Pearl Harbor Bathythermograph Temperature Profiles 1946

NOAA_NCEI provides bathythermograph (MBT) data collected in the North Pacific Ocean near Pearl Harbor between April 25 and June 14, 1946. The dataset contains temperature-depth profile pairs recorded at uniform 5-meter intervals down to a maximum depth of approximately 285 meters. Data 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 paired temperature-depth values.
• Studying historical sea surface temperature variability near Pearl Harbor during the specified time period.
• Calibrating or validating ocean model outputs for the North Pacific region using in-situ profile data.
• Investigating cruise-specific oceanographic conditions using reported cruise information, date, position, and time.

Strengths

• Data is processed to a known standard format (NODC C128), ensuring consistency.
• Provides a specific and complete time range of observations from 1946-04-25 to 1946-06-14.
• Contains detailed metadata per observation including cruise information, date, position, and time.

Limitations

• Key metadata conflicts exist: row count, column names, and exact file size are unknown across all sources.
• The MBT instrument's maximum depth of ~285m limits analysis to the upper ocean only.
• The dataset is historical and covers a very short, specific time period.
