N2  - The study was designed to identify the connection between features on the satellite image and the sea floor in Lonsdale Bight, Victoria, Australia, and to produce a map based on the findings. It used a semi-submersible vessel with an observation pod that can be lowered 1 m below the sea surface; this provides a stable platform from which spatially accurate data can be collected in the sub-marine environment, free from atmospheric effects. The results indicated a link between the depth and composition of the seabed and the spectral values found in the associated satellite image. Hence, the semi-submersible vessel is an ideal tool for seafloor imaging in shallow waters, without the disadvantages associated with diving.
