AbstractDuring the monsoon of 1956 the Geological Survey of India sponsored an expedition to the Bara Shigri Glacier (lat. 32° 16′N., long. 77° 40′E), Kangra District, in the great Himalayan ranges of the Punjab, as part of the Indian programme for the International Geophysical Year 1956–57. Topographical maps of the terminal 3 miles of the glacier, on scales of 1:63.360 and 1:10,000, were prepared for comparison of morphological changes since it was last surveyed 50 years ago. The glacier appears to have shrunk considerably but its full extent could not be assessed because of insufficient earlier data. The Shigri Stream now emerges from a different part of the glacier snout. In order to assist future surveys three photographic stations were established.

ABSTRACTThe full extent of the height and scale of the Sentinel Range, Antarctica, was not known until reconnaissance flights and scientific traverses in the International Geophysical Year (IGY), 1957–1958. These explorations revealed the range to be twenty miles in length, with a large number of high peaks culminating in Mt. Vinson, the highest on the Antarctic continent at nearly 4900 meters. The discoveries captured the interest of the U.S. and world mountaineering communities setting off a competition to achieve the first climb of Vinson. The challenge was tempered only by the range's remoteness from the coast of Antarctica and the formidable logistics of mounting a mountaineering expedition. The US which had the most advanced ski-equipped cargo aircraft, had an established post-IGY policy that prohibited adventure expeditions that could divert logistic resources from the scientific programme. This paper discusses Mt. Vinson competition within the US and international climbing communities, mounting national pressures to achieve the first climb, and a reversal in policy by the US Antarctic Policy Group that resulted in the 1966–1967 American Antarctic Mountaineering Expedition's first ascents of Vinson and five other high peaks. Today, between 100 and 200 persons climb Mt. Vinson each austral summer.

Whole Heliosphere Interval

AbstractThe Whole Heliosphere Interval is an international observing and modeling effort to characterize the three-dimensional interconnected solar-heliospheric-planetary system, i.e., the “heliophysical” system. WHI was part of the International Heliophysical Year, on the 50th anniversary of the International Geophysical Year, and benefited from hundreds of observatories and instruments participating in IHY activities. WHI describes the 3-D heliosphere originating from solar Carrington Rotation 2068, March 20–April 16, 2008. The focus of IAU JD16 was on analyses of observations obtained during WHI, and simulations and modeling involving those data and that period. Consideration of the WHI interval in the context of surrounding solar rotations and/or compared to last solar minimum was also encouraged. Our goal was to identify connections and commonalities between the various regions of the heliosphere.
