Heritage Malta

Heritage Malta

Malta’s incredibly rich and multi-variegated historical past is mirrored in the diversity of its underwater heritage. A subaquatic museum waiting to be discovered. Systematic undersea archaeological surveys off the coast of the Maltese Islands have revealed a multitude of underwater archaeological sites. These range from a 2,700 year-old Phoenician Shipwreck, Roman and Early Modern Shipwrecks to dozens of aircraft crash sites, submarines, and battleships from the First and Second World Wars. This underwater cultural heritage legacy has made Malta the curator for a uniquely well-preserved cultural resource that is global and belongs to all humankind. The recognition of responsibility towards properly managing and protecting Malta’s underwater cultural heritage resulted in the decision to create the Underwater Cultural Heritage Unit (UCHU) within Heritage Malta, the national agency for cultural heritage, conservations and museums. The main objectives of the UCHU are the identification and documentation of sites, site valorisation and protection, as well as public access management and public outreach. The UCHU aims to continue opening underwater sites for public access, whilst ensuring that the authenticity and integrity of Malta’s UCH is protected, in keeping with the UNESCO Convention on the Protection of the Underwater Cultural Heritage.

Outcomes in diving are a combination of technical skills, context, some luck, and Non-Technical Skills. Non-Technical Skills (decision-making, situation awareness, communication, leadership & followership, teamwork, and performance shaping factors) are rarely taught in formal diving courses. The Human Diver’s programmes are delivered via online, live webinar, and face-to-face, with instructors ranging from the West coast of the US to Australia. They are accessible to all and relevant to everyone. Apply Human Factors. Master the Dive.
