RV ''Sarmiento de Gamboa'' is an oceanographic research vessel operated by the Spanish National Research Council. It is used globally to study ''eg.'' ocean circulation, marine biodiversity, fishery resources, and climate change. Background Its construction was authorized by the Spanish Government in 2004, and it was launched in 2006 in the presence of Queen Sofia. It was built by Construcciones Navales P.

Plankton
Plankton are the diverse collection of organisms that drift in Hydrosphere, water (or atmosphere, air) but are unable to actively propel themselves against ocean current, currents (or wind). The individual organisms constituting plankton are called plankters. In the ocean, they provide a crucial source of food to many small and large aquatic organisms, such as bivalves, fish, and baleen whales. Marine plankton include bacteria, archaea, algae, protozoa, microscopic fungi, and drifting or floating animals that inhabit the saltwater of oceans and the brackish waters of estuaries. fresh water, Freshwater plankton are similar to marine plankton, but are found in lakes and rivers. Mostly, plankton just drift where currents take them, though some, like jellyfish, swim slowly but not fast enough to generally overcome the influence of currents. Although plankton are usually thought of as inhabiting water, there are also airborne versions that live part of their lives drifting in the at ...

History Of Research Ships
The research ship had origins in the early voyages of exploration. By the time of James Cook's HM Bark Endeavour, ''Endeavour'', the essentials of what today we would call a research ship are clearly apparent. In 1766, the Royal Society hired Cook to travel to the Pacific Ocean to observe and record the transit of Venus across the Sun. The ''Endeavour'' was a sturdy boat, well designed and equipped for the ordeals she would face, and fitted out with facilities for her research personnel, Joseph Banks. And, as is common with contemporary research vessels, ''Endeavour'' carried out more than one kind of research, including comprehensive hydrographic survey work. Some other notable early research vessels were HMS Beagle, HMS ''Beagle'', RV Calypso, RV ''Calypso'', HMS Challenger (1858), HMS ''Challenger'', and the Endurance (1912 ship), ''Endurance'' and Terra Nova (ship), ''Terra Nova''.

Antarctic
The Antarctic (, ; commonly ) is the polar regions of Earth, polar region of Earth that surrounds the South Pole, lying within the Antarctic Circle. It is antipodes, diametrically opposite of the Arctic region around the North Pole. The Antarctic comprises the continent of Antarctica, the Kerguelen Plateau, and other list of Antarctic and Subantarctic islands, island territories located on the Antarctic Plate or south of the Antarctic Convergence. The Antarctic region includes the ice shelf, ice shelves, waters, and all the island territories in the Southern Ocean situated south of the Antarctic Convergence, a zone approximately wide and varying in latitude seasonally. The region covers some 20 percent of the Southern Hemisphere, of which 5.5 percent (14 million km2) is the surface area of the Antarctica continent itself. All of the land and ice shelf, ice shelves south of 60th parallel south, 60°S latitude are administered under the Antarctic Treaty System. Biogeograph ...

Methane
Methane ( , ) is a chemical compound with the chemical formula (one carbon atom bonded to four hydrogen atoms). It is a group-14 hydride, the simplest alkane, and the main constituent of natural gas. The abundance of methane on Earth makes it an economically attractive fuel, although capturing and storing it is difficult because it is a gas at standard temperature and pressure. In the Earth's atmosphere methane is transparent to visible light but absorbs infrared radiation, acting as a greenhouse gas. Methane is an Organic chemistry, organic Organic compound, compound, and among the simplest of organic compounds. Methane is also a hydrocarbon. Naturally occurring methane is found both below ground and under the seafloor and is formed by both geological and biological processes. The largest reservoir of methane is under the seafloor in the form of methane clathrates. When methane reaches the surface and the Atmosphere of Earth, atmosphere, it is known as atmospheric methane. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Undersea Mountain Range
Undersea mountain ranges are mountain ranges that are mostly or entirely underwater, and specifically under the surface of an ocean. If originated from current tectonic forces, they are often referred to as a ''mid-ocean ridge''. In contrast, if formed by past above-water volcanism, they are known as a '' seamount chain''. The largest and best known undersea mountain range is a mid-ocean ridge, the Mid-Atlantic Ridge The Mid-Atlantic Ridge is a mid-ocean ridge (a Divergent boundary, divergent or constructive Plate tectonics, plate boundary) located along the floor of the Atlantic Ocean, and part of the List of longest mountain chains on Earth, longest mountai .... It has been observed that, "similar to those on land, the undersea mountain ranges are the loci of frequent volcanic and earthquake activity".Martin F. Price, Alton C. Byers, Donald A.

Blanes Canyon
The Blanes canyon is an underwater canyon that forms the underwater valley located off the coast of Blanes, in the province of Girona, Catalonia, Spain. This underwater canyon is a significant geological feature of the Balearic Sea and plays an important role in the region's marine biodiversity. Geography The canyon extends from the continental shelf to depths exceeding . Its formation is due to erosive and tectonic processes that have shaped the seabed over millions of years. Its head is about from the coast, it is a valley at the bottom of the sea about long and wide, with vertical walls that go down to a depth of about . The mouth of the canyon is located near the mouth of the Tordera River, which contributes to the mixing of fresh and salt water in the area. Biodiversity The Blanes canyon is home to a great diversity of marine species. Among the benthic organisms that inhabit the canyon are corals, sponges, and a variety of invertebrates. In addition, it is a passage a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Malaspina Expedition 2010
The Malaspina circumnavigation expedition was an interdisciplinary research project to assess the impact of global change on the oceans and explore their biodiversity. The 250 scientists on board the ''BIO Hesperides, Hespérides'' and RV Sarmiento de Gamboa, RV ''Sarmiento de Gamboa'' embarked on an eight-month expedition (starting in December 2010) scientific research with training for young researchers - advancing marine science and fostering the public understanding of science. The project was under the umbrella of the Spanish Ministry of Science and Innovation's Consolider – Ingenio 2010 programme and was led by the Spanish National Research Council (CSIC) with the support of the Spanish Navy. It is named after the original scientific Malaspina Expedition between 1789 and 1794, that was commanded by Alejandro Malaspina. Due to Malaspina's involvement in a conspiracy to overthrow the Spanish government, he was jailed upon his return and a large part of the expedition's repo ...

Mediolabrus Comicus
''Mediolabrus comicus'', known previously as ''Minidiscus comicus'', is a species of nanophytoplanktonic centric diatoms within the family Thalassiosiraceae. Its cells have diameters as small as 1.9 ''μ''m, which makes ''M.'' ''comicus'' one of the smallest known diatoms and brings it near to the theoretical lower size limit for photosynthetic eukaryotes. Taxonomy ''Mediolabrus comicus'' was originally described as ''Minidiscus comicus'', but in 2020, it was transferred based on molecular phylogenetics to a newly erected genus ''Mediolabrus'', as its type species. Morphology and ultrastructure Cells of ''M.'' ''comicus'' have diameters between 1.9 and 6.0 μm. The larger cells are discoidal with flat valve faces (ends of the Frustule, siliceous shell), while the smaller ones are spherical or even oblong. Valve margins are very narrow and marginal areolae (small regularly repeated pores) terminate close to the valve edge. There are 6–8 areolae per 1&nbs ...
