Rosemary Bank
Rosemary Bank is a seamount approximately west of Scotland, located in the Rockall Trough, in the northeast Atlantic. It was discovered in 1930 by the survey vessel HMS ''Rosemary'', from which it takes its name. It is one of only three seamounts known in Scottish waters. Rosemary Bank hosts a range of important habitats including deep sea sponge aggregations and cold water coral. Many species of fish, including orange roughy, blue ling, leafscale gulper shark The leafscale gulper shark (''Centrophorus squamosus'') is a dogfish of the family Centrophoridae. ''C. squamosus'' is reported to have a lifespan of approximately 70 years, based on otolith ring counts. It was the first described species in ... and Portuguese dogfish are also found here. In 2014 the bank was declared a Nature Conservation Marine Protected Area (NCMPA) in order to protect the sponge aggregations, and the cenozoic marine geomorphology of the seabed. The designation was withdrawn in 2020, when ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Seamount
A seamount is a large geologic landform that rises from the ocean floor that does not reach to the water's surface (sea level), and thus is not an island, islet or cliff-rock. Seamounts are typically formed from extinct volcanoes that rise abruptly and are usually found rising from the seafloor to in height. They are defined by oceanographers as independent features that rise to at least above the seafloor, characteristically of conical form.IHO, 2008. Standardization of Undersea Feature Names: Guidelines Proposal form Terminology, 4th ed. International Hydrographic Organization and Intergovernmental Oceanographic Commission, Monaco. The peaks are often found hundreds to thousands of meters below the surface, and are therefore considered to be within the deep sea. During their evolution over geologic time, the largest seamounts may reach the sea surface where wave action erodes the summit to form a flat surface. After they have subsided and sunk below the sea surface such flat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
