Dissolved Inorganic Carbon and Oceanographic Measurements from North Atlantic Cruise

Oceanographic measurements include dissolved inorganic carbon, dissolved oxygen, hydrostatic pressure, potential temperature, salinity, and water temperature. Data were collected from the OCEANUS research vessel during a cruise in the North Atlantic Ocean from May 29 to June 3, 1995. The dataset was compiled by Taro Takahashi of Columbia University's Lamont-Doherty Earth Observatory and R. Pickart as part of the CARINA synthesis project.

Use Cases

• Analyze dissolved inorganic carbon concentrations alongside salinity and temperature to study carbon system variability.
• Correlate hydrostatic pressure and water temperature profiles to understand physical oceanographic conditions.
• Use dissolved oxygen measurements with potential temperature data for biogeochemical investigations of ocean metabolism.
• Map the spatial distribution of collected variables across the North Atlantic Ocean cruise track.

Strengths

• Data originates from a specific, documented research cruise (CARINA/32OC19950529) providing clear provenance.
• Includes multiple core oceanographic variables (DIC, oxygen, temperature, salinity, pressure) for integrated analysis.
• Part of the CARINA international synthesis project, aiming for internally consistent, merged data for biogeochemical studies.

Limitations

• Temporal coverage is extremely limited, spanning only a 5-day cruise in 1995.
• Geographic scope is restricted to a single cruise track in the North Atlantic Ocean.
• Specific sample size, row count, and data granularity (e.g., depth resolution) are unknown.
