AbstractSLAR imagery of Nares Strait was obtained on three flights carried out in. January, March, and August of 1973 by Canadian Forces Maritime Proving and Evaluation Unit in an Argus aircraft equipped with a Motorola APS-94D SLAR; the March flight also covered two lines in the Arctic Ocean, from Alert 10 the North Pole and from the Pole down the long. 4ºE. meridian to the ice edge at about lat. 80º N. No observations on the ground were possible, but -some back-up was available on all flights from visual observations recorded in the air, and on the March flight from infrared line-scan and vertical photography.The interpretation of ice features from the SLAR imagery is discussed, and the conclusion reached that in spite of certain ambiguities the technique has great potential which will increase with improving resolution, Extent of coverage per distance flown and independence of light and cloud conditions make it unique among airborne sensors.

Frederick George Jackson, the leader of the Jackson-Harmsworth Expedition of 1894–1897, accomplished a great deal during his exploration of Franz Josef Land [Zemlya Frantsa-Iosifa] although his achievements have never been fully acknowledged. Jackson's expedition itself has often been eclipsed by his famous meeting in 1896 with Fridtjof Nansen, absent for 3 years in the Arctic and it has been unfairly coloured by the view that Jackson was no more than an adventurer and sportsman. The research reported in this article evaluates Jackson's plan and management activities. The study developed a set of factors to evaluate his performance arising from a variety of expeditions contemporary with Jackson's. His strong personality and limited personnel managerial experience limited the full extent of what he might have achieved. Yet, Jackson developed a strong exploration model that was based on comprehensive planning, a significant concern for the health and welfare of his companions, the willingness to innovate in a number of activities including sledging, and a commitment to scientific discovery. Although the expedition did not find a route to the North Pole, Jackson confirmed that Franz Josef Land was an archipelago and he gave credence to the consumption of fresh meat as a means of preventing scurvy. One of Jackson's legacies to subsequent explorers was the use of ponies for haulage. He was unable to appreciate the weaknesses in their use and his influence on subsequent Antarctic expeditions often led to undesirable results. But, overall, Jackson was an innovator in a conservative exploration community.

Russian foreign policy in the increasingly important Arctic region reflects an ambiguous combination of assertiveness and cooperation in accordance with international law. Against this background, the existing literature on the Arctic tends to polarise around revisionist and status quo interpretations of Russian foreign policy in the region. The present paper contrasts the divergent interpretations through case studies of the Russian flag planting on the North Pole seabed in 2007 and Russia’s participation at the Ilulissat Summit in 2008 which can be seen as ‘crucial’ cases for the competing interpretations. Overall, the case studies provide support for a modidied version of the status quo interpretation which incorporates insights from the revisionist interpretation.

About 4000 years ago the first immigration of Inuit tribes explorated Greenland, and about 1000 years ago the Norsemen explorated southwest Greenland; and Icelandic sagas describe every-day life. The early search for the Northwest Passage years ago was followed by intensive whaling during 17th and 18th centuries. The connection between Greenland and Scandinavia was re-established by Hans Egede, who started his missionary and explorationary activity in 1721, whereafter polymaths from Denmark and other countries contributed to our scientific knowledge. Several attempts to reach the North Pole resulted in new information about the High Arctic Greenland, while local Inuit, such as Hans Hendrik, played an important role in several expeditions in the Arctic. The growing Danish and foreign scientific expeditions led to the Danish government establishing in 1878 established the Commission for Scientific Research in Greenland, whose mandate was to coordinate such research.
