North Atlantic Ocean Temperature Profiles from R/V Knorr 1971

285 meters is the maximum depth of temperature observations in this dataset. It contains bathythermograph (MBT) data collected by the R/V Knorr in the North Atlantic Ocean over a nine-day period in January 1971. The National Oceanographic Data Center (NODC) processed the data into its standard C128 format.

Use Cases

• Analyzing the vertical thermal structure of the upper ocean up to 285m depth using temperature-depth value pairs.
• Studying short-term temperature variability in a specific North Atlantic region from January 19-27, 1971.
• Correlating temperature profiles with cruise metadata including date, position, and time for each observation.
• Using as a historical baseline for comparison with modern ocean temperature datasets in similar regions.

Strengths

• Data is formatted to a recognized standard (NODC C128 format) ensuring consistent structure.
• Temperature values are recorded at uniform 5-meter depth intervals, facilitating systematic analysis.
• Each observation is accompanied by cruise information, date, position, and time, providing essential spatial-temporal context.

Limitations

• The dataset's row count, total size, and specific column names are not provided by any source.
• MBT instrument limitations restrict observations to a maximum depth of approximately 285 meters, capturing only the upper ocean layer.
• Sources conflict on the 'last updated' metadata, with dates ranging from 1971-01-27 to 2026-03-05.
