YAQUINA Upper Ocean Temperature Profiles from 1971

North Pacific Ocean temperature-depth profiles collected from the YAQUINA vessel over three days in January 1971. The dataset contains processed mechanical bathythermograph (MBT) observations formatted to the NODC C128 standard. Data is limited to the upper 285 meters of the ocean, providing a snapshot of thermal structure.

Use Cases

• Analyzing thermal stratification by examining temperature values at uniform 5-meter depth intervals.
• Studying short-term upper ocean variability using cruise date, position, and time metadata for each profile.
• Calibrating or validating historical ocean models with precisely formatted NODC standard C128 data.
• Investigating regional conditions in the North Pacific using geographically and temporally bounded observations.

Strengths

• Data is processed to a consistent standard format (NODC C128) ensuring interoperability.
• Provides precise measurement intervals with temperature recorded at uniform 5-meter depth increments.
• Contains complete metadata for each observation, including cruise information, date, position, and time.

Limitations

• Row count, total size, and specific column names are not documented across any source.
• Observations are limited to a maximum depth of approximately 285 meters, excluding deeper ocean layers.
• Temporal coverage is very brief, spanning only three days in January 1971.
