Gascoyne Seamount
Gascoyne Seamount, also called Gascoyne Guyot or Gascoyne Tablemount, is a guyot in the Tasman Sea of the South Pacific Ocean. Geography Located east of the Australian coastal town of Bermagui, Gascoyne Seamount is the southernmost and youngest significant seamount of the Tasmantid Seamount Chain. This is an underwater mountain range extending some to the north. The Tasmantid Seamount Chain has resulted from the Indo-Australian Plate moving northward over a stationary hotspot. Geology The seamount is about 7 million years old. It incorporates a tropical to subtropical, very shallow water calcareous algal/encrusting foraminiferid biota, suggesting deposition in water deep. Age diagnostic forms have not been recovered. Gascoyne Seamount is named after HMAS ''Gascoyne'', one of two ships in the Royal Australian Navy assigned to Australian programs in the International Indian Ocean Expedition The International Indian Ocean Expedition (IIOE) was a large-scale multinational hydr ...

Bermagui, New South Wales
Bermagui is a town on the south coast of New South Wales, Australia in the Bega Valley Shire. It lies on the shores of the southern end of Horseshoe Bay. The name is derived from the Dyirringanj word, ''permageua'', possibly meaning "canoe with paddles". History A wharf was built in Horseshoe Bay in 1888 for the coastal trade. The port was serviced by the Illawarra and South Coast Steam Navigation Company. A 1910 article, "Bermagui – In a Strange Sunset", published by Henry Lawson in '' The Bulletin'' describes a steamer journey from Bermagui to Sydney. Lawson was probably travelling with the Illawarra Steam Navigation Company. In 1880, the Government geologist, Lamont Young, and four others disappeared while on a boat trip from Bermagui. Their boat was found near Mystery Bay, which is about 15 kilometres north of Bermagui, midway between Bermagui and Narooma, near Tilba. The bay received its name because of the disappearance.

Calcareous
Calcareous () is an adjective meaning "mostly or partly composed of calcium carbonate", in other words, containing lime or being chalky. The term is used in a wide variety of scientific disciplines. In zoology ''Calcareous'' is used as an adjectival term applied to anatomical structures which are made primarily of calcium carbonate, in animals such as gastropods, i.e., snails, specifically about such structures as the operculum, the clausilium, and the love dart. The term also applies to the calcium carbonate tests of often more or less microscopic Foraminifera. Not all tests are calcareous; diatoms and radiolaria have siliceous tests. The molluscs are calcareous, as are calcareous sponges ( Porifera), that have spicules which are made of calcium carbonate. In botany ''Calcareous grassland'' is a form of grassland characteristic of soils containing much calcium carbonate from underlying chalk or limestone rock. In medicine The term is used in pathology, for example i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Miocene Volcanoes
The Miocene ( ) is the first geological epoch of the Neogene Period and extends from about (Ma). The Miocene was named by Scottish geologist Charles Lyell; the name comes from the Greek words (', "less") and (', "new") and means "less recent" because it has 18% fewer modern marine invertebrates than the Pliocene has. The Miocene is preceded by the Oligocene and is followed by the Pliocene. As Earth went from the Oligocene through the Miocene and into the Pliocene, the climate slowly cooled towards a series of ice ages. The Miocene boundaries are not marked by a single distinct global event but consist rather of regionally defined boundaries between the warmer Oligocene and the cooler Pliocene Epoch. During the Early Miocene, the Arabian Peninsula collided with Eurasia, severing the connection between the Mediterranean and Indian Ocean, and allowing a faunal interchange to occur between Eurasia and Africa, including the dispersal of proboscideans into Eurasia. During the late ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Seamounts Of The Tasman Sea
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] |
International Indian Ocean Expedition
The International Indian Ocean Expedition (IIOE) was a large-scale multinational hydrographic survey of the Indian Ocean which took place from September 1, 1959, to December 31, 1965. It involved over 45 research vessels from 14 countries. It was sponsored by the Scientific Committee on Oceanographic Research, and later by the Intergovernmental Oceanographic Commission. Vast amounts of data on oceanic organisms were collected. For example, specimens of Polychaetes (marine worms) were collected from the coasts of the Indian Ocean.

HMAS ''Gascoyne'' (K354/F354/A276) was a that served in the Royal Australian Navy (RAN). Laid down in 1942 and commissioned in 1943, the frigate served during World War II, before being placed in reserve in 1946. Reactivated in 1959, ''Gascoyne'' was reclassified as a survey and research ship, a role she fulfilled until she was decommissioned again in 1966, and sold for scrap in 1972. Construction ''Gascoyne'' was laid down by Mort's Dock & Engineering Company, Sydney on 3 July 1942.

Algal
Algae (; singular alga ) is an informal term for a large and diverse group of photosynthetic eukaryotic organisms. It is a polyphyletic grouping that includes species from multiple distinct clades. Included organisms range from unicellular microalgae, such as ''Chlorella,'' ''Prototheca'' and the diatoms, to multicellular forms, such as the giant kelp, a large brown alga which may grow up to in length. Most are aquatic and autotrophic (they generate food internally) and lack many of the distinct cell and tissue types, such as stomata, xylem and phloem that are found in land plants. The largest and most complex marine algae are called seaweeds, while the most complex freshwater forms are the ''Charophyta'', a division of green algae which includes, for example, ''Spirogyra'' and stoneworts. No definition of algae is generally accepted. One definition is that algae "have chlorophyll ''a'' as their primary photosynthetic pigment and lack a sterile covering of cells around their ...
