COSMIC NEUTRINOS

14 Jun

This is fascinating. For those, like me, who find it difficult to conceptualize these particles, they are described as: subatomic, invisible: electrically neutral and passing through space without interference, They travel in straight lines and are almost undetectable. In fact, in seconds, tens of billions pass through our bodies. They are created by radioactive decay such as takes place in the sun  — most neutrinos apparently emanate from the sun.

Antarctica boasts a neutrino detector, ‘Ice Cube’. It is a telescope 1000s meters below the ice. It houses sensitive devices, strings of censors each with 60 sensitive light detectors. As I understand it, as neutrinos come hurting through, they occasionally collide with the nuclei of ice atoms. The collision produces a blue flash that detectors record and, since neutrinos travel in straight lines, the direction they have come from can be determined.

In April, two neutrinos, cunningly called Bert and Ernie, were detected with high enough energy to suggest they had come from the cosmos rather than from our atmosphere i.e. outside our solar system. This was a first. More have been since.

The aim now is further investigation directed towards that region of space in the hope of getting increase understanding of what is going on in the cosmos.

Professor Sienicki’s paper on Scott’s ‘suicide’

17 May

On April 1, I wrote a comment on my blog about Professor Krzysztof Sienicki’s paper on ‘The Weather and its Role in Captain R.F. Scott and his Companions’ Deaths’ which seeks to prove that on their return, Scott and Bowers decided on suicide and fraudulently doctored their temperature recordings to suggest that the team experienced unusually cold weather. I received a comment from Karen May, a polar researcher with a detailed knowledge of Scott’s last journey and from Kristoffer Nelson-Kilger, a member of the Sienicki team.

I published Kristoffer’s full reply also my comment on this on May 1. Kristoffer mentioned a book ‘Captain Scott’s Fatal Antarctic Expedition: Slanted Truths – Centennial Account’, which will, no doubt, contain more of the same.

Kristoffer wrote also to Karen May making essentially the same points. She has sent me her reply, dated 14 May.  She defends Scott against this denigration. It is long and detailed but I feel her comments are so detailed and of such general interest that I am hosting her reply on my blog

Karen May’s reply to Kristoffer Nelson-Kilger:

Dear Kristoffer,

Thank you for your comments and your response. Since you have responded online, I would like to go more deeply into my objections. A number of assertions by both you and Professor Krzysztof Sienicki run counter to the primary evidence available. Prior to your publication, I believe that it would be in your best interests to take the following points into consideration.

Firstly, it isn’t my first paper (“Could Captain Scott have been saved?”) that you should examine in regard to these notions of Scott and Bowers having killed themselves, it’s the second paper, “A kind of suicide? Errors and misconceptions in Roland Huntford’s account of the last days of Scott’s polar party.” I urge you to read that second paper (co-authored with George Lewis), and examine the case it makes for Scott and his men coming home to national honours and the chance of seeing their loved ones again.

You write, with regard to Scott’s suicide: “Both Sienicki and I believe that lack of hope of getting back was not the motive, but for Scott at least, the motive was fear of powerful enemies in Britain who had previously gotten away with slandering him and Lt. Royds over the latter’s meteorological records from the Discovery expedition.”

Your argument appears to be that Scott killed himself because some people once slandered his meteorological results. Again, I would ask you please to read the second paper “A kind of suicide?”, and also have a look at the people to whom Scott wrote his farewell letters – distinguished naval men such as Admiral Sir Lewis Beaumont, Vice-Admiral Sir Francis Bridgeman and Vice-Admiral Sir George Egerton. These were the superiors who mattered in Scott’s life, those for whom he had worked and who had given him active support in his career. It isn’t feasible that Scott could have killed himself over the “slander” which could have been perpetuated against his results by a few unknown scientists when he, a naval officer, had rock-solid naval prospects and connections back at home.

These “slandering” scientists would have had absolutely no influence at all over the progress of Scott’s naval career. Indeed, I would ask you please to place all of this in the proper historical context: with the British celebrations which would have ensued upon Scott’s triumphant return home in 1913 as the “honourable” conqueror of the South Pole, who would even pay any attention to scientists picking fault with Scott’s meteorological research? I would strongly urge you to come to a deeper understanding of Scott’s situation (and Bowers’, and Wilson’s, and Oates’) before you make such allegations.

Please also remember that Scott, Wilson and Bowers were real human beings with a proven track record of caring for their families. Please attribute to these men the same love for their families as you possess for your own. If you do, you will doubtless see that your hypothesis of “deliberate slow suicide, planned long in advance and abandoning their loved ones to the possibility of penury” is frankly untenable.

You write: “As for reasons 1-3, Scott and Bowers’ actions run counter to their previous lives, but that does not make me discard what I know happened: the falsification.”

I would venture to suggest that you are starting with biased premises from the very beginning – namely, that this could not possibly have been error, and could only have been calculated “falsification” with a view to suicide. You dismiss the most obvious conclusions: that the instruments were faulty (more on this later), or that these were exhausted men and that, when people are exhausted, mistakes are likely to happen. This can be seen during 20 February 1912 in Scott’s journals, when he mistakenly states that both 19 and 20 February were “Mondays” and then proceeds to write his journal one day “out” until his death! (You can see this for yourself in Max Jones’ edition of the diary, OUP paperback, p.399-400, or see Glenn M. Stein’s longer evaluation on the Antarctic Circle, here: http://www.antarctic-circle.org/dates.htm.) Your theory of deliberate suicide would seem to depend upon the premise that Scott was incapable of making errors, but surely the “two Mondays” of 19 and 20 February would indicate that he was certainly capable of making unintentional errors at this stage.

Some other things for you and Professor Sienicki to consider:

1)      My co-author, George Lewis, is keen for you to bear in mind that Captain Oates was still healthy and going strong during the month of February, and that furthermore from 25 February Scott, Wilson, Oates and Bowers were managing mileage in double-figures once more after the previous setbacks. Oates’ feet had not yet been frostbitten. Things looked good for the polar party, and, as Scott remarks himself on that date, “We are naturally always discussing possibility of meeting dogs.” So to support your argument, you will need to explain what Oates’ position was in late February. Did Oates, still fit and with everything to live for, decide to give up in late February alongside his tent companions? If so, why did he not just leave the tent on 2 March when he found his feet were frostbitten? Why did he put himself through the torture of a further two weeks’ manhauling on frostbitten feet if he had already decided to die? The recorded chronology would suggest that he wanted to live, and that he still held out hope that the dogs would be coming.

2)      You need to explain more clearly whether Wilson was part of this “suicide pact” or not. This is the man who had written in his youth “[I]t is no sin to long to die, the sin is in the failure to submit our wills to God to keep us here as long as He wishes” (Seaver, Edward Wilson of the Antarctic, 1933: 72). What Wilson is stating here is that a wish to die is sometimes understandable, but it is a sin against God if one chooses to act on such an impulse and deliberately end one’s life. If you read Wilson’s last letters, you will see that his Christian faith is secure to the end: “It is God’s will and all is for the best” is a phrase that occurs in last letters both to his wife and his parents, and to his parents he writes “God knows I have no fear on meeting Him – for He will be merciful to all of us” (“The Last Letters”, ed. Lane, Boneham and Smith, 2012: 48-49, 50-51, 53). Can you explain how and why this deeply religious man would have decided to commit deliberate suicide – a decision which, in his own words, would have been “a failure to submit his will to God” and which would arguably have consigned his soul to Hell? (The same objection could be made in the case of Bowers, another sincere Christian.)

3)      Professor Sienicki states that “a specially constructed sling thermometer with a wooden handle was broken by Lt. Bowers on March 10, 1912” (Sienicki 2010: 2).  I have consulted the Expedition’s Meteorological Tables (edited by Simpson, 1923) and I found that on p.642, Bowers acknowledges in his meteorological log, in writing, on 10 March 1912, that his thermometer was broken. Bowers specifically writes the phrase “Thermometer broken”.  He does not state that he himself broke the thermometer, but simply that the thermometer was “broken”. From that date, 10 March, until the end of observations on 12 March, Bowers continues to comment on the weather but offers no further temperature readings.

Now, please place these facts in the context of your “Bowers suicide theory”. Bowers, you state, deliberately and with malice aforethought falsified his temperature readings to give the polar party an alibi for their self-willed deaths. But, if this were the case, why would Bowers write down the words “Thermometer broken” into his record? If he was relying on the deliberate falsification of readings as an alibi, why would he then cast all those previous readings into doubt by announcing, as a matter of written record in the log, that as of 10 March the thermometer was “broken”? Surely the announcement that the thermometer was “broken” signals to the reader the clear possibility that it was now defective, and that its previous recordings might not have been reliable – and, since this is clearly the case, does this not destroy your theory of Bowers’ supposedly carefully-calculated and malicious-minded “alibi”? If Bowers were falsifying temperature readings in the last weeks, then obviously he would have continued to falsify them. A fabricator would not have made any written record that his thermometer was “broken”. A fabricator would not have cast doubt on his thermometer at all.

Professor Sienicki states “Captain Scott’s party used high quality thermometers, calibrated at Kew Observatory, London. Sling and dry-bulb thermometers were used with precision” (Sienicki 2010: 2).  However, Professor Sienicki provides no evidence to back up the assertion that they were “used with precision”. These were meteorological instruments manufactured in the Edwardian era, and both of them would have been subjected to innumerable jolts and stresses during this journey. Either these thermometers were carried on the bodies of the man-haulers themselves or (more probably) they were strapped onto their sledges: these thermometers travelled across hundreds of miles of crevassed ice, sastrugi and other uneven surfaces to the Pole and back again. One of these thermometers was eventually declared “broken” by Bowers, and it seems highly unlikely that the other can be regarded as 100% infallible.

I stated in my earlier comment on this blog that if these temperature results were such a variation from the norm as to be incredible, then it was easier to believe in the instruments being defective, or the readings being accidentally confused, than in this deliberate suicide plot. The undeniable evidence of Bowers’ declaring his own thermometer “broken”, and making this a matter of written record, would tend to support my initial reaction.

Now, to other points you raise. You state:

Furthermore, by Feb. 27 at the earliest to Mar. 1 at the latest, Scott could-from his point of view-safely determine that the dogs were not coming: see the written orders he had given them that you cited in your above article, then cross reference that with Scott’s diary entries of Feb. 27 and Mar. 1-2, and remember that the latitude of the Mid Barrier Depot (that Scott is 31 miles S of on Feb. 27 and at on Mar. 1) is 81° 35′ S.”

How exactly could Scott have deduced that the dog teams’ failure to show between 27 February-1 March was cast-iron evidence that they would not be coming at all? This is pure hindsight on your part: Scott could not possibly have known during this period that all hope was lost. In Scott’s very last journal entry he writes “I do not think we can hope for any better things now”: that was dated 29 March, a month later. It appears that only in late March did Scott finally reconcile himself to the fact that the “better things” – the hope of salvation by the dog teams – would not materialize.

Curiously, you suggest that Scott and Bowers gave up hope as early as 7 February. You state: “The reason why I too cannot accept that Bowers and Scott got into your “private conversation” on Feb. 27, 1912 is because-as I have already pointed out-Scott manufactured his first food shortage on Feb. 7, 1912, so if your conversation did serve as the catalyst, it would have to have been before that day.”

You wrote to Dr Williams: “Evidence that they were stage managing their exit can be found as early as February 7, when Scott manufactured a food shortage, finding the rations short by 1 day and declaring that they hadn’t increased rations. In doing so, Scott deliberately ignored his own diary entry of January 29, where he declared that they would increase rations on “the day after tomorrow,” which would be January 31, and ignored his own diary entry of February 1, where he listed the ration increase as 1/7. 7 times 1/7 equals 1, so if they started the increased ration on January 31, this would place Scott’s party short of rations by 1 day at the beginning of lunch on February 7.”

You state that Scott “ignored his own diary entry”: however, if this were a deliberate suicide gambit, a consciously-crafted narrative made with clear-sighted malice aforethought, then why did Scott leave the previous diary entries of 29 and 31 January to stand and contradict him? Why did he not simply cross out or rub away those extracts, making them illegible, and stick to the new “stage-managed” story? The obvious interpretation is that this is not “stage-managing”. Scott increased rations on 31 January, then forgot he had done so a week afterwards and panicked in his diary entry of 7 February. What you portray as a “manufactured food shortage” looks to me like a simple confusion. What you and Professor Sienicki have discovered is evidence of error, a self-contradiction made by an exhausted man in extreme circumstances. You choose to read this as evidence of Scott’s intent to commit suicide; I consider this a melodramatic interpretation of something that can equally and more simply be explained as a mistake.

You state: “Then you are going to have to explain why and how Scott’s thermometer (which recorded daily midday near surface temperatures) malfunctioned at the same time to give abnormally low temperatures, and explain why it was later tested and nothing found wrong. “

You are going to have to prove that your last statement is actually true. Let us go back to Professor Sienicki’s article, in which he states that “The only thermometer left after March 10, 1912 was Captain [Scott’s] personal spirit thermometer which was found by a search party in 1913. Charles Wright tested its calibration back in London. Test results proved this thermometer’s accuracy within a tenth of a degree” (Sienicki 2010: 6).

However, the reference Professor Sienicki gives to back up this conclusion is Susan Solomon’s book “The Coldest March” (2003), specifically page 289, and what Sienicki writes does not reflect at all what Solomon writes on her page 289. There Solomon writes,

“Though the specific thermometer carried by the polar party was broken, as documented by Bowers in the meteorological log book, Wright took other spirit thermometers back to England and retested their calibrations. He found changes of a few tenths of a degree or less in those instruments, and he wrote to Simpson in India describing those tests” (Solomon 2003: 289).

(By the way, the curious reader need not simply take my word for this: Solomon’s exact wording can be quickly and easily checked with the “Search inside this book” facility available for “The Coldest March” on amazon.co.uk, and Professor Sienicki’s 2010 paper “The Weather and its Role in Captain Robert F. Scott and his Companions’ Deaths” can be located online with a quick Google search.)

Any reader can see quite plainly that there is a significant reversal from the account of Wright testing not Scott’s thermometer but a number of “other spirit thermometers” from the expedition (Solomon’s account) to Professor Sienicki’s scenario of Wright’s testing a single remaining expedition thermometer, which just happened to be Scott’s own  thermometer (Sienicki’s account). “Changes of a few tenths of a degree” has also been erroneously altered to “within a tenth of a degree”: this is minor, however, in comparison to the fundamental misattribution of the thermometers. It would appear that Professor Sienicki has made an unfortunate and serious misreading of Solomon’s evidence. Where is the evidence that Wright ever subjected Scott’s own thermometer to testing in 1913, or indeed at any other time? Please quote your source exactly, with page numbers, so that I can check this for myself.

The fact that Professor Sienicki cited Solomon’s page 289 as evidence for his statement about “Captain Scott’s thermometer”, when Solomon on that page gives evidence which directly contradicts this statement, shows how easy it is for a scholar to make an unintentional, yet serious, mistake in the reading of evidence. I can only hope that, in the light of this accident, you and Professor Sienicki will be appropriately charitable in your evaluation of the results of these exhausted men in extreme conditions.

The burden of proof rests on you to establish that you and Professor Sienicki are on solid ground in your allegations of deliberate suicide, and the following is a minimal list of the criteria you are going to have to fulfil to ensure that your argument holds water:

1)      You need to find clear evidence that Wright or anyone else tested Scott’s own thermometer after the tragedy and found it in perfect working order

2)      If you do find clear evidence that Wright or anyone else ever tested Scott’s own thermometer and found it in perfect working order, you need to ascertain that Scott’s thermometer was kept absolutely untouched and inviolate from its discovery in November 1912 until tests in 1913 or later, and that no-one could possibly have fixed it before these tests

3)      You need to prove that this type of thermometer could not possibly have been capable of a period of erroneous readings, followed by automatic self-correction at a later date

4)      The reader will expect readings from other thermometers of that type and a thorough assessment of how accurate/prone to error they were by modern standards. (For example, would any modern meteorologist go on record as stating that they would rely on Edwardian-era thermometers today in preference to the latest equipment?)

Since so much of your theory rests upon the infallibility of this one thermometer (and the impossibility of Scott’s having made any kind of error in taking readings from it), I believe that you will need to present a detailed analysis of the specific instrument itself (brand, date of manufacture, etc.), incontrovertible proof that it was indeed tested after the polar journey and found infallible, the way in which it was used and how readings would have been taken. Interestingly, Solomon, on page 289 of “The Coldest March”, states that both Apsley Cherry-Garrard and Teddy Evans wrote to Simpson in 1914 to confirm that they had taken the precaution of keeping their thermometers in the shade when taking their readings: this alone would indicate that this kind of thermometer was a delicate instrument, and that oversights by the recorder during the taking of those readings could lead to errors.

You write: “Right now, suicide pact remains the only plausible candidate for a motive; of course, Sienicki and I will take any new possibilities into consideration.”

I do hope that you will examine the evidence again with an open mind. If you are going to suggest “a suicide pact” as the only possible interpretation of events, you will need far stronger evidence than “These men recorded unlikely temperature variations, using delicate Edwardian-era instruments which had undergone a great deal of repeated stress (and one of which was later explicitly declared “broken” by Bowers) and taking these readings when in a state of utter physical exhaustion”. I would urge you please to make full allowance for the possibility of accident, error and circumstances outside of the polar party’s control before you begin talking of “motive” and “suicide pacts”.

Thank you for taking the time to read this. I am sure that you and Professor Sienicki will address all these issues in your forthcoming publication “Captain Scott’s Fatal Antarctic Expedition: Slanted Truths – Centennial Account”.

Best wishes,

The Royal College of Surgeons of England

7 May

The Royal College museum has a large collection of teeth including samples of leopard seals, dating from the early 20th century. So the college was able and provide small samples of these to the New South Wales School of Biological, Earth and Environmental Sciences, who are studying how climate change has altered the diet of the Antarctic Peninsula top marine predators. The stable isotopes of nitrogen and carbon in teeth act as a marker for the diet of the animal, so changes in the diet can be assessed

 

The WEST COAST of the Antarctic Peninsula has been one of the most rapidly warming places on earth. The EAST COAST has remained reasonably stable. This warming has an effect on the Antarctic ecosystem. The leopard seal is amongst the  top predators in this region, therefore, one of the first animals that might show a change in diet. Indeed this seems to have happened; on the west coast it appears the leopard seal is no longer top predator, it now eats krill (a krillavor!). Krill stocks are diminishing, so the future of leopard seals in this area is uncertain. At present the females are significantly smaller than they were thirty years ago.  This change has not happened on the east coast. It is interesting to speculate if some leopard seals have changed their hunting areas to follow their preferred prey.

This interesting piece of research may be due to global warming. It would be interesting to know if killer whales, an efficient top predator, also shows evidence of dietary change.

 

 

 

Professor Sienicki’s assertions about Scott’s ‘suicide’

1 May

I have received correspondence from Professor Sienicki’s team concerning my recent blog on the subject of The Weather and its Role in Captain F. Scott and his Companions’ Deaths. What follows is their letter, followed by my response.

I recently came across your blog post “The Weather and its Role in Captain F. Scott and his Companions’ Deaths, by Professor Krzysztof Sienicki”. I have been helping Prof. Sienicki with a book he has been writing, and thus felt the need to correct several errors in your blog post.

First, you make the mistake of stating Prof. Sienicki made a neural network across the Barrier. This is not correct: what he did was take weather data and ran it through an artificial neural network. You also failed to note the similarity of temperatures at Elaine (at the foot of the Beardmore Glacier) and Schwerdtfeger (near One Ton Depot) AWS stations he noted. These two AWS stations are on Captain Scott’s route. The conclusion is tangible: weather conditions along Captain Scott’s route would have been similar from Elaine onward.

With that in mind, you then fail to note Sienicki’s noting of the First Relief Party’s weather record in support of his thesis. The First Relief Party’s weather record can be found in Simpson’s Vol. III, Table 78, available here: http://archive.org/details/meteorology03simp Compare the Table 78 record with the Scott party’s record, while keeping in mind Sienicki’s observation that Scott’s temperatures were daily mid-day temperatures, and the conclusion is obvious.

Then you miss the point of Sienicki’s pointing out of Leonard Huxley’s falsification of the 1st edition of Scott’s Last Expedition’s temperatures and Jones’ papering over of them. His point is about their actions, not Scott’s. Sienicki pointed out more than an aggregated miscalculation by Solomon; he also pointed out her data dragging by misrepresenting the Scott party’s daily mid-day near surface temperatures after March 10 as daily minimums, and logical fallacies.

Finally, in your citing of Scott’s letter to Sir Bridgeman, you make the mistake of failing to note that the Bridgeman letter has for a long time been partially available in Scott’s Last Expedition, and you incorrectly indicate that the recently released content in the Bridgeman letter includes your quote. The actual recently released content is: “I want you to secure a competence for my widow and boy. I leave them very ill provided for, but feel that the country ought not to neglect them.”

In addition, with regard to your insinuation that the Scott party had neglected the sick, this is certainly in my view true regarding P.O. Evans, but it should be noted that Scott was not entirely consistent in regard to Oates being dead weight. See Scott’s diary entry of March 10 for these quotes: “In point of fact he [Oates] has none. Apart from him, if he went under now, I doubt whether we could get through…At the same time of course poor Titus is the greatest handicap.”

Your assertion that dying was not part of Scott’s plan betrays that you have made an all too common mistake: taking what Scott wrote at face value. Prof. Sienicki and I believe that dying was part of the Scott party’s plan. Evidence that they were stage managing their exit can be found as early as February 7, when Scott manufactured a food shortage, finding the rations short by 1 day and declaring that they hadn’t increased rations. In doing so, Scott deliberately ignored his own diary entry of January 29, where he declared that they would increase rations on “the day after tomorrow,” which would be January 31, and ignored his own diary entry of February 1, where he listed the ration increase as 1/7. 7 times 1/7 equals 1, so if they started the increased ration on January 31, this would place Scott’s party short of rations by 1 day at the beginning of lunch on February 7.

These details and much more will be detailed in Prof. Sienicki’s book, Captain Scott’s Fatal Antarctic Expedition: Slanted Truths-Centennial Account, due to be released this year.

Thanks for considering,

Kristoffer Nelson-Kilger

REPLY

My concern is not on Professor Sieniki’s techniques, but on the interpretation of his findings.

He analysed weather data at various sites over The Barrier for a prolonged period. During this time the pattern of temperature change at different sites followed each other. Scott’s recordings of nearly a century earlier were at variance to Sienicki’s measurements (lower) and furthermore, did not follow the pattern of other explorers in the early 1900s. Professor Sienicki therefore thinks they were falsified.

He concludes that Birdie Bowes and Scott had decided that self destruction was the best way out of their situation and that, by altering the temperature records, they would strengthen Scott’s claims in his messages that the conditions the British team encountered were extraordinarily bad.

He then goes on to involve Huxley in a cover up, stating that where Scott had recorded positive temperatures, Huxley had changed them to negative. He states that Max Jones said the alterations could have been a mistake and that the renowned scientist, Susan Soloman is mistaken in her interpretation of the data.

You say that Sienicki proved that Scott and Bowers falsified evidence. He has done no such thing.  He has shown that the recorded temperatures were dramatically at variance from the norm. But he himself found temperatures approximating to Scott’s low readings in 1985.

The main point of my objection however is that whole tenure of the article is that there was a suicide pact. I think this most unlikely.

If Scott had lived he would not have been held responsible for the deaths of those he had lost, (Scott lost two men on the Discovery Expedition, Amundsen lost men in 1903-6 and 1918-25, Mawson lost his two companions in 1912-13. Shackleton lost men in his Ross Sea party. The last three were honoured). Scott had ‘played the game’ and this would have been respected by the British who honoured Teddy Evans who was sent home with scurvy. He would have been financially secure. He would have been promoted.

Birdie Bowers was a committed Christian and meticulous in his recordings. It would have gone against a lifetimes practice to falsify them.

Wilson, another committed Christian, who longed to return to his wife and family and, in the tent with them day and night as they weakened, does not get a mention. Did this intrigue, which would affect him so fatally, take part in the tent alongside their valued friend, somehow excluding him from their decisions?

The proposed scenario seems most unlikely and I do not think we are going to progress further on this one.

BRITISH ANTARCTIC SURVEY

23 Apr

The B.A.S. mounted a very interesting programme for polar enthusiasts last week.

We were shown examples of Antarctic plants (hairgrass and pearlwort), mosses.  lichens and liverworts, animals dead and live (brought back form the continent), the impressive map work, including the interesting topography of the mountains in Antarctica well below the snow line and we were given history of B.A.S. and its contribution to science.

I was fascinated by the ice cores. There are samples which reflect conditions well over 100.000.000 years ago. I was particularly interested to find how they measure the gaseous content of these samples. As I understand it the samples are placed in a vacuum, smashed to release the gases and the levels are then measured. Carbon dioxide has shown marked variation over the centuries but in recent times the level has shot up and up.

We were also shown a film about the discovery of the location of the wreck of the ‘Terra Nova’ Scott’s last ship, which was scuttled off Greenland in the 1943. I wonder what they will do with it!

The Weather and its Role in Captain F. Scott and his Companions’ Deaths, by Professor Krzysztof Sienicki

1 Apr

 

 

I have just had my attention drawn to this paper published in 2010 which suggests that Scott and ‘Birdie’ Bowers ‘doctored’ the minimum temperatures recorded on the Barrier between February 27 – March 19, 1912, so as to dramatise the weather conditions. Professor Sienicki suggests that the party made a deliberate decision to die, a decision made before food and food supplies were finished or the men’s strength exhausted.

The argument is based on his recording of minimum temperatures from 1985 -2009, by a neural network across the Barrier. These he compared with historical recordings made by expeditions in the early 1900s, including the Discovery and Nimrod expeditions. He found a relationship between the minimum temperatures at different locations at the Ross Ice Shelf, i.e. a gradient at one station was followed by a similar change at another station. For example, though recordings at  McMurdo  (near the sea), are about 20° higher than those deep on the Barrier, the essential pattern of  change, from early February till 19 March over the years1993-2009, mirrored each other significantly, so the particularly low temperatures recorded by Scott’s party, (and, furthermore, not recorded by other historical expeditions over this period), are significant, unique and, he concludes, questionable.

The technique is carefully validated and Professor Sienicki dismisses the suggestion that Scott’s thermometer malfunctioned. He concludes that Scott and Bowers distorted the temperature documentation to exaggerate the real weather conditions.

He then goes on to say that Leonard Huxley edited and arranged the first edition of Scott’s journals (which gave negative temperatures), and actually shows Scott’s recorded temperatures from November 3, 1911 till 25 February 1912. These reveal that Scott’s recordings in Fahrenheit were positive. Sienecki quotes Max Jones in saying that ‘an establishment conspiracy covered up Scott’s failings, creating a hero by the careful editing of his sledging journals….’ hardly the work of the long-dead Scott. Whether these changes (from positive to negative degrees Fahrenheit) were deliberate has been debated, but this is hardly down to Scott. Sienicky also quotes Susan Soloman, who says that the average temperature recorded by Scott were 10-20° below respective modern data, and that one year (1988) recorded a minimum temperatures close to the 1912 reported data. He confirms with his own data that 1988 was exceptionally cold, but states that Soloman has miscalculated the degree of severity. However, Sienecki’s confirmation of near surface temperatures close to that reported by Scott, does not convince him that the Scott party really experienced unusually low temperatures. To this it is reasonable to comment that it is impossible to say that they definitely did not.

Professor Sienicki has made an impressive study of long- term Barrier temperatures, but his conclusion that Scott and Bowers deliberately falsified their records is unproven.

The recent publication of Scott’s letter to Sir Francis Bridgeman saying that they could have got through ‘if they had neglected the sick’ (possibly true), gives further weight to the conclusion that dying, for whatever reason, was not part of Scott’s plan.

 

 

 

 

 

 

NADFAS

21 Mar

I am being assessed as a speaker for the National Association of Decorative and Fine Arts, an organisation with branches all over the country. This is quite an experience: you have to give your presentation to a large audience where an anonymous observer assesses the effort. I hope that mine, which was to a lovely group, FiSH in Barnes, South London. went reasonably well. If it is approved of I go on to an interview.

Because of the emphasis on decorative and fine arts I have to consider a new topic. I found that the Antarctic heroes I speak about, with the exception of Wilson and Shackleton, do not exactly answer to this requirement, so I am preparing my talk on  von Herkomer . He did woodcutes, engravings, water colours and oil paintings. He painted the poor and the rich (in number)! So, plenty of material which I hope will suit NADFAS.

I am to be a speaker on Queen Mary 2. This too is an excitement. Four talks in six days!

vonHerkomerThe more you learn about a subject the more interesting it becomes and so it seems with von Herkomer.

I was surprised that he was suggested to follow Ruskin as Slade Professor at Oxford by no less a person than Ruskin himself. Herkomer was a young man when, in 1878, he met the 59 year old, frail Ruskin. Ruskin was apparently charmed by Herkomer’s exuberance (and his zither playing!). Herkomer, in his turn was impressed by Ruskin’s wide reaching conversation and his (unexpected to me), charm of manner. (Herkomer was eventually appointed as Slade Professor in 1885.)

In 1879 Ruskin sat for a portrait by Herkomer, The interest in this is firstly, it is an excellent portrait and secondly, the way Herkomer approached his subject was so different to Ruskin, that it is remarkable that Ruskin tolerated the experience (and supported the Slade Professor plan.) Whereas Ruskin made minutely observed outlines and details and then added colour, Herkomer covered the paper rapidly with a wash in grey or ochre then sketched his subject in charcoal, working over this with a long-haired brush. Ruskin found Herkomer’s ability to produce a likeness from such a hastily drawn sketch, amazing.

Ruskin thought photographs did not flatter him, but he liked the portrait. He wrote that it was full of character though ‘not like him in the ordinary sense’ and ‘the first that has ever given what good may be gleaned out of the clods of my face’

RANULPH FIENNES TRANS-ANTARCTIC WINTER JOURNEY

1 Mar

Ranulph Fiennes must be gutted that he has had to give up his trans-Antarctic winter journey attempt before actually setting off in the Antarctic, because of his frost-bitten fingers.

But he had no choice. He has already lost several finger tips with frostbite which occurs when the temperature is so low that blood vessels constrict and  the flow to the affected part is significantly reduced. If this reduced blood flow persists the tissues die. and the surface skin becomes black. Gangrene may follow if the deeper tissues are affected.

The condition needs prompt treatment to limit the extent of the damage. The return of blood flow is painful.

I’m sure that the team will continue successfully with the many scientific aims that have been planned, also the big fund raising for charity.

The last time a man pulling expedition was made in the Antarctic was when Edward Wilson, ‘Birdie’ Bowers and Apsley Cherry-Garrard crossed Ross Island in 1911. The journey was very short by comparison with Sir Ranulphs expedition, but memorably awful.

Shackleton

14 Feb

Shackleton is really hotting up in the news now, a year before the centenary of him setting off on his most famous expedition, the “Endurance” expedition at the very beginning of WW1

But it is the “Nimrod” expedition that is in the news recently in relation to items left in the hut when the team left their base in a hurry to pile onto the  ship. Cases of Whisky and brandy have been recovered amongst other things.

Shackleton came from a family that was teetotal and as a young man, did not drink ; later he overcame this inhibition rather easily. He noted the benefits of alcohol on the “Discovery” expedition and realised that on his  own expedition his 14 companions would need alcohol for relaxation; apart from anything else they had the terrible Antarctic winter to get through.  He needed to encourage camaraderie. He took 25 cases of  10 year malt whisky to his base. Called ‘Rare Old Highland Malt Whisky’ it was especially prepared for British Antarctic Expedition of 1907. The malt was 47 percent proof, this gave it a low freezing point and  is how a number of cases survived the 100 years since it was stored in the crawl space under the hut.

Contents from the 3 retrieved cases have been analysed by Scottish Distillers Whyte and Mackey, who took over the original firm who provided the whisky. It is said to be in perfect condition. To obtain a bottle of the original malt is impossible for mere mortals, but Whyte and Mackay’s analysis has allowed them to reproduce the 100 year old flavour at, apparently, £100 per bottle

I must buy one!
