Coastal Water Temperature Monitoring in the Southern Gulf of St. Lawrence

Bottom and surface water temperatures are recorded every two hours in coastal waters of the southern Gulf of St. Lawrence. The data is collected by Fisheries and Oceans Canada using electronic devices attached to buoys or moorings, with quality checks performed for irregularities. The dataset was last updated on 2026-05-01.

Use Cases

• Modeling coastal water temperature trends based on the two-hour recording interval.
• Analyzing the impact of temperature fluctuations on marine species as described in the program's purpose.
• Studying spatial temperature variations in the southern Gulf of St. Lawrence based on point spatial data.

Strengths

• Data undergoes quality control checks for irregularities as noted.
• Temperature is recorded at a high temporal resolution of every two hours.
• Collection involves multiple sources including fishermen, DFO staff, and the Canadian Coast Guard since 2000.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
