North Atlantic Ocean Geochemical Profiles from 2010 GEOTRACES Cruise

North Atlantic Ocean geochemical data from the R/V Pelagia GEOTRACES cruise PE319 in 2010. The dataset contains discrete profile measurements of dissolved inorganic carbon, total alkalinity, water temperature, salinity, dissolved oxygen, and nutrient concentrations. It was collected by the National Oceanic and Atmospheric Administration during a month-long expedition from April to May 2010.

Use Cases

• Analyze correlations between dissolved inorganic carbon (DIC) and water temperature or salinity to study ocean acidification drivers.
• Model nutrient cycles by examining relationships between phosphate, silicate, nitrate, and nitrite concentrations across ocean profiles.
• Use chlorofluorocarbon (CFC-11, CFC-12) measurements as tracers for ocean ventilation and water mass age estimation.
• Investigate the coupling of dissolved organic carbon (DOC) with other biogeochemical parameters like dissolved oxygen and nutrients.

Strengths

• Includes a multi-parameter suite of 12+ key oceanographic variables for biogeochemical analysis.
• Data originates from a focused GEOTRACES cruise, ensuring methodological consistency for the North Atlantic region.
• Provides discrete profile measurements, allowing for high vertical resolution of water column properties.

Limitations

• The dataset is limited to a single cruise over one month, offering only a temporal snapshot without seasonal or interannual context.
• Unknown row count and sample size prevent assessment of statistical power for spatial or depth-based analyses.
• Data is provided in HTML format, which is non-standard for scientific analysis and may require parsing and conversion.
