MEDSLIK-II general description The oil spill model code MEDSLIK-II, based on its precursor oil spill model MEDSLIK
is a freely available community model
#2
MEDSLIK-II uses a Lagrangian representation of the oil slick
MEDSLIK-II predicts the transport and oil transformation processes due to complex physical and chemical processes occurring in the sea-water interface
MEDSLIK-II includes a proper representation of high frequency currents, the wave induced currents and wind fields in the advective components of the Lagrangian trajectory model

MEDSLIK-II as a full physics model
Advection-diffusion part is solved using a Lagrangian approach taking into account Eulerian currents Wave induced currents Wind correction Turbulence
Trasformation processes are solved considering the entire oil slick volume, subdivided in a thick and thick part. The oil fuxes due to evaporation, dispersion and spreading processes:
The model solves the advection-diffusion-transformation equation:

MONGOOS and REMPEC
• Cooperation between the Mediterranean Operational Oceanography Network-MOON now MONGOOS and REMPEC in the field of oil spill combating
• MONGOOS partners and REMPEC signed the MOON-REMPEC agreement for cooperation and MOON established the Emergency Response Office-ERO to Support REMPEC in the management of oil spill emergency in the Mediterranean Sea
• In the past years, ERO experts provided REMEPEC and national authorities with support in several occasions

Pollution Hazard Mapping (PHM) as a new AFS/MEDSLIK-II service
“Hazard refers to the likelihood frequency (expressed as a probability) of any particular area to be affected by a destructive event within a given period of time”
(UNESCO, 1972)
The PHM subject is Operational Hazard from the Ship Traffic
Operational Oil Pollution: • Ballast Waters • Tank Washings • Engine Room Effluent Discharges
(Pavlakis et al., 2001)
The area of interest is the Southern Adriatic and Northern Ionian Sea (SANI)

Generalization of the problem
Specify the source of the oil spill hazard: - Ship/tanker traffic, - Platform and rigs, - Pipelines, etc - Any random set of potential sources
Run MEDSLIK-II stochastic scenarios on high-precision AFS and ECWMF archives
Obtain PHM for sea surface and shoreline
Use the information for planning the coastal facilities and improvement of the counter-measures in case of accidents
