Ocean Bottom Temperature Time Series at St. Anns Bank Marine Protected Area

Daily area-averaged ocean bottom temperature data derived from two numerical models for the St. Anns Bank Marine Protected Area. The dataset combines a 1/36° resolution model covering 2016-2023 with a 1/12° reanalysis product spanning 1993-2023, validated against in-situ observations. It was published by Fisheries and Oceans Canada in August 2024 to analyze temperature changes over 8 and 30-year periods.

Use Cases

• Analyze daily bottom temperature trends from 1993 to 2023 to study long-term ocean warming in the Marine Protected Area.
• Compare temperature outputs from the high-resolution 1/36° CIOPS-E model and the 1/12° GLORYS12 reanalysis to assess model performance.
• Validate model-derived daily area averages against in-situ observation data for accuracy assessment.
• Investigate seasonal and interannual bottom temperature variability within the St. Anns Bank Marine Protected Area.

Strengths

• Provides a 30-year temporal record from 1993 to 2023 from the GLORYS12 model.
• Includes high-resolution data from a 1/36° horizontal grid model for the 2016-2023 period.
• Data is validated against in-situ observations, supporting its reliability.
• Combines outputs from two established numerical modeling systems (CIOPS-E and GLORYS12).

Limitations

• Spatial coverage is limited to a single Marine Protected Area (St. Anns Bank), restricting broader regional analysis.
• The higher-resolution CIOPS-E model data covers only 8 years (2016-2023), a shorter period than the full reanalysis.
• As a derived product of daily area averages, the original high-resolution spatial grid data is not provided.
