Oceanographic Physical and Chemical Data from Argentine Waters

Argentine Oceanographic Data Centre (CEADO) provides physical-chemical and nutrient data from national and foreign research cruises. The dataset includes measurements of wind, waves, water temperature, salinity, oxygen, phosphates, nitrites, nitrates, silicates, pH, and alkalinity. Data were collected using standard instruments like Nansen casts, water samplers, and STD/CTD systems.

Use Cases

• Analyze correlations between water temperature, salinity, and nutrient levels like phosphates and nitrates to study ocean stratification.
• Model dissolved oxygen concentrations as a function of water temperature and salinity for hypoxia monitoring.
• Map spatial distributions of pH and alkalinity to assess ocean acidification trends in the Southern Ocean.
• Use wind and wave data alongside water color and transparency to validate satellite-derived ocean color products.

Strengths

• Data originates from a national oceanographic data center (CEADO) with a mandate for quality control.
• Covers multiple critical oceanographic parameters including physical, chemical, and nutrient variables.

Limitations

• Specific row count, temporal range, and spatial resolution of the data files are unknown.
• Potential for geographic bias, with focus on Argentine national interest areas in the SW Atlantic, SE Pacific, and Southern Ocean.
