The threats to underwater cultural heritage are multiple. The coasts, oceans and seabed are increasingly exploited and used for economic activities. One of the enduring international challenges in maritime archaeology has been keeping dialogue open between 'amateur' divers and historians, and professional researchers, conservators, archaeologists and historians. Moreover, ensuring that such partnerships between interested citizens, government departments and academia stay in place requires a long-term commitment to sharing the results of maritime archaeology projects. Some of the challenges are communication and historical integration aspect of projects. Finding a rich and valuable template for integrating historical, archaeological and heritage management material in a thorough and engaging format is the future challenge that must be handled.
