With the knowledge we now possess of the state of the ice in the Murman Sea--so the sea between Kola and Novaya Zemlya is called on the old maps--it is possible to sail during the latter part of summer from the White Sea to Matotschkin without needing to fear the least hindrance from ice. For several decades back, however, in consequence of want of knowledge of the proper season and the proper course, the case has been quite different--as is sufficiently evident from the account of the difficulties and dangers which the renowned Russian navigator, Count Lütke, met with during his repeated voyages four summers in succession (1821-1824) along the west coast of Novaya Zemlya. A skilful walrus-hunter can now, with a common walrus-hunting vessel, in a single summer, sail further in this sea than formerly could an expedition, fitted out with all the resources of a naval yard, in four times as long time.
There are four ways of passing from the Murman Sea to the Kara Sea, viz:--
_a._ Yugor Sound--the Fretum Nassovicum of the old Dutchmen--between Vaygats Island and the mainland.
_b._ The Kara Port, between Vaygats Island and Novaya Zemlya.
_c._ Matotschkin Sound, which between 73° and 74° N. Lat. divides Novaya Zemlya into two parts, and, finally,
_d._ The course north of the double island. The course past the northernmost point of Novaya Zemlya is not commonly clear of ice till the beginning of the month of September, and perhaps ought, therefore, not to be chosen for an expedition having for its object to penetrate far to the eastward in this sea. Yugor Sound and the Kara Port are early free of fast ice, but instead, are long rendered difficult to navigate by considerable masses of drift ice, which are carried backwards and forwards in the bays on both sides of the sound by the currents which here alternate with the ebb and flow of the tide. Besides, at least in Yugor Sound, there are no good harbours, in consequence of which the drifting masses of ice may greatly inconvenience the vessels, which by these routes attempt to enter the Kara Sea. Matotschkin Sound, again, forms a channel nearly 100 kilometres long, deep and clear, with the exception of a couple of shoals, the position of which is known, which indeed is not usually free from fast ice until the latter half of July, but, on the other hand, in consequence of the configuration of the coast, is less subject to be obstructed by drift ice than the southern straits. There are good harbours at the eastern mouth of the sound. In 1875 and 1876 both the sound and the sea lying off it were completely open in the end of August, but the ice was much earlier broken up also on the eastern side, so that a vessel could without danger make its way among the scattered pieces of drift ice. The part of Novaya Zemlya which is first visited by the walrus-hunters in spring is usually just the west coast off Matotschkin.
