INSPIRE Track 1: Acoustic Sensor Networks for Ice-Covered Seas

该INSPIRE奖的部分资金来自地球科学局极地项目部的北极自然科学项目，工程局电气、通信和网络系统部的通信、电路和传感系统项目，以及计算机和信息科学与工程局的计算机和网络系统部门。项目建议设计和开发一个用于冰雪覆盖海域的综合水声传感器网络。它将通过声波将水下海洋传感器的数据无线传输到与卫星和互联网表面连接的接收阵列。这些pi将扩大过渡区水下通信网络的限制和能力，在过渡区，海冰从1)光滑的陆地固定冰转变为2)脊状流动冰，3)开放水域。这个过渡区在30-50公里的网络传感器和通信网络阵列的足迹范围内，在时间和空间上都在发展。这一目标需要整合来自不同学科的现有知识和每个学科内的智力创新。它将对水下通信网络理论、海岸声传播与散射、海洋学实验设计等方面产生重大影响。为了提供长期、远程的声学连接，PI团队将解决三个主要的新研究挑战：1)中频（1-5 kHz），中频（10公里）声波在过渡区传播；2)新通信环境下的数据遥测；3)弹性传感器网络，应对和利用复杂的动态过渡区。多学科团队将实现可靠的调制解调器硬件，将其与弹性网络协议集成，并优化北极部署的系统设计，以支持格陵兰岛图勒附近的海洋实验。传感器和通信网络将支持1)长期、智能的分布式北极观测系统，2)遥感和原位冰下测量的同化，以及3)实时测量的区域和全球气候建模。这样的网络有望彻底改变极地地区冰下海洋的采样。数据将通过网络广泛传播，并存档供公众查阅。计划中的外联活动包括参与来自卡纳亚克因纽特村的格陵兰居民的实地方案，以及从小学到社区大学的有意义的课堂参与。pi还致力于通过其全球印刷、广播、电视和电子媒体的联系进行外联。

This INSPIRE award is partially funded by the Arctic Natural Sciences Program in the Division of Polar Programs in the Directorate for Geosciences, the Communications, Circuits and Sensing Systems Program in the Division of Electrical, Communications and Cyber Systems in the Directorate for Engineering,and the Division of Computer and network Systems in the Directorate for Computer and Information Science and Engineering. The PIs propose to design and develop an integrated underwater acoustic sensor network for ice-coveredseas. It will transmit data wirelessly through acoustic waves from sub-surface ocean sensors to a receiving array with a surface connection to satellites and the Internet. The PIs will expand the limits and capabilities of underwater communication networks in the transition zone where sea ice changes from 1) smooth land-fast ice to 2) ridged mobile ice to 3) open water. This transition zone evolves in both time and space within the 30-50 km foot-print of the proposed networked sensor and communication network array. This goal requires integration of both existing knowledge from a set of diverse disciplines and intellectual innovations within each discipline. It will modify underwater communication network theory, coastal acoustic propagation and scattering, and experimental design of oceanography. Providing long-term, long-range acoustic connectivity, the PI team will address three major new research challenges: 1) Mid-frequency (1-5 kHz), mid-range (10 km) acoustic wave propagation in the transition zone; 2) Data telemetry in the new communication environment; and 3) Resilient sensor networks that cope with and harness complex dynamics of the transition zone. The multi-disciplinary team will implement reliable modem hardware, integrate it with resilient network protocol, and optimize the system design for Arctic deployment to support an ocean experiment off Thule, Greenland.The sensor and communication network will support 1) long-term, intelligent distributed Arctic observing systems, 2) assimilation of remote-sensing and in-situ under-ice measurements, and 3) regional and global climate modeling with real-time measurements. Such a network holds the promise to revolutionize under-ice ocean sampling in polar regions. Data will be broadly disseminated via the web and archived for public access. Planned outreach includes participation in the field program of Greenlandic residents from the Inupiat village of Qaanaaq and meaningful classroom involvement from the elementary to community college levels. The PIs are also committed to outreach through their global print, radio, TV, and electronic media contacts.
