Geological investigations in Ellesmere Island, 1952   /   Troelsen, J.C.
Arctic, v. 5, no. 4, Dec. 1952, p. 198-210, ill., figures
ASTIS record 9712

Contains an account of the author's studies of the Canyon Fjord region (ca. 80 N, 82 W), especially of Caledonian Bay, east of Eureka in summer of 1952. Studies of the Ellesmere Island mountains; and previous expeditions to Canyon Fjord are noted; the author's itinerary and his geological investigations are reported, proving the essential correctness of Lauge Koch's early contention that the mountains of North Greenland and Ellesmere Island are of the Caledonian age; author's collecting of plants and microfauna, observations on animals (muskox, hare, fox wolf, seals, birds) are mentioned. Bibliography (4 items).

"T3 is an ice island in the Arctic Ocean on which a permanent campsite was erected in 1952 for scientific operations. The investigations, other than meteorological, in progress from April 1-Oct. 1, included studies of the physical structure of the island, the movement of the island and the ice pack, seismic profiling and other miscellaneous data. T3 is 31 mi in circumference and has a minimum width of 5 mi. A 52-ft hole was dug in which 58 dirt layers were found, the contents of which were weighed and microscopically examined. Lakes appeared in the hollows during the thaw period (late June to mid-Aug.). A map presents the track of T3, indicating the changes of island azimuth to true and magnetic north and the geographical longitudes. A tentative ice thickness of about 160 ft was obtained through seismic soundings of the ice and the ocean bottom. Ocean depths ranging from 5000-12,000 ft were obtained."--SIPRE. Samples of surface dirt, flora and fauna were collected, including large boulders of granitic rock, plant fragments (stems, leaves, blossoms), mollusc shells, fishbones, caribou antlers, etc. A few birds and bear and arctic fox tracks were seen. Continuing research on T-3 is indicated.

Identification of Petitot's Riviere La Ronciere-le Noury   /   Fraser, J.K.
Arctic, v. 5, no. 4, Dec. 1952, p. 224-234, ill., figures
ASTIS record 9709

Contains a study of explorations in the Horton and Hornaday River regions of northern Mackenzie District. Evidence is presented to suggest that the river discovered and mapped (excepting lower reaches) by the Oblate missionary Emile Petitot in 1868 is identical with the Hornaday. The latter, discovered by A.J. Stone in 1900 was explored only near its effluence into Darnley Bay. Recent mapping from aerial photographs show the source of the Hornaday (68 40 N, 120 20 W) and features of its course as similar to those recorded for La Ronciere-le Noury by Petitot in his Geographie de l'Athabaskaw-Mackenzie...1875.(Arctic Bibliography, No. 13406).

"Spekk-finger" or sealer's finger   /   Rodahl, K.
Arctic, v. 5, no. 4, Dec. 1952, p. 235-240, ill.
ASTIS record 9710

Contains an account of a severe local infection (cellulitis) common among sealers, especially those handling the blubber (spekk) or skins. Its occurrence and distribution, symptoms, cause (not as yet established, but probably Erysipelothrix rhusiopatiae), treatment, including latest experiment with antibiotics are discussed. Description of a case is given, and measures of prevention indicated. Bibliography (11 items).
