The PIs will deploy an autonomous underwater hydrophone (AUH) network in conjunction with OBSs in the Lau Basin. Since T-wave generation processes are not well understood the PIs will use the AUH and the OBSs to compare and establish how to integrate the datasets, allowing them to constrain the tectonics of the region and monitor both earthquake activity and volcanism. The comparison will allow future hydrophone data to be used to extract quantitative information regarding earthquake source parameters and processes. Broader impacts include collecting both the seismically-generated signals and whale songs which will be used in the proposed development of a K-12 curriculum module that includes the building of a hydrophone. There is also graduate and undergraduate student participation and continued public outreach by the PIs at local, national, and international levels.

这些专业人员将在Lau盆地部署一个自主水下水听器（AUH）网络，并与OBS一起部署。由于T波生成过程尚未得到很好的理解，PI将使用AUH和OBS来比较和确定如何整合数据集，使他们能够约束该地区的构造并监测地震活动和火山活动。比较将允许未来的水听器数据被用来提取有关震源参数和过程的定量信息。更广泛的影响包括收集地震产生的信号和鲸鱼的歌声，这些信号和歌声将用于拟议的K-12课程模块的开发，其中包括建造一个水听器。也有研究生和本科生的参与，并继续由PI在地方，国家和国际层面的公共宣传。
