SONNE Cruise 113/1: Surface Carbon Dioxide Fugacity and Oceanic Variables

Surface underway data from the SONNE cruise 113/1 (06BE19961009) in the North Pacific Ocean and Philippine Sea spans from October 9 to October 30, 1996. The dataset includes measurements of barometric pressure, partial pressure of carbon dioxide in air and water, salinity, and sea surface temperature collected using a CO2 gas analyzer. These observations were collected by Arne Körtzinger of GEOMAR Helmholtz Centre for Ocean Research Kiel.

Use Cases

• Calculating air-sea CO2 flux based on partial pressure measurements in air and water.
• Analyzing oceanic carbon uptake variability using salinity and sea surface temperature data.
• Studying regional atmospheric conditions via barometric pressure readings.
• Validating ocean carbon cycle models with in-situ fugacity of carbon dioxide data.

Strengths

• Data covers a specific 22-day cruise with precise start (1996-10-09) and end (1996-10-30) dates.
• Includes fugacity of carbon dioxide measurements for both atmosphere and water, a key variable for carbon flux studies.
• Dataset is hosted on multiple authoritative platforms (Data.gov and NASA Earthdata), indicating curation and importance.

Limitations

• Column names and exact row count are unknown, limiting detailed structural understanding.
• Metadata for license, author, and size is incomplete or missing across all sources.
• The dataset is historical (1996) and may not reflect current conditions or measurement standards.
