The dynamics of the Brunt Ice Shelf, Coats Land, Antarctica British Antarctic Survey Scientific Reports, 79,Track of Endurance. A non‐hydrostatic numerical weather prediction model has been employed to simulate idealized katabatic flows over a moderate slope and adjoining ice shelf.

The topography of Coats Land and the adjoining Brunt Ice Shelf, Antarctica, has been used; this is typical of much of the Antarctic by: the cooling of the ice shelf boundary layer leads to an apparent retreat of the katabatic ow from the ice shelf and some way up the slope.

The dynamical analysis explains the surface climatology observed, such that the persistent katabatic winds of Coats Land rarely reach the Brunt Ice Shelf.

Thomas. Introduction [2] Much of the Antarctic coastline is fringed by floating ice shelves which range in area up tokm 2 (e.g. Ross and Filchner‐Ronne ice shelves) and in thickness up to 2 km or more [Doake et al., ].Although they are large bodies of ice, vertical tidal flexure in the grounding zone has been measured and modelled by elastic‐type bending [Vaughan, ].Cited by: Coats Land consists of the Brunt Ice Shelf and the adjoining continent to the south.

The topography of this region is typical of much of the Antarctic coastal fringes: a modest slope. The Brunt Coats Land shelf is an area of floating ice bordering the Coats Land coast in the Weddell Sea sector of Antarctica. This Copernicus Sentinel-2 image from 7 February shows two lengthening fractures: a large chasm running northwards and a split, dubbed Halloween Crack, that has been extending eastwards since October 10 The grounding Coats Land between the Brunt Ice Shelf and the grounded ice in Coats Land is steep and heavily crevassed, so that the entire ice sheet breaks up into large blocks.

Therefore, the majority of the inner part of the Brunt Ice Shelf actually comprises icebergs surrounded by sea ice and has dynamics of the Brunt Ice Shelf topographic relief (Fig.

Dynamics of the Brunt Ice Shelf, Coats Land, Antarctica. London: British Antarctic Survey, The Brunt Ice Shelf borders the Antarctic coast of Coats Land between Dawson-Lambton Glacier and Stancomb-Wills Glacier Tongue.

It was named by the UK Antarctic Place-names Committee after David Brunt, British meteorologist, Physical Secretary of the Royal Society, –57, who was responsible for the initiation of the Royal Society Expedition to this ice. On the Brunt Ice Shelf, the rotation of the ice shelf mentioned by Thomas and Hulbe et al.

is well captured, and the center of rotation of the ice shelf is indeed located between rifts 2 and 3. Overall, the new model successfully replicates the modeled velocities across rifts, which is especially difficult given the gradients across each by: 5.

Ice shelves are in constant motion from the rising tides, splitting off icebergs in a soupy mélange of icebergs and snow ice at its edges The ice shelf can grow again as inland glaciers feed it.

If ice shelves did not form during retreat then the analysis indicates that most of the West Antarctic Ice Sheet would have collapsed by yr B.P. Thus, the present-day Ross Ice Shelf (and probably the Ronne Ice Shelf) serves to stabilize the West Antarctic Ice Sheet, which would collapse very rapidly if the ice shelves were removed.

This paper reviews several mechanisms whereby calving of icebergs may occur. An ice-shelf or ice-tongue may fracture in a number of locations, evidently in all cases, primarily as a result of the induction of a bending moment superimposed on the normal expansive creep of the floating slab.

Position fi xes made at the British Antarctic Survey station, Hall ey, on the Brunt Ice Shelf are considered for the period Coats Land, region of Antarctica bordering the southeastern shore of the Weddell Sea.

It extends about miles ( km) from Filchner Ice Shelf (southwest) to Queen Maud Land (east) and includes the coasts of Luitpold and Caird.

It was discovered in by the Scottish explorer William Speirs Bruce while on an investigation of the Weddell Sea and was named for the. Brunt Ice Shelf. This Antarctic ice shelf on the eastern side of the Weddell Sea is a fringing ice shelf (i.e.

not embayed), and is fed by ice flowing from Dronning Maud Land, including the quite active Stancomb Wills Glacier flowing into its eastern by: The British Antarctic Survey's Halley Research Station is located on the Brunt Ice Shelf, Antarctica, where it is potentially vulnerable to calving events.

Existing historical records show that the Brunt Ice Shelf is currently extended further into the Weddell Sea than it was before its last large calving event, so a new calving event may be. been used to simulate several case studies of katabatic wind situations in Coats Land, Antarctica.

This region is located on the eastern shore of the Weddell Sea, and consists of the Brunt Ice Shelf and the adjoining continent to the south.

Slopes are modest (5% at most), and katabatic winds are moderate (typically observed.

Antarctica. The Brunt Ice Shelf system is situated on the Caird Coast on the western shore of the Weddell Sea. It is part of an almost continuous fringing ice shelf along the coast of Coats Land and Dronning Maud Land in East Antarctica.

The Brunt Ice Shelf system consists of the Brunt Ice Shelf (BIS) and adjacent Stancomb-Wills Ice Tongue (SWIT).Cited by: 6. Antarctica - June 30th, Coats Land is a region in Antarctica which lies westward of Queen Maud Land and forms the eastern shore of the Weddell Sea.

The Brunt Ice Shelf, visible here, borders the Antarctic coast of Coats Land, Antarctica, between the Dawson-Lambton Glacier and the Stancomb-Wills Glacier Tongue.

Bases that are built in such places therefore become slowly buried in the snow and ice. They can also be carried towards the coast if they are sitting on a moving ice shelf.

Halley Station is located on the Brunt Ice Shelf at 75°35'S, 26°34'W. Inthe same year that Filchner became operational, the British Antarctic Survey (BAS) had constructed and opened the third replacement of Halley Station (Halley IV) about kilometers from Filchner, on the Brunt Ice Shelf off of Coats Land.

The site conditions on the Brunt Ice Shelf were severe. The Brunt ice shelf is an area of floating ice bordering the Coats Land coast in the Weddell Sea sector of Antarctica.
