Internet users can explore the world's largest coral reef as part of a new research project, the Catlin Seaview Survey , a joint venture between Google, the University of Queensland and the Catlin Group. Tens of thousands of 360-degree, high-definition panoramas of underwater forests, grasslands and crags will be taken by robot cameras, mapped and made available on the internet as a result of the collaboration, which will seek help from a global audience to assess the health and composition of the 2,300km-long reef
