From February to November 2008, surface underway measurements of carbon dioxide and related variables were collected aboard the NOAA Ship KA'IMIMOANA in the Pacific Ocean. The data include partial pressure of carbon dioxide in air and water, salinity, sea surface temperature, and barometric pressure. It was collected by researchers from the NOAA Pacific Marine Environmental Laboratory as part of the VOS_Ka'imimoana_2008 dataset.
Use Cases
- Modeling air-sea carbon dioxide flux based on partial pressure differences.
- Analyzing seasonal variability of surface ocean carbon chemistry in the Pacific Ocean.
- Calibrating or validating satellite-derived sea surface temperature and salinity products.
- Studying correlations between barometric pressure and oceanic carbon dioxide measurements.
Strengths
- Data covers a specific time range from 2008-02-02 to 2008-11-16 across multiple Pacific Ocean regions.
- Includes multiple related chemical and physical variables measured simultaneously from a single platform.
- Associated with seven distinct cruise IDs (KA2008_01 through KA2008_07), suggesting structured data collection.
Limitations
- Description metadata is limited; actual data quality requires manual inspection after download.
- Last updated 2008-11-16 00:00:00; freshness should be verified.
- Column-level documentation is absent; field semantics must be inferred after download.
