AllRefer.com - Bellingshausen Sea, Antarctica (Antarctic Physical Geography) - Encyclopedia Bellingshausen Sea, part of the S Pacific Ocean, W Antarctica, SW of Cape Horn between the Antarctic Peninsula and Amundsen Sea. The sea is named after Russian explorer Fabian Gottlieb von Bellingshausen, who circumnavigated Antarctica in 1819. Major islands in the sea include Alexander I, Peter I (both named by Bellingshausen), and Charcot islands. reference.allrefer.com /encyclopedia/B/BellingsSea.html   (167 words)

Ba-Bm It is separated from the Tyrrhenian Sea to the east by Sardinia and Corsica and abuts the Alboran Sea to the west. It is mostly underlain by a small trough extending to the west of the Flores Trough and is bound by sills to the south (the 200 m Bali Strait and the 220 m Lombok Strait) and by a narrow, 600 m deep passage connecting it to the Makassar Stait to the north. The Bismarck Sea is bounded to the southwest by New Guinea and to the north, east, and south by the Bismarck Archipelago. stommel.tamu.edu /~baum/paleo/ocean/node3.html   (8033 words)

Feb 08 - Bellingshausen Sea   (Site not responding. Last check: 2007-11-02) The Bellinsghausen Sea is described as the area north, northwest and west of Alexander Island. The sea was not given its name until the French Antarctic Expedition to the same area in 1908 to 1910. There are a lot of icebergs and ice floes in the Bellingshausen Sea today, but during the last ice age this area was filled with ice that extended to the sea floor all across the continental shelf. www.antarctica.ac.uk /Living_and_Working/Diaries/RRS_James_Clark_Ross/antarctic2003_2004/13_20   (2164 words)

S.O.-Working Group Reports The gyral circulation of the Bellingshausen Sea is thought to contain a functional population of E. Sea ice in Antarctica is one of the most seasonal parameters on the surface of the earth. The potential study areas were the Bellingshausen Sea and adjacent waters to the east, but it was felt that because of logistic constraints of national ongoing and planned projects, other areas such as the Weddell Sea or Prydz Bay should be taken into consideration. www.usglobec.org /reports/so/so.chapter7.html   (9168 words)

DISCUSSION In the Ross Sea and the Weddell Sea, the concentrations of dissolved silica in the bottom waters bathing the continental slope and rise are typically 120-135 µmol/L (Jacobs, 1989; Rutgers van der Loeff and van Bennekom, 1989). At the continental margins in the Ross Sea and the Weddell Sea, the ratio of opal accumulation in the surface sediments to primarily produced opal in the surface water was estimated to be 0.1%-10% (DeMaster et al., 1996; Nelson et al., 1996; Schlüter et al., 1998). At present, the duration of sea-ice coverage in the Bellingshausen Sea is controlled by atmospheric heat supply and by upwelling of warm CDW (Hofmann et al., 1996; Jacobs and Comiso, 1997). www-odp.tamu.edu /publications/178_SR/chap_23/c23_5.htm   (4001 words)

Iceberg - Wikipedia, the free encyclopedia Icebergs are monitored worldwide by the U.S. National Ice Center (NIC), established in 1995, which produces analyses and forecasts of Arctic, Antarctic, Great Lakes, and Chesapeake Bay ice conditions. More than 95% of the data used in its sea ice analyses are derived from the remote sensors on polar-orbiting satellites that survey these remote regions of the Earth. Iceberg B15, which calved from the Ross Ice Shelf in 2000 and initially had an area of 11 000 km², was the largest iceberg ever recorded. en.wikipedia.org /wiki/Iceberg   (488 words)

EO News: Satellites Show Overall Increases in Antarctic Sea Ice Cover - August 22, 2002 Parkinson examined 21 years (1979-1999) of Antarctic sea ice satellite records and discovered that, on average, the area where southern sea ice seasons have lengthened by at least one day per year is roughly twice as large as the area where sea ice seasons have shortened by at least one day per year. The length of the sea ice season in any particular region or area refers to the number of days per year when at least 15 percent of that area is covered by sea ice. To calculate the lengths of the sea ice seasons, Parkinson used satellite data gridded to 25 by 25 kilometer grid cells for the Southern Ocean region. eobglossary.gsfc.nasa.gov /Newsroom/NasaNews/2002/2002082210350.html   (706 words)

ENSO - Wikipedia, the free encyclopedia El Niño and La Niña are officially defined as sustained sea surface temperature anomalies of magnitude greater than 0.5°C across the central tropical Pacific Ocean. The latter two and the Weddell Sea also become warmer and have higher atmospheric pressure. Positive values of the SOI are associated with stronger Pacific trade winds and warmer sea temperatures to the north of Australia, popularly known as a La Niña episode. en.wikipedia.org /wiki/El_Ni%C3%B1o   (2403 words)

Comparison of ERS-SAR Backscattering Coefficients with In Situ Measurements of the ... Present numerical sea ice models predict among others the ice drift and some characteristics of deformation, which may be related to the ice roughness. The SAR backscatter coefficients are correlated with these data, acquired in the Bellingshausen and Amundsen Seas in February 1994 during an expedition of RV Polarstern. In a first step two significantly different sea-ice regimes are identified: The ice in the central Bellingshausen Sea was moderately deformed with mean thicknesses of 1 to 1.2 m, while the mean ice thickness in the Amundsen Sea ranged from 2 to 3 m. earth.esa.int /symposia/ers97/papers/martin   (340 words)

The Bellingshausen Sea Bellingshausen Sea is located between Thurston Island on the West and the Antarctic Peninsula on the East. In younger history, the ice extent in the Bellingshausen Sea decreased at a rate of roughly 8 percent per decade. This may suggest that the ice cover lost in the Bellingshausen Sea has actually migrated to the Ross Sea and reflects the large changes in the physical characteristics of the ice cover in this region. www.lighthouse-foundation.org /lighthouse-foundation.org/eng/maproom/bellings_sea.shtml   (417 words)

S.O.-Field Study Summary and Recommendations The Bellingshausen Sea is a region where relatively discrete populations of krill and other holozooplankton might be maintained, by virtue of a regional gyral circulation, which may restrict communication with adjacent seas. Relatively little information exists on plankton distributions in the Bellingshausen Sea, although the nearby waters of the Antarctic Peninsula region are perhaps the best studied in all the Southern Ocean. This is particularly important because waters from the Bellingshausen Sea provide some of the flow through the northern reaches of the Antarctic Peninsula coastal region, and thus the fauna of the Bellingshausen are already reasonably well known. www.usglobec.org /reports/so/so.chapter2.html   (2644 words)

The Antarctic Ocean floor The biodiversity of the seas and the ocean floors is a mystery for science yet to unravel. With this curiosity, a research team — including a biologist from the University of the Basque Country, is to set sail for the second time on an oceanographic campaign to study this biodiversity of the seas and the ocean floors of the Antarctic. With the Agassiz-trawl a corridor of the sea floor is swept to catch all the species on the way in a mixed form. www.eurekalert.org /pub_releases/2005-09/ef-tao090205.php   (473 words)

Within these sectors, higher sea level pressure, warmer air temperature and warmer sea surface temperature are generally associated with El Niño. Examples include a record decrease in sea ice coverage in the Bellingshausen Sea from mid-1982 through early 1999; the reduced sea ice concentration in the Ross Sea; and the shortening of the ice season in the eastern Ross, Amundsen and far western Weddell Seas. www.usatoday.com /news/science/cold-science/2002-03-06-nino-ice.htm   (423 words)

CONCLUSIONS   (Site not responding. Last check: 2007-11-02) Supposing that sea-ice coverage within the Antarctic Zone was the main factor controlling biological productivity in the Bellingshausen Sea, and thus the estimated opal depositional rates on the continental rise, we reconstructed paleoceanographic long-term changes during the Neogene and Quaternary considering the climatic control on regional and on global scales. During the late Miocene, temperatures in the Bellingshausen Sea as well as in the Atlantic sector of the Southern Ocean were slightly warmer than at present. A strong productivity increase in the Bellingshausen Sea before the closure of the Panama Isthmus might indicate that initial strengthening in NCW flow reported at ~5 Ma was at least partly triggered by early warming in Antarctica and the adjacent Southern Ocean. www-odp.tamu.edu /publications/178_SR/chap_23/c23_6.htm   (490 words)

Autosub Under Ice | Funded projects   (Site not responding. Last check: 2007-11-02) Sea ice is a key component of the climate system, as its thickness directly affects the amount of heat transferred from the ocean to the atmosphere. We will analyse sea ice thickness data collected with this sensor in the Bellingshausen Sea. Whilst the AUV is deployed, a series of sea ice thickness measurements with a drill will be made to ground-truth the swath data. www.soc.soton.ac.uk /aui/brandon.html   (189 words)

[No title]   (Site not responding. Last check: 2007-11-02) The thickness distribution of sea ice and snow cover during late winter in the Bellingshausen and Amundsen Seas Data collected from a voyage of RV Nathaniel B. Palmer to the Bellingshausen and Amundsen Seas during August- September 1993 are used to investigate the thickness distribution of sea ice and snow cover, and the processes that influence the development of the first year pack ice. The data are a combination of in situ and ship-based measurements, and show that the process of floe thickening is highly dependent on ice deformation; in particular rafting and ridging play important roles at different stages of floe development. www.agu.org /pubs/abs/jc/96JC02737/tmp.html   (325 words)

SCAR » Workshop Report, Fairbanks, 2004 This seems to be associated with a decrease in sea ice over the Bellingshausen Sea, although it is not clear why this has taken place. The largest error was overly deep surface pressure over the Bellingshausen Sea, which resulted in excessively strong northerly winds to the west of the Peninsula, giving too little sea ice. The importance of observations of sea ice thickness was raised. www.scar.org /researchgroups/physicalscience/fairbanks04   (4562 words)
