North Atlantic Ocean Temperature Profiles from LYNCH Cruise

6900594 is a processed dataset of bathythermograph (XBT) temperature-depth profiles collected from the research vessel LYNCH in the North Atlantic Ocean. The data was processed by the National Oceanographic Data Center (NODC) into the C116/C118 standard format, which records temperature at non-uniform inflection points to define the temperature curve. It represents a specific cruise from June 27 to July 6, 1969, and is managed 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 cruise in June-July 1969.
• Comparing historical XBT data collection and processing methods (C116 format) to modern standards.
• Investigating temperature inflection points at non-uniform depths to model thermal curves.

Strengths

• Data is processed to a recognized NODC standard format (C116/C118) for consistency.
• Provides specific cruise, position, date, and time metadata for each observation.
• Covers a defined 10-day time range from 1969-06-27 to 1969-07-06.
• Profiles can reach depths of 450m, 760m, or up to 1830m with special instruments.

Limitations

• No column names, row counts, or file size information are provided by any source.
• The dataset is historical, with the last substantive data collection date being 1969-07 06.
• Sources conflict on the 'last updated' metadata, with one listing 2026-04-01 (likely administrative) and another 1969-07-06.
