North Pacific Ocean Upper Layer Temperature Profiles from CAYUSE Cruise

North Pacific Ocean data contains temperature-depth profiles from a mechanical bathythermograph (MBT) instrument deployed during the CAYUSE cruise from March 27 to 30, 1972. The dataset, processed by NODC into the C128 standard format, consists of pairs of temperature and depth values recorded at uniform 5-meter intervals down to a maximum depth of approximately 285 meters. It is hosted by NOAA NCEI and also appears on NASA EarthData, indicating cross-platform relevance.

Use Cases

• Analyzing the thermal structure of the upper ocean (0-285m) using temperature-depth pairs.
• Studying short-term temperature variability in a specific North Pacific region from cruise date and position data.
• Calibrating or validating ocean mixed-layer models with historical in-situ profile data.
• Investigating instrument characteristics and data standards of the Mechanical Bathythermograph (MBT) via the C128 format.

Strengths

• Data is processed to a known standard format (NODC C128), ensuring consistent structure.
• Provides specific instrument context with a maximum observation depth of approximately 285 meters.
• Covers a precise 4-day time range (1972-03-27 to 1972-03-30) from a single research cruise.
• Temperature values are recorded at uniform 5-meter depth intervals, facilitating systematic analysis.

Limitations

• Column names and exact row count are unknown from all provided sources.
• Data is limited to the upper ocean layers (<285m) due to instrument constraints.
• Sources conflict on the 'last updated' metadata (2026-03-05 on data.gov vs. 1972-03-30 on NASA EarthData).
