Coastal Carbon Data: Surface Underway Measurements from CEFAS Endeavour

Surface underway measurements from the CEFAS Endeavour research vessel capture chemical, meteorological, and physical data in the English Channel, Irish Sea, St. George's Channel, North Sea, and North Atlantic Ocean. The dataset includes partial pressure of carbon dioxide in air and water, salinity, sea surface temperature, and barometric pressure, collected using CO2 gas analyzers and equilibrators. Data were gathered across multiple cruises between 2012 and 2013 by scientists from the Centre for Environment, Fisheries and Aquaculture Science.

Use Cases

• Calculating air-sea CO2 flux based on partial pressure differences.
• Assessing seasonal and spatial variability of coastal ocean carbon chemistry.
• Validating regional ocean carbon models with in-situ pCO2 measurements.
• Correlating sea surface temperature and salinity with carbon dioxide parameters.

Strengths

• Data collected using standardized instruments: Carbon dioxide (CO2) gas analyzer and Shower head chamber equilibrator.
• Covers multiple distinct geographic regions (English Channel, Irish Sea, North Sea, North Atlantic Ocean).
• Includes data from at least five separate research cruises, providing temporal coverage across 2012 and 2013.

Limitations

• Key metadata such as row counts, file sizes, and specific column names are unavailable across all platform entries.
• Dataset entries show conflicting 'last updated' dates (e.g., 2013-03-13 vs. 2026-03-06), creating uncertainty about versioning.
• Documentation gaps exist, as license and author details are consistently listed as unknown or null.
