THIS is the first of.a series of volumes dealing with the Meteorological data accruing from the labours of the Expedition. It was not until the year 1923 that financial pro­ vision was made to cover 4;he cost of tabulation and reduction of the records. This was rendered possible through the good offices of Mr. H. A. Hunt, the Director of the Commonwealth Meteorological Service, who has fathered the Meteorological work of the Expedition from the inception of the enterprise. The tabulated data is so voluminous that it has been found convenient to publish it in three separate volumes namely Vols. Ill, IV, & V of Series B. The present Volume (Vol. Ill) incorporates the records of the Macquarie Island Station. Volume IV deals with the data of the Cape Denison Station, Adelie Land. Volume V includes first, the records of the Queen Mary Land Station ; secondly, the Meteorological loggings of the S. Y. Aurora made on three Antarctic and two Sub-antarc­ tic cruises ; thirdly, meteorological notes made on numerous sledging journies from the Antarctic Bases. The discussion of the records thus tabulated and printed will constitute a fourth volume. When organising the Expedition I found that nobody was more seized with the importance of extending meteorological observations in the Australasian Antarctic and Sub-antarctic than Mr. H. A. Hunb. The possible influence of that region upon the climate of the more temperate regions to the north was a problem of real interest to Australians and New Zealanders. There was already available much knowledge relating to the Koss Sea region, but practically nothing whatever of the immense region to the west, which is not only, nearer, but on account of its more westerly situation, is better placed in regard to Australia and New Zealand to exert influence over their climate. The Ross Sea region is in higher latitudes and on account of the prevailing west to east drift of anti-cyclonic disturbances, the disturbances thereabouts, in so far as exerting an effect upon the meteorological conditions in temperate latitudes, would be expected to exert a maximum influence only in regions to the east of New Zealand. In view of the importance of extending meteorological knowledge of the Southern Regions, therefore, Mr. Hunt heartily co-operated in the programme, and strongly recommended the establishment on Macquarie Island of a meteorological recording station with a wireless installation capable of despatching daily reports to Melbourne, 4 AUSTRALASIAN ANTASCTICT EXPEDITION. These reports were to be incorporated in the daily weather forecasts, with a view to ascertaining the value of such a station in that regard. Through Mr. Hunt, general instruc­ tions for meteorological records were drawn up and certain members of the expedition given short training in the work. The Expedition's meteorological programme, beside establishing a recording station on Macquarie_ Island^ and providing for loggings on board the ship, included the establishment of several scattered stations on the up-till­ then unknown sector of the Antarctic Continent between Cape Adare and Gauss Berg. -The securing of contemporaneous data from these widely scattered locations was a feature of importance which was further enhanced by the fact that Scott's Terra Nova Expedition and Amundsen's Fram Expedition to the Ross Sea were also operating during the early portion of our effort. In view of the immediate importance of the Macquarie Island Station, Mr. Hunt loaned one of his officers, Mr. G. F. Ainsworth, to act as meteorologist at the Island Station. Subsequently, on the expiration of the Expedition, Mr. Hunt decided to take over and continue that Station. Accordingly, after two years of never-failing vigour and duties splendidly executed, Mr. Ainsworth was relieved early in December, 1913, and his place taken by Mr. H. Power who, with two others, continued the Station for the Common­ wealth Meteorological Service. At the end of November, 1914, Mr. Power was relieved by Mr. A. C. Tulloch, the relief being effected by the Commonwealth Fisheries Steamer Endeavcur. On account of the war, so great difficulty was now experienced in securing a vessel for the annual relief of the Station that it was decided to temporarily close it. Ac­ cordingly Mr. A. C. Tulloch and his two campanions were withdrawn in December, 1915. OB the departure of Tulloch's party, the Living Hut with certain equipment and the wireless huts and their equipment and masts were left with the expectation of use at some 'future time. But the war dragged on so long and the financial strain became so great that all thoughts of continuing the Station faded away and has never again been realised. As the additional records secured by Mr. Hunt's Department during the regime of Messrs. Power and Tulloch are of very great value in the discussion of the Expedi­ tion's meteorological data, they have been made available and incorporated herewith. It is with deep regret that we recall the death of Harold Power who was lost on -board the Endeavour which disappeared with all hands on the return voyage from Macquarie Island, after landing Mr. Tulloch. The vessel and the entire crew disappeared in those tempestuous seas without leaving any trace. In that disaster Meteorological Science not only lost an enthusiast in Mr. Power but also the detailed observations accumulated by him throughout the year of his office which records were on board with him. All that remains of that period are the daily summaries communicated by him per wireless telegraph to the central Commonwealth Meteorological Office. At the Main Base Station in Antarctica, which was located at Cape Denison, Adelie Land, the meteorological instruments were erected as spor as possible after landing the METEOBOLOGY—MACQUARIE ISLAND STATION. 5 party. My previous experience in Antarctica was very beneficial in securing the best lay-out of the instruments to meet the exigencies of the special circumstances presented in so remarkable a climate. After the routine of recording was well established, Mr. C. T. Madigan was thereafter appointed Chief Meteorologist which post he occupied with great credit throughout the two.years occupation. The Meteorological Records were conducted with great system and perfect regularity throughout that time. The info m­ ation obtained is unique in that it deals with an area which, it would appear, is the most windy spot on the earth's surface. This is obviously owing to the situation of the Station on the seaward-sloping margin of an elevated circumpolar ice plateau of continental proportions. Under these circumstances, the incessant wind at low temperatures, the routine of observations and attention to the instruments was rendered particularly difficult and at times hazardous in the case of the more distant instruments. A general idea of the conditions experienced and of the difficulties which faced the meteorologist are recounted in " The Home of the Blizzard," the popular story of the Expedition. What is certain in my mind is that like difficulties have never yet been experienced in the same degree at any other meteorological station.

Patricia Margaret Millar Date ii Abstract Photographers made a major contribution to the recording of the Heroic Era of Antarctic exploration. By far the best known photographers were the professionals, Herbert Ponting and Frank Hurley, hired to photograph British and Australasian expeditions. But a great number of photographs were also taken on Belgian, German, Swedish, French, Norwegian and Japanese expeditions. These were taken by amateurs, sometimes designated official photographers, often scientists recording their research. Apart from a few Pole-reaching images from the Norwegian expedition, these lesser known expedition photographers and their work seldom feature in the scholarly literature on the Heroic Era, but they, too, have their importance. They played a vital role in the growing understanding and advancement of Antarctic science; they provided visual evidence of their nation’s determination to penetrate the polar unknown; and they played a formative role in public perceptions of Antarctic geopolitics.

    THE JAMES CAIRD SOCIETY JOURNAL Number Six Antarctic Exploration Sir Ernest Shackleton MARCH 2012 1 Shackleton and a friend (Oliver Locker Lampson) in Cromer, c.1910. Image courtesy of Cromer Museum. 2 The James Caird Society Journal – Number Six March 2012 The Centennial season has arrived. Having celebrated Shackleton’s British Antarctic (Nimrod) Expedition, courtesy of the ‘Matrix Shackleton Centenary Expedition’, in 2008/9, we now turn our attention to the events of 1910/12. This was a period when 3 very extraordinary and ambitious men (Amundsen, Scott and Mawson) headed south, to a mixture of acclaim and tragedy. A little later (in 2014) we will be celebrating Sir Ernest’s ‘crowning glory’ –the Centenary of the Imperial Trans-Antarctic (Endurance) Expedition 1914/17. Shackleton failed in his main objective (to be the first to cross from one side of Antarctica to the other). He even failed to commence his land journey from the Weddell Sea coast to Ross Island. However, the rescue of his entire team from the ice and extreme cold (made possible by the remarkable voyage of the James Caird and the first crossing of South Georgia’s interior) was a remarkable feat and is the reason why most of us revere our polar hero and choose to be members of this Society. For all the alleged shenanigans between Scott and Shackleton, it would be a travesty if ‘Number Six’ failed to honour Captain Scott’s remarkable achievements - in particular, the important geographical and scientific work carried out on the Discovery and Terra Nova expeditions (1901-3 and 1910-12 respectively).
