Oceanographic CTD and Bottle Data from the Atlantic Ocean, July-August 2000

Chemical, physical, and profile data collected from the research vessel THALASSA in the Gulf of Guinea and the North and South Atlantic Ocean from July 24 to August 21, 2000. The dataset includes measurements of chlorofluorocarbons (CFC-11, CFC-12), dissolved oxygen, nitrate, phosphate, silicate, salinity, water temperature, and hydrostatic pressure. These data were collected by B. Bourles of the French National Research Institute for Sustainable Development using CTD and bottle instruments as part of the Equalant_2000_35TH20000724 cruise.

Use Cases

• Analyzing water mass age and ventilation rates based on CFC-11 and CFC-12 measurements.
• Studying ocean biogeochemistry and nutrient cycles based on nitrate, phosphate, and silicate data.
• Investigating physical oceanographic properties like density structure based on concurrent salinity, temperature, and pressure profiles.
• Calibrating or validating regional ocean models with in-situ hydrographic and chemical data.

Strengths

• Includes multiple key oceanographic variables (CFCs, nutrients, oxygen, temperature, salinity) measured concurrently.
• Data collection is temporally focused over a one-month cruise in 2000, providing a snapshot of ocean conditions.
• Spatial coverage spans multiple Atlantic Ocean regions: Gulf of Guinea, North Atlantic, and South Atlantic.

Limitations

• Last updated 2000-08-21 00:00:00; freshness should be verified.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
