Ocean Temperature Profiles from DIACHENKO Cruise in the North Pacific

5800017 is a dataset of mechanical bathythermograph (MBT) measurements collected during the DIACHENKO cruise in the North Pacific Ocean. It contains temperature-depth profile pairs recorded at uniform 5-meter intervals down to a maximum depth of approximately 285 meters. The data was processed by the National Oceanographic Data Center (NODC) into the standard C128 format.

Use Cases

• Analyzing the vertical temperature structure of the upper ocean (using temperature-depth value pairs).
• Studying historical ocean thermal conditions in the North Pacific (using cruise date, position, and time data).
• Validating or calibrating models of near-surface ocean heat content (using standardized C128 format profiles).

Strengths

• Data is standardized to the NODC C128 format, ensuring consistent structure.
• Temperature observations are recorded at a uniform 5-meter depth interval, facilitating analysis.
• Each profile includes associated metadata: cruise information, date, position, and time.

Limitations

• Key technical details like row count, file size, and specific column names are unavailable from all sources.
• The MBT instrument limits observations to a maximum depth of approximately 285 meters, restricting analysis to the upper ocean.
