Pacific Ocean Hydrographic Profile Data from GO-SHIP Section P18, 2016-2017

Profile discrete measurements of temperature, salinity, oxygen, nutrients, chlorofluorocarbons, dissolved inorganic carbon, total alkalinity, pH, and dissolved organic carbon collected during a NOAA research cruise. The data were obtained along the GO-SHIP Repeat Hydrography Section P18 in the Pacific Ocean from November 19, 2016, to February 3, 2017. This occupation was conducted by NOAA Ship Ronald H. Brown under the Global Ocean Ship-based Hydrographic Investigations Program.

Use Cases

• Modeling ocean carbon uptake and acidification based on dissolved inorganic carbon and pH measurements
• Analyzing water mass age and circulation based on chlorofluorocarbon (CFC) tracer data
• Studying biogeochemical cycles and nutrient distributions based on oxygen and nutrient profiles
• Calibrating and validating oceanographic models based on high-precision temperature and salinity data

Strengths

• Includes a wide range of chemical and physical parameters, such as dissolved inorganic carbon, total alkalinity, and chlorofluorocarbons
• Data collected as part of the standardized GO-SHIP Repeat Hydrography program, suggesting consistent methodology
• Covers a specific transect (Section P18) in the Pacific Ocean over a defined period from 2016-11 19 to 2017-02-03

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 ship track over a limited time period
