Impact model: OSMOSE (N Humboldt)

Northern Humboldt model for main pelagic species, interannual variability estimated for key parameters, 1992-2008 hindcast period. OSMOSE (Northern Humboldt) is one of the 9 regional models following the ISIMIP2a protocol which form the base of simulations for the ISIMIP2a regional fisheries & marine ecosystems sector outputs; for a full technical description of the ISIMIP2a Simulation Data from Fisheries & Marine Ecosystems (Fish-MIP; regional) Sector, see this DOI link: http://doi.org/10.5880/PIK.2018.004

Exceptions to Protocol
Exceptions: downscaling of the plankton biomass, nearest-neighbor approach not used, biological effects were fixed to the climatology not to 2005 values

Management & Adaptation Measures
Management: fishing constant in 2005 levels
Extreme Events & Disturbances
Key Challenges: We estimated time series for larval mortality , a key parameter for the model, in order to reproduce the impact of ENSO in the population dynamics.
