CCS Projections for groundfish
Listed in NOAA Oceanview
Groundfish species in the California Current System (CCS) are both ecologically and economically important, supporting valuable commercial fisheries.
Description
This dataset includes the projected catch-per-unit-effort (CPUE; kg/km2) for two groundfish species (lingcod, Ophiodon elongatus, and petrale sole, Eopsetta jordani) in this complex, using three high-resolution (~10 km) downscaled ocean projections under the Representative Concentration Pathway 8.5 (RCP8.5).
Spatially explicit species distribution models (SDMs) were previously trained and validated using CPUE data from a fishery-independent bottom trawl survey conducted by NOAA Northwest Fisheries Science Center (described in Liu et al. 2023). SDMs were fit using generalized linear mixed models (GLMMs) through the R package 'sdmTMB" (Anderson et al. 2022). The environmental covariates (bottom oxygen and bottom temperature) were sourced from a high-resolution Regional Ocean Modeling System (ROMS) developed at the University of California - Santa Cruz (Veneziani et al. 2009).

The environmental variables were extracted from a historical reanalysis (1980-2010) across a domain of 30°-48°N, inshore of 134°W at 0.1° horizontal resolution. To force the projections, daily output from the three dynamically downscaled ocean projections for the CCS were used. These downscaled projections are based on an implementation of the same 0.1° ROMS domain described above, with bias-corrected forcing obtained from three earth system models (ESMs) for the period from 1980 to 2100 under the RCP8.5 climate scenario (Pozo Buil et al., 2021).
Downscaled ESMs were selected to span the range of plausible futures for the CCS, and belong to the phase 5 of the coupled model intercomparison project (CMIP5) archive: the Geophysical Fluid Dynamics Laboratory (GFDL) ESM2M, Institut Pierre-Simon Laplace (IPSL) CM5A-MR and the Hadley Center HadGEM2-ES (HAD).
