Alchemy or Science? Compromising Archaeology in the Deep Sea

In the torrid debate between archaeology and treasure hunting, compromise is often suggested as the pragmatic solution, especially for archaeology carried out either in deep water or beyond the constraints that commonly regulate such activities in territorial seas. Both the wisdom and the need for such compromise have even been advocated by some archaeologists, particularly in forums such as the internet and conferences. This paper argues that such a compromise is impossible, not in order to fuel confrontation but simply because of the nature of any academic discipline. We can define what archaeology is in terms of its aims, theories, methods and ethics, so combining it with an activity founded on opposing principles must transform it into something else. The way forward for archaeology in the deep sea does not lie in a contradictory realignment of archaeology’s goals but in collaborative research designed to mesh with emerging national and regional research and management plans.     

The Managerial Equation and Innovation Platforms: The Case of Linköping and Berzelius Science Park

This paper explores the political and economic origins of a science park in Linköping, Sweden. It shows how different “innovation platforms” emerged to develop the medical industrial sector. An innovation platform is a foundation for growth corresponding to a given set of organizations or networks that incubate and sustain innovative teams tied to a given sector. Large firms and incubator-linked science parks represent different kinds of innovative platforms. The paper centres on the concept of the “managerial equation”, arguing that growth projects like science parks build on coalitions and networks linking innovative resources, acquired knowledge tied to a given sector and power linked to decision-making power and financial resources. Changes within these elements of the equation explain the rise and fall of innovative platforms. Failures in learning in one platform lead to the rise of another. An absence of power (such as supporting resources) can also account for platform changes. Regional development decisions do not simply reflect path dependent specializations as regions use related capacities to break into “new” sectors. Commitments to Triple Helix formations linking universities, corporations and the government reflect changes within each branch of the Helix and political decision-making creating a diversity of development pathways.     

Multi-image Photogrammetry for Underwater Archaeological Site Recording: An Accessible,Diver-Based Approach

This article presents a discussion of recent advances in underwater photogrammetric survey, illustrated by case studies in Scotland and Denmark between 2011 and 2013. Results from field trials are discussed with the aim of illustrating practical low-cost solutions for recording underwater archaeological sites in 3D using photogrammetry and using this data to offer enhanced recording, interpretation and analysis. We argue that the availability of integrated multi-image photogrammetry software, highly light-sensitive digital sensors and wide-aperture compact cameras, now allow for simple work flows with minimal equipment and excellent natural colour images even at depths of up to 30 m. This has changed the possibilities for underwater photogrammetric recording, which can now be done on a small scale, through the use of a single camera and automated work flow. The intention of this paper is to demonstrate the quality and versatility of the ‘one camera/ambient light/integrated software’ technique through the case studies presented and the results derived from this process. We also demonstrate how the 3D data generated can be subjected to surface analysis techniques to enhance detail and to generate data-driven fly-throughs and reconstructions, opening the door to new avenues of engagement with both specialists and the wider public.
