Radiocarbon DatingYou may like to watch the video mini-lecture on YouTube from the Rafter Radiocarbon Laboratory. Absolute dating, also referred to as chronometric dating, is the process of calculating an approximate calendric age. This contrasts with relative dating techniques, as these can only order a sequence of events. Absolute dates cannot produce a precise date when a particular event happened, but rather can offer a range of dates during which the event occurred. The most widely used technique is radiocarbon dating, also called C14 dating.

Measuring the FindsMeasuring the Finds follows Martin Read in his work between 2003 and 2005 on the Tudor warship the Mary Rose, sunk in the Solent Portsmouth in 1545. Martin lecturers in Maritime Archaeology and Computing and has extensive knowledge of Maritime Archaeology and Finds Processing.
Martin has worked on a number of internationally important archaeological shipwreck projects, including several VOC shipwrecks and the Tudor Cattewater shipwreck. The video gives an insight into finds handling that is often overlooked in the headlines, but is undoubtably the most important part of any archaeological project. |

Effective 4 point mooring system
This short film is an example of an effective 4 point mooring system that can be set up for use on archaeological sites. It has the advantage whereby the anchor cables are clear of the site itself and allow the DSV above to move and be repositioned over different parts of the site without dragging through the site and causing damage to archaeological material exposed on the seabed. It also allows the DSV to quickly disconnect and to later reconnect for example for leaving the site for bad weather or for a port visit.
