Over the past couple of years we have been collecting bathymetry and sub-bottom seismic information from the Bay of Firth and Loch of Stenness. These give us the first hint at palaeo-landscapes.

The results allow us to target areas of the seafloor that are rock and those of sediment. The rock areas are investigated by ROV (remotely operated vehicle) or diver and the sediment by coring
