CLIVAR P02: North Pacific Ocean Carbon and Hydrographic Measurements from 2004

R/V Melville cruise P02 collected over 20 oceanographic variables, including dissolved inorganic carbon, alkalinity, and chlorofluorocarbons, in the North Pacific and Philippine Sea during 2004. The data were gathered by NOAA PMEL, Scripps, and RSMAS scientists using CTDs, Niskin bottles, and specialized titrators and coulometers. This dataset supports the CLIVAR program's goal to quantify changes in ocean heat, freshwater, and CO2 storage.

Use Cases

• Modeling ocean carbon uptake and storage based on DIC and alkalinity measurements
• Analyzing water mass age and circulation using chlorofluorocarbon (CFC) and helium/tritium tracer data
• Studying biogeochemical cycles from nutrient and dissolved organic carbon (DOC) profiles
• Calibrating satellite-derived ocean color products with in-situ CDOM measurements

Strengths

• Includes over 20 distinct chemical and physical variables, such as delta carbon-13/14, neon, and tritium
• Data collected by recognized institutions (NOAA PMEL, Scripps, RSMAS) using specific instruments like alkalinity titrators and coulometers
• Covers a specific temporal range from 2004-06-15 to 2004-08-27 in the North Pacific and Philippine Sea

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment for large-scale modeling
• Data may reflect geographic and temporal bias inherent to a single 2004 cruise
