, such as high volcanoes and/or mountain/polar regions. In particular, we propose to develop a helicopter-portable drilling system that can drill up to 15.25 cm cased and grouted, vertical postholes suitable for high-performance broadband seismic sensors or other instrumentation. A full demonstration of this capability is proposed by drilling five sites near the summit of Mt Erebus volcano and three sites around the perimeter of Ross Island, Antarctica to facilitate the installation of a new Erebus seismic and infrasound network. The capabilities developed under this award will be useful to geophysical and more general Earth science investigations in other areas and regions. The portability of the system combined with its ability to operate in extreme environments ensures that it will be more than suitable for operating in diverse conditions world-wide. This capability will enable collection of new types of and higher quality data, for scientific advancement. By engaging a broad and experienced team in the design phase, we expect to benefit from collective expertise and knowledge sharing and ensure that the designs and solutions we develop are effectively implemented in the final product that will broadly benefit the Earth science community.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

非技术抽象学是对地震，火山和许多其他地震来源产生的地球振动的研究。 为了更好地理解这些振动，地震学家在精心控制的环境中安装了高敏感的设备（地震米），以记录提供更高质量数据的最小信号。 就像在不好的扬声器上听音乐可以消除特定歌曲的细微差别一样，嘈杂装置中的地震仪无法检测到火山中的信号的细微差别。 随着这些实验越来越靠近实际来源（火山），环境变得更加难以控制，从而产生了噪声更大的数据和较少的信号。 因此，地震学家努力改善在这些困难位置的地震仪的安装，以改善记录的数据，从而提高人们对在这种情况下如何有效的理解以及如何更好地理解其带来的风险。该项目将通过开发一个可以将其飞行到非常高的高度飞行并在非常低温下操作的小型直升机式钻机来大大改善非常极端环境中的地震计安装。测试这种新钻孔能力的目标是在南极洲的Erebus Mt Erebus山顶上，是地球上最南端的活火山，距离美国最大的研究基地不到25英里。 在该项目的结论中，研究人员将有能力在几乎任何环境中在世界上任何地方安装高质量的后thole风格的地震仪。技术抽象的项目包括在高空（高于3,000 m/山上）和山区和山上和山上和山上，概念概念的概念概念概念示例以在各种岩石条件下安装postyle式地震传感器，例如高空/山上/山脉。特别是，我们建议开发一种可直升机便宜的钻井系统，该系统最多可钻高15.25厘米的套管和灌浆，垂直底座，适用于高性能宽带地震传感器或其他仪器。通过在埃雷布斯火山山顶附近的五个地点和南极罗斯岛周围的三个地点附近钻探五个地点，以促进安装新的Erebus地震和临界网络，这是通过在Erebus火山山顶和三个地点附近的五个地点进行钻探的完整演示。根据该奖项开发的能力将对其他领域和地区的地球物理和更一般的地球科学调查有用。系统的可移植性与其在极端环境中运行的能力相结合，可确保它将非常适合在全球各种条件下运行。该功能将使新型和更高质量数据的收集，以进行科学进步。通过在设计阶段与一支广泛而有经验的团队参与，我们希望从集体专业知识和知识共享中受益，并确保在最终产品中有效地实施了我们开发的设计和解决方案，这将广泛地使地球科学社区受益。该奖项反映了NSF的法定任务，并通过使用该基金会的知识优点和广泛的影响来评估NSF的法定任务，并被认为是值得的支持。
