Salinity
Salinity () is the saltiness or amount of salt (chemistry), salt dissolved in a body of water, called saline water (see also soil salinity). It is usually measured in g/L or g/kg (grams of salt per liter/kilogram of water; the latter is dimensionless and equal to per mille, ‰). Salinity is an important factor in determining many aspects of the chemistry of natural waters and of biological processes within it, and is a state function, thermodynamic state variable that, along with temperature and pressure, governs physical characteristics like the density and heat capacity of the water. A contour line of constant salinity is called an ''isohaline'', or sometimes ''isohale''. Definitions Salinity in rivers, lakes, and the ocean is conceptually simple, but technically challenging to define and measure precisely. Conceptually the salinity is the quantity of dissolved salt content of the water. Salts are compounds like sodium chloride, magnesium sulfate, potassium nitrate, and sod ...

Landforms Of Chubut Province
A landform is a land feature on the solid surface of the Earth or other planetary body. They may be natural or may be anthropogenic (caused or influenced by human activity). Landforms together make up a given terrain, and their arrangement in the landscape is known as topography. Landforms include hills, mountains, canyons, and valleys, as well as shoreline features such as bays, peninsulas, and seas, including submerged features such as mid-ocean ridges, volcanoes, and the great oceanic basins. Physical characteristics Landforms are categorized by characteristic physical attributes such as elevation, slope, orientation, structure stratification, rock exposure, and soil type. Gross physical features or landforms include intuitive elements such as berms, cliffs, hills, mounds, peninsulas, ridges, rivers, valleys, volcanoes, and numerous other structural and size-scaled (e.g. ponds vs. lakes, hills vs. mountains) elements including various kinds of inland and oceanic waterbod ...

Sea Lion
Sea lions are pinnipeds characterized by external ear flaps, long foreflippers, the ability to walk on all fours, short and thick hair, and a big chest and belly. Together with the fur seals, they make up the family Otariidae, eared seals. The sea lions have six extant and one extinct species (the Japanese sea lion) in five genera. Their range extends from the subarctic to tropical waters of the global ocean in both the Northern and Southern Hemispheres, with the notable exception of the northern Atlantic Ocean. Sea lions have an average lifespan of 20–30 years. A male California sea lion weighs on average about and is about long, while the female sea lion weighs and is long. The largest sea lions are Steller's sea lions, which can weigh and grow to a length of . Sea lions consume large quantities of food at a time and are known to eat about 5–8% of their body weight (about ) at a single feeding. Sea lions can move around in water and at their fastest they ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Southern Right Whale
The southern right whale (''Eubalaena australis'') is a baleen whale, one of three species classified as right whales belonging to the genus ''Eubalaena''. Southern right whales inhabit oceans south of the Equator, between the latitudes of 20° and 60° south. In 2009 the global population was estimated to be approximately 13,600. Taxonomy Right whales were first classified in the genus '' Balaena'' in 1758 by Carl Linnaeus, who at the time considered all right whales (including the bowhead) to be a single species. In the 19th and 20th centuries the family Balaenidae was the subject of great taxonometric debate. Authorities have repeatedly recategorised the three populations of right whale plus the bowhead whale, as one, two, three or four species, either in a single genus or in two separate genera. In the early whaling days, they were all thought to be a single species, ''Balaena mysticetus''. The southern right whale was initially described as ''Balaena australis'' by Des ...

Chacabuco Port
Puerto Chacabuco is a Chilean town in Aisén, Chile, Aisén commune. Administratively it belongs to Aysén Province in Aysén del General Carlos Ibáñez del Campo Region and is located at the head of Aisén Fjord. It is the main port of the region, a port of call for ships sailing to the Laguna San Rafael National Park and the terminus of a Navimag ferry service from Puerto Montt. The town is the site of important fish and shellfish processing plants. From the 1990s up to August 2003 there were plans for building Alumysa, an aluminium smelter in the town. Before the great burnings of the Patagonian forests and the eruption of Mount Hudson volcano in 1991 Puerto Aisén was the main port in the Aisén Fjord, but the ashes and earth erosion decreased the navigability of Aisén River and the port had to be moved further to the coast where Puerto Chacabuco now stands. Puerto Chacabuco is named after the corvette ''Chilean corvette Chacabuco (1866), Chacabuco'' with which Enrique Sim ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pico Truncado
Pico Truncado is a town and municipality in Santa Cruz Province in southern Argentina. In 1921, the village's railway station was the site of one of the few open engagements between the Argentine Army and anarchist strikers at the time of the events known as Patagonia rebelde, where the army suffered its only fatality of the campaign.''La Patagonia rebelde'' (tomo II: La masacre). Osvaldo Bayer, Editorial Galerna, Buenos Aires, (1972), p. 125 History Indigenous people Mentioning the history of the area now occupied by Pico Truncado means going back some 13,000 years. Lithic pieces found in the strata of the different caves explored, have made it possible to determine that the oldest inhabitants of the region were here 12,960 years ago, leaving even today, samples of their culture, cave expressions and the certainty that this place was about 13,000 years ago a place with abundant water and pastures that determined the approach of a large number and variety of species of the ti ...

Spider Crabs
The Majoidea are a superfamily of crabs which includes the various spider crabs. Taxonomy In "''A classification of living and fossil genera of decapod crustaceans''" De Grave and colleagues divided Majoidea into six families. The classification has since been revised, with subfamilies Epialtinae and Mithracinae being elevated to families and Hymenosomatidae being moved to its own superfamily. The family composition according to the World Register of Marine Species is as follows: * Epialtidae MacLeay, 1838 * Inachidae MacLeay, 1838 * Inachoididae Dana, 1851 * Macrocheiridae Dana, 1851 * Majidae Samouelle, 1819 – "true" spider crabs * Mithracidae Balss, 1929 * Oregoniidae Garth, 1958 * Priscinachidae Breton, 2009 Notable species within the superfamily include: * Japanese spider crab (''Macrocheira kaempferi''), the largest living species of crab, found on the bottom of the Pacific Ocean. * '' Libinia emarginata'', the portly spider crab, a species of crab found in est ...

Lobsters
Lobsters are malacostracans decapod crustaceans of the family Nephropidae or its synonym Homaridae. They have long bodies with muscular tails and live in crevices or burrows on the sea floor. Three of their five pairs of legs have claws, including the first pair, which are usually much larger than the others. Highly prized as seafood, lobsters are economically important and are often one of the most profitable commodities in the coastal areas they populate. Commercially important species include two species of '' Homarus'' from the northern Atlantic Ocean and scampi (which look more like a shrimp, or a "mini lobster")—the Northern Hemisphere genus '' Nephrops'' and the Southern Hemisphere genus '' Metanephrops''. Distinction Although several other groups of crustaceans have the word "lobster" in their names, the unqualified term "lobster" generally refers to the clawed lobsters of the family Nephropidae. Clawed lobsters are not closely related to spiny lobsters or sli ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
