Yellowfin Ship Upper Ocean Temperature Profiles 1950-1955

1950-05-12 to 1955-11-21 temperature-depth profiles from the Yellowfin ship in the North Pacific Ocean. The dataset contains mechanical bathythermograph (MBT) observations processed into the NODC C128 standard format, with temperature recorded at uniform 5-meter intervals down to a maximum depth of approximately 285 meters. It was collected and processed by the National Oceanographic Data Center (NODC) under the National Oceanic and Atmospheric Administration.

Use Cases

• Analyzing thermal structure of the upper ocean layer using paired temperature-depth values.
• Studying historical ocean temperature variability over a 5-year period using time-series data.
• Mapping spatial temperature distribution in the North Pacific using reported position (latitude/longitude) data.
• Correlating cruise information, date, and time with observed temperature profiles for specific research voyages.

Strengths

• Provides a continuous 5-year time series from 1950 to 1955 for temporal analysis.
• Data is standardized in the NODC C128 format, ensuring consistent structure and units.
• Includes core metadata for each observation: cruise information, date, position, and time.

Limitations

• Maximum observation depth is approximately 285 meters, limiting analysis to the upper ocean only.
• Sources conflict on last update date: one reports 2026-04-01, another reports the final observation date of 1955-11-21.
