HiAOOS - High Arctic Ocean Observation System

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。一个多用途系泊网络将在Nansen和Amundsen盆地部署两年。该网络将为几种应用提供海洋和海冰的点测量以及主动和被动声学数据，包括声学测温、水下浮子的地理定位、海洋哺乳动物探测、地质灾害和人类产生的噪声。该系泊系统将建立在成功的全盆地协调北极声学测温实验- caatex实验的基础上，并扩展现有的大西洋水流入实验（ATWAIN）系泊观测。新一代的系泊系统将被开发出来，其中数据可以通过ROV或绞车技术传输到地面。将开发具有新声学阵列技术的冰浮标，用于测试水下地理定位、滑翔机操作的本地导航网络和地球物理事件的定位。这些发展将利用新的观测技术推进若干研究基础设施，并为前沿研究创造新的机会。为了解锁新观测系统的功能，将开发方法和工具，使用包括机器学习在内的数字方法和技术来分析和可视化不同应用的观测结果。这些方法和工具将被纳入一个数字平台蓝色洞察，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组。所有数据、方法和工具将遵循公平原则提供。2024 - 2026年每年夏季进行野外试验，并在试验开始前进行环境影响评估。

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.
