YAQUINA Upper Ocean Temperature Profiles from 1970

North Pacific Ocean temperature-depth profiles collected by the YAQUINA vessel using a Mechanical Bathythermograph (MBT) from May 28 to June 9, 1970. Data was processed by the National Oceanographic Data Center (NODC) into the standard C128 format, containing pairs of temperature and depth values. The dataset is managed by the National Oceanic and Atmospheric Administration.

Use Cases

• Analyzing the thermal structure of the upper ocean (up to 285m) using temperature-depth pairs.
• Studying short-term temperature variability in the North Pacific Ocean during late spring 1970.
• Correlating temperature profiles with specific cruise information, date, position, and time for each observation.
• Benchmarking historical upper-ocean conditions against modern satellite or sensor data.

Strengths

• Data is processed to a known standard format (NODC C128), ensuring structural 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

• Row count, total size, and specific column names are not provided by any source.
• Instrument limitation: MBT maximum depth is approximately 285 meters, restricting analysis to the upper ocean only.
• Conflicting freshness: One platform lists a 2026 update, while another lists the data date (1970-06-09) as the last update.
