Glaciation of the Torngat Mountains, northern Labrador / Ives, J.D.
Arctic, v. 10, no. 2, 1957, p. 66-87, ill., map
ASTIS record 9797
Considers role of these mountains in glaciation of Labrador-Ungava, assessing particularly events in late-Wisconsin times with respect to final disappearance of both continental and local ice masses. Conflicting theories are discussed, and evidence presented, based on physiography and findings from summer 1956 field work, including unmistakable erratics on summits at 4,000-5,000 ft. The highest summits were completely submerged by eastward moving continental ice during the Wisconsin glaciation; local glaciers never reached significant dimensions; rapid melting in situ of thick masses of ice occurred during the final Wisconsin stages. Two or three separate glacial periods are recognized from the morphology of the area. Instantaneous glaciation of a large area of the Labrador-Ungava Plateau probably initiated a continental ice sheet in northeastern North America at the onset of each glacial period.

Ice fog as a problem of air pollution in the Arctic / Robinson, E. Thuman, W.C. Wiggins, E.J.
Arctic, v. 10, no. 2, 1957, p. 88-104, ill., figures
ASTIS record 9798
Extensive field programs were undertaken in Alaska during the winters of 1952-1954 to determine the causes of ice-fog formation. Ice fog forms at temperatures near -30 C and below in populated areas and is particularly troublesome at military installations. It poses no threat to health but seriously restricts visibility. The fog is a direct result of supersaturation of the cold air with water vapor from man-made sources. The only methods of curtailing its formation appear to be restricting vapor emission into the air or confining emission to selected fall stacks. Microphotographs of ice fog particles collected at various temperatures are included.
Development of young varying lemmings (Dicrostonyx) / Hansen, R.M.
Arctic, v. 10, no. 2, 1957, p. 105-117, ill.
ASTIS record 9799
An outline of growth and development of Dicrostonyx groenlandicus rubricatus from birth till the age of 40 days. Appearance of hair and teeth, motion, development of sense organs, weaning, appearance of defensive behavior and of sexual maturity are traced, and weight increase recorded. Observations were made on a laboratory colony established from specimens captured at Umiat, Alaska.
Greenland today / Brun, E.

ASTIS record 61058
... Greenland forms an integral part of the Danish kingdom, and its area of 780,000 square miles is about fifty times that of the rest of Denmark put together. ... Greenland is the largest island in the world, measuring from south to north more than 1,500 miles, but five-sixths of the area is covered by the vast ice cap, which has a thickness of up to 10,000 feet. Only a narrow coastal fringe is ice-free, and even there arctic conditions prevail and forests are non-existent. ... The 25,000 Greenlanders [0.5% of the total Danish population] who inhabit the coasts, in particular the southern part of the west coast, are of mixed Eskimo and Scandinavian extraction. The connection between Greenland and Scandinavia goes back a thousand years to the time of the Vikings .... The Greenlanders now all belong to the national Lutheran Church of Denmark, and in every respect enjoy equal status with other members of the Danish population. Politically, Greenland constitutes a part of the Danish democracy. Popularly elected local councils administer local affairs, and two Greenlanders, elected in Greenland, sit in the Folketing, the Danish Parliament. ... The economy of Greenland is based primarily on the sea. The land offers few facilities for economic development. ... The primitive economy was originally founded on seal-hunting, but the change in world climate, which has taken place during the last generation has forced the Greenlanders to reorganize their economic life as the seal vanished from southern Greenland waters and fish appeared to take its place. ... For nearly a hundred years the mineral cryolite, the bulk of which is used in the aluminium industry, has been mined at Ivigtut, in southwest Greenland. ... Since the war, an intensive geological survey of the whole of Greenland has been undertaken .... Greenland is remarkable for, among other things, the fact that there is no income tax - not yet! But there is other taxation, especially on spirits, tobacco, and various other luxuries. The revenue from these taxes goes to the local councils, which spend the bulk of it on social welfare, especially the care of the aged, invalids, orphans, etc. ... the Danish Government has assumed responsibility for the health services. The climate, and the poor housing that still exists in many places have meant that the health conditions in the past have not been good. Tuberculosis, in particular, has always been a scourge. ... The work of educating the people of Greenland began over two hundred years ago and it is a hundred years since illiteracy was abolished. ... there is at present a great deal of activity in adult education .... In a period that has seen the breaking-up of great colonial empires and the attaining of independence by former colonies, the opposite development has taken place in Greenland: a former colony has been integrated into the kingdom. ...
The cache at Victoria Harbour / Wright, N.
Arctic, v. 10, no. 2, 1957, p. 121-123, 1 map
ASTIS record 61061
This [cache] was established by Captain John Ross on May 28, 1832, just before the "Victory" was abandoned. In a "tunnel", the long and troublesome excavation of which is described in Chapter 48 of his "Narrative", he deposited the following valuable scientific instruments: one 36-inch transit, one 9-inch theodolite, one 3½-inch astronomical telescope, 5 feet 6 inches long, four chronometers, and also some gunpowder. Unfortunately, he never recorded the whereabouts of the tunnel! ... There are, however, two clues to the position of the cache, afforded by illustrations in the "Narrative". ... Of course, after 125 years it is more than possible that the site of the tunnel has been obliterated by landslides, but a skull has been found by an R.C.M.P. patrol from Spence Bay on the opposite side of the harbour, close to the mapped position of J. Dixon's grave [a seaman who died while the tunnel was being excavated], it may still be worth the while of any future visitors to Victoria Harbour to look on the eastern side of the harbour for John Ross's cache. ...
