1. Exchanging Numerical Coastal Modelling Experiences
Introduction to MedGOOS Seminar
Exchanging Numerical Coastal Modelling Experiences
for Applications in the Mediterranean Region

2. GOOS: open sea vs coastal component
The “climate” component of GOOS has been, up to now, the main priority & focus of joint collaborative efforts
Significant progress have been made: observing system more than 80% developed; global/regional forecasting systems in place
Coastal component less developed; mainly based on national – uncoordinated programs
Challenges of Coastal areas:
Complex phenomenology (river runoff, coastal-open coupling, sediment dynamics etc)
Variety of scales (temporal, spatial)
Increased observing and modeling requirements (parameters, processes)

4. Mediterranean Sea approach
Downscaling / nesting : basin scale - subregional (3 km) - shelf models
Shelf models at 1.5 km
Sub-regional models at 3 km

5. Applications examples
Currents forecast: support of sailing games
Sediments transport
Pollutants transport; sewage outflow
Ecosystem status & integrated management
Oil drift forecast: response to accidents
Ecosystem modeling in oligotrophic areas

7. Remarks A possible model for future meetings
Further development of coastal modeling / systems: a priority for GOOS and the Mediterranean
MedGOOS seminar: an opportunity for scientific update and networking for future activities
A preparation for Al-Bahri
Several topics covered:
Relocatable models
Coupling of hydrodynamics – water quality – ecology
Downscaling
Modeling of lagoons
Modeling of organic mater production
A possible model for future meetings
