MMT Supports Marine Archaeological Surveys

MMT has participated in the investigation on the 530 year old wreck Gribshunden outside Ronneby, Sweden.

MMT and MARIS (the Maritime Archaeological Research Institute) at Södertörn University have evaluated different techniques to map archaeological remains. The wreck Gribshunden has been one of the projects among others such as wreck investigations in the Baltic Sea on Mars, Lost Landscapes and Traveling Man.

MMTs former survey vessel Triad mapped the wreck site of Gribshunden with multibeam echo sounders and used a Blue View 3d sonar scanner on a stand next to the wreckage. According to the company, photographic material is now gathered in order to build photogrammetry of the wreck site and the data will be processed by MMT to create an accurate and high resolution image of the wreck site.

The commercial version of this kind of survey, using the still imagery for photogrammetry, is introduced with the new Survey ROV,  Surveyor Interceptor (SROV).

All data collected on Gribshunden will serve as a foundation for planning future excavations.

This year, the research vessel Svanen was used. This is a 10m long catamaran, equipped with the mapping technology and expertise from MMT, and the vessel is financed by the main owner of MMT (Carl Douglas) in order to support coastal archeology and technology development.

The regional museums Blekinge museum and Kalmar läns museum are local partners in the Gribshunden excavations.
