Placentia Bay CTD Moorings: Hourly Oceanographic Data from 2020-2023

Three moored CTDs in Placentia Bay collected hourly recordings of conductivity, temperature, and pressure from 2020 to November 2021. From 2021 through 2023, the instruments expanded to collect year-round, hourly data on temperature, conductivity, pressure, dissolved oxygen, and chlorophyll-a, with acoustic releases also recording ambient noise. This project was completed by the Coastal Environmental Baseline Program within Fisheries and Oceans Canada.

Use Cases

• Modeling seasonal water temperature cycles based on hourly time-series data.
• Analyzing relationships between chlorophyll-a levels and other water quality parameters like dissolved oxygen.
• Studying ambient underwater noise patterns based on acoustic release data.
• Mapping spatial variations in oceanographic conditions across Placentia Bay based on site locations.

Strengths

• Hourly temporal resolution provides detailed time-series for analysis.
• Data collection spans multiple years (2020-2023), allowing for trend analysis.
• Includes multiple physical and biological parameters: temperature, conductivity, pressure, dissolved oxygen, and chlorophyll-a.

Limitations

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