Cugnot Ice Piedmont (63°38′S 58°10′W / 63.633°S 58.167°W / -63.633; -58.167 (Cugnot Ice Piedmont)) is an ice piedmont in Trinity Peninsula, Antarctica. It is about 15 nautical miles (28 km; 17 mi) long and between 3 and 6 nautical miles (5.6 and 11.1 km; 3.5 and 6.9 mi) wide, extending from Russell East Glacier to Eyrie Bay and bounded on the landward side by Louis Philippe Plateau.[1]

Location

[edit]
Trinity Peninsula, Antarctic Peninsula. Cugnot Ice Piedmont in center of southeast coast

Cugnot Ice Piedmont is in Graham Land in the center of the south coast of the Trinity Peninsula, which forms the tip of the Antarctic Peninsula. It is on the coast of the Prince Gustav Channel to the south of the Louis Philippe Plateau and Broad Valley. Eyre Bay is to the northeast and Russell East Glacier is to the southwest. Features, from west to east, include Benz Pass, Panhard Nunatak, Levassor Nunatak, Chapel Hill, Shelter Cove, Church Point, Striped Hill, Camp Hill, McCalman Peak, Crystal Hill, Bald Head and Jade Point.[2][3]

Exploration and name

[edit]

Cugnot Ice Piedmont was mapped from surveys by the Falkland Islands Dependencies Survey (FIDS; 1960–61), and was named by the UK Antarctic Place-Names Committee (UK-APC) for Nicolas-Joseph Cugnot (1725-1804), a French military engineer who designed and built the first full-sized vehicle propelled by its own engine (steam), in 1769.[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.
