Advance Base was no reckless whim. It was the outcome of four years of planning. The original idea came out of my first expedition to the Antarctic, and was an indirect by-product of my interest in polar meteorology. Of all the different branches of science served by a soundly constituted polar expedition (on the last we served twenty- two branches) none to the popular mind has a more practical value than meteorology. The framer whose livelihood comes from crops, the people whose stomachs are kept full by these crops, the speculators who gamble in them, the industrialist whose factories depend upon the farmer's purchasing power, the sailor on the seas — all these and others, even to the casual holiday tourist, have a vital stake in weather. But few of them appreciate the extent to which the poles enter into their local schemes.
Most of us have a schoolboy's understanding of the theory of simple circulation: a cold current of air flowing inexhaustibly from the poles to the equator, a counter current of warm air returning poleward above it; and the two together creating the breathing of the globe. The extent to which the poles influence the weather is still a subject for speculation. Some authorities go so far as to say that each pole is the true weather maker in its respective hemisphere. This latter belief has been formulated in Bjerknes' theory of the polar front, which undertakes to explain atmospheric circulation in terms of the effects produced by the interaction of masses of polar-cooled air, the so-called polar fronts, with the masses of warm equatorial air into which they intrude.
Although a knowledge of polar meteorology is indispensable for enlightened long-range forecasting, we really know very little about it. And, because of the need for more information about the general laws of circulation, the first concern of an expedition leader is to see that his meteorological department is strongly staffed. This obligation has been earnestly met by most expeditions. The results, nevertheless, have been meager; for Antarctica has been under scientific investigation for less than half a century; and, so far as weather data are concerned, the bulk of the knowledge is represented by the work of perhaps a dozen well-found expeditions.
For a continent having an estimated area of 4,500,000 square miles, this is not much of a showing. Or so it seemed to me. In the course of my first Antarctic expedition, I was struck by the thought that the most valuable source of meteorological data was still left untouched. What data existed had for the most part been collected at fixed bases on the Antarctic coast or on islands adjacent to the coast; by ships exploring contiguous waters; and by field parties poorly equipped for research making fast summer dashes inland. Meteorologically, the interior of Antarctica was a blank. No fixed stations had ever been advanced inland; no winter observations had ever been made beyond the coast; and the fragmentary data collected by sledging parties covered only the comparatively mild summer months. Yet, inland, beyond the moderating influence of the seas which surround the continent, was the coldest cold on the face of the earth. It was there one must look for typical continental conditions. And it was there that I proposed to plant Advance Base. There, where weather is manufactured. The data accumulated by a station like Advance Base when correlated with data gathered simultaneous at Little America, ought to throw a highly revealing light on the facts of atmospheric phenomena in high southern latitudes. Why should a civilization as technologically alert as ours continue to tolerate a situation that allows ruinous storms, kindled long before at remote storm centers, to break without adequate warning upon the civilized parts of the world? Only recently Mr. Willis R. Gregg, chief of the United States Weather Bureau, predicted the establishment in the polar regions of robot observers which would flash data by wireless to stations in lower latitudes. That way, meteorologists could watch conditions as they develop in the main amphitheaters of meteorological action, and plot their charts accordingly.
I rather wish I had thought of that myself, because Advance Base was intended to be the pilot station for a polarwide system of similar outposts except that it was to be manned by flesh and blood instead of a mechanical brain untroubled by cold and darkness and memory. Our original plan was decidedly a daring one. In the preliminary discussions with Bill Haines, then, as on the second expedition, my Senior Meteorologist, I never pretended that the idea was more than speculative. In other words — great stuff, if we could do it. Where we finally decided to aim for was the foot of the Queen Maud Mountains. Even with that, we realized that we were probably over-reaching ourselves. It meant hauling tons of supplies some 400 miles across the crevasse-ridden Ross Ice Barrier and relying upon tractors whose capacities on Barrier surface would have to be determined by guess and by God.
In all aspects, particularly the psychological, the risks surrounding the project were very real. Whoever should elect to inhabit such a spot must reconcile themselves to enduring the bitterest temperatures in nature, a long night as black as that on the dark side of the moon, and an isolation which no power on earth could lift for at least six months. Now, against cold the explorer has simple but ample defenses. Against the accidents which are the most serious risks of isolation he has inbred resourcefulness and ingenuity. But against darkness, nothing much but his own dignity.
In the kind of station we had in mind the normal risks of a polar base would be intensified a thousand fold. The difficulties would be great. The amount of supplies that could be advanced would be small, and, therefore, only very few men could occupy it. The men would be jammed together at arm's length in a tiny shack buried in the snow. Wind and cold would keep them from ever leaving it for more than a few hours a day. Change in the sense that we know it, without which life is scarcely tolerable, would be nonexistent. The party would be dedicated to an iron routine. The day would be the repeated pattern of the hour; the week, the repeated pattern of the day; and one would scarcely be distinguishable from the other, even as an interval in time. Where there is no growth or change outside, men are driven deeper and deeper inside themselves for materials of replenishment. An on these hidden levels of self-replenishment, which might be called the pay levels of philosophy, would depend the ability of any group of men to outlast such an ordeal and not come to hate each other.
My idea was that three men — preferably two weather observers and a radio operator — should man the Base. The difficulties of hauling supplies into the Antarctic interior made three the maximum; and the risks, especially those of a psychological order, argued forcefully against less than three. Three is a classic number. Three men would balance each other like the legs of a tripod. With three men as compared to two, the chances for temperamental harmony seemed infinitely increased, since, in the nature of human relations, one man would constantly be present in the stabilizing role of a neutral judge, a court of appeal. Instead of hearing one voice everlastingly and seeing one face and being confronted with one pattern of habits and idiosyncrasies, a man would have two aspects and personalities constantly facing him.
Under such conditions it doesn't take two men long to find each other out. And, inevitably, this is what they do, whether they will it or not, if only because once the simple tasks of the day are finished there is little else to do but take each other's measure. Not deliberately. Not maliciously. But the time comes when one has nothing left to reveal to the other; when even his unformed thoughts can be anticipated, his pet ideas become a meaningless drool, and the way he blows out a pressure lamp or drops his boots on the floor or eats his food becomes a rasping annoyance. and this could happen between the best of friends. Men who have lived in the Canadian bush know well what happens to trappers paired off this way; and, mindful of these facts, I resolved from the beginning not to have Advance Base a two-man project.
Even at Little America I knew of bunkmates who quit speaking because each suspected the other of inching his gear into the other's allotted space; and I knew of one who could not eat unless he could find a place in the mess hall out of sight of the Fletcherist who solemnly chewed his food twenty-eight times before swallowing. In a polar camp, little things like that have the power to drive even disciplined men to the edge of insanity. During my first winter at Little America I walked for hours with a man who was on the verge of murder or suicide over imaginary persecutions by another man who had been his devoted friend. For there is no escape anywhere. You are hemmed in on every side by your own inadequacies and the crowding pressures of your associates. The ones who survive with a measure of happiness are those who can live profoundly off their intellectual resources, as hibernating animals live off their fat. Occupied by three men of this sort, Advance Base should not be too difficult a place. So I reasoned, in all events.
During the months that followed the return of the first expedition the idea was continually challenging my imagination. Since the idea wouldn't down, I made a serious study of the practical possibilities. Well in advance of the mobilization of the second expedition late in 1933, four of us started working on the Base. One man was Victor Czegka, a Warrant Officer assigned to me by the Marine Corps. Another was Paul Siple. Both had served on the first expedition and knew the problems to be overcome. Czegka's job was to design the shack which would be the Base, and Siple's was to study and collect the essential materials required for it. The actual building of the shack was done by Ivor Tinglof, a cabinetmaker, in a Boston loft. And when the Jacob Ruppert, flagship of my second expedition, put out from Boston in October, 1933, she carried secreted in the hold the cunningly contrived
