The Arctic Institute of North America is concerned with the prosecution of research in the arctic and subarctic regions of the North American continent and in Greenland. The United States, Canada, and Greenland are represented on its Board of Governors. In the ten years during which the Institute has functioned, it has financed, or helped to finance, 177 projects of research in these northern areas, in a great variety of fields of scientific endeavour. In so doing, it has assisted in building up a corps of younger scientists competent to work in arctic territory. From these younger men much will be expected in the future. For the need is great. There are other agencies that are responsible for research work in the far north-governmental departments, private corporations, industrial firms. But the Arctic Institute of North America is the only agency that is international in scope. It deals with the problems in their wider scientific importance, unimpeded by national boundaries. Not only is this in the best interests of science; it is also in the best interests of international cooperation. There are common problems of defence in which this northern territory plays a very significant part. Because of this fact, a part of the research work in the Arctic in recent years is on the classified list, and does not appear in the current publications. It is none the less of great importance both from the scientific standpoint and in the national interest. The Research Committee of the Arctic Institute felt that a review of the present status of arctic research in the various fields of science would now be of value both to the scientific worker and to others who are interested in northern development. It was suggested that there would be great value if the present trends and the future needs were emphasized. The Committee has been fortunate in securing the cooperation of highly competent authorities in the sciences that are represented in this volume. The reader will be impressed with the work that has been accomplished. He will be even more impressed with what yet has to be done. The territory is very large. Much of it is not easily accessible. The season in summer is short. The work is arduous and demands special training. The workers are relatively few. This volume will have served its purpose if it stimulates to more widespread activity in arctic research. What has already been done has added greatly to our knowledge of the Arctic. It has done more; it has made the Arctic more accessible to those who are engaged in the development of its resources, and in the well-being of its people. The Arctic Institute of North America has already played no inconsiderable part in the encouragement of arctic research. Governmental departments, corporations, and private individuals have assisted the Institute greatly in their work. It is a great pleasure to take this opportunity to express the appreciation of all who are associated with the Institute for the support which has been given so generously. It is the hope of the Governors that, with still wider support, much can be accomplished that the authors of the papers in this volume feel is so urgently needed to be done.

Arctic, v. 7, no. 3 and 4, 1954, p. 188-190
ASTIS record 9745
PDF

Contains review of communication problems in northern Canada. Shortwave radio via sky-wave tranmission is the most economical method of communication, but suffers from occasional failures due to ionospheric disturbances. Ionospheric research conducted in Canada to improve short-wave radio is discussed. Eight ionospheric recording observatories were established. Four of these, at St. John's in Newfoundland, Ottawa, Winnipeg, and Prince Rupert, skirted the southern part of the auroral zone from east to west. Stations at Churchill and Fort Chimo were near the line of maximum auroral occurrence, and those at Baker Lake and Resolute Bay extended the line of observations from Winnipeg to a point north of the magnetic pole. In 1954 the stations at St. John's, Fort Chimo, and Prince Rupert were discontinued. Research on spectra, luminosity, height, and electron density of the aurora is briefly discussed.

Arctic work of the Canadian Geodetic Survey started in 1935. Between 1942 and 1950, 300 astronomical stations were established on the mainland north of the tree-line and in the southern Canadian Arctic Islands. The shoran electronic method of position fixation has superseded the astronomical method in most areas. Methods are described, as is the extension of the Canadian shoran net since 1949. Future extensions, gravity observations, and needed investigations of changes in mean sea level are briefly discussed.


Oceanographic problems of the Arctic Ocean   /   Iselin, C.O'D.
Arctic, v. 7, no. 3 and 4, 1954, p. 195-198
ASTIS record 9747
PDF

General physical, biological and geological characteristics of the Arctic Ocean are known, but circulation requires investigation. Only here does it occur to considerable depths without a significant supply of energy from local winds. Influence on it of bottom topography is confirmed by knowledge of the recently discovered Lomonosov Ridge, dividing the Basin in two. Advantages of this area for oceanographic study are the comparatively (to other oceans) small size, and a working platform provided by the ice; need is stated for aircraft designed specifically for arctic oceanography.

Knowledge of tidal conditions is meager and observations are difficult to obtain because of the prevalence of ice, scarcity of inhabited areas, and inaccessibility of the region. Stations are noted with data available for Canadian Arctic Islands waters, arctic coast of Alaska, Hudson Bay and Strait, Baffin Bay-Davis Strait, and east coast of Greenland. Additional stations, long-period observations depth soundings, new techniques are stated to be necessary.

Distribution of arctic lakes is noted and the literature reviewed. General problems in arctic limnology include thermal and trophic classifications, water circulation, productivity as compared with arctic marine waters, and comparison of arctic and alpine lakes. Future research programs should comprise a reconnaissance of lakes in the Canadian Arctic, intensive investigation of selected lakes and a river, expansion of Ungava work and general studies on distribution of fresh-water fish. Cooperation between limnologists, plant ecologists, and geologists is urged.
