North Pacific Ocean Temperature Profiles from CAYUSE Cruise

North Pacific Ocean bathythermograph data was collected by the vessel CAYUSE on a single day in October 1969. The National Oceanographic Data Center processed the temperature-depth profile data into the standard C128 format, with measurements recorded at uniform 5-meter intervals down to a maximum depth of approximately 285 meters.

Use Cases

• Analyzing the vertical temperature gradient in the upper ocean using paired temperature-depth values.
• Studying historical sea surface and sub-surface thermal conditions for a specific location and date.
• Calibrating or validating ocean model outputs for the North Pacific region using in-situ profile data.

Strengths

• Data is processed to a documented standard format (NODC C128).
• Temperature measurements are recorded at a consistent, high-resolution 5-meter depth interval.
• Cruise metadata including date, position, and time is reported for each observation.

Limitations

• The dataset is limited to a single day of observations, providing a very narrow temporal snapshot.
• The maximum observation depth of ~285 meters restricts analysis to the ocean's upper layer only.
• Conflicting metadata exists for the last update date (1969 vs. 2026), casting doubt on provenance clarity.
