California Current Ecosystem Model Projections for Ocean Acidification, 2013-2053

Model output from a study evaluating economic and ecological outcomes of ocean acidification in the California Current. The archival package contains four separate NetCDF files from Atlantis ecosystem model simulations, representing 50-year projections from 2013-01-01 to 2053-12-31. The data originates from NOAA NCEI and was last updated in May 2026.

Use Cases

• Projecting direct impacts of changing pH on calcifying benthic organisms based on biological response scenarios.
• Analyzing food web-mediated responses of harvested and protected fish stocks based on Atlantis ecosystem model dynamics.
• Evaluating potential future catches by US West Coast fisheries based on coupled ROMS and global circulation model projections.
• Comparing ecosystem states under different ocean acidification scenarios (e.g., with and without pH effects) based on the four provided simulation files.

Strengths

• Provides 50-year projections of ecosystem dynamics, covering a long-term future period from 2013 to 2053.
• Includes four distinct simulation scenarios allowing for controlled comparison of pH effects and time periods.
• Based on a coupled modeling approach integrating Regional Ocean Modeling System (ROMS) and Atlantis ecosystem models.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic and modeling bias inherent to the California Current region and the Atlantis/ROMS framework.
