International Upper Mantle Project

International Upper Mantle Project

UMP (abbreviated as UMP) is an international collaborative research project carried out between 1962 and 1970 with the aim of elucidating the properties of the Earth's upper mantle and its influence on the development of the Earth's crust. The Upper Mantle Committee was established within the International Union of Geodesy and Geophysics, and about 50 countries participated in various observations. During this period, the ocean floor spreading hypothesis (1961) and the Vine-Matthews hypothesis (1963), which played a crucial role in establishing this spreading hypothesis, were proposed, and were synthesized as plate tectonics in 1967-1968. The results of UMP were carried over to the International Earth's Interior Dynamics Programme (abbreviated as GDP) in the 1970s.

略称UMP(アンプ)。地球の上部マントルの性質や、それが地殻の発展に及ぼす影響などを解明することを目的として、1962~1970年の期間に実施された国際協同研究事業。国際測地学地球物理学連合内に上部マントル委員会が設けられ、約50か国が参加して各種の観測を行った。この期間中には、海洋底拡大説(1961)、さらに、この拡大説の確立に決定的な役割を果たしたバイン‐マシューズ仮説(1963)が提唱され、1967~1968年にプレートテクトニクスとして総合された。UMPの成果は、1970年代の国際地球内部ダイナミクス計画(略称GDP)に引き継がれていった。
