Historical Ocean Temperature Profiles from the Mikhail Lomonosov

Temperature-depth profiles from the upper ocean layers collected by the research vessel Mikhail Lomonosov. The data, processed to the NODC C128 standard, covers a 14-month cruise in the North and South Atlantic Oceans. Each observation includes cruise metadata, position, and time, with temperature recorded at uniform 5-meter intervals.

Use Cases

• Analyzing thermal stratification in the upper 285 meters of the Atlantic Ocean using temperature-depth pairs.
• Studying seasonal or spatial temperature changes across the North and South Atlantic from 1963 to 1964.
• Validating or supplementing historical ocean model reanalyses with in-situ profile data.
• Correlating surface ocean conditions with cruise metadata like date, position, and time.

Strengths

• Data is standardized to the NODC C128 format, ensuring consistent structure for profile analysis.
• Provides a focused 14-month time series (1963-03-16 to 1964-05-17) from a single research vessel.
• Temperature measurements are recorded at uniform 5-meter depth intervals, facilitating direct comparison.

Limitations

• Maximum observation depth is approximately 285 meters, limiting analysis to the ocean's upper layers only.
• Key metadata like row count, column names, and license are not provided across all sources.
• The last update date conflicts between platforms (2026-03-05 on datagov vs. 1964-05-17 on nasa_earthdata).
