The Acoustic Wave Glider manufactured by Liquid Robotics, is a mobile, unmanned, quiet, ocean surface vehicle for the study of marine soundscapes and detection of acoustically tagged marine animals. The glider is powered by batteries recharged by solar photovoltaic panels and propelled by wave action, so that long unmanned missions can be achieved at very low cost. The glider can travel along programmed transects for months-long deployments collecting meteorological and ocean data and recording and identifying species that make sounds in the ocean soundscape, including both the natural (geophony and biophony) and anthropogenic (anthropophony) sounds. Some of the species that can be studied with the acoustic sensors on this glider include the endangered Atlantic sturgeon, red drum, striped bass, groupers, bluefin tuna, sharks, endangered right whales and bottlenose dolphins. The instrument package on the glider will allow multiple and simultaneous measurements of the ocean environment (waves using a Datawell MOSE-G1000 wave sensor; currents using a Teledyne RDI Acoustic Doppler Current Profiler; temperature, salinity, depth and dissolved oxygen using a Sea-Bird CTD+DO sensor; and turbidity and phytoplankton abundance using a Turner C-3 pumped fluorometer) and near-surface weather (air temperature, rainfall, wind speed using an Airmar 200WX Weather Station) during missions. An acoustic tag receiver (Vemco VR2C sensor) will be used to detect and track acoustically tagged animals, and a recording hydrophone and analysis system (Decimus PAMBuoy sensor) will record sounds produced by marine animals and classify them. The glider will be used to monitor areas for the presence of sound-producing animals, to avoid noise and other impacts to threatened species in shipping and transportation corridors, to identify and protect fishing areas, and to assess impacts to areas proposed for wave and wind energy development, sand mining areas, and oil and gas leases. Data reports will be relayed from all the glider sensors to land-based computers via satellite and mobile phone modems in near-real-time for analysis, mapping and archival. Our overarching objective with the Acoustic Wave Glider is to document ocean habitats and biologic communities in continental shelf and slope waters to determine static communities (e.g., reefs) and migratory pathways of highly mobile species (e.g., fishes, marine mammals, sea turtles). Secondary objectives include providing data to oceanographers on environmental conditions during normal conditions and storm events to enhance storm prediction models. Storms and rainfall events can be analyzed for their impacts on ocean communities through acoustic analysis of organism responses. Storm events often cannot be sampled by vessels due to danger to life and equipment, but wave gliders are specifically designed to survive and report ambient ocean conditions, even during storm sea states and hurricanes. The glider will be featured at public displays of research at the NC aquariums, including static displays and interactive touch screens of glider tracks are planned. Scientific forums, seminars, and other public events will be scheduled, and glider users will be encouraged to write public interest articles about mission results for news media and magazines. The results of studies based data collected with the glider will be presented at scientific meetings and published in peer-reviewed journals.

液体机器人公司制造的声波滑翔机是一种移动的无人驾驶的安静的海洋表面车辆，用于研究海洋音景和探测声学标记的海洋动物。 滑翔机由太阳能光伏电池板充电的电池提供动力，并由波浪作用推动，因此可以以非常低的成本实现长期无人驾驶任务。滑翔机可以沿着编程的断面进行为期数月的部署，收集气象和海洋数据，记录和识别在海洋声景中发出声音的物种，包括自然（生物音和生物音）和人为（人工音）的声音。 一些物种，可以研究与声学传感器在这个滑翔机包括濒危大西洋鲟鱼，红鼓，条纹鲈鱼，石斑鱼，蓝鳍金枪鱼，鲨鱼，濒危露脊鲸和海豚。滑翔机上的仪器包将允许对海洋环境进行多次和同时的测量（波浪使用Datawell MOSE-G1000波浪传感器;海流使用Teledyne RDI声学多普勒海流剖面仪;温度、盐度、深度和溶解氧使用Sea-Bird CTD+DO传感器;和浊度和浮游植物丰度使用特纳C-3泵荧光计）和近地表天气（使用Airmar 200 WX气象站测量的气温、降雨量、风速）。 一个声学标签接收器（Vemco VR 2C传感器）将用于探测和跟踪有声学标签的动物，一个记录水听器和分析系统（Decimus PAMBuoy传感器）将记录海洋动物发出的声音并对其进行分类。 该滑翔机将用于监测发声动物存在的区域，避免噪音和对航运和运输走廊中受威胁物种的其他影响，识别和保护捕鱼区，并评估对拟议波浪和风能开发区域的影响、砂矿区以及石油和天然气租赁。 数据报告将通过卫星和移动的电话调制解调器从所有的滑翔机传感器传送到地面计算机，以进行近实时的分析、绘图和存档。 声波滑翔机的首要目标是记录大陆架和斜坡沃茨的海洋栖息地和生物群落，以确定静态群落（例如，珊瑚礁）和高度移动的物种的迁移路径（例如，鱼类、海洋哺乳动物、海龟）。 次要目标包括向海洋学家提供关于正常情况和风暴事件期间环境状况的数据，以加强风暴预测模型。风暴和降雨事件可以通过生物响应的声学分析来分析其对海洋群落的影响。由于对生命和设备的危险，风暴事件通常不能由船只进行采样，但波浪滑翔机是专门设计用于生存和报告环境海洋条件的，即使在风暴海况和飓风期间。滑翔机将在NC水族馆的公共研究展示会上展出，包括静态展示和滑翔机轨道的交互式触摸屏。 科学论坛、研讨会和其他公共活动将被安排，滑翔机用户将被鼓励为新闻媒体和杂志撰写关于使命结果的公共利益文章。基于滑翔机收集的数据的研究结果将在科学会议上提出，并发表在同行评审的期刊上。
