The Louis Philippe Plateau (63°36′S 58°21′W / 63.600°S 58.350°W / -63.600; -58.350 (Louis Philippe Plateau)) is a plateau, about 11 nautical miles (20 km; 13 mi) long and 5 nautical miles (9.3 km; 5.8 mi) wide, which rises to 1,370 metres (4,490 ft) and occupies the central part of Trinity Peninsula, Antarctica, between Russell West Glacier and Windy Gap.[1]

Location

[edit]
Trinity Peninsula, Antarctic Peninsula. Louis Philippe Plateau towards the southwest

The Louis Philippe Plateau is in Graham Land in the central spine of the Trinity Peninsula, which forms the tip of the Antarctic Peninsula. Marescot Ridge and Lafond Bay are to the north, Broad Valley and the Laclavère Plateau are to the east, the Cugnot Ice Piedmont and Russell East Glacier are to the south and Russell West Glacier and Srednogorie Heights are to the west. Features include Allen Knoll, Benz Pass, Windy Gap and Mount D'Urville.[2][3]

Name

[edit]

The name, recommended by the UK Antarctic Place-Names Committee (UK-APC) in 1948, commemorates Captain Jules Dumont d'Urville's 1838 exploration of the Trinity Peninsula area, which he had named "Terre Louis Philippe," after Louis Philippe I, the King of France at the time.[1]

REMA Explorer
The Reference Elevation Model of Antarctica (REMA) gives ice surface measurements of most of the continent. When a feature is ice-covered, the ice surface will differ from the underlying rock surface and will change over time. To see ice surface contours and elevation of a feature as of the last REMA update,
  • Open the Antarctic REMA Explorer
  • Enter the feature's coordinates in the box at the top left that says "Find address or place", then press enter
    The coordinates should be in DMS format, e.g. 65°05'03"S 64°01'02"W. If you only have degrees and minutes, you may not be able to locate the feature.
  • Hover over the icons at the left of the screen
  • Find "Hillshade" and click on that
    In the bottom right of the screen, set "Shading Factor" to 0 to get a clearer image
  • Find "Contour" and click on that
    In the "Contour properties" box, select Contour Interval = 1m
    You can zoom in and out to see the ice surface contours of the feature and nearby features
  • Find "Identify" and click on that
    Click the point where the contour lines seem to indicate the top of the feature
    The "Identify" box will appear to the top left. The Orthometric height is the elevation of the ice surface of the feature at this point.
