In addition it can be difficult to allow access to the results of the archaeological research as underwater sites do not provide good outreach possibilities or access for the general public.[23] Work has been done to bridge this difficulty through the use of the World Wide Web for webcasting projects, or dedicated virtual reality systems [24] that allow users to perform a virtual diving into an interactive 3D reconstruction of the underwater archaeological site. An example is the excavation of the Queen Anne's Revenge[25] and the QAR DiveLive program,[26] a live interactive virtual field trip to the wrecksite.
