1 SURFACE HYDRODYNAMIC CONDITIONS MONITORING IN THE SICILY CHANNEL BY MEANS OF HF RADAR MEASUREMENTS INFO: G. Ciraolo 1, A. Drago 2, F. Capodici 1, F. Raffa 3, S. Cosoli 4, C. Nasello 1, G. La Loggia 1, A. Maltese 1, G.B. Ferreri 1 (1)Department of Civil, Environmental, Aerospace, Materials Engineering (DICAM) – Università degli studi di Palermo, Viale delle Scienze, Ed. 8, Palermo, Italy, (2)Physical Oceanography Unit, University of Malta, Malta (3)CNR- Istituto per l'Ambiente Marino Costiero, Italy (4)OGS - Istituto Nazionale di Oceanografia e Geofisica Sperimentale, Trieste, Italy

2 What is CALYPSO Calypso is a 2 years project co-financed by the Operative programme Italy-Malta – axes II. The project ‘s main target is the monitoring of the surface currents to provide an useful tool against the oil spill pollution in the Malta channel

3 THE CALYPSO PARTNERS PARTNERS 1 UNIVERSITY OF MALTA (UOM) Physical Oceanography Unit IOI – Malta Operational Centre, (LEADER) 2TRANSPORT MALTA (TM) 3CIVIL PROTECTION DEPARTMENT (CPD) 4ARMED FORCES OF MALTA (AFM) 5ARPA Sicilia – Regional Agency Environmental Protection 6 Istituto per l ’ Ambiente Marino Costiero uos di Capo Granitola Consiglio Nazionale delle Ricerche (IAMC-CNR CAPO GRANITOLA) 7 UNIVERSITA ’ DEGLI STUDI DI PALERMO Polo Universitario di Trapani (UNIPA) (SICILIAN FOCAL POINT) 8UNIVERSITA ’ DI CATANIA (CUTGANA)

4 THE CALYPSO GOALS (1/3) To set up a permanent network of HF antennas to be used to monitor the surface currents (and waves in the malta channel) The network has 3 HF Antennas (2 in Malta e and 1 in Sicily) at 13.5 MHz

5 THE CALYPSO GOALS (2/3) To provide data to be combined with numerical models in order to: 1.Optimize the interventions in case of oil spill accidents or deliberate release of oil; 2.Improve the navigation safety ; 3.Improve search and rescue (SAR);

6 WHY this area has to be monitored Marine Traffic (AIS) (red= oil tankers)

7 Why CALYPSO in the Malta channel Oil spills in the period: spills

8 8 Favignana, conseguenze della marea nera The Favignana oil spill (January 2013)

9 How a HF system works MHz (HF) -40 W km spatial res. -Hourly scale (currents and waves )

10 The Pozzallo HF installation (August 2013)

11 combination of the 3 Antennas data

12 VALIDATION: DRIFTERS Very complex structure of the surface currents Giugno 2013 (con la collaborazione della CP) Settembre 2013 (con la collaborazione della Lega Navale – Pozzallo)

13 coverage until the 24° Aug. The Pozzallo HF system: validation

14 VALIDATION Accordo con i dati Calypso intorno a (0,8) Accordo dei dati ADCP con i dati Calypso intorno a (0,9)

15 BACKTRACKING e FORECASTING

16 CALYPSO 2: to extend the CALYPSO coverage 3 hypotheses for the next HF system position coverage until the 24° Aug. ScoglittiGelaLicata Future expansion of the System Advantages: redundancy increased coverage better quality of the maps

17 DREAMING A FULL HF COVERAGE FOR THE SICILIAN COAST coverage until the 24° Aug. Future expansion of the System

18 Meeting a Ragusa 21Novembre 2011 Conclusions The system management for the next 5 year will require a certain effort from economical point of view (and not only) An amount of 8-10 thousand € per year is required to maintain the Pozzallo system (frequency authorization, insurance, system maintenance, energy supply, internet connection) Periodic field survey would be needed to test the accuracy of the system An agreement on the use of the data by external customer is needed New funds have to be found to finance and expand the network INFO:
