Argo Float Ocean Temperature and Salinity Measurements from Canada

Argo Canada provides data from approximately 4,000 autonomous floats reporting on ocean conditions. The dataset includes temperature and salinity measurements, with some floats collecting additional biological and chemical properties. Data is made publicly available within 24 hours of collection for climate and oceanographic research.

Use Cases

• Analyze ocean temperature and salinity time series data to assess regional climate change impacts.
• Model oceanographic processes using float-reported temperature and salinity profiles.
• Study the hydrological cycle by examining spatial and temporal patterns in salinity data.
• Integrate biological and chemical property data from select floats into marine ecosystem models.

Strengths

• Data is reported by a global array of approximately 4,000 autonomous instruments.
• Information is made publicly available within 24 hours of collection, ensuring timeliness.
• The program represents an international collaboration involving more than 30 nations.

Limitations

• The specific number of data rows and columns per record is not provided in the input.
• The exact geographic distribution of the 4,000 floats relative to Canada is not specified.
