Extract

In offering a few remarks on a subject which belongs, in the first instance, to the province of physical geography, it will be necessary forme to point out certain hydrographical details, whilst, endeavouring to deduce from these details conclusions having a geological bearing. Oceanography is almost a science in itself, especially if we regard it from a geological point of view, as something more than a mere description of water-spaces and soundings. Ever since the days when the deep oceans were first explored for the purpose of laying the telegraph cables some of the leading facts were made known, and have since become familiar to all students of physical geography.

page 99 note 4 This remark refers to the large chart which was exhibited at the Bristol meeting. Since then Messrs. Bartholomew have prepared a more elaborate map based upon the outlines of that chart. This will serve to give a general idea of the subject of the paper, viz. “The Eastern Margin of the North Atlantic Basin”. It will be readily understood that details can only be shown on a larger scale. Indeed, for very close work in connection with the “suboceanie Continental slope”, it may be doubted whether a sufficient number of reliable soundings have been taken as yet to warrant any detailed mapping of these slopes in some cases. Notwithstanding the imperfection of the record, however, there are some features in the marginal line, such as the ‘Fosse de cap Breton’, which have been clearly established (see Fig. 4). It will be observed that a very small area in Messrs. Bartholomew's chart, to the W.S.W. of Madeira, shows depths exceeding 3,000 fathoms. This, however, has no bearing on the subject of my paper.

Soc. vol. liv, p. 644) a depth of 230 fathoms thirty miles west of Cape Mary Harmsworth, it is possible that a bight of the deep North Polar ocean may extend for some distance between the Franz Josef Archipelago and Spitzbergen.Google Scholar
