There have been three previous IPYs - held in 1882-83, 1932-33 and 1957-58 - each of which led to scientists gaining a much better knowledge of the remote regions.There have been three previous IPYs - held in 1882-83, 1932-33 and 1957-58 - each of which led to scientists gaining a much better knowledge of the remote regions.
David Carlson, direction of the IPY co-ordination team, said the scale of the global undertaking presented a number of logistical problems.David Carlson, direction of the IPY co-ordination team, said the scale of the global undertaking presented a number of logistical problems.

    		Projects to be undertaken over the next two years have six major aims:
    • determine the current environmental status of the polar regions
    • quantify past and present environmental and social changes, and improve future projections
    • understand links between the poles and the rest of the planet
    • investigate the frontiers of science in the regions
    • use the polar areas to develop and enhance observation of the Earth's interior and of space
    • explore the cultural, historical and social aspects of circumpolar human communities
