North Pacific Upper Ocean Temperature Profiles from 1970

YAQUINA cruise data from the North Pacific Ocean provides temperature-depth profiles for the upper ocean layers. The dataset contains mechanical bathythermograph (MBT) observations processed into the NODC C128 standard format. Measurements were taken over two days in January 1970 by the National Oceanic and Atmospheric Administration.

Use Cases

• Analyzing the thermal structure of the upper ocean (up to ~285m) using temperature-depth value pairs.
• Studying short-term temperature variability over a two-day cruise period.
• Correlating ocean surface layer conditions with specific cruise dates, positions, and times.

Strengths

• Data is processed to a recognized standard format (NODC C128).
• Temperature measurements are recorded at uniform 5-meter depth intervals, enabling consistent profile analysis.
• Each observation includes associated metadata: cruise information, date, position, and time.

Limitations

• Row count, file size, and specific column names are unknown.
• The dataset is limited to the upper ocean, with a maximum observation depth of approximately 285 meters.
• Temporal coverage is extremely narrow, spanning only two days in 1970.
