IKUWA - Internationaler Kongress für Unterwasserarchäologie - is a global network of cooperating bodies that organises congresses focused on underwater archaeology to raise awareness of the importance of underwater cultural heritage and to create an international regulatory framework for its protection.
IKUWA - the first International Congress for Underwater Archaeology - was held in February 1999 in Sassnitz, Germany, with the theme "protection of cultural heritage under water". IKUWA2 was held in Zurich in October 2004. IKUWA3 was held in London in 2008. The Congress saw the Nautical Archaeology Society (NAS) in conjunction with project partners, the Institute of Field Archaeologists, and the Institute of Archaeology, University College London, playing host to the largest conference on underwater archaeology ever held. IKUWA4 was held in October 2011 in Zadar, Croatia, where the International Centre for Underwater Archaeology has been established under UNESCO's auspices. The theme of IKUWA4 was "Managing the underwater cultural heritage". IKUWA5 was held in October 2014 in Cartagena, Spain, at the Universidad Politecnica de Cartagena. The event was organised by the National Museum of Underwater Archaeology and hosted by the Spanish Ministry of Culture. The theme of IKUWA 5 was "Heritage for Humanity".
