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.

2021年南森-阿蒙森海盆观测系统（Nansen and Amundsen Basins Observational System, NABOS）科考航次中，科研人员于北冰洋欧亚海盆与马卡罗夫海盆部署了8套长期潜标系统。其中4套潜标搭载了麦克莱恩潜标剖面仪（McLane Moored Profiler, MMP），所有潜标均于2023年9月顺利回收。本次潜标观测的核心目标为阐明层化作用在调控大西洋水（Atlantic Water, AW）向上层海洋与海冰的热输运及其他属性变化中的作用机制，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详细观测资料。本数据集存档了2021-2023年间，在MB1、MB5、MB6、MB7四套NABOS潜标上采集的MMP观测数据，涵盖温度、盐度与海洋流速三项参数。数据集包含MMP剖面观测数据，以及对应每条MMP剖面的时间戳文件。
