Ocean Temperature Profiles from YAQUINA Cruise 1975

Temperature-depth profiles from the upper ocean were collected using a Mechanical Bathythermograph (MBT) during the YAQUINA cruise in the North Pacific Ocean. The dataset contains observations recorded at uniform 5-meter depth intervals up to approximately 285 meters. Data was processed by the National Oceanographic Data Center (NODC) into its standard C128 format and is provided by the National Oceanic and Atmospheric Administration.

Use Cases

• Analyzing the vertical temperature gradient in the upper 285 meters of the ocean.
• Studying short-term thermal variability during a specific cruise from March 12-17, 1975.
• Validating or calibrating ocean mixed-layer models using in-situ profile data.
• Examining the relationship between cruise location, time, and observed temperature at defined depth intervals.

Strengths

• Data is structured to the documented NODC standard C128 format, ensuring consistent interpretation.
• Temperature values are recorded at uniform 5-meter depth intervals, facilitating systematic analysis.
• Each observation includes associated cruise information, date, position, and time for contextual analysis.
• Dataset presence on multiple government platforms signals its curated status and archival importance.

Limitations

• The exact row count, column names, and total dataset size are not provided by any source.
• MBT instrument limits observations to a maximum depth of ~285m, restricting study to the ocean's upper layers.
• Sources conflict on the 'last updated' metadata, reporting dates from 1975 to 2026.
