The Misteriosa Bank is a submerged bank or atoll in the Caribbean Sea, located at – approximately equidistant from Mexico (), Honduras () and Cuba (). The bank is long and wide. The area is .〔()〕 Immediately south of it is Rosario Bank. The closest piece of land is the Swan Islands, Honduras, to the south and separated from it by the more than Cayman Trench. The reported depth is on the average () or up to , with depths of along the rim,〔()〕 or (). It is part of the Cayman Ridge.〔()()〕 A buoy has been anchored to the seabed of this submerged peak of a sea mountain range that appears to have been claimed by the Principality of New Utopia. The placing of the buoy was filmed by a German film crew and broadcast by Arte television on satellite. New Utopia maintains no state claims it, and wants to build a kind of micronation on top of it, using concrete blocks. ==Charles Darwin== Charles Darwin's ''Coral Reefs'' mentions the Misteriosa Bank as an example of the sharply declining coral reef: :"Besides the coast-banks, there are many of various dimensions which stand quite isolated; these closely resemble each other, they lie from two or three to twenty or thirty fathoms (to 55 m ) under water, and are composed of sand, sometimes firmly agglutinated, with little or no coral; their surfaces are smooth and nearly level, shelving only to the amount of a few fathoms, very gradually all round towards their edges, where they plunge abruptly into the unfathomable sea. This steep inclination of their sides, which is likewise characteristic of the coast-banks, is very remarkable: I may give as an instance, the Misteriosa Bank, on the edges of which the soundings change in 250 fathoms (m ) horizontal distance, from 11 to 210 fathoms (to 380 m )..." 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Misteriosa Bank」の詳細全文を読む スポンサード リンク
