North Pacific Ocean Temperature Profiles from 1971 Cruise

285 meters is the maximum depth for temperature observations in this dataset, which captures the thermal structure of the upper ocean. The data consists of temperature-depth profile pairs recorded at uniform 5-meter intervals from the NOAA vessel CAYUSE. It was processed by the National Oceanographic Data Center (NODC) into the standard C128 format for mechanical bathythermograph (MBT) data.

Use Cases

• Analyzing the vertical temperature gradient in the upper ocean up to 285 meters depth.
• Studying short-term thermal variability over a three-day cruise period in June 1971.
• Correlating temperature profiles with specific cruise information, date, position, and time for each observation.
• Using standardized C128 format data for comparative studies with other historical bathythermograph records.

Strengths

• Data is processed to a known standard format (NODC C128) ensuring structural consistency.
• Provides precise temporal coverage for a specific three-day research cruise from June 12-14, 1971.
• Temperature measurements are recorded at a uniform 5-meter depth interval, facilitating analysis.

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, file size, and license information are unavailable across all sources.
• There is a conflict in freshness: one platform lists a 2026 update, while another shows the original 1971 date.
