North Atlantic Ocean Temperature Profiles from R/V Knorr 1970

June 28 to July 9, 1970, this dataset contains mechanical bathythermograph (MBT) data from the R/V Knorr cruise in the North Atlantic Ocean. It provides temperature-depth profile pairs recorded at uniform 5-meter intervals, processed by the National Oceanographic Data Center (NODC) into the standard C128 format. The data is managed by the National Oceanic and Atmospheric Administration.

Use Cases

• Analyzing the thermal structure of the upper ocean (up to ~285m) using temperature-depth pairs.
• Studying short-term oceanographic variability during a specific cruise using date, time, and position data.
• Calibrating or validating models of upper-ocean heat content for a defined region and time period.
• Investigating historical instrument performance and data standardization via the NODC C128 format.

Strengths

• Data is processed to a known standard format (NODC C128) ensuring consistent structure.
• Provides precise temporal coverage for a 12-day research cruise in June-July 1970.
• Temperature measurements are recorded at a consistent, fine vertical resolution of 5-meter intervals.

Limitations

• Key metadata such as row count, column names, and exact file size are unavailable from all sources.
• Instrument limitation restricts observations to a maximum depth of approximately 285 meters, capturing only the upper ocean.
• Sources conflict on the dataset's last updated date (2026-03-05 vs. 1970-07-09), creating uncertainty about maintenance.
