Pobie Bank

Pobie Bank lies beneath the North Sea east of the Shetland Islands, separated from their shores by the deeper Unst Basin. The long submerged bank consists of sedimentary and metamorphic rock, with patches of sand and gravel across its surface. Rugged outcrops rise from the seabed, providing places for sponges, corals and other marine life to grow. Though hidden below the waves, the bank is a distinct feature of the waters extending eastward from Shetland.
