Desudava Glacier (64°26′50″S 60°10′00″W) is the 15.5 kilometres (9.6 mi) long and 5 kilometres (3.1 mi) wide glacier on Nordenskjöld Coast in Graham Land, Antarctica situated south of Dinsmoor Glacier and east-northeast of Boryana Glacier.^[1]

Location

Nordenskjöld Coast, Antarctic Peninsula. Odrin Bay in center

Desudava Glacier is on the Nordenskjöld Coast of the Antarctic Peninsula. It is southeast of the Detroit Plateau and north of the Weddell Sea.^[2] It is drains the northeast slopes of Gusla Peak and adjacent slopes of Detroit Plateau further north, the south slopes of Ivats Peak and the west slopes of Mount Elliott, and flows southwards into Mundraga Bay next east of Boryana Glacier.^[1]

Name

Desudava Glacier is named after the ancient Thracian town of Desudava in southwestern Bulgaria.^[1]

Storgozia Nunatak

64°27′58″S 60°08′28″W. A rocky hill rising to 593 metres (1,946 ft)^[11] high in eastern Desudava Glacier. Situated 8.65 kilometres (5.37 mi) east of Rice Bastion, 6.1 kilometres (3.8 mi) southeast of Gusla Peak, and 2.8 kilometres (1.7 mi) south-southwest of Zgorigrad Nunatak. Named after the ancient town of Storgozia in Northern Bulgaria.^[12]

Rice Bastion

64°27′S 60°19′W. A substantial mountain mass surmounted by a small crown of exposed rock which appears slightly higher than the plateau behind it, projecting from the edge of Detroit Plateau, 8 nautical miles (15 km; 9.2 mi) southwest of Mount Elliott. Mapped from surveys by the Falkland Islands Dependencies Survey (FIDS) (1960-61). Named by the UK Antarctic Place-Names Committee (UK-APC) for Lee Rice, FIDS surveyor at Hope Bay (1957-58), who worked in this area.^[13]

It drains the southeast slopes of Detroit Plateau, flowing between Rice Bastion and Gusla Peak, and turning southwards to enter Mundraga Bay between Desudava Glacier and Darvari Glacier. Named after the settlement of Boryana in Northeastern Bulgaria.^[14]

Darvari Glacier

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.
