North Atlantic Ocean Temperature Profiles from DOLPHIN Cruise

1970-05-06 data contains temperature-depth profiles from the DOLPHIN cruise in the North Atlantic Ocean, processed by the National Oceanographic Data Center (NODC) into its standard C128 format. The dataset captures the thermal structure of the ocean's upper layers to a maximum depth of approximately 285 meters. It is provided by the National Oceanic and Atmospheric Administration.

Use Cases

• Analyzing vertical temperature gradients in the upper ocean at uniform 5-meter depth intervals.
• Studying historical sea surface temperature and subsurface thermal conditions for a specific date and location.
• Validating or calibrating ocean model simulations for the North Atlantic region using point-in-time profile data.
• Correlating cruise-reported metadata (date, position, time) with observed temperature-depth pairs.

Strengths

• Data is processed to a standardized NODC format (C128), ensuring a consistent structure for analysis.
• Provides precise temporal and spatial coverage for a single research cruise on 1970-05 06 in the North Atlantic Ocean.
• Temperature measurements are recorded at uniform depth intervals (5 m), facilitating direct vertical comparisons.

Limitations

• Conflicting metadata: one platform lists a last updated date of 2026-03-05, while another lists 1970-05-06, creating uncertainty about provenance timing.
• Limited vertical coverage to approximately 285 meters, restricting analysis to the ocean's upper layers only.
• Key technical details like row count, file size, specific column names, and license are unavailable from all sources.
