North Atlantic Upper Ocean Temperature Profiles from 1965

1965-08-13 to 1965-08-30 temperature-depth profiles from the North Atlantic Ocean, collected via mechanical bathythermograph (MBT) aboard the J. R. PERRY. The dataset, processed by the National Oceanographic Data Center (NODC) into standard C128 format, contains pairs of temperature and depth values recorded at uniform 5-meter intervals. It captures the thermal structure of the ocean's upper layers to a maximum depth of approximately 285 meters.

Use Cases

• Analyzing the vertical thermal structure of the upper North Atlantic Ocean for a specific cruise in August 1965.
• Correlating temperature observations at uniform 5-meter depth intervals with spatial position and time data.
• Studying historical ocean surface layer heat content and mixed layer depth using instrument-limited MBT data.
• Using cruise information, date, position, and time metadata to reconstruct specific observational contexts.

Strengths

• Provides a focused temporal snapshot from a specific 18-day cruise in August 1965.
• Data is structured in a standardized NODC C128 format with consistent 5-meter depth intervals.
• Includes essential metadata for each observation: cruise, date, position, and time.

Limitations

• Instrument maximum depth of ~285m limits analysis to the upper ocean thermal structure only.
• No column names, row counts, or file size information is provided by the sources.
• Sources disagree on the last updated date (2026-04-01 on Data.gov vs. 1965-08 30 on NASA Earthdata).
