Saildrone 1007: Surface Ocean Carbon and Physical Measurements in the South Pacific, 2018

Surface underway chemical, meteorological and physical data were collected by an Autonomous Surface Vehicle (Saildrone 1007) in the South Pacific Ocean and Tasman Sea. The dataset includes measurements of carbon dioxide fugacity, mole fraction, sea surface temperature, salinity, dissolved oxygen, and pH from March 27 to May 31, 2018. These data were collected by the National Oceanic and Atmospheric Administration using instruments like a CO2 gas analyzer, thermosalinographs, and an oxygen meter.

Use Cases

• Modeling air-sea CO2 flux based on Delta fCO2 (fCO2_WET_SW - fCO2_WET_AIR) measurements.
• Analyzing correlations between sea surface temperature, salinity, and carbon dioxide parameters.
• Calibrating and validating satellite-derived sea surface temperature and salinity products with in-situ measurements.
• Studying ocean acidification trends using total pH surface water data alongside fCO2_WET_SW.

Strengths

• Data includes simultaneous measurements of multiple parameters (pCO2, temperature, salinity, O2, pH) for integrated analysis.
• Collected via an autonomous platform (Saildrone) enabling continuous surface underway sampling over a two-month period.
• Specific instrument details are provided, including bubble type equilibrator, carbon dioxide gas analyzer, and thermosalinographs.

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 the single Saildrone mission track in the South Pacific.
