Climate Projections for Six Maritime Marine Protected Areas, 2020-2099

Six key ocean variables, including temperature and salinity, are projected for six Marine Protected Areas using 22 CMIP6 models under four emissions scenarios. The dataset provides ensemble summary statistics for four 20-year periods from 2020 to 2099. Fisheries and Oceans Canada published this data in May 2026.

Use Cases

• Projecting future ocean temperature and salinity changes based on the six described variables
• Assessing climate change impacts on marine ecosystems based on multi-model ensemble projections
• Comparing future oceanographic conditions across different emissions scenarios (SSP1-2.6 to SSP5-8.5)
• Analyzing spatial climate trends within specific Marine Protected Areas like the Gully or St. Anns Bank

Strengths

• Projections are based on 22 CMIP6 climate models, providing a multi-model ensemble
• Covers four distinct emissions scenarios and four 20-year future time periods
• Focuses on six specific Marine Protected Areas in the Maritimes region

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download
• Column-level documentation is absent; field semantics must be inferred after download
