Marinelli Creek
Marinelli Creek is a watercourse whose headwaters emerge from the melting of Marinelli Glacier in Tierra del Fuego, Chile. Marinelli Creek discharges to Ainsworth Bay, a notable inlet along the Almirantazgo Fjord Almirantazgo Fjord ( es, Fiordo Almirantazgo), also known as Almirantazgo Sound ( es, Seno Almirantazgo) or Admiralty Sound, is a Chilean fjord located in the far south of the country at .Earth Info, ''earth-info.nga.mil'' webpage: .

Watercourse
A stream is a continuous body of surface water flowing within the bed and banks of a channel. Depending on its location or certain characteristics, a stream may be referred to by a variety of local or regional names. Long large streams are usually called rivers, while smaller, less voluminous and more intermittent streams are known as streamlets, brooks or creeks. The flow of a stream is controlled by three inputs – surface runoff (from precipitation or meltwater), daylighted subterranean water, and surfaced groundwater (spring water). The surface and subterranean water are highly variable between periods of rainfall. Groundwater, on the other hand, has a relatively constant input and is controlled more by long-term patterns of precipitation. The stream encompasses surface, subsurface and groundwater fluxes that respond to geological, geomorphological, hydrological and biotic controls. Streams are important as conduits in the water cycle, instruments in groundwater ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Headwaters
The headwaters of a river or stream is the farthest place in that river or stream from its estuary or downstream confluence with another river, as measured along the course of the river. It is also known as a river's source. Definition The United States Geological Survey (USGS) states that a river's "length may be considered to be the distance from the mouth to the most distant headwater source (irrespective of stream name), or from the mouth to the headwaters of the stream commonly known as the source stream". As an example of the second definition above, the USGS at times considers the Missouri River as a tributary of the Mississippi River. But it also follows the first definition above (along with virtually all other geographic authorities and publications) in using the combined Missouri—lower Mississippi length figure in lists of lengths of rivers around the world. Most rivers have numerous tributaries and change names often; it is customary to regard the longest t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Marinelli Glacier
Marinelli Glacier is a tidewater glacier located in Alberto de Agostini National Park, Isla Grande de Tierra del Fuego. The glacier spills out from the backbone of the Cordillera Darwin and calves into Ainsworth Bay, an embayment of the Almirantazgo Fjord. The Marinelli Glacier is in a state of retreat, beginning at least as early as 1960B.L. Boyda, J.B. Andersona, J.S. Wellnerb and R.A. Fernández, 2008 and continuing to the present time.C.

Tierra Del Fuego
Tierra del Fuego (, ; Spanish for "Land of the Fire", rarely also Fireland in English) is an archipelago off the southernmost tip of the South American mainland, across the Strait of Magellan. The archipelago consists of the main island, Isla Grande de Tierra del Fuego, with an area of , and a group of many islands, including Cape Horn and Diego Ramírez Islands. Tierra del Fuego is divided between Chile and Argentina, with the latter controlling the eastern half of the main island and the former the western half plus the islands south of Beagle Channel and the southernmost islands. The southernmost extent of the archipelago is just north of latitude 56°S. The earliest known human settlement in Tierra del Fuego dates to approximately 8,000 BC. Europeans first explored the islands during Ferdinand Magellan's expedition of 1520. ''Tierra del Fuego'' and similar namings stem from sightings of the many bonfires that the natives built. Settlement by those of European descent and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
