As part of the Living on Water project, we are aiming to bring the underwater archaeology of crannogs to as wide an audience as possible. Normal terrestrial archaeological excavation has the benefit of being visible and accessible to most of the land-loving public through site visits and open days where non-archaeologists can get up close and see the archaeology as it happens. With underwater crannogs, this more difficult. However, there are ways we can make what is underwater, accessible only to those who SCUBA dive, accessible, and that is through digital recording techniques.
Photogrammetry has become a very powerful tool in the underwater archaeologists tool kit. It allows us to far more rapidly record underwater targets using photographs to create relatively accurate and precise 3D models. These models can then be used like traditional archaeological methods – to record and understand the archaeology.
So far we’ve been targeting specific elements of Oakbank crannog. These include areas we have sampled as part of our analysis of Oakbank’s chronology, but also a range of other interesting features.
Explore the photogrammetric models below. And please check back again, we’ll be uploading more models and updating these in due course with annotations and higher resolution models.
