The Lord Howe Seamount Chain of which Gifford Guyot is an eruptive centre, and part of a pair of coral-capped guyots, formed during the Miocene. The Gifford Marine Park is co-located off the Queensland coast near Brisbane.

They both raise from an abyssal plain below sea level to generally flat summits that are about below sea level. This summit plateau is about for the unnamed guyot), and in area for Gifford Guyot itself.

Coral Sea
The Coral Sea () is a marginal sea of the South Pacific off the northeast coast of Australia, and classified as an interim Australian bioregion. The Coral Sea extends down the Australian northeast coast. Most of it is protected by the French Natural Park of the Coral Sea (french: Parc Naturel de la Mer de Corail) and the Australian Coral Sea Marine Park. The sea was the location for the Battle of the Coral Sea, a major confrontation during World War II between the navies of the Empire of Japan, and the United States and Australia. The sea contains numerous islands and reefs, as well as the world's largest reef system, the Great Barrier Reef (GBR), which was declared a World Heritage Site by UNESCO in 1981. All previous oil exploration projects were terminated at the GBR in 1975, and fishing is restricted in many areas. The reefs and islands of the Coral Sea are particularly rich in birds and aquatic life and are a popular tourist destination, both domestically and internat ...

Banc Capel is a guyot, or flat-topped underwater volcano, in the Coral Sea. Description Banc Capel is a guyot – a former atoll with steep sides and a flat top – and is swept by strong currents. There are no sandy or muddy substrates, the surface being occupied by rocks or gravel scree. Biodiversity Banc Capel is inhabited by species including '' Nassarius alabasteroides'' and ''Laurentaeglyphea''. It is dominated by sponges, including the genus '' Phloedictyon'' and gorgonians.

Volcanoes Of Zealandia
A volcano is a rupture in the crust of a planetary-mass object, such as Earth, that allows hot lava, volcanic ash, and gases to escape from a magma chamber below the surface. On Earth, volcanoes are most often found where tectonic plates are diverging or converging, and most are found underwater. For example, a mid-ocean ridge, such as the Mid-Atlantic Ridge, has volcanoes caused by divergent tectonic plates whereas the Pacific Ring of Fire has volcanoes caused by convergent tectonic plates. Volcanoes can also form where there is stretching and thinning of the crust's plates, such as in the East African Rift and the Wells Gray-Clearwater volcanic field and Rio Grande rift in North America. Volcanism away from plate boundaries has been postulated to arise from upwelling diapirs from the core–mantle boundary, deep in the Earth. This results in hotspot volcanism, of which the Hawaiian hotspot is an example. Volcanoes are usually not created where two tectonic plates slide pa ...

Ball's Pyramid
Ball's Pyramid is an erosional remnant of a shield volcano and caldera lying southeast of Lord Howe Island in the Pacific Ocean. It is high, while measuring in length and only across, making it the tallest volcanic stack in the world. Ball's Pyramid is part of the Lord Howe Island Marine Park in Australia and is over northeast of Sydney, New South Wales. Steep, eroded, and formed 6.4 million years ago, Ball's Pyramid is positioned in the centre of a submarine shelf and is surrounded by rough seas, making any approach difficult. History Discovery The pyramid is named after Royal Navy Lieutenant Henry Lidgbird Ball, who reported discovering it in 1788. On the same voyage, Ball also reported discovering Lord Howe Island. In ''The Voyage of Governor Phillip to Botany Bay with an Account of the Establishment of the Colonies of Port Jackson and Norfolk Island'' (1789), Arthur Phillip gives this description of the area around Ball's Pyramid.. before describing Lord H ...

Elizabeth Reef
Elizabeth Reef, located at is a coral reef in the Coral Sea. The reef is separated by a deep oceanic pass, some 47 km wide, from nearby Middleton Reef, both of which are part of the underwater plateau known as the Lord Howe Rise. It is around 150 km from Lord Howe Island and 600 km from the New South Wales coast of Australia. ThEnvironment, Sport and Territories Legislation Amendment Act 1997included Elizabeth Reef in Australia's Coral Sea Islands Territory. It is the southernmost coral atoll in the world and one of the southernmost platform reefs in the world. It measures 10.5 km by 6.1 km. Despite the relatively high latitude, a wide variety of flora and fauna exists on the reef and in the surrounding waters due to their location where tropical and temperate ocean currents converge. At low tide most of the reef flat is exposed; at high tide, both a cay and a sand spit are visible. Elizabeth Island, with a diameter of about 50 m, is one metre ...

Middleton Reef
Middleton Reef is a coral reef in the Coral Sea. It is separated by a deep oceanic pass some 47 km wide from nearby Elizabeth Reef, forming part of the Lord Howe Rise underwater plateau. It is around 230 km from Lord Howe Island and 555 km from the coast of New South Wales. In 1997 thEnvironment, Sport and Territories Legislation Amendment Bill 1996included the reef in Australia's Coral Sea Islands Territory. It is among the southernmost platform reefs in the world. Despite its relatively high latitude, there is a wide variety of flora and fauna on the reef and in the surrounding waters, due to converging tropical and temperate ocean currents. It is about 8.9 km long by 6.3 km wide. At low tide most of the reef flat is exposed, at high tide only one cay is visible, The Sound, 100 m by 70 m and one metre above sea level.

Lord Howe Island
Lord Howe Island (; formerly Lord Howe's Island) is an irregularly crescent-shaped volcanic remnant in the Tasman Sea between Australia and New Zealand, part of the Australian state of New South Wales. It lies directly east of mainland Port Macquarie, northeast of Sydney, and about southwest of Norfolk Island. It is about long and between wide with an area of , though just of that comprise the low-lying developed part of the island. Along the west coast is a sandy semi-enclosed sheltered coral reef lagoon. Most of the population lives in the north, while the south is dominated by forested hills rising to the highest point on the island, Mount Gower (). The Lord Howe Island Group comprises 28 islands, islets, and rocks. Apart from Lord Howe Island itself, the most notable of these is the volcanic and uninhabited Ball's Pyramid about to the southeast of Howe. To the north lies a cluster of seven small uninhabited islands called the Admiralty Group. The first repo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Seamount
A seamount is a large geologic landform that rises from the ocean floor that does not reach to the water's surface (sea level), and thus is not an island, islet or cliff-rock. Seamounts are typically formed from extinct volcanoes that rise abruptly and are usually found rising from the seafloor to in height. They are defined by oceanographers as independent features that rise to at least above the seafloor, characteristically of conical form.IHO, 2008. Standardization of Undersea Feature Names: Guidelines Proposal form Terminology, 4th ed. International Hydrographic Organization and Intergovernmental Oceanographic Commission, Monaco. The peaks are often found hundreds to thousands of meters below the surface, and are therefore considered to be within the deep sea. 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. After they have subsided and sunk below the sea surface such flat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
