Description
From April to September 1994, surface underway data were collected aboard the NOAA Ship Malcolm Baldrige across the Banda Sea, Celebes Sea, Indian Ocean, Java Sea, Molucca Sea, North and South Pacific Ocean, and the South China Sea. The dataset includes measurements of carbon dioxide partial pressure, dissolved inorganic carbon, salinity, sea surface temperature, chlorophyll, nutrients, and other biological, chemical, and physical variables. These data were collected by Rik Wanninkhof of NOAA's Atlantic Oceanographic and Meteorological Laboratory during the DIC94, EQPAC_F94, and EQPAC_S94 cruises.
Use Cases
Modeling air-sea carbon dioxide flux based on partial pressure measurements in water and atmosphere.
Analyzing relationships between dissolved inorganic carbon and physical parameters like sea surface temperature and salinity.
Studying marine biogeochemistry based on nutrient (nitrate, phosphate, silicate) and chlorophyll measurements.
Calibrating or validating ocean carbon cycle models using in-situ underway data from specific cruises.
Strengths
Includes multiple carbon system variables (partial pressure of CO2, dissolved inorganic carbon) alongside complementary physical and nutrient data.
Data collected across a wide geographic area spanning the Pacific and Indian Oceans and adjacent seas.
Temporal coverage is clearly defined for three specific research cruises in 1994.
Limitations
Column-level documentation is absent; field semantics must be inferred after download.
Row count and file size are unknown, which may limit suitability assessment.
Data may reflect geographic and temporal bias inherent to the specific ship tracks and time period.
