CEND Cruises: Coastal Carbon Dioxide and Sea Surface Data

From 2012-02-18 to 2015-10-21, this dataset contains surface underway measurements from the R/V Cefas Endeavour CEND coastal cruises in the North Atlantic Ocean, English Channel, and North Sea. It includes the partial pressure of carbon dioxide (pCO2) in air and water, sea surface temperature, and sea surface salinity. The data were collected using a carbon dioxide gas analyzer and a shower head chamber equilibrator.

Use Cases

• Calculating air-sea CO2 flux based on partial pressure difference measurements.
• Analyzing seasonal or spatial variability of coastal carbon dioxide concentrations.
• Correlating sea surface temperature and salinity with pCO2 levels.
• Validating regional ocean carbon cycle models with in-situ underway data.

Strengths

• Data spans multiple years (2012 and 2015), allowing for temporal analysis.
• Provides direct, in-situ measurements of key carbon cycle variables from specific research cruises.
• Hosted on multiple authoritative platforms (NASA EarthData, Data.gov), indicating validation and importance.

Limitations

• Conflicting temporal coverage: sources disagree on whether the data is from 2012 only or spans 2012-2015.
• Sparse metadata: column names, row counts, file sizes, and license information are not provided in any source.
• Documentation gaps: specific instrument models and detailed data processing methods are not described.
