1994 to 2006 measurements of ocean temperature, salinity, oxygen, and pressure collected by profiling floats worldwide. The dataset is archived by the U.S. National Oceanographic Data Center (NODC) as part of the Global Argo Data Repository for the International Global Argo Project. Data archiving began on a weekly basis starting in the second quarter of FY 2003.
Use Cases
- Analyze temporal trends in ocean temperature and salinity profiles to study climate change impacts.
- Model the relationship between pressure, temperature, and salinity to validate oceanographic equations of state.
- Map the global distribution of dissolved oxygen levels from float profiles to identify hypoxic zones.
- Correlate conductivity measurements with salinity readings for sensor calibration and quality control.
Strengths
- Data collection spans 12 years from 1994 to 2006, providing a multi-year time series.
- Global spatial coverage from profiling floats deployed in the world's oceans.
- Includes multiple core oceanographic variables: temperature, salinity, oxygen, and pressure.
Limitations
- The dataset is temporally stale, with the last update recorded in June 2006.
- Specific sample size, row count, and data volume are unknown.
- Potential for missing or irregular data points due to the autonomous nature of float deployments.
