INTERNATIONAL TRANS ANTARCTIC SCIENTIFIC EXPEDITION
From its original formulation in 1990, the International Trans Antarctic Scientific Expedition ( ITASE ) has had as its primary aim the collection and interpretation of a continental-wide array of environmental parameters assembled through the coordinated efforts of scientists from several nations. The primary planned product of this cooperative endeavor is the description and understanding of environmental change in Antarctica over the last ~200 years. As a demonstration of the importance of the original scientific objectives posed by ITASE, they were adopted as a key science initiative by both the International Geosphere-Biosphere Program (IGBP) and the Scientific Committee on Antarctic Research (SCAR).
