Ocean Temperature Profiles from the RV Norwalk in 1965

Temperature-depth profile data from the research vessel Norwalk in the North Atlantic Ocean, collected using a Mechanical Bathythermograph (MBT) instrument. The dataset covers a cruise period from March 26 to April 30, 1965, and has been processed by the National Oceanographic Data Center (NODC) into its standard C128 format. It provides paired temperature-depth values recorded at uniform 5-meter intervals down to a maximum depth of approximately 285 meters.

Use Cases

• Analyzing the vertical thermal structure of the upper ocean using temperature-depth pairs.
• Studying historical oceanographic conditions during a specific North Atlantic cruise in spring 1965.
• Calibrating or validating ocean models with in-situ temperature profile data.
• Investigating short-term temperature variability using time-stamped observations from a fixed vessel track.

Strengths

• Data is standardized to the NODC C128 format, ensuring consistency for historical comparison.
• Provides high vertical resolution with temperature recorded at uniform 5-meter depth intervals.
• Covers a specific, documented time range from 1965-03-26 to 1965-04-30.

Limitations

• Key quantitative metrics like row count, file size, and specific column names are unavailable from all sources.
• The MBT instrument limits observations to the upper ocean, with a maximum depth of approximately 285 meters.
• Sources conflict on the last updated date, with one showing 2026-04-01 and another showing 1965-04-30.
