The depths of the ocean : a general account of the modern science of oceanography based largely on the scientific researches of the Norwegian steamer Michael Sars in the North Atlantic depthsofoceangen00murr Year: 1912 198 DEPTHS OF THE OCEAN basin (see Fig. 143), more than 3000 metres deep in the central portion. From this depth the floor rises gradually towards the continental slope on either side. The main features of the continental slope and shelf along the coast of Norway will be grasped by reference to the accompanying diagram (Fig. 144). The term 'coast banks' is usually applied to the higher parts of the submerged continental plateau or continental shelf, which are frequented by fishermen ; there is often a marked 'edge' between the plateau and the continental slope. The continental shelf fringes to a greater or less extent the whole of the coasts of the Norwegian Sea, and occupies alto- gether about a third of its entire superficial area. This shelf is covered by depths down to 200 metres with channels down to 600 metres. In water shallower than 200 metres there are only comparatively small banks, the great- est being at Lofoten and Romsdal and round the Faroes and Iceland. Deeper than 600 metres the con- tinental slope is steep; the bathymetrical curves for 600 and 1000 metres lie every- where in close prox- imity to one another, and the area of the sea-bottom between them is no more than per cent of the whole extent of the Norwegian Sea.

The distribution of the deposit-types over the floor of the North Atlantic is shown on Map IV., an examination of which bears out the statement that the terrigenous deposits are relatively more important in the North Atlantic than in the other oceans, in correl
