This data set belongs to "21st-century environmental change decreases habitat overlap of Antarctic toothfish (Dissostichus mawsoni) and its prey" by Cara Nissen, Jilda Alicia Caccavo and Anne L. Moree (accepted for publication in "Global Change Biology") Contact: cara.nissen@colorado.edu The data provided here are post-processed from the raw FESOM1.4-REcoM2 model output which can be obtained at the World Data Center for Climate (WDCC): https://www.wdc-climate.de/ui/project?acronym=HighRes_highLat_SO simA (historical simulation): https://doi.org/10.26050/WDCC/FESOM14-REcoM2_A_hist_vA_vCsimA-ssp126: https://doi.org/10.26050/WDCC/FESOM14-REcoM2_A_s126_vA_vCsimA-ssp245: https://doi.org/10.26050/WDCC/FESOM14-REcoM2_A_s245_vA_vCsimA-ssp370: https://doi.org/10.26050/WDCC/FESOM14-REcoM2_A_s370_vA_vCsimA-ssp585: https://doi.org/10.26050/WDCC/FESOM14-REcoM2_A_s585_vA_vCsimB (control simulation): https://doi.org/10.26050/WDCC/FESOM14-REcoM2_B_1921_cA_cC The raw model output was first post-processed with MASTER_toothfish_postprocessing_AGI_save_netcdf_files_monthly_with_drift_correction.ipynb to get fields of in-situ temperature (t_insitu) and partial pressure of oxygen (pO2) on the regular grid used in this study (see Mesh_ancillary_information_v20220919.nc). Subsequently, these data are post-processed with reduce_depth_levels_drift_corr_files.sh. 2-dimensional distribution data of Antarctic Toothfish prey used in this study can be accessed viahttps://doi.org/10.5281/zenodo.10598488 The following files are provided here: Monthly climatological pO2 and t_insitu 1995-2014 (used to compute preferred temperature, pO2 threshold and critical AGI of each species):- pO2_fesom_simA_monthly_clim_1995_2014_v2.nc- t_insitu_fesom_simA_monthly_clim_1995_2014_v2.nc Annual pO2 and t_insitu for the historical period 1995-2014:- pO2_fesom_historical_1995_2014_annual_mean_AGImesh.tar.gz- t_insitu_historical_1995_2014_annual_mean_AGImesh.tar.gz Drift-corrected annual pO2 and t_insitu 2091-2100 for four emission scenarios: - pO2_fesom_ssp126_2091_2100_drift_corrected_annual_mean_AGImesh.tar.gz- pO2_fesom_ssp245_2091_2100_drift_corrected_annual_mean_AGImesh.tar.gz- pO2_fesom_ssp370_2091_2100_drift_corrected_annual_mean_AGImesh.tar.gz- pO2_fesom_ssp585_2091_2100_drift_corrected_annual_mean_AGImesh.tar.gz- t_insitu_fesom_ssp126_2091_2100_drift_corrected_annual_mean_AGImesh.tar.gz- t_insitu_fesom_ssp245_2091_2100_drift_corrected_annual_mean_AGImesh.tar.gz- t_insitu_fesom_ssp370_2091_2100_drift_corrected_annual_mean_AGImesh.tar.gz- t_insitu_fesom_ssp585_2091_2100_drift_corrected_annual_mean_AGImesh.tar.gz Sensitivity to chosen future time period / Drift-corrected annual pO2 and t_insitu 2081-2100 and 2098-2100 for the highest-emission scenario SSP5-8.5: - pO2_fesom_ssp585_2081_2100_drift_corrected_annual_mean_AGImesh.tar.gz- pO2_fesom_ssp585_2098_2100_drift_corrected_annual_mean_AGImesh.tar.gz- t_insitu_fesom_ssp585_2081_2100_drift_corrected_annual_mean_AGImesh.tar.gz- t_insitu_fesom_ssp585_2098_2100_drift_corrected_annual_mean_AGImesh.tar.gz Attributing change to warming and deoxygenation / Drift-corrected annual pO2 2091-2100 at clim. t_insitu for the highest-emission scenario SSP5-8.5:- pO2_fesom_ssp585_2091_2100_drift_corrected_at_clim_t_insitu_annual_mean_AGImesh.tar.gz Information on model drift (used to correct the above files): - oxygen_fesom_simB_1995_2014_2091_2100_monthly.tar.gz- pO2_fesom_simB_1995_2014_2091_2100_monthly.tar.gz- salinity_fesom_simB_1995_2014_2091_2100_monthly.tar.gz- t_insitu_fesom_simB_1995_2014_2091_2100_monthly.tar.gz
