North Pacific Ocean Temperature Profiles from 1958 Cruise

5800005 is a dataset of mechanical bathythermograph (MBT) observations from the HANNA cruise in the North Pacific Ocean. The National Oceanic and Atmospheric Administration processed the data into the NODC C128 format, providing temperature-depth pairs recorded at uniform 5-meter intervals. It captures the thermal structure of the ocean's upper layers over a three-day period in February 1958.

Use Cases

• Analyzing the vertical temperature structure of the upper ocean (up to ~285m) for a specific location and time.
• Studying short-term thermal variability in the North Pacific Ocean using paired temperature-depth values.
• Validating or supplementing ocean model outputs for historical conditions using standardized cruise data.
• Investigating the capabilities and data characteristics of the historical Mechanical Bathythermograph (MBT) instrument.

Strengths

• Data is processed to a known, documented standard format (NODC C128).
• Temperature observations are recorded at a consistent, fine vertical resolution of 5-meter intervals.
• Each profile includes associated metadata such as cruise information, date, position, and time.

Limitations

• The dataset is limited to the upper ocean, with a maximum observation depth of approximately 285 meters.
• Key quantitative details like total row count, file size, and specific column names are unavailable from the provided sources.
• The temporal coverage is very brief, spanning only three days in February 1958.
