Historical North Pacific Upper Ocean Temperature Profiles from EAGLE

285 meters is the maximum observation depth for these mechanical bathythermograph (MBT) records. The dataset contains temperature-depth profile pairs from the USS EAGLE in the North Pacific Ocean, processed by the National Oceanographic Data Center (NODC) into its standard C128 format. Data collection occurred from April 1944 to September 1945, providing a snapshot of upper-ocean thermal conditions during World War II.

Use Cases

• Analyzing the thermal structure of the upper ocean (up to 285m) for a specific time period using temperature-depth pairs.
• Studying historical ocean conditions in the North Pacific region using cruise, date, position, and time metadata.
• Investigating seasonal temperature variations in the upper ocean layers from 1944 to 1945.
• Calibrating or validating models of historical ocean surface layer thermodynamics.

Strengths

• Data is processed to a known, documented standard (NODC C128 format).
• Temperature values are recorded at uniform 5-meter depth intervals, ensuring consistent vertical resolution.
• Covers a specific 17-month period (1944-04-01 to 1945-09-20) from a single vessel cruise.

Limitations

• Key structural metadata is missing: the exact number of rows, columns, and file size are unknown across all sources.
• Instrument limitation restricts observations to a maximum depth of approximately 285 meters, capturing only the upper ocean.
