HELLENIC CENTRE FOR MARINE RESEARCH - HELLENIC RESCUE TEAM COMBINED OPERATION

On Thursday, September 26, 2019, a combined operation between the Institute of Oceanography of the Hellenic Centre for Marine Research (HCMR) and the Hellenic Rescue Team (HRT) was carried out, deploying a scientific device in the Cretan Sea, approximately 25 nautical miles North from Herakleion, Crete. The rescue boat “Europe” carried out the operation with a crew of Mr. Vangelis Zacharioudakis (commander – chief of the Wet Search and Rescue), Dimitris Katranitsis (diver – rescuer), Manolis Zervos (navigator), Marios Trigonis (rescuer) and from HCMR, Mr. Nektarios Spyridakis

The objective of the combined operation was the deployment of  submersible scientific device ProVal that autonomously measures incoming and outgoing visible spectrum light of the ocean’s surface layer (0 – 100 m), using multisperspectral radiometers. These measurements are taken during the overpass of Ocean Colour satellites to help in their calibration. This demonstration experiment is part of a larger European initiative to confirm that the Cretan Sea is the best location in European waters and one of the best locations in the world, to host a large permanent moored buoy for Copernicus Ocean Colour satellite calibration. This is a pan-European collaboration involving HCMR, the Laboratoire Oceanographique of Villefranche (who developed the device deployed), ACRI-ST & ACRI-IN of France, the National Physical Laboratory of the UK, Tartu Observatory of Estonia, and the space agencies EUMETSAT and ESA. For Greece this is being directed by Dr. Stella Psarra, Dr. Andrew Banks, Dr. George Petihakis and Dr. Aris Karageorgis of HCMR.

The HRT contribution was decisive in the success of the deployment, due to the experienced and highly trained crew, as well as the rescue boat “Europe” itself. This is a high standard vessel with a large cargo capacity (compared to the draft of the vessel) a good working space and excellent safety during transit and during the deployment of the device.

The cooperation between HCMR and HRT will continue in the future, in similar combined operations in the Cretan Sea. Due to the transparency of the waters and the good weather around the year, this area is becoming of great interest to the Earth Observation scientific community. The next of these combined operations will involve the deployment of more measuring devices that aim to study the temperature interaction between the sea surface and the underlying near surface layer and how this influences the sea surface temperature as seen by satellite sensors.
