McLane Moored Profiler (MMP) measurements from moorings taken in the Eurasian and Makarov Basins, Arctic Ocean, 2021-2023

Eight long-term moorings were deployed in the Eurasian and Makarov Basins of the Arctic Ocean during the Nansen and Amundsen Basins Observational System (NABOS) 2021 cruise. Four of those moorings were equipped with McLane Moored Profiler (MMP) profilers. They were successfully recovered in September 2023. The primary goal of the mooring observations was to understand the role of stratification in controlling the transport of heat and other properties of Atlantic Water to the upper ocean and ice, specifically quantifying the structure and temporal variability of the main water masses, as well as obtaining detailed information about upper ocean, halocline, AW layer dynamics, and seasonal variations. This archive includes MMP measurements of temperature, salinity, and ocean velocities collected at MB1, MB5, MB6, and MB7 NABOS moorings in 2021-2023. The dataset contains MMP measurements and files with time stamps for each MMP profile.

在2021年南森与阿蒙森海盆观测系统（Nansen and Amundsen Basins Observational System, NABOS）航次期间，研究团队于北冰洋欧亚海盆与马卡罗夫海盆布放了8套长期锚系观测潜标。其中4套潜标搭载了麦克莱恩锚系剖面仪（McLane Moored Profiler, MMP）。所有潜标均于2023年9月成功回收。本次锚系观测的核心目标为阐明层结在调控大西洋水（Atlantic Water, AW）向上层海洋与海冰的输运及其他物理属性过程中发挥的作用，具体包括量化主要水团的结构与时间变异性，同时获取上层海洋、盐跃层、大西洋水层动力学特征及季节变化的精细化观测资料。本数据集存档了2021-2023年间，于NABOS项目MB1、MB5、MB6、MB7号锚系潜标处获取的麦克莱恩锚系剖面仪温度、盐度与海流观测数据。本数据集包含麦克莱恩锚系剖面仪观测数据，以及对应每条剖面的时间戳文件。
