VOS Skogafoss Lines: Surface Ocean Carbon and Chemistry in the North Atlantic

North Atlantic Ocean and North Greenland Sea surface underway data from the vessel SKOGAFOSS, spanning 2003 to 2007. The dataset contains measurements of carbon dioxide partial pressure, dissolved inorganic carbon, alkalinity, nutrients, salinity, and temperature. These observations were collected as part of a sustained time-series effort to monitor ocean carbon uptake and acidification.

Use Cases

• Quantifying air-sea CO2 flux based on partial pressure difference measurements.
• Calibrating and validating ocean carbon cycle models using dissolved inorganic carbon and alkalinity data.
• Assessing seasonal and interannual variability in ocean acidification indicators across the North Atlantic.
• Analyzing correlations between nutrient concentrations (nitrate, phosphate, silicate) and biological productivity.
• Studying the physical drivers of carbon distribution using concurrent temperature and salinity profiles.

Strengths

• Covers a multi-year time series from 2003 to 2007, allowing for temporal trend analysis.
• Includes a wide suite of co-located chemical, physical, and meteorological variables relevant to the marine carbon cycle.
• Data collection follows a standardized methodology using specific instruments like CO2 gas analyzers and equilibrators, as described.
• Cross-platform presence on NASA Earthdata and Data.gov signals importance and validation.

Limitations

• Key metadata such as row counts, file size, and specific column names are consistently missing across all source entries.
• Conflicting 'last updated' dates (e.g., 2026-03-06 vs. 2007-06-04) create uncertainty about data currency and maintenance.
• Documentation gaps exist, as license and detailed authorship information are not provided.
