Diagrams of ice with layers
“Thursday, February 22d. The net-line has pointed west all day till now, afternoon, when it is pointing straight up and down, and we are presumably lying still. The wind slackened to-day till it was quite calm in the afternoon. Then there came a faint breeze from the southwest and from the west, and this evening the long-dreaded northwester has come at last. At 9 P.M. it is blowing pretty hard from N.N.W. An observation of Capella taken in the afternoon would seem to show that we are in any case not farther north than 80° 11′ and this after almost four days’ south wind. Whatever can be the meaning of this? Is there dead-water under the ice, keeping it from going either forward or backward? The ice to starboard cracked yesterday, away beyond the bear-trap. The thickness of the solid floe was 11½ feet (3.45 metres), but, besides this, other ice was packed on to it below. Where it was broken across, the floe showed a marked stratified formation, recalling the stratification of a glacier. Even the darker and dirtier strata were there, the color in this case produced by the brownish-red organisms that inhabit the water, specimens of which I found at an earlier date. In several places the strata were bent and broken, exactly in the same manner as the geological strata forming the earth’s crust. This was evidently the result of the horizontal pressure in the ice at the time of packing. It was especially noticeable at one place, near a huge mound formed during the last pressure. Here the strata looked very much as they are represented in the annexed drawing.[15]
It was extraordinary too to see how this floe of over three yards in thickness was bent into great waves without breaking. This was clearly done by pressure, and was specially noticeable, more particularly near the pressure-ridges, which had forced the floe down so that its upper surface lay even with the water-line, while at other places it was a good half-yard above it, in these last cases thrust up by ice pressed in below. It all shows how extremely plastic these floes are, in spite of the cold; the temperature of the ice near the surface must have been from 4° Fahr. to 22° Fahr. below zero (-20° to -30° C.) at the time of these pressures. In many places the bending had been too violent, and the floe had cracked. The cracks were often covered with loose ice, so that one could easily enough fall into them, just as in crossing a dangerous glacier.
“Saturday, February 24th. Observations to-day show us to be in 79° 54′ north latitude, 132° 57′ east longitude. Strange that we should have come so far south when the north or northwest wind only blew for twenty-four hours.
“Sunday, February 25th. It looks as if the ice were drifting eastward now. Oh! I see pictures of summer and green trees and rippling streams. I am reading of valley and mountain life, and I grow sick at heart and enervated. Why dwell on such things just now? It will be many a long day before we can see all that again. We are going at the miserable pace of a snail, but not so surely as it goes. We carry our house with us; but what we do one day is undone the next.
“Monday, February 26th. We are drifting northeast. A tremendous snow-storm is going on. The wind has at times a velocity of over 35 feet per second; it is howling in the rigging, whistling over the ice, and the snow is drifting so badly that a man might be lost in it quite near at hand. We are sitting here listening to the howling in the chimney and in the ventilators, just as if we were sitting in a house at home in Norway. The wings of the windmill have been going round at such a rate that you could hardly distinguish them; but we have had to stop the mill this evening because the accumulators are full, and we fastened up the wings so that the wind might not destroy them. We have had electric light for almost a week now.
“This is the strongest wind we have had the whole winter. If anything can shake up the ice and drive us north, this must do it. But the barometer is falling too fast; there will be north wind again presently. Hope has been disappointed too often; it is no longer elastic; and the gale makes no great impression on me. I look forward to spring and summer, in suspense as to what change they will bring. But the Arctic night, the dreaded Arctic night, is over, and we have daylight once again. I must say that I see no appearance of the sunken, wasted faces which this night ought to have produced; in the clearest daylight and the brightest sunshine I can only discover plump, comfortable-looking ones. It is curious enough, though, about the light. We used to think it was like real day down here when the incandescent lamps were burning; but now, coming down from the daylight, though they may be all lit, it is like coming into a cellar. When the arc lamp has been burning all day, as it has to-day, and is then put out and its place supplied by the incandescent ones, the effect is much the same.
“Tuesday, February 27th. Drifting E.S.E. My pessimism is justified. A strong west wind has blown almost all day; the barometer is low, but has begun to rise unsteadily. The temperature is the highest we have had all winter; to-day’s maximum is 15° Fahr. above zero (-9.7° C.). At 8 P.M. the thermometer stood at 7° Fahr. below zero (-22° C.). The temperature rises and falls almost exactly conversely with the barometer. This afternoon’s observation places us in about 80° 10′ north latitude.
“Wednesday, February 28th. Beautiful weather to-day, almost still, and temperature only about 15° Fahr. to 22° Fahr. below zero (-26° to -30° 5′ C.). There were clouds in the south, so that not much was to be seen of the sun; but it is light wonderfully long already. Sverdrup and I went snow-shoeing after dinner—the first time this year that we have been able to do anything of the kind in the afternoon. We made attempts to pump yesterday and to-day; there ought to be a little water, but the pump would not suck, though we tried both warm water and salt. Possibly there is water frozen round it, and possibly there is no water at all. In the engine-room there has been no appearance of water for more than a month, and none comes into the forehold, especially now that the bow is raised up by the pack-ice; so if there is any it can only be a little in the hold. This tightening may be attributed chiefly to the frost.
“The wind has begun to blow again from the S.S.W. this evening, and the barometer is falling, which ought to mean good wind coming; but the barometer of hope does not rise above its normal height. I had a bath this evening in a tin tub in the galley; trimmed and clean, one feels more of a human being.
