North Pacific Ocean Temperature Profiles from CAYUSE Cruise

Temperature-depth profiles from the CAYUSE cruise in the North Pacific Ocean, collected using a Mechanical Bathythermograph (MBT) instrument. The dataset contains observations from August 19 to 28, 1969, processed into the NODC standard C128 format by the National Oceanographic Data Center. It is published by the National Oceanic and Atmospheric Administration.

Use Cases

• Analyzing the thermal structure of the upper 285 meters of the ocean using temperature-depth pairs.
• Studying short-term ocean temperature variability during a specific cruise in August 1969.
• Historical calibration or validation of oceanographic models for the North Pacific region.
• Research on upper ocean heat content and mixed-layer dynamics from point measurements.

Strengths

• Data is processed to a known, standard format (NODC C128) ensuring structured consistency.
• Temperature values are recorded at uniform 5-meter depth intervals, facilitating analysis.
• Each observation includes associated metadata: 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 metadata such as row count, column names, and exact file size are unavailable from the provided sources.
• There is a conflict in the 'last updated' date: one platform lists 2026-03-05, while another lists the original collection date of 1969-08-28.
