Location

edit
 
Davis Coast, Antarctic Peninsula. Curtiss Bay at the southwest end

Lanchester Bay is on the Davis Coast on the west side of the Antarctic Peninsula. It opens onto Orléans Strait to the northwest. Wright Ice Piedmont is to the southwest, the Detroit Plateau to the southeast and Sabine Glacier to the northeast.[2]

Mapping and name

edit

Lanchester Bay was photographed by Hunting Aerosurveys in 1955–57 and mapped from these photos by the Falkland Islands Dependencies Survey (FIDS). It was named by the UK Antarctic Place-Names Committee (UK-APC) in 1960 for Frederick W. Lanchester (1868-1946),, an aeronautical engineer who laid the foundations of modern airfoil theory.[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.
