GLODAPv2 Cruise: CTD and Bottle Measurements in the Philippine Sea

Discrete sample and profile data were collected from the RYOFU MARU research vessel in the Philippine Sea during a cruise from February 10 to February 17, 1992. The dataset includes measurements of dissolved oxygen, hydrostatic pressure, nitrate, nitrite, salinity, water temperature, and phosphate. Data were gathered using CTD and bottle instruments by the Japan Meteorological Agency as part of the GLODAPv2 project.

Use Cases

• Analyzing vertical profiles of salinity and temperature based on CTD measurements.
• Studying nutrient distributions (nitrate, nitrite, phosphate) based on discrete bottle samples.
• Calculating dissolved oxygen concentrations for ocean health assessments.
• Integrating cruise data into larger ocean carbon and acidification databases like GLODAPv2.

Strengths

• Data originates from a specific research cruise with a precise time range (1992-02-10 to 1992-02-17).
• Includes multiple key oceanographic variables measured with standard instruments (CTD and bottle).
• Part of the GLODAPv2 project, a recognized international ocean carbon data synthesis.

Limitations

• Column names and dataset size (rows) are unknown across all sources.
• License information is not provided.
• The last updated metadata date conflicts between sources (1992-02-17 and 2026-03-05).
