YAQUINA Ship Upper Ocean Temperature Profiles from 1970

North Pacific Ocean temperature-depth profiles collected by the YAQUINA vessel using Mechanical Bathythermograph (MBT) instruments. The dataset covers a two-week period from June 16 to June 29, 1970, and was processed and standardized into the NODC C128 format by the National Oceanographic Data Center. It contains pairs of temperature and depth values recorded at uniform 5-meter intervals down to a maximum depth of approximately 285 meters.

Use Cases

• Analyzing the vertical thermal structure of the upper North Pacific Ocean using temperature-depth pairs.
• Studying short-term oceanic temperature variability during June 1970 using time-stamped cruise observations.
• Correlating sea surface and subsurface temperature patterns with recorded date, position, and time data.
• Benchmarking historical ocean thermal conditions against modern measurements from the same region.

Strengths

• Data is processed to a known standard format (NODC C128), ensuring consistent structure.
• Temperature measurements are recorded at a uniform high-resolution interval of 5 meters.
• Provides precise temporal coverage for a focused two-week observational period in June 1970.
• Cross-platform presence on datagov and nasa_earthdata signals its archival importance.

Limitations

• Key metadata such as row count, file size, column names, and license are unreported across all sources.
• Instrument limitation: MBT observations are restricted to a maximum depth of ~285m, capturing only the upper ocean layer.
• No direct conflicts between sources were noted, but the absence of concrete data volume details is a limitation.
