3D MAPPING OF A MARINE CAVE, THE IMPORTANCE OF ESTABLISHING A BASELINE
Although marine caves are only a small fraction of Mediterranean marine environments, they are considered biodiversity hotspots, acting as a reservoir for many endemic species, especially sponges.
The rise of new technologies, as Structure from Motion (SfM) photogrammetry, gives now the opportunity to obtain a detailed three-dimensional (3D) digital reconstruction from a series of overlapping images. In this context, this 3D model was produced to investigate the application of this technique to assess the sponge assemblages inside an Italian cave, obtaining a useful baseline to document possible shifts in the community composition due to climate warming and anthropic exploitation.
