HCMR Activities in the Red Sea C. Smith & Ε. Παπαθανασίου
HCMR in the Red Sea• The Hellenic Centre for Marine Research (HCMR) started activities in the Red Sea in March 2010.• This was the result of a framework agreement between, SETE Facilities Management Saudia Ltd (Latsis Group), to cover 3 major long term missions up to 2012-13 with KAUST University in Saudi Arabia with the Greek Oceanographic Vessel “Aegaeo”, in the Red Sea• This opened a great opportunity for cooperation at the scientific and political level,• Participation in a wide range of activities at the national, bilateral and international level, with Greece being one of the first countries to cooperate scientifically in this little explored area through common research interests.
Aims1. High resolution mapping of the seabed in the Red Sea,2. Characterisation of water masses,3. High level environmental study of deep brine lakes4. The search for deep corals in the Red Sea and their relationships with deep corals in the Eastern Mediterranean.5. Direct cooperation with scientists from KAUST university, also with the USA (Wood Hole Oceanographic Institute), China (Hong Kong University) and Egypt (American University of Cairo), also actively involved in scientific research in the area.HCMR Personnel: 18 research and technical staff were involved in 2010-11Utilising: Submarine ‘Thetis” and the robot vehicle “MAXROV”
TargetsMedium Term Targets and Directions:• 2010: Charter out the vessel for physical chemistry and biological studies• 2011: Research collaboration between HCMR and KAUST, Woods Hole and the University of Hong Kong (already have 3 publications and 1 in press)• 2013-14: Increasing cooperation with new agreements for more research at different levels in the area.
KAUST Red Sea Expedition 2010• 2010 Mission: 63 days.• Research in Saudi Arabian territorial waters, looking at many things for the first time• The research results are particularly important for world level publication.• New discovery: during HCMR MAXROV dives, we found a new brine lake at approximately 860 m depth.
KAUST Red Sea Expedition 2010• Leg - I (15th March – 1st April) – Mission Collection of biological and oceanographic data to study Red Sea hydrography and microbial diversity – Sampling locations 10 perpendicular transects along the Saudi coast of the Red Sea• Leg - II (6th – 17th April) – Mission Collection of water and plankton samples from different depth layers to study brine pool biota – Sampling locations Brine pool systems: Atlantis II Deep (AIID) and Discovery Deep (DD)• Leg - III (20th – 29th April) – Mission Collection of sediment and benthos samples to study brine pool biota and geology – Sampling locations 1 transect from Jeddah to AIID, 2 transects at AIID and 1 at DD
