North Atlantic Ocean Temperature Profiles from 1965

Bathythermograph data records temperature-depth pairs from the research vessel SEARCHER in the North Atlantic Ocean. The dataset contains profiles from a 20-day cruise in January 1965, processed by the National Oceanographic Data Center (NODC) into the standard C128 format. It captures the thermal structure of the ocean's upper layers to a maximum depth of approximately 285 meters.

Use Cases

• Analyzing the vertical temperature structure of the upper ocean at 5-meter intervals.
• Studying short-term thermal variability in the North Atlantic during January 1965.
• Correlating temperature profiles with specific cruise dates, times, and geographic positions.
• Providing a historical baseline for comparisons with modern ocean temperature data.

Strengths

• Data is processed to a known, documented standard format (NODC C128).
• Provides precise temporal coverage for a specific 20-day cruise from 1965-01-07 to 1965-01-27.
• Records data at uniform 5-meter depth intervals, enabling consistent profile analysis.

Limitations

• Key structural metadata like row count, column names, and file size are unavailable across all sources.
• Instrument limitation restricts observations to a maximum depth of ~285m, excluding deeper ocean layers.
• Conflicting 'last updated' dates between platforms (2026 vs 1965) create uncertainty about metadata maintenance.
