项目摘要
In April 2006, extraordinary observations of a deep-sea explosive (Strombolian) volcanic eruption were made at NW Rota-1, a submarine volcano in the Mariana arc of the western Pacific. This research funds a return to the volcano to collect observational and analytical data and its subsequent on-shore data analysis and interpretation. Instruments including hydrophones, chemical sensors, current meters, and plume sensing devices will be deployed at the eruption site for one year. During the cruises, visual observations will made. A time-series collection of lava, gas and fluids at the active volcanic vent will also take place. Vent fluids and biological specimens from local hydrothermal vent sites will also be sampled. In terms of scientific impact, the research provides an opportunity to learn about volcanological process that have been impossible to study directly until now. Owing to the high viscosity of water, compared to air, closer and more specific observation and sampling of a Strombolian eruption can take place at Rota 1 than can be accomplished in subaerial settings. As a result, this work reveals critical proceses that help unravel eruptive mechanism of a highly destructive type of explosive volcanism. Broader impacts include public outreach via the media. The work also involves inter-Agency participation, an interdisciplinary inter-institutional collaboration, and the training a graduate student.
2006年4月,在西太平洋马里亚纳弧的一座海底火山--西北罗塔-1火山,对深海(斯特龙博利亚)火山喷发进行了非凡的观测。这项研究为返回火山收集观测和分析数据以及随后的陆上数据分析和解释提供了资金。包括水听器、化学传感器、海流计和羽流传感装置在内的仪器将在喷发地点部署一年。在巡航期间,将进行目测观察。活动火山喷口的熔岩、气体和流体的时间序列收集也将发生。来自当地热液喷口的喷口流体和生物标本也将被采样。在科学影响方面,这项研究提供了一个了解火山过程的机会,到目前为止,这些过程一直不可能直接研究。由于水的高粘度,与空气相比,在罗塔1可以对斯特龙博利亚喷发进行更近距离和更具体的观察和采样,而不是在空中环境中完成。因此,这项工作揭示了有助于揭开高度破坏性类型火山喷发机制的关键过程。更广泛的影响包括通过媒体进行公众宣传。这项工作还包括机构间参与、跨学科机构间协作和研究生培训。
