North Atlantic Ocean Temperature Profiles from 1965 MBT Survey

North Atlantic Ocean bathythermograph data collected by the vessel SEARCHER from April 21 to May 5, 1965. The dataset contains temperature-depth profiles processed by the National Oceanographic Data Center (NODC) into the standard C128 format, with observations limited to the upper 285 meters of the ocean. It provides a snapshot of the thermal structure for a specific cruise during this period.

Use Cases

• Analyzing historical temperature gradients in the upper ocean layer using paired temperature-depth values.
• Studying cruise-specific spatial and temporal thermal patterns with reported date, position, and time for each observation.
• Modeling or validating historical sea surface temperature and subsurface thermal data recorded at uniform 5-meter intervals.

Strengths

• Data is processed to a documented standard (NODC C128 format) ensuring consistent structure.
• Provides a focused temporal snapshot from a specific 15-day cruise in 1965.
• Recorded at uniform 5-meter depth intervals, facilitating systematic analysis.

Limitations

• Observations are limited to a maximum depth of approximately 285 meters, restricting analysis to the ocean's upper layer.
• Key metadata such as row count, file size, and specific column names are unavailable from the provided sources.
• Conflicting 'last updated' dates exist between platforms (2026-03-05 on datagov vs. 1965-05-05 on nasa_earthdata).
