Environmental indices for Pacific cod (Gadus macrocephalus) in the eastern Bering Sea from 1970-01-01 to 2020-12-31 (NCEI Accession 0290330)
This dataset includes surface and bottom temperature and pH values based on dynamically downscaled hindcasts (boundary conditions forced by CORE-CFS), historical runs (unique to each Earth System Model, and projections from the output of a high-resolution oceanographic model for the eastern Bering Sea at 10km horizontal resolution (Bering10K ROMSNPZ). Included are hindcasts of the physical and lower trophic level conditions in the region during 1970-2022, historical timeseries for each Earth System Model (1980 - 2015), and projected conditions under future emission scenarios from 2022 to 2079. The CMIP6 Earth System Models (i) downscaled through the ROMSNPZ Bering Sea model were GFDL-ESM4, CESM-CAM6, and MIROC-ES2L. The future CMIP6 emission scenarios (k) were Shared Socioeconomic Pathways 1-2.6. (ssp126) and 5-8.5 (ssp585), representing low and high emission scenarios, respectively. The first digit denotes the pathway number and the last two digits represent atmospheric radiation anomalies by 2100. The ssp126 and ssp585 scenarios correspond to future global mean radiation anomalies at the tropopause of 2.6 and 8.5 W/m2, respectively. These scenarios utilize the same set of hindcast values for the environmental variables for the years included in the stock assessment (1974-2022), but future environmental projections (2023-2079) differ by the emission scenarios (i.e., ssp126 and ssp585) and downscaled Earth System Model. The downscaled projections were bias corrected using the model hindcast output, prior to use as environmental variables beyond 2023.
