Coastal Monitoring HF radar DARDANOS

The Dardanos system is a High Frequency (HF) radar, transmitting low-power radio short waves and monitoring the sea-surface circulation east of the island of Lemnos, aiming to contribute to the assessment of the impact of the Black-Sea outflow on the North Aegean Sea. The system is jointly owned and managed by the Department of Marine Sciences of the University of the Aegean and the Institute of Oceanography of the Hellenic Centre for Marine Research. It produces maps of sea-surface circulation every 30 minutes. The most recent map can be accessed here.

Gulf of Kalloni Oceanographic mooring

ΑΤΤΕΝΤΙΟΝ: The Oceanographic Mooring is currently inactive, as it undergoes maintenance. Its redeployment is estimated to take place by the end of November 2025. Whatever values are presented on the related pages correspond to experimental measurements in the Laboratory Tank.

The mooring,  funded in the framework of the Coastal Environmental Observatory AEGIS, is equipped with a full array of meteorological and oceanographic sensors. It was deployed on the 28th of January 2020, at the center of the the Gulf, at position
