title: Model output for analyses conducted in de la Vega & Buchanan et al. (2022) Global Change Biology

description: Model data for: De La Vega & Buchanan et al. (2022) Multi-decadal environmental change in the<br> Barents Sea recorded by seal teeth. Global Change Biology. Each netcdf file (.nc) contains model output from simulations performed with the<br> NEMO-SI3-PISCES global ocean-seaice-biogeochemistry model. These simulations were<br> forced by the Japanese Atmospheric Reanalysis 55 (Tsujino et al. 2018), which<br> provides "best-guess" atmospheric conditions since 1958 to present day. Simulations<br> for this study were performed from Jan 1958 - Dec 2019. Variables included here are:<br> - zonal velocity (u) m s-1<br> - meridional velocity (v) m s-1<br> - potential temperature (thetao) degrees C<br> - salinity (so) psu<br> - sea ice concentraton (siconc) 0-1<br> - nitrate (NO3) mmol m-3<br> - nitrate 15 (NO3_15) mmol m-3<br> - small particulate organics (POC) mmol m-3<br> - small particulate organics 15 (POC_15) mmol m-3<br> - large particulate organics (GOC) mmol m-3<br> - large particulate organics 15 (GOC_15) mmol m-3<br> - nanophytoplankton NPP (PPPHYN) mol C m-3 s-1<br> - diatoms NPP (PPPHYD) mol C m-3 s-1<br> - nanophytoplankton chlorophyll (NCHL) mmol m-3<br> - diatoms chlorophyll (DCHL) mmol m-3<br> - atmospheric N deposition (NDEP) kg N m-2 s-1 <br> Files:<br> ETOPO_JRA55_pic_1y_u_1958-2019.nc<br> ETOPO_JRA55_pic_1y_v_1958-2019.nc<br> ETOPO_JRA55_pic_1y_TS_1958-2019.nc<br> ETOPO_JRA55_pic_1y_ice_1958-2019.nc<br> ETOPO_JRA55_pic_1y_isos_1958-2019.nc<br> ETOPO_JRA55_pic_1y_npp_1958-2019.nc<br> ETOPO_JRA55_pic_1y_chl_1958-2019.nc<br> ETOPO_JRA55_ndep_1y_isos_1958-2019.nc<br> ETOPO_JRA55_ndep_1y_npp_1958-2019.nc<br> ETOPO_JRA55_ndep_1y_chl_1958-2019.nc<br> ETOPO_ndep_files_1801-2100.nc --&gt; Atmospheric deposition Naming convention:<br> "ETOPO" refers to being on a regular 1x1 degree horizontal grid<br> "JRA55" refers to forcing by the Japanese atmospheric reanalysis<br> "pic" refers to an experiment WITHOUT the historical increase in<br> atmospheric nitrogne deposition "ndep" refers to an experiment WITH the historical increase in<br> atmospheric nitrogne deposition<br> "1y" refers to the timestep resolution, here all 1 year.
