MedGLOSS is a CIESM/IOC network for the real-time monitoring of sea level in the Mediterranean and Black Seas. The sea level station at Portomaso marina within the Malta Hilton is run and maintained by the Physical Oceanography Unit within the Faculty of Science of the University of Malta. The network is run in collaboration with the Israel Oceanographic & Limnological Research Ltd. The activity is co-ordinated by Prof. Aldo Drago, Head of the PO Unit (aldo.drago@um.edu.mt).

The Mediterranean regional subsystem of the Global Sea Level Observing System (MedGLOSS) is a real-time monitoring network for systematic measurements of the sea level in the Mediterranean and Black Seas. It follows GLOSS requirements and methodology, aiming to provide high-quality standardised sea level data. MedGLOSS is a joint initiative of UNESCO/IOC (Intergovernmental Oceanographic Commission) and CIESM (Commission for Marine Research in the Mediterranean) and contributes to study the worldwide eustatic sea-level rise due to the “greenhouse effect” as well as to provide the ellipsoid to geoid corrections in the sea-level real time satellite elevation measurements. The MedGLOSS network has already installations in Israel, Malta, Croatia, Cyprus, Bulgaria and Romania. The PO-Unit is responsible of the MedGLOSS node station in Malta. The installation of the sea level gauge was completed in February 2001 in the Portomaso marina at the Malta Hilton in St. Julians and constitutes the first real-time monitoring station for oceanographic data in Malta.

The instrument collects sea level data, sea water temperature, and atmospheric pressure. The system has been recently upgraded with new equipment to enable higher sampling rates, and to enable a first phase towards contributing to the tsunami detection system for the Mediterranean. The Malta MedGLOSS station will be contributing as one of the stations to detect anomalous sea level signals within the framework of the Mediterranean Tsunami Warning System. This activity is a contribution to NEAMTWS, the Tsunami Early Warning and Mitigation System in the North-Eastern Atlantic, the Mediterranean and Connected Seas.

Hourly averaged observations are shared in real-time with international networks. This activity is conducted in cooperation with the Israel Oceanographic and Limnological Research (IOLR) that leads the project. The data from the MedGLOSS station provides sea level information for climate change studies in the Maltese Islands. In combination with sea level data collected since 1993 by the PO-Unit in Mellieha Bay, studies have been conducted by Prof. Aldo Drago to assess local sea level trends. Recent reports have been submitted to Malta’s 2nd National Report to UNFCCC, and to the publication on Health Effects of Climate Change in the Maltese Islands.
