PERSEUS Cruise Historical Bathythermograph Data from 1964

NODC processed bathythermograph (MBT) data from the PERSEUS cruise in the Japan Sea and North Pacific Ocean. The dataset contains temperature-depth profile pairs recorded at uniform 5-meter intervals, useful for studying the thermal structure of the ocean's upper layers. Data collection occurred from June 7 to June 18, 1964.

Use Cases

• Analyzing upper ocean thermal structure using temperature-depth pairs.
• Studying historical temperature profiles at 5-meter depth intervals.
• Mapping cruise-based oceanographic observations with reported date, position, and time.
• Investigating temperature variability in the Japan Sea and North Pacific for a specific time period.

Strengths

• Data processed to a standard NODC format (C128) ensuring consistency.
• Provides a focused time series from a specific 12-day cruise in June 1964.
• Temperature values are recorded at uniform 5-meter depth intervals, facilitating analysis.

Limitations

• Maximum observation depth is approximately 285 meters, limiting analysis to the upper ocean.
• Column names, row counts, and exact data size are not specified in available metadata.
• Conflicting 'last updated' dates exist between platforms (2026 vs. 1964).
