North Pacific Ocean Temperature Profiles from J.R. Perry 1969

Bathythermograph (MBT) data from J. R. PERRY in the North Pacific Ocean from 1969-04-08 to 1969-04-30. The dataset contains temperature-depth profile pairs recorded at uniform 5-meter intervals, processed by the National Oceanographic Data Center (NODC) into its standard C128 format. It provides a focused record of upper ocean thermal structure for a single cruise in April 1969.

Use Cases

• Analyzing the vertical temperature gradient in the upper 285 meters of the North Pacific Ocean using the paired temperature-depth values.
• Studying short-term thermal variability during a specific cruise in April 1969 using the date, time, and position columns.
• Calibrating or validating historical ocean model outputs for the upper ocean using instrument-specific MBT data.

Strengths

• Data is processed to a known, documented standard (NODC C128 format) ensuring consistent structure.
• Temperature observations are recorded at a uniform 5-meter depth interval, facilitating systematic analysis.
• Provides precise cruise information, including date, position, and time for each profile observation.

Limitations

• The maximum observation depth is approximately 285 meters, limiting analysis to the ocean's upper layers only.
• Key metadata such as exact row count, file size, and license information is unavailable across all platforms.
• The dataset's temporal coverage is very narrow, spanning only 23 days in April 1969.
