From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. The arc consists of seven main volcanic islands, and a number of smaller volcanic islands and seamounts. Therefore, the variation in such ratios in basalts from oceanic basins can be used to document the range of source compositional variations present beneath oceanic spreading systems or seamounts. We interpret these basalts of intra-plate origin as having originated from a geochemically enriched (in terms of incompatible elements) component, possibly formed as seamounts on ocean crust. Although the location and extent of the island have not been discussed, we note that it coincides approximately with a chain of seamounts lying parallel to the coastline. However, an origin in seamount alkaline basalt cannot be excluded. Far from plate boundaries, we encounter examples of isostasy at intracratonic basins, mid-plate hotspot swells and seamount chains. The parasite was absent from epipelagic pre-recruit fish but common on the seamount population. Identification of new recruits to the seamount was based on the absence of mature parasites. Unregulated bottom gear can also reach submerged mountains or seamounts, bulldozing their way across the ocean floor and destroying all life in their path. From Europarl Parallel Corpus - English We must include here cold-water corals and seamounts, which shelter rich and often unique ecosystems. From Europarl Parallel Corpus - English Various studies have confirmed the sensitive nature of deep-water habitats, such as the deep-water coral reef, thermal vents and feeding grounds for fish of sea banks and seamounts. From Europarl Parallel Corpus - English Away from seamounts, the pelagic sequence is dominated by chert and pelagic clay, with little carbonate. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license.

From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. The reason for this is that the fishes that are targeted over seamounts are typically long-lived, slow-growing, and slow-maturing. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. Before seamounts and their oceanographic impact can be fully understood, they must be mapped, a daunting task due to their sheer number.
