The Oilspill pilot MaaS and their main input and output data are summarized in following table. In addition to these data, user input parameters are needed to execute the MaaS.
Ps1 PredictOilDrift
Modelling the spilt oil's fate and behaviour consists of modelling changes in the oil's physical and chemical properties as it undergoes natural processes at sea (so-called weathering -- evaporation, dispersion, etc) and also modelling transport mechanisms (advection, turbulence).
Input data include user input data on the spill (In1), wind and currents forecasts (In2; In3), sea depth data (In4), coast line data (In5).
The main output is a 3D grid time series (= 4D) of oil concentrations in the water column, and a 2D time series of the oil slick position. Also, a mass balance time series (how much is evaporated, how much is stranded, etc) is provided.
Ps2 PredictCodEffects
The uptake of oil components by cod eggs and larvae is modelled by modelling the organisms' exposure to the oil concentrations in the water column based on the uptake rate per component.
Toxicity is modelled by calculating critical body residue (CBR) per component and totally, and lethality is derived from that.
The main input data are key species data for cod (individual weight; fat content) and population data for cod (spawning areas). The output is a 2D time series of cod lethality rates.
