William Dampier and the Burning Islands of Melanesia

William Dampier and the Burning Islands of Melanesia

A tweet from Jenni Barclay about a Pirate Scientist gave me an excuse to visit the newly opened reading rooms in the Bodleian’s Weston Library..

William Dampier was a seventeenth century pirate, and later maritime adventurer, whose several books of ‘Voyages and Discoveries’ make for fascinating reading. In 1699, he set sail in HMS Roebuck to try and find Terra Australis, a mythical ‘southern continent’. His journey took him past the Cape of Good Hope to the north-western coast of New Holland (now Australia), and then on to Timor, New Guinea, and New Britain. On the way back, he only got as far as Ascension island, in the Atlantic, before his ship sprung a leak and had to be abandoned. His crew were rescued some weeks later by a party of British naval ships on their way to Barbados.

In the preface to his 1703 book ‘A Voyage to New Holland..’ he writes ‘The world is apt to judge of everything by the success, and whoever had ill fortune will hardly be allowed a good name. This, my Lord, was my unhappiness in my late expedition in the Roebuck, which foundered thro’ perfact age near the island of Ascension. I suffered extreamly in my reputation by that misfortune..’

Despite his pessimism over the loss of the ship, and his failure to reach Terra Australis, the expedition was a great success as a ‘voyage of discovery‘. Dampier’s book has some lovely descriptions of active volcanoes that he encountered to the east of Timor island – part of what we now call the Banda Arc – and of others along the north coast of (Papua) New Guinea, part of what is now known as the Bismarck Arc. Several of his reports of volcanoes that he encountered are the earliest written records of activity.

Banda

Banda island volcanoes – likely Wurlali and Banda Api. ‘No 6. A burning island to the East of Timor shows thus. Distance 4 leagues.’ ‘No 7 Thus shows 2 of the Bandy islands. Distance 12 leagues.’          1 league is 3 nautical miles.  Bodleian ms. 8 S 43 Jur

 

On 13 Dec 1699, the Roebuck sailed from Babao, east past Timor towards New Guinea.  On December 27th ‘ we saw the burning island.. It lies in lat 6 deg 36 minutes. It is high but small. [The top] is divided in the middle into two peaks,  between which issued out much smoak’. This is most likely Wurlali volcano,  on Damar island, Indonesia. Later they sailed past another burning island, most likely Banda Api. Then around the northern coast of present day Papua New Guinea, they encountered several volcanoes of the New Guinea arc. Wally Johnson has interpreted this portion of Dampier’s trip in his recent book  Fire Mountains of the Islands, and identified several of Dampier’s unnamed ‘burning islands’.

On the 24 and 25th March 1700, Dampier spent some time watching an eruption, now thought to be of Ritter Volcano which lies in the straits between Papua New Guinea and New Britain

At ten o clock I saw a great fire, blazing up in a pillar, sometimes very high for three or four minutes..  In the morning I found out that the fire we had seen was a burning island, and steered for it.’ ‘March 25th the Island all night vomited fire and smoak very amazingly and at every belch we heard a dreadful noise like thunder and saw a flame after it. The intervals between its belches were about half a minute. Some more, some less, neither were these pulses of eruptions alike, for some were but faint convulsions in comparison of the more vigorous yet even the weakest vented a great deal of fire, but the largest made a roaring noise and sent up a large flame 20 or 30 yards high, and then might be seen a great stream of fire running down to the shore‘.

Little more is known of Ritter volcano until 1888, when it collapsed catastrophically in a non-eruptive submarine avalanche.

There is a wonderful interactive map of Dampiers voyage in Google Maps. Wally Johnson’s Fire Mountains of the Islands (ANU Press, 2013 – available online) is a splendid resource on the volcanoes of Papua New Guinea and the Solomon islands, and their eruptive histories. There is a also a short piece on the eruption history of Ritter island in the Cooke-Ravian Volume of Volcanological Papers (editor, R. W. Johnson), Geological Survey Of Papua New Guinea Memoir 10, 115-123 (1981).

Volcano Top Trumps: the Online Game

VTT

After some months of testing and refining, a free-t0-use online version of Volcanoes Top Trumps has been launched by Winning Moves. This should greatly extend the reach of Volcanoes Top Trumps – which is a fun and educational game about volcanoes that has spun off from the NERC ESRC funded project ‘STREVA‘ – Strengthening Resilience in Volcanic Areas. Why not play the online game, and then let us know what you think of it!

There’s (volcanic) dust in the archives

There’s (volcanic) dust in the archives

There’s not much that beats the thrill of discovery.. particularly when it turns up in your own backyard.  This summer, I have been on the hunt for records and reports of the 1902 eruptions of St Vincent, a lush volcanic island in the Eastern Caribbean. There are indeed many reports from this eruption, carefully documented in official records from the time. But, more surprisingly, there are samples – and many of them in the UK: packets, vials and boxes of ash; chunks of rock and more, in museum collections and archives in both the Natural History Museum, and at the British Geological Survey. Here is just a snapshot of some of the incredible samples from the British Geological Survey Archives.

From the BGS archives

Four vials of volcanic ash – all collected on Barbados. The smallest vial is of ash from the 1812 eruption of St Vincent. The three other vials are samples of ash that fell on Barbados during eruptions between May 1902 and March 1903.

Along with the samples are the original envelopes in which they were sent, and handwritten notes documenting the sample: priceless tools, when you want to look back at an eruption that took place over 100 years ago.

1902 Barbados ash

1902 Barbados ash sample sent to Horace Woodward, who was in charge of the Geological Survey’s office in Jermyn Street, London, at that time – which included the Museum of Practical Geology. Memo reads ‘Dust from Mt Soufriere St Vincent, collected on the deck of the SS ‘Statia’ lying at Barbados, 90 miles distant, travelling against a strong S E wind and covering everything to the depth of 5 inches. 1903′.

Some of these samples are timed and dated, and can be linked to particular phases of the eruption. Here is one example – of the ash that fell during the opening stages of the eruption on Barbados.

First hour

‘Volcanic dust collected at Barbados during the night May 7-8 1902. This spec. fell during the first hour’. Collected by WG Freeman, a botanist at the Imperial Department of Agriculture for the West Indies in Barbados.

Other samples can be used to map the distribution of ash and coarser samples that fell across St Vincent – here’s an example of a ‘gravel’ grade sample from Rosebank on St Vincent.

1902 ash

1902 tephra sample collected on St Vincent by  Henry Powell, Curator of the Botanic Station on St Vincent. ‘Sample of volcanic sand which fell at Rosebank (Leeward) on night of 3rd and morning of 4th Sept. 1902’

Among the most amazing discoveries, are examples of damage to economically valuable plants – this one, a sample of Breadfruit leaf that was damaged during the latter stages of the eruption in March 1903.

‘A leaf of the Bread Fruit Tree (Artocarpus incisa) gathered in St Vincent about 12 miles from the Soufriere and showing perforation caused by volcanic stones etc.’ Collected by WG Freeman in 1903.

Together, these sorts of samples will allow us to go back and investigate what was actually happening during the eruption, in a way that is rarely possible, even for modern events.

Summer Reading – H is for Hawk

Much of my time is consumed with reading, but it is almost always for a purpose: essays, assignments, proposals, drafts of papers, re-drafts of papers, papers for classes, for review..  This almost always means reading fast, with a goal: to measure, assess, hone, distil, critique and rewrite.  Often, it means hacking through tangled and cumbersome layers of scientific prose, to reveal the central narrative.

Then, for in a few days in midsummer, I get the chance to rediscover reading for pleasure: immersion in a book that grabs hold of your imagination and translates you to another place and another time. This year, my summer reading has got off to a cracking start with ‘H is for Hawk’.

Helen Macdonald's H is for Hawk, alongside TH White's Goshawk.

Helen Macdonald’s ‘H is for Hawk’, alongside TH White’s ‘The Goshawk’

 

‘H is for Hawk’, written by Helen Macdonald and published by Jonathan Cape, is a dizzying, dazzling read that defies its rather sober classification (‘Nature Writing/Biography’). The book weaves together a deeply personal story of grief and loss, with the rediscovery of life lived through the training of a young goshawk. In places, the staccato text crunches like the twigs strewn across a forest floor; in others, it soars like the circling hawk, magnificent, alert to the slightest movements below. It contains some wonderful writing on nature, capturing the very essence of the countryside in just a few words, alongside some moving reflections on bereavement and the way that death changes in a moment the lives of the living, and our relationships with what was present and is now past. In parallel, and wrapped up closely with the training of her young goshawk, Helen Macdonald explores the life and writing of TH White, a teacher and writer of Arthurian novels who wrote of his own struggle to train a goshawk in the 1930’s.  The result is a book that works on several levels, and would reward re-reading: a beautiful and captivating read.

H is for Hawk by Helen Macdonald, published by Jonathan Cape, 2014. ISBN 9780224097000

The Goshawk by T.H. White. Reprinted 2007. ISBN 9781590172490

Update – in November 2014, Helen Macdonald was awarded the 2014 Samuel Johnson Prize for ‘the best non fiction book published in the UK’ for H is for Hawk.

 

Friday Field Photo – St Vincent, 1902

Roseau Dry River, St Vincent, 1902. Photo by Tempest Anderson, published in his book  Volcanic Studies in Many Lands (1903).

Today’s field photo is by Tempest Anderson, of the ‘Roseau Dry River flowing with Boiling Mud’, a picture taken in the aftermath of the May 1902 eruptions of the Soufrière of St Vincent.  The full published caption explains the origins of this boiling mud – a phenomenon we now call a lahar:

This is a small stream in the Wallibu Basin. When the water undermines the banks and the hot ashes fall into the river, the stream is often dammed up, and the giving way of the obstruction is associated with a great discharge of boiling mud. In one of our ascents of the Soufriere, we had crossed the Rozeau Dry River without difficulty in the morning when the weather was fine, but heavy rain had fallen before our return in the afternoon, and the river was full of boiling mud, coming in gushes, as shown in the picture. After some trouble our men cut down two trees which had been killed by the eruptions, and made a bridge by which we crossed. The banks show the characteristic erosion by the rain rills.’

 Lahars are a very common feature at volcanoes, and they may often continue to be triggered by strong rainfall events for months or years after the eruptive activity has ceased.

 Tempest Anderson was an opthalmologist by profession, and also an inveterate traveller and photographer. He accompanied  John Flett to the Caribbean to document the eruptions on St Vincent and Martinique, in 1902, and a selection of his photographs can be found on the website of the Yorkshire Museum. The Soufrière of St Vincent is the centrepiece of the London Volcano project, which runs from 9-13 June.

How NOT to write to an editor

Over on the Nature Methods blogs site, there are some interesting posts with advice for authors on how to prepare cover letters, rebuttal letters, appeal letters and the like.

Here’s an example of ‘how NOT to write to an editor‘, based on a recent experience of mine. I shall let the author remain anonymous, but my hunch is that this is not an isolated example of this sort of behaviour, and I’d be interested to hear of any similar experiences.

The background.

A while ago, I declined to send for review a paper which I was handling as editor. The paper was submitted as a Review Article but, as I explained to the author, the manuscript was not ready to be considered for publication since it was pretty much only a review of their own work, without proper reference to current work in the wider field. I suggested to the author that this would be something to address, and returned my decision through the usual journal manuscript-handling route. The author subsequently responded to the entire editorial body of the journal, before escalating their grievances further, and for this reason I regard their correspondence as public. Here is what happened next..

Response 1 from the author [edited].

I appreciate your efforts to provide a rather detailed explanation of the basis for your decision to decline publication of my manuscript. I would .. like to respond to some of your comments as I believe such a response might be helpful to you.  I am the individual responsible for demonstrating the feasibility of this [hypothesis] and I have made almost all of the developments. That is simply a matter of historical fact. Those with the capability should have tried to refute the idea and, if unable to do so, the idea should be cited. When a malevolent, but influential, coterie decides to ignore a specific development, it places that coterie, and those who subscribe to that behavior, at risk. The risk is not being able to progress in science.  You have no legitimate basis to expect [me] to cite or debate “recent work on the nature of [X]” as virtually all of the published work .. is based upon [an idea for which] there is no independent corroborating evidence.

One does not progress in science by making models based upon assumptions, but rather by discovering fundamental quantitative relationships.  Science is all about telling the truth. To say that I have failed to [cite recent work] is not correct, which makes me wonder about your underlying motivation for declining publication of this work.  Sometimes it seems as if the geoscience community, especially Americans and more recently Europeans, try to avoid any mention of science that disagrees with their pet models. I have seen that behavior repeated over and over. In declining publication of the submitted manuscript, you aid and abet that behavior.

Perhaps you are unaware that science progresses, not by arraying seemingly agreeing evidence, but by discovering inherent failures. To a large extent the geoscience community is playing at science, making nonsense models based upon assumptions, suppressing mention of real scientific advances, and patting each other on the back.  Sadly, your behavior seems to doom the journal to be an organ of mediocrity. If you are unable to be a real scientist, why play at science?

Since  this response didn’t actually appeal the decision, I left it at that.

Two weeks later, I received the following message from the author, copied to several senior staff in my University.

Subject: Allegation of Misconduct and Academic Malfeasance..

[Over the years] most of my work has been intentionally ignored, subjected to misrepresentation, and often unwarrantedly suppressed, while the geoscience community wastes vast amounts of money making models based upon arbitrary assumptions in lieu of making discoveries. The matter at hand is about just such an incidence of unwarranted science suppression justified solely by false statements.

Evidence is presented below to support the allegation that Pyle (1) aided and abetted a concerted effort to conceal from the scientific community, Government science-funding officials, and the general public, certain specified scientific advances, published in world-class journals, and (2) made a series of false statements to justify (1). One consequence of said alleged actions is to cheat those individuals and institutions, including taxpayers, whose monies support scientific research in areas adversely affected by said concealment. In the broader context, said allegations of unwarranted science suppression stand in contradiction to principles of academic integrity that should be the minimum expectation. [The] rejection decision without legitimate basis resembles and appears to become part of concerted efforts to suppress, conceal and misrepresent [my] published work…  This is a pattern of activity which, I submit, has the consequence of defrauding those entities that fund scientific research. It is a pattern of activity that I believe should be investigated by authorities.

 I believe that it would be wrong either to ignore or to whitewash the present matter. I propose that .. Professor Pyle might consider making a concerted effort to counter said unwarranted ignoring, misrepresenting, and attempts at suppression of my work. For example, he might submit a Theme Issue proposal [to a journal on this topic]. He might write a review article for [a mainstream] journal.  He [might] also organize a special session on the subject for [an international] meeting.  Moreover, Professor Pyle might benefit through attaining a deeper understanding of geoscience and how to make important scientific discoveries.

I leave my readers to come to their own conclusions, but I’d like to make three points:

1 – in most journals, the role of the editor *is* to make judgements about what to publish, and what not to publish. There is nothing malevolent about this – there is whole world of journals out there, in a competitive market place and authors are free to shop around to find the best place for their work.

2 – journals all have formal mechanisms for replying to editors, and asking for decisions to be reconsidered. The author made no attempt to explore any of these avenues before embarking on a completely irrelevant path of escalation.

3 – if you do wish to engage an editor, then perhaps best not to start off  by being patronising; and certainly better not to engage in tactics that could be interpreted as harrassment, bullying or threatening behaviour.  If people are ignoring your work, perhaps it’s not their fault, but yours?

In any case, these protests about suppression of ideas are  fatuous: at the time of submission, the paper was already available to read in ArXiv; and the day after receiving my decision, the author submitted a version of the paper to another journal, where it has since been published.
