Sir, Glaciological observations in north-central Greenland
During early July 1966 we were fortunate in being able to visit “Inge Lehman” station, a camp established by the Arctic Institute of North America and the U.S. Air Force, on the Greenland ice sheet. Our purpose was to test small-scale traverse techniques using Bombardier “Ski-dons” and to make snow studies south-east of the station in an area hitherto unstudied. We also intended, if possible, to locate “Northice”, the 1952–54 ice-sheet station of the British North Greenland Expedition, and obtain snow accumulation and deformation measurements. Because of changes in flight schedules, the traverse to the south-east, which was intended to be approximately 160 km in length, had to be shortened to 28 km. “Northice” was revisited and a series of measurements were made. Figure 1 shows “Northice” on 4 July 1966 and can be compared with Reference BanksBanks ([c1957], p. 128) and Reference SimpsonSimpson (1957, p. 213, 220). The following are the results of the measurements:
Station | Latitude | Longitude | Elevation | 1956–65 accumalation rate | 10-m temperature |
---|---|---|---|---|---|
m | g cm−2 year−1 | ° C | |||
“Northice” | 78° 04.3′ N. | 38° 29.3′ W. | 2 345 | 10.4 | |
“Inge Lehman” station | 77° 56′ N. | 39° 11′ W. | 2 407 | −30.4 | |
“Station 1” | 77° 43′ N. | 38° 40′ W. | 2 431 | 10.5 | −31.3 |
