McLane Moored Profiler (MMP) measurements from moorings taken in the Eurasian and Makarov Basins, Arctic Ocean, 2023-2025

Nine long-term moorings were deployed in the Eurasian and Makarov Basins of the Arctic Ocean during the Nansen and Amundsen Basins Observational System (NABOS) 2023 cruise. Four of those moorings were equipped with McLane Moored Profiler (MMP) profilers. They were successfully recovered in September 2025. 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 (AW) 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 McLane Moored Profiler (MMP) measurements of temperature, salinity, and ocean velocities collected at MB1, MB5, MB6, and MB7 NABOS moorings in 2023-2025. The dataset contains McLane Moored Profiler (MMP) measurements and files with time stamps for each MMP profile.
