Rosemary Bank Seamount
Nature Conservation Marine Protected Area
United Kingdom: Scotland
The Rosemary Bank Seamount NCMPA (Nature Conservation MPA) is located to the north-east of the Rockall Trough, in the deep waters off western Scotland. An extinct volcano, Rosemary Bank towers over 1000 metres above the seafloor and is one of three seamounts present in Scotland‟s seas.The seamount is a hotspot for sea life and significant to the health of Scotland‟s seas because of the way it influences underwater currents that bring valuable nutrients to the region, as well asproviding nursery and foraging areas for several types of fish.
Rising up from the surrounding flat seabed, the Rosemary Bank Seamount is an imposing extinct volcano that now provides a hard surface on which sea life abounds. The size and shape of the seamount influences underwater currents, which bring a plentiful supply of food to the area. The conditions enable the establishment of seamount communities, which include deep-sea sponge aggregations and cold water corals. Deep-water fish also live here; including orange roughy and blue ling. The migratory route of larger animals such as sperm and pilot whales passes the area, attracted by the high levels of productivity.
