Marine organism concentrations, carbonate chemistry variables, and nutrient concentrations from Atlantis ecosystem model simulation output in the California Current from 2013-01-01 to 2053-12-31 to understand vulnerability of California current food webs and economics to ocean acidification (NCEI Accession 0131198)

Metadata Updated: December 1, 2023

This dataset contains the model output of a study to evaluate likely economic and ecological outcomes of ocean acidification in the California Current. Specifically, we have archived netCDF output files from simulations that accomplish the following:

a) Use a Regional Ocean Modeling System (ROMS) to predict present and future spatial projections of ocean acidification, as well as salinity, currents, and upwelling. ROMS was coupled to global circulation models (GFDL ESM2M) and IPCC CO2 scenarios.

b) Build on previous literature reviews and ongoing experiments to develop scenarios for the biological response of calcifying benthic organisms (e.g., mollusks, clams, brittle stars) to pH.

c) Use an Atlantis ecosystem model to project these direct impacts of acidification on lower trophic levels, the resulting food web-mediated response of harvested and protected stocks, and catches by US West Coast fisheries. Atlantis is driven by dynamic, spatially explicit fields from ROMS. See "Technical Documentation" here: http://www.nwfsc.noaa.gov/research/divisions/cb/ecosystem/marineecology/aem.cfm

Four separate netCDF output files from Atlantis are provided here. They are 50 year projections of ecosystem model dynamics. These are 1) 2010sConditionsNopHResponse, which repeats or loops ocean conditions during the 2010s, with no effect of pH on organism biology 2) 2060sConditionsNopHResponse, which repeats or loops ocean conditions during the 2060s, with no effect of pH on organism biology 3) 2010sConditionsWithpHResponse, which repeats or loops ocean conditions during the 2010s, but with effect of pH on organism biology of calcifying benthic groups 4) 2060sConditionsWithpHResponse, which repeats or loops ocean conditions during the 2010s, with no effect of pH on organism biology.
