HiAOOS will develop, implement, and validate several ocean observing technologies to improve data collection in the ice-covered Arctic Ocean. A network of multipurpose moorings will be deployed for two years in the deep Nansen and Amundsen Basins. The network will provide point measurements of ocean and sea ice and active and passive acoustic data for several applications, including acoustic thermometry, geo-positioning of underwater floats, detection of marine mammals, geohazards and human generate noise. The mooring system will build on the successful basin wide Coordinated Arctic Acoustic Thermometry Experiment-CAATEX experiment and extend the existing Mooring Observationsfrom the Atlantic Water Inflow Experiment (ATWAIN). A new generation of moorings will be developed where data can be transferred to the surface using ROV or winch technology. Ice buoys with new acoustic array technology will be developed for testing of underwater geo-positioning, local navigation networks for glider operations and for localization of geophysical events. These developments will advance several research infra structures with new observing technology and create new opportunities for forefront research. To unlock the capabilities of the new observing system methods and tools will be developed to analyse and visualize the observations for different applications using digital methods and technologies including machine learning. The methods and tools will be ingested into a digital platform blue Insight, and available through Zenodo. Training and use cases will use the platform to train different user groups associated with research infrastructures, research communities and technology developers. All data, methods and tools will be available following the FAIR principles. Field experiments will be carried out every summer from 2024 to 2026, and every field experiment will be assessed with respect to environemntal impact prior to the start of the experiment.

HiAOOS将开发、实施和验证几种海洋观测技术，以改善冰雪覆盖的北冰洋的数据收集。将在南森和阿蒙森盆地深处部署一个多用途系泊系统，为期两年。该网络将提供海洋和海冰的点测量以及主动和被动声学数据，用于若干应用，包括声学测温、水下浮标的地理定位、海洋哺乳动物的探测、地质灾害和人类产生的噪音。系泊系统将建立在成功的全流域协调北极声学测温实验-CAATEX实验的基础上，并扩展了大西洋水流入实验（ATWAIN）的现有系泊观测。将开发新一代的系泊系统，使用绞车或绞盘技术将数据传输到水面。将开发采用新的声学阵列技术的冰浮标，用于测试水下地理定位、滑翔机作业的当地导航网络和地球物理事件的定位。这些发展将推动几个研究基础设施与新的观测技术，并创造新的机会，前沿研究。为了释放新观测系统的能力，将开发方法和工具，利用数字方法和技术，包括机器学习，为不同的应用分析和可视化观测结果。这些方法和工具将被纳入一个数字平台blue Insight，并通过Zenodo提供。培训和用例将使用该平台培训与研究基础设施、研究社区和技术开发人员相关的不同用户群体。所有数据、方法和工具都将遵循公平原则。从2024年到2026年，每年夏天都将进行实地实验，在实验开始之前，将对每次实地实验的生态影响进行评估。
