The fourth IPY, which began in March 2007 and actually covered two full years, ended last month, after 160 scientific projects were undertaken by researchers from over 60 countries.
A joint project by the International Council for Science (ICSW) and World Meteorological Organization. (WMO), the IPY hoped to spearhead efforts to better monitor and understand the Arctic and Antarctic regions." See full article
