VOS_JHjort_2008: Surface Ocean Carbon and Physical Properties

NCEI Accession 0157398 contains surface underway chemical and physical data from the research vessel JOHAN HJORT. The dataset includes measurements of dissolved oxygen, partial pressure of carbon dioxide in air and water, salinity, and sea surface temperature collected in the Barents Sea, North Sea, Norwegian Sea, and Skagerrak between November 2007 and June 2008. Data were collected by researchers from the University of Bergen and the Bjerknes Centre for Climate Research using carbon dioxide gas analyzers, equilibrators, and thermosalinographs.

Use Cases

• Calculating air-sea CO2 flux based on partial pressure measurements in water and atmosphere.
• Analyzing correlations between sea surface temperature, salinity, and dissolved oxygen concentrations.
• Validating regional ocean carbon cycle models using in-situ surface underway observations.
• Studying seasonal variability of marine carbon parameters in high-latitude seas.

Strengths

• Data collected via specific, named instruments (CO2 gas analyzer, shower head chamber equilibrator, thermosalinographs).
• Clear provenance from a recognized research institution (University of Bergen, Bjerknes Centre).
• Well-defined temporal coverage from 2007-11-15 to 2008-06-08.
• Cross-platform presence (Data.gov, NASA Earthdata) suggests validation and reuse.

Limitations

• Key metadata is missing: exact row count, file size, column names, and license are unknown.
• The dataset's freshness is unclear; the underlying data is from 2008, though metadata was updated in 2026.
• Documentation gaps exist, as only a general description is provided without detailed data dictionary.
