Schmieder Bank
Schmieder Bank is a rocky undersea Bank (sea floor), bank west of Point Sur State Historic Park, Point Sur, California, roughly south of Monterey, supporting an extraordinarily lush Community (ecology), biological community, including very large individual colonies of the California hydrocoral, ''Stylaster californicus''. The bank lies about west-southwest offshore from Point Sur. Within the 75-meter contour, the bank is roughly elliptical, with its major axis running northwest–southeast, enclosing an area of about . The surface of the bank is a surf-erosional plateau, punctuated by a series of narrow ridges (running approximately parallel to the major axis), and several extremely sharp isolated pinnacles. Minimum depths are at one location and at four or more other locations. During significant ice ages the bank emerged as an offshore island. The bank was first explored during 1988–1991 by divers in visits organized and led by Dr. Robert Schmieder of Cordell Expeditions ...

Bank (sea Floor)
An ocean bank, sometimes referred to as a fishing bank or simply bank, is a part of the seabed that is shallow compared to its surrounding area, such as a shoal or the top of an underwater hill. Somewhat like continental slopes, ocean bank slopes can upwell as tidal and other flows intercept them, sometimes resulting in nutrient-rich currents. Because of this, some large banks, such as Dogger Bank and the Grand Banks of Newfoundland, are among the richest fishing grounds in the world. There are some banks that were reported in the 19th century by navigators, such as Wachusett Reef, whose existence is doubtful. Types Ocean banks may be of volcanic nature. Banks may be carbonate or terrigenous. In tropical areas some banks are submerged atolls. As they are not associated with any landmass, banks have no outside source of sediments. Carbonate banks are typically platforms, rising from the ocean depths, whereas terrigenous banks are elevated sedimentary deposits. Seamounts, by ...
