Iceland Sea LN6 Time Series: Ocean Carbon Chemistry Profiles

Discrete oceanographic measurements from the Iceland Sea (LN6) time series cover a 28-year period from 1985 to 2013. The data includes partial pressure of carbon dioxide, dissolved inorganic carbon, temperature, salinity, nutrients, and dissolved oxygen. Observations were collected from profile and discrete samples during cruises of the R/Vs Arni Fridriksson and Bjarni Saemundsson.

Use Cases

• Tracking ocean acidification trends based on partial pressure of carbon dioxide and dissolved inorganic carbon measurements.
• Analyzing nutrient cycles (e.g., nitrate, silicate, phosphate) in relation to primary productivity.
• Calibrating ocean carbon models using long-term, in-situ time-series data from a specific basin.
• Studying the relationship between physical parameters (temperature, salinity) and dissolved oxygen levels over decades.

Strengths

• Covers a long temporal range of 28 years (1985-02-22 to 2013-11-26).
• Includes multiple key variables for ocean carbon and acidification studies.
• Data is hosted on multiple authoritative platforms (NASA Earthdata, Data.gov), indicating validation and importance.

Limitations

• Column names and precise data structure are not provided in any source, hindering immediate analysis.
• Conflicting 'last updated' dates (2013-11-26 vs. 2026-03-06) create uncertainty about metadata freshness.
• Key metadata such as row count, file size, and license are consistently reported as unknown or null.
