North Pacific Ocean Temperature Profiles from 1965 Cruise

NOAA_NCEI provides bathythermograph (MBT) data collected during cruise T 441 in the North Pacific Ocean from September 13 to 16, 1965. The dataset contains temperature-depth profile pairs recorded at uniform 5-meter intervals down to a maximum depth of approximately 285 meters. It has been processed into the NODC standard C128 format for mechanical bathythermograph observations.

Use Cases

• Analyzing the vertical thermal structure of the upper ocean using paired temperature and depth columns.
• Studying short-term ocean temperature variability during a specific cruise period in September 1965.
• Calibrating or validating ocean model outputs for the North Pacific region using historical in-situ measurements.
• Investigating cruise-specific oceanographic conditions by linking temperature profiles with reported date, position, and time metadata.

Strengths

• Data is processed to a recognized standard format (NODC C128), ensuring consistency.
• Provides detailed metadata for each observation, including cruise information, date, position, and time.
• Temperature measurements are recorded at a uniform, high-resolution interval of 5 meters.

Limitations

• Key quantitative details like total row count, file size, and complete column list are unknown.
• The MBT instrument's maximum depth of ~285m limits analysis to the ocean's upper thermal layers only.
• Conflicting last updated dates exist between sources (2026-03-05 on datagov vs. 1965-09-16 on nasa_earthdata).
