Marine Archaeology

The basic purpose of archaeology is to collect data which, after analysis and interpretation can contribute to the explanation and understanding of the past.

It is not just a matter of collecting and describing artefacts, but an attempt to go beyond the external features of beauty and curiosity, to find the message and communicative ingredients of the archaeological remains. To achieve this goal the choice of methods and techniques is important. In 1981 Kalmar Läns Museum began marine archaeological investigations on Kronan. Test trenches were excavated, in order to determine the volume and spread of objects and ships' structure. In the spring of 1983, a grid co-ordinate system was constructed over the site. The co-ordinate system is the basis for mapping the site and plotting objects during investigation. A 50 x 40 m rectangle was established, framing the wreck area. This rectangular area was then divided into twenty 10 x 10 m squares. Immediately after, a photographic survey was carried out in order to create a photomosaic of the site. Black & white and colour still photography in conjunction with video-cameras, are used continuously during diving operations to obtain as much information as possible. Also, a stationary black and white camera acts as a safeguard for the divers by constantly monitoring the excavations. Below: Archaeological site plan of the Kronan wrecksite. The missing bow sections are marked with a dashed line. Areas excavated or partially excavated are surrounded by a solid line; this accounts for more than 80% of the wrecks total area. The circle encompasses the excavated area during 2005-2007 seasons.
