Atlantic Explorer Surface Ocean Chemistry, 2019

From May 27 to December 11, 2019, this dataset contains surface underway measurements from R/V Atlantic Explorer cruises in the North Atlantic Ocean. It includes sea surface temperature, salinity, oxygen, and mole fraction of carbon dioxide (xCO2) in both water and atmosphere, alongside related pressure and temperature readings. The data were collected using specific instruments including a GO Oceanics Equilibrator, conductivity sensor, and oxygen optode.

Use Cases

• Calculating air-sea CO2 flux based on measured mole fraction of carbon dioxide (xCO2) and barometric pressure.
• Analyzing coastal ocean acidification trends using sea surface salinity, temperature, and xCO2 data.
• Calibrating or validating biogeochemical ocean models with in-situ measurements of oxygen and carbon chemistry.
• Studying physical-biogeochemical coupling by examining concurrent records of sea surface temperature and salinity.

Strengths

• Provides a continuous, multi-month time series from May to December 2019.
• Includes directly measured, co-located parameters critical for carbon flux calculation (xCO2, temperature, pressure).
• Documents the specific instruments used for collection (e.g., GO Oceanics Equilibrator, Setra Pressure sensor).

Limitations

• Column names and precise data structure are not provided in any source description.
• Conflicting 'last updated' dates (2026-03-05 vs. 2019-12-11) create uncertainty about metadata maintenance.
• No row counts, file sizes, or license information are available from any platform.
