Impact model: DBEM

DBEM is one of the 6 global models following the ISIMIP2a protocol which form the base of simulations for the ISIMIP2a global fisheries & marine ecosystems sector outputs; for a full technical description of the ISIMIP2a Simulation Data from Fisheries & Marine Ecosystems (Fish-MIP; global) Sector, see this DOI link: http://doi.org/10.5880/PIK.2018.005

Resolution

Spatial aggregation: regular grid

Horizontal resolution: 0.5°x0.5°

Vertically resolved: Yes

Number of vertical layers: There are two layers, surface and bottom

Temporal resolution of input data: climate variables: annual

Temporal resolution of input data: co2: annual

Input data

Observed atmospheric climate data sets used: GFDL-MOM6-COBALT2 (ocean)

Emissions data sets used: Atmospheric composition (ISIMIP3a)

Other human influences data sets used: Fishing effort

Additional input data sets: The Sea Around Us CMSY data available at thesearoundus.org

Spin-up

Was a spin-up performed?: Yes

Spin-up design: Spin-up and transition period (1841-1960). Nominal spin-up (1841-1860, fishing held constant at 1861 levels) and pre-industrial transition period (1861-1960, reconstructed fishing effort). To set-up climate-forcing variables for the entire 1841-1960 period, we used the “control run” (ctrlclim) monthly output for the years 1961-1980 (inclusive) on repeat for six cycles.
