Atlantic Ocean XBT Temperature Profiles from CHAIN Cruise 1973

Temperature-depth profile data collected using expendable bathythermograph (XBT) casts from the R/V CHAIN in the Atlantic Ocean during May-June 1973. The data were submitted by the Woods Hole Oceanographic Institution as part of the IDOE/MODE project and processed by NODC into the Universal Bathythermograph Output (UBT) format. Profiles contain non-uniform depth measurements recorded at inflection points to define the temperature curve, with potential depths reaching 1830 meters.

Use Cases

• Analyzing vertical temperature structure in the Atlantic Ocean using paired temperature-depth values.
• Studying oceanographic conditions during the 1973 MODE experiment using cruise, position, date, and time metadata.
• Comparing XBT inflection-point sampling methodology against uniform-depth MBT data for profile accuracy.

Strengths

• Data is part of a major international oceanographic project (IDOE/MODE), indicating scientific importance.
• Profiles use inflection-point sampling to accurately define the temperature curve with minimal data points.
• Data is processed to a recognized standard format (NODC UBT) and is hosted on multiple authoritative platforms.

Limitations

• Specific column names, row counts, and dataset size are unknown across all sources.
• There is a conflict in the reported temporal coverage: one source lists 1973, while the title suggests 1975.
• License information is not provided, restricting clarity on reuse terms.
