Historical Upper Ocean Temperature Profiles from the STRONG Expedition

1954 to 1961 temperature-depth profiles from the STRONG expedition, collected via Mechanical Bathythermograph (MBT) in the Arabian Sea, Gulf of Aden, Gulf of Oman, North Atlantic Ocean, and Red Sea. The dataset contains processed observations useful for studying the thermal structure of the ocean's upper 285 meters. Data was standardized by the National Oceanographic Data Center (NODC) into the C128 format.

Use Cases

• Analyzing historical temperature gradients in the upper 285m of the ocean across multiple seas.
• Studying seasonal or interannual thermal variability from 1954-1961 using paired temperature-depth values.
• Mapping the spatial distribution of near-surface ocean temperatures using reported cruise, date, position, and time data.
• Calibrating or validating models of upper ocean heat content for the mid-20th century.

Strengths

• Provides a consistent 7+ year time series (1954-1961) for historical climate analysis.
• Data is processed to a standardized NODC format (C128), ensuring structural consistency.
• Covers multiple geographically distinct regions: Arabian Sea, Gulf of Aden, Gulf of Oman, North Atlantic, and Red Sea.

Limitations

• Instrument limitation: MBT maximum depth is ~285m, restricting analysis to the upper ocean only.
• Key metadata conflicts: row count, column names, and exact data size are unknown across all sources.
• Temporal freshness conflict: 'last_updated' dates differ significantly between platforms (1961 vs 2026).
