Model outputs and code used for the study "Global nutrient cycling by commercially targeted marine fish" published in Biogeosciences (Le Mézo et al., 2022). 

• composite4b_cycling_MCV3_PotH_LME_2010_R2_2010_fNPP7_ks24_p50_c7_newFNPP_Online_nruns_31 = model outputs with
  • composite.maps contains the 2D fields
  • y200 refers to fields at the pristine state and yglo to fields at the global peak catch.
  • dfish is the fish biomass in wet weight per gram (size class)
  • resp5 is the cycling rate that was used in the paper (defined in the Methods section)
• Main_script.mlx = main code used to compute the nutrient content and cycling of fish and the comparisons with other fields
• size_bins_width.m = code used to compute the model size bin width
• data_annual.mat = NO3, PO4, NPP, C export fields
• composite_MCV3_PotH_LME_2010_R2_2010_fNPP7_ks24_p50_c7_newFNPP_Online_nruns_31.mat is the model outputs with
