Because of its position between the North Atlantic and the Arctic oceans, its young age, small size, and diversity of geological structures, the Norwegian-Greenland Sea provided a unique target for deep drilling on Leg 38 of the Glomar Challenger. From studies of the sediments and basement rocks it was expected to gain insight particularly as to the following: 1) The tectonic framework and evolution of this area with special emphasis on the continental margins and on questions concerned with shifts of spreading axis and existence of foundered continental areas. 2) The youngest times of existence of land bridges between Eurasia and North America and the effect these land bridges had on water circulation and paleoclimates. 3) The date of the initiation of glaciation and dates of glacial advances and retreats. 4) Description of the Tertiary marine microfauna and microflora of the Norwegian-Greenland Sea, which are essentially unknown at present, and investigation of their similarity with microfauna and microflora from other areas.
