From the middle of March it looked as if the equinoctial gales were over, for we had quite fine weather all the way to Buenos Aires. Cape Horn was passed on March 31 in the most delightful weather -- a light westerly breeze, not a cloud in the sky, and only a very slight swell from the west. Who would have guessed that such splendid weather was to be found in these parts? -- and that in March, the most stormy month of the year.
Lieutenant Gjertsen and Kutschin collected plankton all the time; the latter smiled all over his face whenever he chanced to get one or two "tadpoles" in his tow-net.
From the Falkland Islands onward the Fram was washed and painted, so that we might not present too "Polar" an appearance on arrival at Buenos Aires.
It may be mentioned as a curious fact that the snow with which we filled our water-tanks on the Barrier did not melt till we were in the River La Plata, which shows what an even temperature is maintained in the Fram's hold.
About midday on Easter Sunday we were at the mouth of the River La Plata, without seeing land, however. During the night the weather became perfect, a breeze from the south, moonlight and starry, and we went up the river by soundings and observations of the stars until at 1 a.m. on Monday, when we had the Recalada light-ship right ahead. We had not seen any light since we left Madeira on September 9. At 2.30 the same morning we got a pilot aboard, and at seven in the evening we anchored in the roads of Buenos Aires.
We had then been nearly once round the world, and for over seven months the anchor had not been out.
We had reckoned on a two months' voyage from the ice, and it had taken us sixty-two days.
The Oceanographical Cruise.
According to the programme, the Fram was to go on an oceanographical cruise in the South Atlantic, and my orders were that this was to be arranged to suit the existing circumstances. I had reckoned on a cruise of about three months. We should have to leave Buenos Aires at the beginning of October to be down in the ice at the right time (about the New Year).
As we were too short-handed to work the ship, take soundings, etc., the following four seamen were engaged: H. Halvorsen, A. Olsen, F. Steller, and J.
Andersen.
At last we were more or less ready, and the Fram sailed from Buenos Aires on June 8, 1911, the anniversary of our leaving Horten on our first hydrographic cruise in the North Atlantic. I suppose there was no one on board on June 8, 1910, who dreamed that a year later we should go on a similar cruise in the South.
We had a pilot on board as far as Montevideo, where we arrived on the afternoon of the 9th; but on account of an increasing wind (pampero) we had to lie at anchor here for a day and a half, as the pilot could not be taken off. On Saturday afternoon, the 10th, he was fetched off by a big tug-boat, on board of which was the Secretary of the Norwegian Consulate. This gentleman asked us if we could not come into the harbour, as "people would like to see the ship." I promised to come in on the way back, "if we had time."
On Sunday morning, the 11th, we weighed anchor, and went out in the most lovely weather that can be imagined. Gradually the land disappeared, and in the course of the evening we lost the lights; we were once more out in the Atlantic, and immediately everything resumed its old course.
In order to save our supply of preserved provisions as much as possible, we took with us a quantity of live poultry, and no fewer than twenty live sheep, which were quartered in the "farmyard" on the port side of the vessel's fore-deck. Sheep and hens were all together, and there was always a most beautiful scent of hay, so that we had not only sea air, but "country air." In spite of all this delightful air, three or four of the crew were down with influenza, and had to keep their berths for some days.
I reckoned on being back at Buenos Aires by the beginning of September, and on getting, if possible, one station a day. The distance, according to a rough
calculation, was about 8,000 nautical miles, and I laid down the following plan: To go about east by north with the prevailing northerly and north-westerly winds to the coast of Africa, and there get hold of the south-east trade. If we could not reach Africa before that date, then to turn on July 22 and lay our course with the south-east trade for St. Helena, which we could reach before August 1; from there again with the same wind to South Trinidad (August 11 or 12); on again with easterly and north-easterly winds on a south-westerly course until about August 22, when the observations were to be concluded, and we should try to make Buenos Aires in the shortest time.
That was the plan that we attempted. On account of the fresh water from the River La Plata, we did not begin at once to take samples of water, and with a head-wind, north-east, we lay close-hauled for some days. We also had a pretty stiff breeze, which was another reason for delaying the soundings until the 17th.
For taking samples of water a winch is used, with a sounding-line of, let us say, 5,000 metres (2,734 fathoms), on which are hung one or more tubes for catching water; we used three at once to save time. Now, supposing water and temperatures are to be taken at depths of 300, 400, and 500 metres (164, 218, and 273 fathoms), Apparatus III. (see diagram) is first hung on, about 20 metres (10 fathoms) from the end of the line, where a small weight (a) hangs; then it is lowered until the indicator-wheel, over which the line passes, shows 100 metres (54 fathoms); Apparatus II. is then put on, and it is lowered again for another 100 metres, when Apparatus I. is put on and the line paid out for 300 metres (164 fathoms) -- that is, until the indicator-wheel shows 500 metres (273
fathoms). The upper Apparatus (I.) is then at 300 metres (164 fathoms), No. II.
at 400 metres (218 fathoms), and No. III. at 500 metres (273 fathoms). Under Apparatus I. and II. is hung a slipping sinker (about 8 centimetres, or 3 1/4
inches, long, and 3 centimetres, or 1 1/4 inches, in diameter). To the water-samplers are attached thermometers (b) in tubes arranged for the purpose.
The water-samplers themselves consist of a brass cylinder (c), about 38
centimetres (15 inches) long and 4 centimetres (1 1/2 inches) in diameter (about half a litre of water), set in a frame (d). At about the middle of the cylinder are pivots, which rest in bearings on the frame, so that the cylinder can be swung 180 degrees (straight up and down).
The cylinder, while being lowered in an inverted position, is open at both ends, so that the water can pass through. But at its upper and lower ends are valves,
working on hinges and provided with packing. When the apparatus is released, the cylinder swings round, and these valves then automatically close the ends of the cylinder. The water that is thus caught in the cylinder at the required depth remains in it while it is being heaved up, and is collected in bottles. When the apparatus is released, the column of mercury in the thermometer is broken, and the temperature of the water is read at the same depth as the water is taken from.
The release takes place in the following manner: when all the cylinders have been lowered to the required depths, they are left hanging for a few minutes, so that the thermometers may be set at the right temperature before the column of mercury is broken. Then a slipping sinker is sent down the line. When this sinker strikes the first apparatus, a spring is pressed, a hook (e) which has held the cylinder slips loose, and the cylinder turns completely over (Apparatus I.). As it does this, the valves, as already mentioned, close the ends of the cylinder, which is fixed in its new position by a hook in the bottom of the frame. At the same instant the slipping sinker that hangs under Apparatus I. is released, and continues the journey to Apparatus II., where the same thing happens. It is then repeated with Apparatus III. When they are all ready, they are heaved in.
By holding one's finger on the line one can feel, at all events in fairly calm weather, when the sinkers strike against the cylinders; but I used to look at my watch, as it takes about half a minute for the sinker to go down 100 metres.
The necessary data are entered in a book.
On the morning of the 17th, then, the sails were clewed up, and the Fram began to roll even worse than with the sails set. We first tried taking soundings with a sinker of 66 pounds, and a tube for taking specimens of the sea-bed. At 2,000
metres (1,093 fathoms) or more the line (piano wire) broke, so that sinker, tube, and over 2,000 metres of line continued their way unhindered to the bottom. I had thought of taking samples of water at 4,000, 3,000, and 2,000 metres (2,187, 1,639, 1,093 fathoms), and so on, and water-cylinders were put on from 0 to 2,000 metres. This, however, took six hours. Next day, on account of the heavy sea, only a few samples from 0 to 100 metres (54 fathoms) were taken. On the third day we made another attempt to get the bottom. This time we got specimens of the sea-bed from about 4,500 metres (about 2,500 fathoms); but the heaving in and taking of water samples and temperatures occupied eight hours, from 7 a.m. till 3 p.m., or a third part of the twenty-four hours. In this way we should want at least nine months on the route that had been laid down; but as,
unfortunately, this time was not at our disposal, we at once gave up taking specimens of the bottom and samples of water at greater depths than 1,000
metres (546 fathoms). For the remainder of the trip we took temperatures and samples of water at the following depths: 0, 5, 10, 25, 50, 75, 100, 150, 200, 250, 300, 400, 500, 750, and 1,000 metres (0, 2 3/4, 5 1/2, 13 1/2, 27, 41, 54, 81, 108, 135, 164, 218, 273, 410, and 546 fathoms), in all, fifteen samples from each station, and from this time forward we went on regularly with one station every day. Finally, we managed to heave up two water-cylinders on the same line by hand without great difficulty. At first this was done with the motor and sounding-machine, but this took too long, and we afterwards used nothing but a light hand-winch. Before very long we were so practised that the whole business only took two hours.
These two hours were those we liked best of the twenty-four. All kinds of funny stories were told, especially about experiences in Buenos Aires, and every day there was something new. Here is a little yarn:
One of the members of the expedition had been knocked down by a motor-car in one of the busiest streets; the car stopped and of course a crowd collected at once. Our friend lay there, wondering whether he ought not to be dead, or at least to have broken a leg, so as to get compensation. While he lay thus, being prodded and examined by the public, he suddenly remembered that he had half a dollar in his pocket. With all that money it didn't matter so much about the compensation; up jumped our friend like an india-rubber ball, and in a second he had vanished in the crowd, who stood open-mouthed, gazing after the "dead"
man.
Our speed on this cruise was regulated as nearly as possible so that there might be about 100 nautical miles between each station, and I must say we were uncommonly lucky in the weather. We made two fairly parallel sections with comparatively regular intervals between the stations; as regular, in any case, as one can hope to get with a vessel like the Fram, which really has too little both of sail area and engine power. The number of stations was 60 in all and 891
samples of water were taken. Of plankton specimens 190 were sent home. The further examination of these specimens in Norway will show whether the material collected is of any value, and whether the cruise has yielded satisfactory results.
As regards the weather on the trip, it was uniformly good the whole time; we had
a good deal of wind now and then, with seas and rolling, but for the most part there was a fresh breeze. In the south-east trade we sailed for four weeks at a stretch without using the engine, which then had a thorough overhauling. At the same time we had a good opportunity of smartening up the ship, which she needed badly. All the iron was freed from rust, and the whole vessel painted both below and above deck. The decks themselves were smeared with a mixture of oil, tar and turpentine, after being scoured. All the rigging was examined. At the anchorage at Buenos Aires nearly the whole ship was painted again, masts and yards, the outside of the vessel and everything inboard, both deck-houses, the boats and the various winches, pumps, etc. In the engine-room everything was either shining bright or freshly painted, everything hung in its place and such order and cleanliness reigned that it was a pleasure to go down there. The result of all this renovating and smartening up was that, when we fetched up by the quay at Buenos Aires, the Fram looked brighter than I suppose she has ever done since she was new.
