North Pacific Ocean Temperature Profiles from EVANS Cruise

Temperature-depth profiles from the EVANS cruise in the North Pacific Ocean, collected using a Mechanical Bathythermograph (MBT) instrument. The dataset contains processed observations formatted to the NODC C128 standard, with data recorded at uniform 5-meter intervals to a maximum depth of approximately 285 meters. Observations were made over a three-day period from January 24 to 26, 1967.

Use Cases

• Analyzing the vertical thermal structure of the upper ocean (using temperature-depth value pairs).
• Studying short-term ocean temperature variability in the North Pacific (using date, time, and position columns).
• Validating or calibrating ocean mixed-layer models (using high-resolution 5-meter interval profiles).
• Investigating historical oceanographic conditions from specific research cruises (using cruise information and location data).

Strengths

• Data is processed to a standardized format (NODC C128), ensuring consistency.
• Profiles have high vertical resolution with temperature recorded at uniform 5-meter depth intervals.
• Each observation includes associated metadata: cruise information, date, position, and time.

Limitations

• Instrument limits data to the upper ocean only, with a maximum observation depth of approximately 285 meters.
• Key metadata conflicts exist: row count, column names, size, license, and author are unknown or reported inconsistently across sources.
• Temporal coverage is very limited to a three-day cruise in 1967.
