Underwater Mesolithic Site BC-II - June 2021

3D Model

Bouldnor Cliff on the north-west coast of the Isle of Wight is a series of sites dated to c. 8,100 BP that form part of a well preserved Mesolithic landscape and which represent the only confirmed submerged Mesolithic site in the UK.

Bouldnor Cliff Site II (BC-II) consists of peat developed over a sand bar deposit and is characterised by thousands of pieces of worked flints and debitage, as well as some faunal remains including wild boar and auroch.

This survey was captured in one dive in early June 2021. A photogrammetric model was developed in Agisoft Metashape from 1,777 images aquired using two Nikon D850 cameras with Orcalight Seawolf 2860 lighting in 40 minutes underwater. The resulting model was post-processed in ZBrush and Blender.

The length of the tape is 22.3m and the black/yellow scale bar is 1m. The average site depth was 11m.
