Mechanical Bathythermograph Data from Cayuse Cruise 1972

Temperature-depth profiles from the CAYUSE cruise in the North Pacific Ocean on May 22-23, 1972 comprise this dataset. Data was processed by the National Oceanographic Data Center (NODC) into the standard C128 format for Mechanical Bathythermograph (MBT) observations. It captures the thermal structure of the upper ocean to a maximum depth of approximately 285 meters.

Use Cases

• Analyzing historical temperature-depth profiles in the North Pacific upper ocean.
• Studying the thermal structure and layering of the ocean to a depth of 285 meters.
• Validating or supplementing ocean model outputs for the 1972 time period using cruise-based observations.
• Correlating temperature data with specific cruise information, date, position, and time for each cast.

Strengths

• Data is processed to a standardized NODC format (C128), ensuring consistent structure.
• Observations provide paired temperature-depth values at uniform 5-meter intervals.
• Dataset includes precise temporal coverage from a specific two-day cruise in May 1972.

Limitations

• Key quantitative details like row count, column names, and file size are unknown across all sources.
• Data is limited to the upper ocean, with a maximum observation depth of approximately 285 meters.
• Sources conflict on the last update date, with one showing 2026 and another showing 1972.
