| Since the Early Miocene, thermal decay has led to the subsidence of Cavalli Seamount and other, volcanic, seamounts in the South Fiji Basin. |
|
| These deep water whales are usually found in the vicinity of seamounts and continental slopes in temperate and subarctic waters. |
|
| In particular, seamounts on the subducting plate may serve as earthquake nucleation sites or asperities. |
|
| As the rays hover over the seamounts, the diminutive angelfish come up and feed on the parasites that attach to the rays' skin. |
|
| The fish dwells deep in the ocean and travels long distances to spawn above seamounts in the Southern Hemisphere. |
|
| More recently, large concentrations of orange roughy were uncovered on seamounts off Australia and New Zealand, and just as immediately decimated. |
|
| It would follow a surface of equal gravity, elevated by a few meters over submarine ridges and seamounts and depressed over trenches. |
|
| This process of volcano growth and death, over many millions of years, has left a long trail of volcanic islands and seamounts across the Pacific Ocean floor. |
|
| Cold water reefs, seamounts, corals, hydrothermal vents and sponge beds are increasingly at risk from human activities. |
|
| The concentration of fish stocks around seamounts has made them attractive fishing grounds. |
|
| The predominant feature of the shoreline is the rocky cliffs, extending under water to encompass a lush kelp forest, submarine reefs and offshore seamounts. |
|
| The resolution specifically mentions protecting seamounts, hypothermal vents and cold water corals. |
|
| 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. |
|
| These same factors however also render seamounts vulnerable to human pressures. |
|
| You have seamounts with incredible biodiversity being destroyed around the world. |
|
| We must include here cold-water corals and seamounts, which shelter rich and often unique ecosystems. |
|
| The seamounts have an east-west strike whereas the sedimentary graben is trending north-south. |
|
| The seabed has some outstanding features, with seamounts and deep underwater canyons where giant squid and large sponges can be found. |
|
| The rich source of food around seamounts also encourages the growth of suspension feeders on the seafloor, such as corals. |
|
| He took advantage of the opportunity to record echo-sounding profiles across parts of the Pacific and discovered several flat-topped submarine mountains or seamounts. |
|
|
|
| The process of fencing off seamounts is still at an early stage, though four clusters of them have been discovered and declared off-limits in the north-eastern Atlantic. |
|
| These flat-topped seamounts are called guyots. |
|
| Certain marine ecosystems such as seamounts, deep water corals and hydrothermal vents are threatened by fishing practices that can have destructive effects on the physical integrity of the habitat. |
|
| The weight of seamounts and volcanic islands causes a depression in the surrounding ocean crust, similar to the depression around a person sitting on a spring-filled cushion. |
|
| So far, more than 70 species of squid have been identified from the seamounts cruise, representing more than 20 percent of the global squid biodiversity. |
|
| If Canada pushed it, it might work, because then you'd have to have the European nations saying that they were for the destruction of the seamounts we've never surveyed. |
|
| Mobile bottom-contact gear can be destructive if it occurs in sensitive marine areas in a way that prohibits the sustainability of ecologically and biologically significant ecosystems, such as seamounts and cold-water corals. |
|
| Owing to the aggregating characteristics of some deep-sea fish species around marine habitats, such as seamounts for feeding or spawning purposes, the yield per unit effort can be very high. |
|
| Since 2006, as a precautionary measure, NAFO has closed to bottom fishing all the known seamounts in its Regulatory Area as well as a large coral area on the south end of the Grand Banks. |
|
| Marine life also flourishes around seamounts that rise from the depths, where fish and other sea life congregate to spawn and feed. |
|
| Frontal erosion is most active in the wake of seamounts being subducted beneath the forearc. |
|
| International research projects such as the Census of Marine Life are casting new light on the tiniest microbes and largest predators, from individual seamounts to the vast abyssal plains. |
|
| However, productive wild fisheries also exist in open oceans, particularly by seamounts, and inland in lakes and rivers. |
|
| There are thought to be up to an estimated 50,000 seamounts in the Pacific basin. |
|
| During the 1960s, Russia, Australia and New Zealand started to look for new stocks of fish and began to trawl the seamounts. |
|
| The Cretaceous guyots may have resulted from the northward drift of seamounts and reefs on the Pacific Plate away from the tropical zone of favourable growth. |
|
| Scattered across Panthalassa within 30° of the Triassic Equator were islands, seamounts, and volcanic archipelagoes, some associated with deposits of reef carbonates now found in western North America and other locations. |
|
| Unregulated bottom gear can also reach submerged mountains or seamounts, bulldozing their way across the ocean floor and destroying all life in their path. |
|
| However, the biota of seamounts and fracture zones within the Clarion-Clipperton Zone remain essentially unstudied so the uniqueness of associated biota cannot be assessed. |
|
| A previously unknown species of sea lily has turned up at seamounts more than 1,600 meters below the waves at sites off Antarctica. |
|
|
|
| There's an immediate threat to the biodiversity of seamounts, coral and other species from bottom trawling. |
|
| Nomadic species such as mackerels, tunas, and sharks form assemblages at seamounts. |
|
| This slope and its surrounding seamounts are the spawning ground for sardine, anchovy, and horse mackerel. |
|
| You can find them congregating around deeper wrecks and seamounts, where food sources are plentiful. |
|
| Orange roughy often live close to seamounts, sensitive underwater mountains that are scraped and disrupted by deep-sea trawlers. |
|
| They can be found in shallow subtidal areas, on the continental shelf, seamounts, to mid-ocean ridges and down to the abyssal plains of the deep ocean. |
|
| The distinct character of both hydrothermal vents and seamounts results in a level of species endemism that is higher than that found on the abyssal plain. |
|
| Besides, we are talking about areas where there is no continental shelf and therefore the places where fishing is possible are confined to small seamounts generally associated with those deep-water corals. |
|
| It was stressed that greater effort, in both technological and financial terms, was required in order to document information on biodiversity and the environmental conditions of the bathypelagic zone, trenches and seamounts. |
|
| Other protected areas safeguard unique features, such as fossil beds, seamounts, native petroglyphs, rare plants and animals, and areas of outstanding beauty. |
|
| Central to the case against bottom-fishing is the protection of underwater mountains, known as seamounts, which are especially rich in marine life of all kinds. |
|
| All volcanic seamounts follow a particular pattern of growth, activity, subsidence and eventual extinction. |
|
| Many seamounts also have hydrothermal vent communities, for example Suiyo and Loihi seamounts. |
|
| This is helped by geochemical exchange between the seamounts and the ocean water. |
|
| The effect that seamounts have on fish populations has not gone unnoticed by the commercial fishing industry. |
|
| The ecological conservation of seamounts is hurt by the simple lack of information available. |
|
| Corals from seamounts are also vulnerable, as they are highly valued for making jewellery and decorative objects. |
|
| Significant harvests have been produced from seamounts, often leaving coral beds depleted. |
|
| Much of what is known about seamounts ecologically is based on observations from Davidson. |
|
| The study of seamounts has been stymied for a long time by the lack of technology. |
|
|
|
| New species are observed or collected and valuable information is obtained on almost every submersible dive at seamounts. |
|
| Before seamounts and their oceanographic impact can be fully understood, they must be mapped, a daunting task due to their sheer number. |
|
| But with the constantly decreasing supply on land, many see oceanic mining as the destined future, and seamounts stand out as candidates. |
|
| Recent studies suggest there may be 30,000 seamounts in the Pacific, about 1,000 in the Atlantic Ocean and an unknown number in the Indian Ocean. |
|
| The benthic fauna of the seamounts is dominated by suspension feeders, including sponges and true corals. |
|
| They may live around features, such as seamounts, which have strong currents. |
|
| In addition, intense gravity highs are associated with the Anton Dohrn and Hebrides Terrace seamounts. |
|
| Nutrient-rich currents from the cold southern seas of the Antarctic swirl around volcanic seamounts that rise from vast deep abyssal plains. |
|
| They also recovered both older, tholeiitic and younger, alkalic capping lavas from some of the southern seamounts. |
|
| The geology of the deep shelves, seamounts, and guyots, around Hawaii are also poorly studied. |
|
| In recent years, several active seamounts have been observed, for example Loihi in the Hawaiian Islands. |
|
| Because of their abundance, seamounts are one of the most common marine ecosystems in the world. |
|
| Their aggregational effect has been noted by the commercial fishing industry, and many seamounts support extensive fisheries. |
|
| Because of their large numbers, many seamounts remain to be properly studied, and even mapped. |
|
| The Arctic Ocean has only 16 seamounts and no guyots, and the Mediterranean and Black seas together have only 23 seamounts and 2 guyots. |
|
| This long chain of islands and seamounts extends thousands of kilometers northwest from the island of Hawaii. |
|
| If all known seamounts were collected into one area, they would make a landform the size of Europe. |
|
| 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. |
|
| It was scored everywhere with canyons, trenches and crevasses and dotted with volcanic seamounts that he called guyots after an earlier Princeton geologist named Arnold Guyot. |
|
| Seamounts are very poorly studied, with only 350 of the estimated 100,000 seamounts in the world having received sampling, and fewer than 100 in depth. |
|
|
|
| Interactions between seamounts and underwater currents, as well as their elevated position in the water, attract plankton, corals, fish, and marine mammals alike. |
|
| It's like, you're going over an area no one's ever seen before, and you don't think it can continue, but the instruments keep showing more and more seamounts. |
|
| For a long time it has been surmised that many pelagic animals visit seamounts to gather food, but proof this of this aggregating effect has been lacking. |
|
| The majority of seamounts have already completed their eruptive cycle, so access to early flows by researchers is limited by late volcanic activity. |
|
| Dry prominence is also useful for measuring submerged seamounts. |
|
| Otherwise, seamounts tend not to form distinctive chains in the Indian and Southern Oceans, but rather their distribution appears to be more or less random. |
|
| The deep ocean floor is thought to be fairly flat with occasional deeps, abyssal plains, trenches, seamounts, basins, plateaus, canyons, and some guyots. |
|
| Most seamounts are built by one of two volcanic processes, although some, such as the Christmas Island Seamount Province near Australia, are more enigmatic. |
|
| Flat topped seamounts called guyots are well known in the Pacific. |
|
| They are the products of the explosive activity of seamounts that are near the water's surface, and can also form from mechanical wear of existing volcanic rock. |
|
| Many seamounts show signs of intrusive activity, which is likely to lead to inflation, steepening of volcanic slopes, and ultimately, flank collapse. |
|
| Marine mammals, sharks, tuna, and cephalopods all congregate over seamounts to feed, as well as some species of seabirds when the features are particularly shallow. |
|
| The eastern segment of the fault is complex and characterised by a series of seamounts and ridges separating the Tores and Horseshoe abyssal plains. |
|
| Some seamounts have not been mapped and thus pose a navigational danger. |
|
| For a long time it has been surmised that many pelagic animals visit seamounts as well, to gather food, but proof of this aggregating effect has been lacking. |
|
| Older seamounts east of these hotspot trails formed at the edge of the African swell where the oceanic crust was spreading apart and are not the product of hotspot volcanism. |
