Carbonate Chemistry and Water Isotopes from 16 Greenland Fjords, 2016 and 2018

52 sample sites across 16 Greenlandic fjords provide measurements of dissolved inorganic carbon, total alkalinity, and δ18O-H2O from August 2016 and 2018 cruises. The dataset was collected by Henry C. Henson of Aarhus University and funded by the Danish Centre for Marine Science and EU Horizon 2020 projects. It represents the first large-scale analysis of carbonate system parameters in Greenland coastal waters.

Use Cases

• Modeling the impact of glacial meltwater on coastal carbonate chemistry based on δ18O-H2O and DIC/TA measurements.
• Assessing the acidification state and CO2 uptake potential of Greenland fjords based on carbonate system parameters.
• Studying the link between fjord circulation changes and biogeochemistry based on combined cruise datasets from East and West Greenland.

Strengths

• 52 carbonate chemistry sample sites provide a wide-scale spatial snapshot.
• Triplicate exetainers were collected for DIC and TA at each depth, suggesting methodological rigor.
• Measurements were verified using Certified Reference Materials from Scripps Institution of Oceanography.

Limitations

• Row count and specific column definitions are unknown, limiting suitability assessment.
• Data is limited to two August cruises in 2016 and 2018, representing a specific seasonal snapshot.
• Environmental variables like CTD data are stored in separate datasets, requiring joins for full analysis.
