Historical Ocean Temperature Profiles from the 1967 FURMAN Expedition

Mechanical bathythermograph data from the research vessel FURMAN, capturing temperature-depth profiles in the North Pacific Ocean. The dataset contains observations from a 26-day cruise in August and September 1967, processed into the NODC standard C128 format. It was collected and standardized by the National Oceanic and Atmospheric Administration.

Use Cases

• Analyzing the vertical temperature gradient of the upper ocean to a maximum depth of 285 meters.
• Studying short-term thermal variability in the North Pacific during late summer 1967.
• Correlating temperature observations with recorded cruise information, date, position, and time for each profile.
• Examining temperature data recorded at uniform 5-meter depth intervals for consistency.

Strengths

• Data is processed to a known standard format (NODC C128), ensuring structural consistency.
• Provides precise temporal coverage for a specific 26-day research cruise from 1967-08-13 to 1967-09 07.
• Records temperature at uniform 5-meter depth intervals, facilitating direct profile comparisons.

Limitations

• Key metadata such as row count, file size, and specific column names are unavailable from all sources.
• The mechanical bathythermograph instrument limits observations to approximately 285 meters, restricting analysis to the upper ocean.
• Sources conflict on the 'last updated' date, with one showing a future date (2026-04-01) and another the collection end date (1967-09-07).
