| In summary, we interpret Unit II as a fragment of a volcanic seamount incorporated into an Early Palaeozoic accretionary prism. |
|
| On September 25 signals from the seamount ceased when a transmission cable that carried the signals to land was cut by a deep-sea trawler. |
|
| In the northwest Pacific you can see a whole series of seamount chains that were formed by hotspots. |
|
| A seamount capped by limestone was incorporated into the accretionary prism north of the arc in Cambrian-Early Ordovician time. |
|
| As the seamount sinks or its peak erodes, the seamount will disappear beneath the water leaving the coral ring. |
|
| The region in question can be a particular part of a seamount, an individual seamount, a single chain of seamounts or even a whole ocean. |
|
| A maximum age is indicated by the Cambrian Akaz seamount in an accretionary prism, the presence of which implies the existence of a trench adjacent to the arc. |
|
| Atoll: A horseshoe or circular array of islands, capping a coral reef system perched around an oceanic volcanic seamount. |
|
| At least one seamount chain, the New England Seamounts, lies in the northwestern Atlantic. |
|
| The Bowie is the shallowest seamount in Canada's Pacific waters and one of Earth'smost biologically rich submarine volcanoes. |
|
| No seamount chains have been reported from the Indian Ocean, possibly because that basin has been less extensively surveyed. |
|
| In contrast, oceanic island, oceanic plateau and seamount volcanism is distinctive in composition and eruptive style from the activity at plate margins. |
|
| Studied only sparsely for decades, NOAA expeditions to the seamount in 2002 and 2006 cast light upon its unique deep-sea coral ecosystem. |
|
| Provide protection to this seamount chain and the rich diversity of marine life its supports. |
|
| Then in 2002, Rusty gave Greg his first Surfer magazine cover by towing him into a monolithic 60-plus-footer at the Cortes Bank, a treacherous seamount 100 miles off the San Diego coast. |
|
| The Pacific Ocean contains several long seamount chains, formed by hotspot volcanism. |
|
| The archipelago is formed by high points on the rim of the caldera of a submarine volcano that forms a seamount. |
|
| A series of ridges and seamount chains produced by hotspots pass over the Indian Ocean. |
|
| This would suggest that either the eustatic rise in sea level for the seamount is minimal, which counters global assumptions and local data, or that there is a problem with the GPS reference system. |
|
| Probably the shallowest seamount in Canada's Pacific waters, it rises from a depth of more than 3,000 metres to approximately 20 metres below the sea surface. |
|
|
|
| The accident of elevation marks the difference between its existence as an unclaimable seamount — no more than a shipping hazard — and as a potentially hotly contested piece of actual, dry-land real estate. |
|
| One such gap was closed in January, 2005, when an American nuclear submarine making 33 knots 500 feet beneath the surface crashed headlong into an uncharted seamount 360 miles southeast of Guam. |
|
| Those amendments relate to provisions on bottom fishing, closed areas to ensure seamount protection, labelling requirements and additional port state measures. |
|
| However recent information would indicate that the rate of relative sea level rise of the Bermuda seamount can be explained by subsidence observed with vertical motion GPS observations. |
|
| Seamount chains occur in all three major ocean basins, with the Pacific having the most number and most extensive seamount chains. |
|
| Which of these two process involved in the formation of a seamount has a profound effect on its eruptive materials. |
|
| With eruptions becoming infrequent and the seamount losing its ability to maintain itself, the volcano starts to erode. |
|
| One of the primary ecological havens on the seamount is its deep sea coral garden, and many of the specimens noted were over a century old. |
|
| Another such seamount is Bowie Seamount, which has also been declared a marine protected area by Canada for its ecological richness. |
|
| One major seamount risk is that often, in the late of stages of their life, extrusions begin to seep in the seamount. |
|
| The Walvis Ridge is one of few examples of a hotspot seamount chain that links a flood basalt province to an active hotspot. |
|
| The primary productivity of the epipelagic waters above the submerged peak can often be enhanced by the hydrographic conditions of the seamount. |
|
| Pufahl discusses the manner in which phosphorus is concentrated in insular, seamount, and continental margin phosphorites, and compares phosphorites in upwelling vs. |
|
| These explosions seemed to come from an unnamed seamount on the northern side of the ridge and are thought to be unrelated to the Tristan hotspot. |
|
| Due to the larger populations of fish in these areas overexpoitation by the fishing industry has caused some seamount fauna populations to decrease considerably. |
|
| This is finally capped by alkalic flows late in its eruptive history, as the link between the seamount and its source of volcanism is cut by crustal movement. |
|
| Possibly the best ecologically studied seamount in the world is Davidson Seamount, with six major expeditions recording over 60,000 species observations. |
|
| The company is interested in pursuing additional geologic and geophysical surveys along the Eratosthenes seamount, to the south of the island, he said. |
|
| Local increases in chlorophyll a, enhanced carbon incorporation rates and changes in phytoplankton species composition were associated with the seamount. |
|
| It is also possible that the high densities of fishes has more to do with the fish life histories and interaction with the benthic fauna of the seamount. |
|
|
|
| No volcanic or clastic sedimentary rocks were obtained from Cavalli Seamount. |
|
| The second problem that could crop up is that the SAGE project hinges on an offshore gas compression station on Qualhat Seamount, about 300km from the Omani coast. |
|
| A catastrophic collapse at Detroit Seamount flattened its whole structure extensively. |
|
| The latter may have originated as dispersed parts of ancient mantle plumes similar to a modern plume responsible for the formation of the intraplate Bowie Seamount. |
