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

Basic information

Model Version: osmose 3.0

Simulation Round Specific Description: * Data in embargo period: not yet publicly available, but currently only shared among the ISIMIP participants.

Resolution

Spatial aggregation: regular grid

Temporal resolution of input data: climate variables: monthly

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

Spin-up

Was a spin-up performed?: No

Spin-up design: simulations started in 1992

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.

Defining features: fisheries for all comercial species included, mainly dominated by anchovy fisheries

Spatial scale: 1/6º degree, 15 days time step

Taxonomic scope: 8 species + 1 functional group explicitly modeled

Vertical resolution: no

Spatial dispersal included: yes

Is fishbase used for mass-length conversion?: no
