Part 4

Saw two sea leopards this evening, one in the water making short, lazy dives under the floes. It had a beautiful sinuous movement.

I have asked Pennell to prepare a map of the pack; it ought to give some idea of the origin of the various forms of floes, and their general drift. I am much inclined to think that most of the pressure ridges are formed by the pa.s.sage of bergs through the comparatively young ice. I imagine that when the sea freezes very solid it carries bergs with it, but obviously the enormous ma.s.s of a berg would need a great deal of stopping. In support of this view I notice that most of the pressure ridges are formed by pieces of a sheet which did not exceed one or two feet in thickness--also it seems that the screwed ice which we have pa.s.sed has occurred mostly in the regions of bergs. On one side of the tabular berg pa.s.sed yesterday pressure was heaped to a height of 15 feet--it was like a ship's bow wave on a large scale. Yesterday there were many bergs and much pressure; last night no bergs and practically no pressure; this morning few bergs and comparatively little pressure. It goes to show that the unconfined pack of these seas would not be likely to give a ship a severe squeeze.

Saw a young Emperor this morning, and whilst trying to capture it one of Wilson's new whales with the sabre dorsal fin rose close to the ship. I estimated this fin to be 4 feet high.

It is pretty to see the snow petrel and Antarctic petrel diving on to the upturned and flooded floes. The wash of water sweeps the Euphausia [3] across such submerged ice. The Antarctic petrel has a pretty crouching att.i.tude.

_Tuesday, December_ 20.--Noon 68 41' S., 179 28' W. Made good S. 36 W. 58; C. Crozier S. 20 W. 563'.--The good conditions held up to midnight last night; we went from lead to lead with only occasional small difficulties. At 9 o'clock we pa.s.sed along the western edge of a big stream of very heavy bay ice--such ice as would come out late in the season from the inner reaches and bays of Victoria Sound, where the snows drift deeply. For a moment one imagined a return to our bad conditions, but we pa.s.sed this heavy stuff in an hour and came again to the former condition, making our way in leads between floes of great area.

Bowers reported a floe of 12 square miles in the middle watch. We made very fair progress during the night, and an excellent run in the morning watch. Before eight a moderate breeze sprang up from the west and the ice began to close. We have worked our way a mile or two on since, but with much difficulty, so that we have now decided to bank fires and wait for the ice to open again; meanwhile we shall sound and get a haul with tow nets. I'm afraid we are still a long way from the open water; the floes are large, and where we have stopped they seem to be such as must have been formed early last winter. The signs of pressure have increased again. Bergs were very scarce last night, but there are several around us to-day. One has a number of big humps on top. It is curious to think how these big blocks became perched so high. I imagine the berg must have been calved from a region of hard pressure ridges. [Later] This is a mistake--on closer inspection it is quite clear that the berg has tilted and that a great part of the upper strata, probably 20 feet deep, has slipped off, leaving the humps as islands on top.

It looks as though we must exercise patience again; progress is more difficult than in the worst of our experiences yesterday, but the outlook is very much brighter. This morning there were many dark shades of open water sky to the south; the westerly wind ruffling the water makes these cloud shadows very dark.

The barometer has been very steady for several days and we ought to have fine weather: this morning a lot of low cloud came from the S.W., at one time low enough to become fog--the clouds are rising and dissipating, and we have almost a clear blue sky with sunshine.

_Evening_.--The wind has gone from west to W.S.W. and still blows nearly force 6. We are lying very comfortably alongside a floe with open water to windward for 200 or 300 yards. The sky has been clear most of the day, fragments of low stratus occasionally hurry across the sky and a light cirrus is moving with some speed. Evidently it is blowing hard in the upper current. The ice has closed--I trust it will open well when the wind lets up. There is a lot of open water behind us. The berg described this morning has been circling round us, pa.s.sing within 800 yards; the bearing and distance have altered so un-uniformly that it is evident that the differential movement between the surface water and the berg-driving layers (from 100 to 200 metres down) is very irregular. We had several hours on the floe practising ski running, and thus got some welcome exercise. Coal is now the great anxiety--we are making terrible inroads on our supply--we have come 240 miles since we first entered the pack streams.

The sounding to-day gave 1804 fathoms--the water bottle didn't work, but temperatures were got at 1300 and bottom.

The temperature was down to 20 last night and kept 2 or 3 degrees below freezing all day.

The surface for ski-ing to-day was very good.

_Wednesday, December_ 21.--The wind was still strong this morning, but had shifted to the south-west. With an overcast sky it was very cold and raw. The sun is now peeping through, the wind lessening and the weather conditions generally improving. During the night we had been drifting towards two large bergs, and about breakfast time we were becoming uncomfortably close to one of them--the big floes were binding down on one another, but there seemed to be open water to the S.E., if we could work out in that direction.

(_Note_.--All directions of wind are given 'true' in this book.)

_Noon Position_.--68 25' S., 179 11' W. Made good S. 26 E. 2.5'. Set of current N., 32 E. 9.4'. Made good 24 hours--N. 40 E. 8'. We got the steam up and about 9 A.M. commenced to push through. Once or twice we have spent nearly twenty minutes pushing through bad places, but it looks as though we are getting to easier water. It's distressing to have the pack so tight, and the bergs make it impossible to lie comfortably still for any length of time.

Ponting has made some beautiful photographs and Wilson some charming pictures of the pack and bergs; certainly our voyage will be well ill.u.s.trated. We find quite a lot of sketching talent. Day, Taylor, Debenham, and Wright all contribute to the elaborate record of the bergs and ice features met with.

5 P.M.--The wind has settled to a moderate gale from S.W. We went 2 1/2 miles this morning, then became jammed again. The effort has taken us well clear of the threatening bergs. Some others to leeward now are a long way off, but they _are_ there and to leeward, robbing our position of its full measure of security. Oh! but it's mighty trying to be delayed and delayed like this, and coal going all the time--also we are drifting N. and E.--the pack has carried us 9'

N. and 6' E. It really is very distressing. I don't like letting fires go out with these bergs about.

Wilson went over the floe to capture some penguins and lay flat on the surface. We saw the birds run up to him, then turn within a few feet and rush away again. He says that they came towards him when he was singing, and ran away again when he stopped. They were all one year birds, and seemed exceptionally shy; they appear to be attracted to the ship by a fearful curiosity._7_

A chain of bergs must form a great obstruction to a field of pack ice, largely preventing its drift and forming lanes of open water. Taken in conjunction with the effect of bergs in forming pressure ridges, it follows that bergs have a great influence on the movement as well as the nature of pack.

_Thursday, December_ 22.--Noon 68 26' 2'' S., 197 8' 5'' W. Sit. N. 5 E. 8.5'.--No change. The wind still steady from the S.W., with a clear sky and even barometer. It looks as though it might last any time. This is sheer bad luck. We have let the fires die out; there are bergs to leeward and we must take our chance of clearing them--we cannot go on wasting coal.

There is not a vestige of swell, and with the wind in this direction there certainly ought to be if the open water was reasonably close. No, it looks as though we'd struck a streak of real bad luck; that fortune has determined to put every difficulty in our path. We have less than 300 tons of coal left in a ship that simply eats coal. It's alarming--and then there are the ponies going steadily down hill in condition. The only encouragement is the persistence of open water to the east and south-east to south; big lanes of open water can be seen in that position, but we cannot get to them in this pressed up pack.

Atkinson has discovered a new tapeworm in the intestines of the Adelie penguin--a very tiny worm one-eighth of an inch in length with a propeller-shaped head.

A crumb of comfort comes on finding that we have not drifted to the eastward appreciably.

_Friday, December_ 23.--The wind fell light at about ten last night and the ship swung round. Sail was set on the fore, and she pushed a few hundred yards to the north, but soon became jammed again. This brought us dead to windward of and close to a large berg with the wind steadily increasing. Not a very pleasant position, but also not one that caused much alarm. We set all sail, and with this help the ship slowly carried the pack round, pivoting on the berg until, as the pressure relieved, she slid out into the open water close to the berg. Here it was possible to 'wear ship,' and we saw a fair prospect of getting away to the east and afterwards south. Following the leads up we made excellent progress during the morning watch, and early in the forenoon turned south, and then south-west.

We had made 8 1/2' S. 22 E. and about 5' S.S.W. by 1 P.M., and could see a long lead of water to the south, cut off only by a broad strip of floe with many water holes in it: a composite floe. There was just a chance of getting through, but we have stuck half-way, advance and retreat equally impossible under sail alone. Steam has been ordered but will not be ready till near midnight. Shall we be out of the pack by Christmas Eve?

The floes to-day have been larger but thin and very sodden. There are extensive water pools showing in patches on the surface, and one notes some that run in line as though extending from cracks; also here and there close water-free cracks can be seen. Such floes might well be termed '_composite_' floes, since they evidently consist of old floes which have been frozen together--the junction being concealed by more recent snow falls.

A month ago it would probably have been difficult to detect inequalities or differences in the nature of the parts of the floes, but now the younger ice has become waterlogged and is melting rapidly, hence the pools.

I am inclined to think that nearly all the large floes as well as many of the smaller ones are 'composite,' and this would seem to show that the cementing of two floes does not necessarily mean a line of weakness, provided the difference in the thickness of the cemented floes is not too great; of course, young ice or even a single season's sea ice cannot become firmly attached to the thick old bay floes, and hence one finds these isolated even at this season of the year.

Very little can happen in the personal affairs of our company in this comparatively dull time, but it is good to see the steady progress that proceeds unconsciously in cementing the happy relationship that exists between the members of the party. Never could there have been a greater freedom from quarrels and trouble of all sorts. I have not heard a harsh word or seen a black look. A spirit of tolerance and good humour pervades the whole community, and it is glorious to realise that men can live under conditions of hardship, monotony, and danger in such bountiful good comradeship.

Preparations are now being made for Christmas festivities. It is curious to think that we have already pa.s.sed the longest day in the southern year.

Saw a whale this morning--estimated 25 to 30 feet. Wilson thinks a new species. Find Adelie penguins in batches of twenty or so. Do not remember having seen so many together in the pack.

_After midnight, December_ 23.--Steam was reported ready at 11 P.M. After some pushing to and fro we wriggled out of our ice prison and followed a lead to opener waters.

We have come into a region where the open water exceeds the ice; the former lies in great irregular pools 3 or 4 miles or more across and connecting with many leads. The latter, and the fact is puzzling, still contain floes of enormous dimensions; we have just pa.s.sed one which is at least 2 miles in diameter. In such a scattered sea we cannot go direct, but often have to make longish detours; but on the whole in calm water and with a favouring wind we make good progress. With the sea even as open as we find it here it is astonishing to find the floes so large, and clearly there cannot be a southerly swell. The floes have water pools as described this afternoon, and none average more than 2 feet in thickness. We have two or three bergs in sight.

_Sat.u.r.day, December 24, Christmas Eve_.--69 1' S., 178 29' W. S. 22 E. 29'; C. Crozier 551'. Alas! alas! at 7 A.M. this morning we were brought up with a solid sheet of pack extending in all directions, save that from which we had come. I must honestly own that I turned in at three thinking we had come to the end of our troubles; I had a suspicion of anxiety when I thought of the size of the floes, but I didn't for a moment suspect we should get into thick pack again behind those great sheets of open water.

All went well till four, when the white wall again appeared ahead--at five all leads ended and we entered the pack; at seven we were close up to an immense composite floe, about as big as any we've seen. She wouldn't skirt the edge of this and she wouldn't go through it. There was nothing to do but to stop and bank fires. How do we stand?--Any day or hour the floes may open up, leaving a road to further open water to the south, but there is no guarantee that one would not be hung up again and again in this manner as long as these great floes exist. In a fortnight's time the floes will have crumbled somewhat, and in many places the ship will be able to penetrate them.

What to do under these circ.u.mstances calls for the most difficult decision.

If one lets fires out it means a dead loss of over 2 tons, when the boiler has to be heated again. But this 2 tons would only cover a day under banked fires, so that for anything longer than twenty-four hours it is economy to put the fires out. At each stoppage one is called upon to decide whether it is to be for more or less than twenty-four hours.

Last night we got some five or six hours of good going ahead--but it has to be remembered that this costs 2 tons of coal in addition to that expended in doing the distance.

If one waits one probably drifts north--in all other respects conditions ought to be improving, except that the southern edge of the pack will be steadly augmenting.

Rough Summary of Current in Pack

Dec. Current Wind

11-12 S. 48 E. 12'? N. by W. 3 to 5 13-14 N. 20 W. 2' N.W. by W. 0-2 14-15 N. 2 E. 5.2' S.W. 1-2 15-17 apparently little current variable light 20-21 N. 32 E. 9.4 N.W. to W.S.W. 4 to 6 21-22 N. 5 E. 8.5 West 4 to 5

The above seems to show that the drift is generally with the wind. We have had a predominance of westerly winds in a region where a predominance of easterly might be expected.

Now that we have an easterly, what will be the result?
