YAQUINA Bathythermograph Upper Ocean Temperature Profiles

285 meters is the maximum observation depth for these mechanical bathythermograph (MBT) records. The dataset contains temperature-depth profile pairs from the YAQUINA cruise in the North Pacific Ocean, processed by the National Oceanographic Data Center (NODC) into its standard C128 format. Data collection occurred over a three-day period in November 1969.

Use Cases

• Analyzing temperature variation with depth at 5-meter intervals up to 285m.
• Studying short-term thermal conditions in a specific North Pacific region.
• Correlating cruise information, date, position, and time with observed temperature profiles.
• Providing a historical baseline for upper ocean heat content studies.

Strengths

• Data is processed to a documented standard format (NODC C128).
• Temperature values are recorded at uniform 5-meter depth intervals, enabling consistent analysis.
• Includes precise temporal coverage from 1969-11-02 to 1969-11-04.

Limitations

• Key metadata such as row count, column names, and file size are unavailable from all sources.
• The dataset is limited to the upper ocean, with a maximum observation depth of approximately 285 meters.
• Sources conflict on the last updated date, reporting either 1969-11-04 or 2026-03 05.
