ACRG at field-school in Estonia

Ten days ago three members of ACRG visited Estonia to participate at the archaeological field-school. It was organised by Marge Konsa from University of Tartu who also spent several months in Southampton as a visiting research student. Field-school took place in Lihula, a tiny village in West Estonia. County of Läänemaa is filled with great archaeology, so we could enjoy little of it as well. Continue reading →

Underwater RTI HMS Invincible

On February 19th,  1758 the HMS Invincible set sail out of Portsmouth Harbor for Canada to join the British fleet to fight the French.  Unfortunately, due to a domino effect of extraordinary bad luck, she ran aground on Horse Tail Sand not far from the harbor.  Invincible was a French ship launched in 1744 and captured by the British in 1747.  At that time the British out-number the French on the sea.

Underwater Reflectance Transformation Imaging…a success.

I’ve been working on Reflectance Transformation Image capture in a sub-aquatic environment.  On 2 May, 2013 the first ever PTM file from an RTI dataset captured entirely underwater was successfully processed in the Archaeological Computing Research Group computer lab at the University of Southampton using RTIBuilder software.   Images were captured in 1.5 meters of water at the campus Jubilee pool using a common 12mpix digital camera and a 15 watt 1000 lumen HID dive-light.

James went back in September of 2012 for a second time to do more recording. Recently Dinah Eastop, a Curatorial Research Fellow from the National Archives has written two blog posts and presented the results of the work on their blog. Continue reading →
