Historical North Pacific Ocean Temperature-Depth Profiles

North Pacific Ocean bathythermograph (MBT) data from the JASPER project, covering the period from August 1943 to June 1947. 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 by the National Oceanographic Data Center (NODC) into the standard C128 format.

Use Cases

• Analyzing the thermal structure of the upper ocean layers using temperature-depth value pairs.
• Studying historical ocean conditions in the North Pacific region via cruise information, date, position, and time metadata.
• Investigating seasonal or interannual variability in near-surface ocean temperatures from 1943 to 1947.

Strengths

• Data is processed to a recognized standard format (NODC C128).
• Provides a multi-year time series from 1943 to 1947 for historical analysis.
• Contains detailed metadata per observation, including cruise information, date, position, and time.

Limitations

• The maximum observation depth is approximately 285 meters, limiting analysis to upper ocean layers.
• Key quantitative details like row count, file size, and specific column names are unknown.
• Conflicting 'last updated' dates exist between platforms (2026-03-05 on datagov vs. 1947-06-13 on nasa_earthdata).
