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

该INSPIRE奖部分由地球科学理事会极地计划司的北极自然科学计划，工程理事会电气，通信和网络系统司的通信，电路和传感系统计划以及计算机和信息科学与工程理事会的计算机和网络系统司资助。PI建议设计和开发一个集成的水下声学传感器网络，用于冰覆盖的海洋。它将通过声波将数据从地下海洋传感器无线传输到与卫星和互联网连接的地面接收阵列。在海冰从1）平滑的陆地坚冰到2）脊状移动的冰再到3）开放水域的过渡区，PI将扩大水下通信网络的限制和能力。这个过渡区在拟议的网络化传感器和通信网络阵列的30 - 50公里范围内在时间和空间上都在演变。 这一目标需要整合来自一系列不同学科的现有知识和每个学科内的智力创新。它将修改水下通信网络理论，沿海声传播和散射，以及海洋学的实验设计。为了提供长期、远距离的声学连接，PI团队将应对三大新的研究挑战：1）过渡区中的中频（1 - 5 kHz）、中程（10 km）声波传播; 2）新通信环境中的数据遥测; 3）应对和利用过渡区复杂动态的弹性传感器网络。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，以支持格陵兰图勒的海洋实验。传感器和通信网络将支持1）长期，智能分布式北极观测系统，2）遥感和原位冰下测量的同化，3）区域和全球气候模拟与实时测量。这样一个网络有望彻底改变极地冰下海洋采样。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加因努皮亚特Qaanaaq村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.
