Excerpt: ... evidently the same formation as the Norwegian and the British continental shelves, and lies at very similar depths, both of which facts might seem difficult to explain if the land has been recently submerged as much as 60 or 80 m. It might however, be possible, that during the glacial periods the sea-level stood rather lower on the Faeroes than in Norway. It is for instance probable, that the volume of the ocean was reduced by the formation of the great ice-sheets; how much the sea-level sank in this manner cannot be computed; but it may have been appreciable if we assume that the European, American, Siberian, and perhaps also the Antarctic ice ages were simultaneous. The fall of sea-level was in Norway apparently much checked by the isostatic movements of the land due to the pressure of the great ice-caps. On the Faeroes these isostatic movements may not have been very great, as the ice-cap cannot have been very thick; thus the total result may have been that the fall of sea-level caused a considerable lowering of the shoreline on its coasts. There is still another possibility: if we assume that the Scandinavian British platform has actually been depressed by the weight of the inland ice during its greatest extension, we must also assume that at the same time there has been an isostatic movement of the bottom of the Norwegian sea in the opposite direction, and thus may the ridge on which the Faeroes are situated have been actually raised. The absence of a typical broad coast platform on the tvheather-beaten Orkneys and the Shetland Islands is also interesting. It was above (p. 96) pointed out that a narrow coast platform with numerous skerries and shoals probably extends along the western coast of Scotland and the Hebrides, this regions...
