In northern Europe, a deej) marginal channel is found in the Skagerrak close to the Norwegian coast: the deepest part lies to the east at the entrance of the Kattegat, and here reaches more than 350 fm. Farther north, off Norway, marginal depressions deeper than the outer shelf are also frequent, especially off More and Romsdal provinces (Fig. 4). Off Labrador, a longitudinal channel runs parallel to the coast for more than 250 nautical miles, with de])ths of 300-400 fm, inside a shallower outer shelf; another smaller channel is found to the north of Belle Isle.
