South Pacific Upper Ocean Temperature Profiles from 1970

Bathythermograph (MBT) data from UNANUE in the South Pacific Ocean from 1970-09-01 to 1970-09-21. The dataset contains temperature-depth profile pairs recorded at uniform 5-meter intervals down to approximately 285 meters, processed by the National Oceanographic Data Center (NODC) into its standard C128 format. Cruise information, date, position, and time are reported for each observation.

Use Cases

• Analyzing the thermal structure of the upper ocean (0-285m) using temperature-depth pairs.
• Studying spatial and temporal variability of sea surface temperature and mixed layer depth from cruise-based profiles.
• Validating or providing historical context for ocean model simulations in the South Pacific region.
• Researching oceanographic conditions from a specific research vessel (UNANUE) during September 1970.

Strengths

• Data is processed to a known, documented standard (NODC C128 format).
• Temperature measurements are recorded at a consistent, high-resolution interval (5 meters).
• Each observation includes associated metadata: cruise, date, position, and time.

Limitations

• Key technical specifications are unknown: total row count, file size, and complete column list.
• The dataset's license and author are not specified across the provided sources.
• Data is limited to the upper ocean, with a maximum observation depth of approximately 285 meters.
