Discrete sample and profile data collected from the WECOMA and GYRE vessels in the North Pacific Ocean and South Pacific Ocean from February 1979 to June 1980. These data include dissolved inorganic carbon, alkalinity, temperature, salinity, dissolved oxygen, nitrate, nitrite, phosphate, and silicate. The data were collected by Taro Takahashi of Columbia University's Lamont-Doherty Earth Observatory as part of the FGGE_EQ_PAC_79-80 dataset.
Use Cases
- Analyze ocean carbon sequestration based on dissolved inorganic carbon and alkalinity measurements
- Study historical ocean acidification trends based on pH-related parameters
- Model marine biogeochemical cycles based on nutrient data (nitrate, phosphate, silicate)
- Assess ocean circulation and water mass properties based on temperature, salinity, and hydrostatic pressure profiles
Strengths
- Data covers a specific 16-month time range from 1979-02-07 to 1980-06-14
- Includes multiple key oceanographic variables: dissolved inorganic carbon, alkalinity, nutrients, temperature, and salinity
- Data originates from a named principal investigator (Taro Takahashi) and a recognized institution (Lamont-Doherty Earth Observatory)
Limitations
- Column-level documentation is absent; field semantics must be inferred after download
- Last updated 1980-06-14; freshness should be verified for modern applications
- Row count is unknown, which may limit suitability assessment
