Deglaciation and emergence of the Webb Bay – Port Manvers run area of Labrador.

Johnson, John. P. January 1964 (has links)
Labrador's coastal scenery is dominated by evidence of Pleistocene glaciation. Before World War II only a few, generally bread studies touching on this subject bad been made in Labrador. From these the overwhelming effect of continental glaciation became clear. However, the chronology of glaciation had yet to be established, and little regional evidence bad been obtained to support existing hypotheses explaining the character and effects of Labrador-Quebec's glaciation. Expeditions like that of Vainö Tanner (1944) have shown that studies in detail or concentrated in small areas are essential if the deglaciation and emergence of coastal Labrador are to be understood.

Rainfall evaporation and sugar cane yields in Barbados.

Oguntoyinbo, Julius S. January 1964 (has links)
Sugar cane has been the mainstay of the economy of Barbados since 1645 and it has, in spite of the vicissitudes of the sugar industry, maintained this unique position ever since; this can be realised from the fact that it contributes over 90 per cent of the annual income of the island (Macpherson, 1963, p. 75). The predominance of this crop has led to great interest being taken in measures by which a potential yield can be attained. The potential yield, according to Dillewijn (1952, p. xxii), is the maximum yield attainable given that the following five factors are fully satisfied: solar energy (heat and light), moisture (rainfall and irrigation), soil condition, availability of labour, and cultural methods. The potential yield, he states, is only of theoretical importance because the sugar industry is an economic enterprise, concerned with economic yield, which is generally lower than the potential yield.

Observations of glacier termini in the Prince William Sound area, Alaska.

Millett, Marion T. January 1965 (has links)
Since Captain James Cook's historic voyage in 1778, Alaskan glaciers have been described, mapped, and studied many times. Several expeditions have gone to Alaska for the sole purpose of studying glaciers. Of these field studies the most important were the Harriman Alaska Expedition of 1899 (Gilbert, 1903), the National Geographic Society's Alaskan Expeditions 1909, 1910 (Tarr and Martin, 1914), and the work of William O Field in 1931 and 1935 (Field, 1932 and 1937).

Lower Yuna river basin domincan republic restraints on agricultural development posed by physical and land tenure problems.

McEachern, John D. January 1966 (has links)
The findings of this study are primarily based upon fieldwork, for the reason that only scanty written sources exist on the Lower Yuna. This dearth of background information on which to build sometimes results in an unsophisticated level of treatment and has made necessary the inclusion of substantial descriptive and explanatory material in the form of expanded footnotes.

The post-champlain evolution of the drainage pattern of the Montreal lowland.

Macpherson, Joyce Constance. January 1966 (has links)
The St. Lawrence River is one of the youngest of the world's great rivers. Much of its course below Lake Ontario traverses the floor of the Champlain Sea, a late-glacial marine embayment which flooded the lowland between the Canadian Shield and the Appalachian highland. [...]

An isochronic study for Winnipeg and Montreal; peripheral and intervening areas.

Paterson, Laurie Andrée. January 1951 (has links)
The definition: An isochrone is a line connecting all the points equally distant in time from a given centre. (Gr. isos equal + chronos time). The purpose of the study: The purpose of this isochronic study is to determine the patterns of relative accessibility centred on the two cities of Winnipeg and Montreal. [...]

Vegetation and Physiography of the Goose Bay Area, Labrador: and the Interpretation of Forest Cover Types and Landforms from Aerial Photographs.

Blake, Weston. January 1953 (has links)
Most of the peninsula of Labrador-Ungava is within the belt of coniferous forests which extends around the world in northern latitudes, and the present study is on the forests and physiography around Goose Bay, Labrador, an area which has come into recent focus as the site of an important air base. This area, together with almost all of the rest of Canada, has been photographed from the air in recent years, and this has created a tremendous store of material which was formerly unavailable to the research worker due to the difficulty of travelling through the interior of this rough and sparsely settled country. Naturally, aerial photographs are of great value to scientists in various fields, and many projects are under way using this new source of information.

The dissolution of the West Indies federation: a study in political geography.

Lusaka, Paul Firmino. January 1964 (has links)
The rapidity with which important developments are occuring in West Indian affairs makes it impossible to be up to date with everything in this work. What is more, since many parts of the West Indies lag behind in the publication of statistics it has been impossible to obtain reasonably complete sets of figures, for example, statistical data on population densities for a year or two preceding the formation of the Federation (1958); which means that some data are a few years old at the time of writing.

L’aménagement des villes á industrie extractive du subarctique.

Langlois, Jean-Claude. January 1957 (has links)
L’aménagement des villes á industrie extractive dans la zone subarctique amène des problèmes complexes. Ces agglomérations urbaines, liéees á l'industrie minière, forestière, pétrolière ou hydro-électrique affichent des caractères personnels qui les identifient. Si leurs caractères, leurs raisons d'être, leur administration et leur gouvernement municipal et leur législation diffèrent dans les diverses parties du Canada, elles présentent toutefois les mêmes grands problèmes. La province de Québec offre en Schefferville, Chibougamau et Chapais trois exemples de ces villes minières subarctiques. L'étude de leur milieu géographique fait ressortir les problèmes á résoudre dans leur aménagement.
