NOAA Ship Delaware II XBT Temperature-Depth Profiles from 1984

North Atlantic Ocean temperature-depth profiles collected via expendable bathythermograph (XBT) from NOAA Ship Delaware II during a cruise from August 7 to 17, 1984. Data was processed by the National Oceanographic Data Center (NODC) into the standard C116 format, which records non-uniform depth inflection points to define the temperature curve. The dataset is published by the National Oceanic and Atmospheric Administration.

Use Cases

• Analyzing vertical temperature structure in the North Atlantic using paired temperature-depth values.
• Studying short-term oceanographic conditions during a specific NOAA cruise in August 1984.
• Comparing historical XBT data collection methods (inflection points) with modern uniform-depth profiling.

Strengths

• Data is processed to a recognized NODC standard format (C116/C118) for historical XBT data.
• Provides precise temporal (1984-08-07 to 1984-08-17) and geographic (North Atlantic Ocean) scope for the profiles.
• Dataset is maintained by a major national agency (NOAA) and appears on multiple government data platforms.

Limitations

• Specific row count, column names, and file size are unknown from all provided sources.
• Data is historical, with a narrow 10-day collection window from 1984.
