This chapter examines the benefits and constraints of collaboration between an archaeological research unit and a commercial company, using as examples joint research conducted by MARIS (Maritime Archaeological Research Institute at Södertörn University) and the Swedish commercial marine survey company MMT. The examples presented here included the detailed reconstruction by remote sensing of deeply submerged shipwrecks and the mapping and discovery of submerged archaeological landscapes and associated artefacts such as fish traps, which can then be examined more closely by archaeological divers. The benefits to archaeologists of collaborating with well-equipped commercial companies are obvious, but the benefits are mutual. The demands of archaeological research can generate new technological solutions that have commercial application, as well as producing results with wider educational and social benefits. Provided that archaeological investigations are embedded in the normal commercial operations of the company, such collaboration can be cost-effective for both parties, and is further enhanced by collaboration with film companies, which generates wider public interest and publicity for all concerned.

In trying to understand why archaeology is so strongly associated with the method of excavation, this paper examines different relationships between excavation, archaeology, archaeologists and modern society.
