Abstract
The continental shelf around Scotland covers an area of ~286,500 km2, around 3.5 times the size of the Scottish landmass. This relatively shallow underwater realm (mainly 100 m lower than at present, and more recent marine processes, active since sea levels rose. This chapter outlines the main geomorphological landsystems found on the shelf, highlighting notable landform examples imaged in high-resolution digital bathymetry data. Many of the landforms have remained exceptionally well preserved since deglaciation, unlike on land, having not been subject to significant disturbance by human activity. The uniquely preserved submarine landforms and landscapes in the shallow seas around Scotland should be protected where possible, especially where they host rare or valuable ecosystems.
