Measurements by SIPRE in 1955 on the accumulation markers of Expéditions Polaires Françaises in central Greenland
Benson, Carl S.; Ragle, Richard H.
Special ReportAbstract: Some of the activities of SIPRE's Expedition JELLO, which in part extended previous work done by Expeditions Polaires Francaises in central Greenland, are summarized. JELLO reached the French "Station Centrale" on 21 July 1955. The original station and deep pit (Puit Benoto) were visited; a 20-ft tower was erected; and all prominent markers were extended before JELLO departed on 1 August 1955. Expedition JELLO then followed the course westward that had been traversed by the French 4 and 5 years earlier, in an attempt to locate, measure, and lengthen the French accumulation markers which still showed above the 1955 snow surface. Fourteen of a possible nineteen or twenty markers were found. Measurements of the relative displacement of snow surface on the French markers over a 4-yr period (1951-1955), together with the 1-yr measurements (1950-1951) by the French, indicate a decrease in accumulation toward the higher elevations of the interior. This, in general, appears to check fairly well with stratigraphic observations in the snow, although the stratigraphic data have not been completely analyzed as yet.
