This open access peer-reviewed volume was inspired by the UNESCO UNITWIN Network for Underwater Archaeology International Workshop held at Flinders University, Adelaide, Australia in November 2016. Content is based on, but not limited to, the work presented at the workshop which was dedicated to 3D recording and interpretation for maritime archaeology. The volume consists of contributions from leading international experts as well as up-and-coming early career researchers from around the globe. The content of the book includes recording and analysis of maritime archaeology through emerging technologies, including both practical and theoretical contributions. Topics include photogrammetric recording, laser scanning, marine geophysical 3D survey techniques, virtual reality, 3D modelling and reconstruction, data integration and Geographic Information Systems. The principal incentive for this publication is the ongoing rapid shift in the methodologies of maritime archaeology within recent years and a marked increase in the use of 3D and digital approaches. This convergence of digital technologies such as underwater photography and photogrammetry, 3D sonar, 3D virtual reality, and 3D printing has highlighted a pressing need for these new methodologies to be considered together, both in terms of defining the state-of-the-art and for consideration of future directions. As a scholarly publication, the audience for the book includes students and researchers, as well as professionals working in various aspects of archaeology, heritage management, education, museums, and public policy. It will be of special interest to those working in the field of coastal cultural resource management and underwater archaeology but will also be of broader interest to anyone interested in archaeology and to those in other disciplines who are now engaging with 3D recording and visualization.

Excerpt from Instructions as to the Tonnage Measurement of Ships 1. Authority for instructions. - These instructions are issued by the Board of Trade under the provisions of the Merchant Shipping Acts for the assistance and guidance of their officers in measuring the tonnage of ships. 2. Fees and expenses. - Instructions as to the fees and expenses payable in connection with tonnage measurement are contained in the pamphlet entitled " List of fees and expenses payable in connection with Board of Trade surveys."* 3. Law relating to tonnage. - The tonnage regulations of the Merchant Shipping Acts, 1894 to 1907, are inserted in Appendix 1, page 61, and the Surveyors are expected to make themselves thoroughly conversant therewith, and also with the following instructions regarding their application. Whenever in the course of these instructions reference is made to "the Act" or to a section or schedule by number only, the reference is to the Merchant Shipping Act, 1894. 4. Surveyors to refer to Principal Surveyor for Tonnage. - The Measuring Surveyor will in all cases obey and be immediately responsible to the Principal Surveyor for Tonnage with regard to these instructions, and when in doubt upon any point, he should refer it to him for direction, and the Principal Surveyor will, if necessary, submit it for the consideration and decision of the Board of Trade. 5. Gross and net tonnage. - For the purpose of the tonnage regulations of the Merchant Shipping Acts, the ton is a unit of volume containing 100 cubic feet. The Act provides that, for the purpose of ascertaining the register or net tonnage of a ship, the gross tonnage shall first be ascertained in accordance with the directions contained in the second schedule, and the deductions provided for in the Acts shall then be made from the gross tonnage so ascertained.

Excerpt from Shipbuilding and Shipping Record, Vol. 11: March 28, 1918 This discussion on local failure brings up the question of secondary bracing. Certain girders and stringers require brackets in order to prevent collapse from oblique loading it is not an easy matter for-any form of calculation, but a close study of actual experience should produce rules for general guidance. Construction of double bottom - Even the most enlightened naval architects appear 'to have only hazy ideas concerning the structural work performed by the complicated double bottom, which is now a common feature in merchant ships. The more general practice is to dispose the internal framing in the transverse direction, retain ing a very small amount of longitudinal material mainly for local support. These longitudinal intercostal members also fulfil some function as secondary bracing, but the nature of the work performed is very obscure. It is, of course, true that facility of erection has favoured transverse framing but here, again, if economy of weight is required, Search must be made for a distribution which is more in the longitudinal sense than the present practice. Some well known efforts have already been made towards this aim, but the final solution has yet to be sought.
