Forest types of the Kenamu-Kenemich drainage basin, Labrador: an interpretation of cover types from an aerial photograph mosaic.

McKay, Ian. A. January 1956 (has links)
The Labrador-Ungava Peninsula, until post-war years relatively unknown, has taken on a new significance recently due to the development of vast iron ore deposits and the present threat to world peace. Since the war, the Goose Bay Air Base, carved out of the wilderness, has made Labrador the front entrance to Canada for many who arrive here from abroad. In 1954, since this study was begun, the author had the pleasure of opening the McGill Sub-Arctic Research Building at Knob Lake which will act as a centre for field research into this remote area.

Development of slopes in central New Quebec-Labrador.

Twidale, Charles. R. January 1957 (has links)
Central New Quebec-Labrador represents a virtually virgin field to the geomorphologist and such is the variety of physiographic problem awaiting investigation that there is an almost unlimited choice of research topic. A concentration of activity is essential if worthwhile results are to be forthcoming, largely because of the relative brevity of the (summer) field season, but also on account of the considerable difficulty of traversing much of the terrain. Of the uninvestigated physiographic problems, the present writer chose to undertake a study of the morphology and genesis of hillslopes.

Evapotranspiration at Point Barrow, Alaska, summer 1956.

Shellabear, William. H. January 1959 (has links)
Barrow is the most northern First-Order Weather Station operated by the U.S. Weather Bureau. Much of the data that will be mentioned here has been taken from the "Local Climatological Data" for this station. Normal values are based upon the period of 1921-1950. These forms are published monthly by the U.S. Department of Commerce, Weather Bureau.

Meteorological Observations on the Chamberlin Glacier; Brooks Range, Arctic Alaska, Summer 1958.

Larsson, Peter. January 1960 (has links)
A preliminary investigation of the meteorological conditions on the Chamberlin Glacier in the summer of 1958 was carried out, with emphasis being placed on the measurement of some of the parameters needed to assess the energy balance of the glacier. The Expedition was not equipped with the instruments necessary to carry out a detailed micro climatological study, thus no quantitative measurements of heat balance were obtained. [...]

Glacial geomorphology in the Kaumajet mountain and Okak Bay areas of North Eastern Labrador.

Tomlinson, Roger. F. January 1961 (has links)
Arguments concerning the nature and extent of the North American glaciation as a whole, and that of Labrador in particular, have been regularly appearing in print from 1883 until 1959. From the theories and reports presented it is possible to draw together several distinct lines of thought. Early work by Bell (1882-84), Daly (1902), and Coleman (1921) suggested that the higher parts of the eastern edge of north east America had not been covered by continental ice. Coleman goes as far as to say that in the Nachvak area, “the unglaciated condition is known to reach at least 50 miles inland, giving a driftless area of perhaps 3,000 or 4,000 square miles”, though he concedes that valley glaciers must have reached the sea in areas to the south of Nachvak.

Deglaciation and postglacial emergence of Northernmost Labrador.

Löken, Olav. H. January 1962 (has links)
Northern Labrador lies within the Canadian Shield, its bedrock being generally Precambrian in age or, more accurately, Archean in the area covered by this study. (Map 2) (Piloski 1954). Highly metamorphosed paragneisses and gneisses of granitic composition are the major rock-types, but granite and quartzites occur as well. The bedrock is generally coarse grained and weathered into a very rough surface, on which striae are usually absent. In the areas of gneiss, the local variation in petrography is large, as quartz-inclusions and inclusions of granites are numerous (Ill. 80). Because of this, the identification of erratics is extremely difficult, and in no case was the source-area of a suspected erratic boulder determined.

The moisture balance of Barbados and its influence on sugar cane yield.

Rouse, Wayne. R. January 1962 (has links)
Barbados has the distinction of a one crop economy, that crop being sugar cane. This situation has existed for over 500 years, and during the latter part of this period, particularly since 1924, the cane breeding section of the Department of Agriculture has carried on extensive work in developing high yielding varieties of sugar cane especially suited to the island. The nature of investigation has, however, being virtually confined to this one direction, and study of the other important growth factors such as edaphic and especially climatic control has lagged far behind. Fortunately in 1959 a microclimatic station was set up at Waterford under the auspices of the Geography Department of McGill University, and in the last 2 years a considerable knowledge of various climatic parameters has been amassed, and an insight into the moisture balance regime achieved.

The physiography of Melville Penisula, N. W. T.

Sim, Victor. W. January 1962 (has links)
Melville Peninsula is the largest and most easterly of several peninsulas which extend northward from the eastern mainland portion of the Northwest Territories in the Canadian Arctic. It has a maximum. north-south length of approximately 250 miles (66° 10’N. to 69°52'N.) and a. maximum width at its widest point of approximately 140 miles (81°15’W. to 86°36’W.). The peninsula, itself within the District of Franklin, is joined to the northeastern corner of the District of Keewatin by Rae Isthmus. It forms the western shore of Foxe Basin (map 1) and is separated from Baffin Island to the north by Fury and Hecla Strait and from Southampton Island to the south by Frozen Strait. The region covered by this study includes Wales, Amherst and Igloolik Islands. It does not include several smaller islands off the extreme southern tip of the peninsula.

Post-glacial fluctuations of sea level around north-east Brodeur peninsula, Baffin Island.

Compton, Paul. A. January 1963 (has links)
For many years evidence has been accumulating from the Canadian Arctic that changes have taken place in the relative level of land and sea incidental to the growth and dispersion of the Pleistocene ice sheets. The effect of this glaciation was two-fold. The growth of the ice sheets led to a depression of the earth’s crust beneath the glaciated areas and to also resulted in a world-wide lowering of sea level, while the disappearance of the continental ice sheets resulted in an eustatic rise of sea level and an isostatic uplift of the depressed land areas. Flint estimates that the eustatic lowering of sea level during the last glacial maximum was approximately 350 feet.

The geomorphology of Ceylon a study of tropical terrain based on aerial photographs.

Erb, David. K. January 1963 (has links)
The geology of Ceylon, as it applies to this study, is basic in concept. The most important factors being the resistance of the rocks to weathering and erosion, and the tectonic activity, both local and regional, to which they have been subjected. These are the factors which, under the tropical conditions obtaining, control to a large extent the development of the various landforms characteristic of the area. In general, the views outlined are those at present accepted by the geologists working in the area. No radically new ideas with respect to rock type, lithologies, or stratigraphic sequences are presented. Much of the tectonic history however has been deduced from photogeomorphologic evidence and may not agree entirely with presently held views.
