Banda Island and the Banda Sea marine gardens

The Banda volcano (Gunung Api or Fire Mountain) is a perfectly conical mountain that rises 656 meters above sea level, and is about 3 kilometres wide. The nutmeg island of Banda has been a key location in the spice trade and historical eruptions have been recorded there since the late 1500s. These have been relatively low-level, although there have been the occasional larger eruptions with the lava flow reaching the coast as can be seen on this photograph.

After 97 years of dormancy a violent eruption shook the Banda islands in May 1988 as Gunung Api exploded. A column of ash billowed 3 kilometres into the air and tremors were felt every few minutes. On the day of the eruption, people began moving to further islands, eventually about 10,000 people of the 16,000 population living in the Banda islands were evacuated during the eruption, which finally ended in August 1988. The photograph below shows the Dutch church in Banda with the erupting Gunung Api and the huge ash column in the background.

Marine scientists have monitored the coral colonization on 3 locations adjacent to the lava flow and in just 5 short years, the hardened andesitic flow has supported over 120 species of coral. A larger diversity and abundance than the adjacent reef not affected by lava.

Now, 30 years later, coral growth around the lava flows from Gunung Api not only matches, but exceeds the development that normally takes coral formations over 70 years to achieve, making it the most rapid growing coral in the world. The reason is probably the heat or mineralization generated by the lava flow.

Alfred Russel Wallace’s publication of ‘The Malay Archipelago’

This week we celebrate the 150 year anniversary of the publication of Alfred Russel Wallace’s book, The Malay Archipelago. This wonderful book is an account of the eight years he spent in British Malaya and the Dutch East Indies collecting natural history specimens, including his discovery of the biogeographic boundary between Asia and Australia which came to be called ‘The Wallace Line’, his descriptions of the region between Asia and Australia which came to be known as ‘Wallacea’, and the recognition from his studies of the fauna that Australia had collided with Asia.

The Malay Archipelago is undoubtedly the classic work on the flora, fauna and peoples of the area which is now called Malaysia and Indonesia. Based largely on four field journals which Wallace kept during the eight years he spent there between 1854 and 1862, it ranks as the greatest travel book on the region and for its analysis of the geographic distribution of animals, it is one of the most important natural history books of the nineteenth century.

The main purpose of Wallace’s travels, as he states in the preface to his book, was to obtain natural history specimens for his private collection and to sell duplicates to museums and amateur naturalists through his agent in London. Altogether he collected an astonishing 125,660 specimens of natural history, mainly beetles, butterflies and birds from across the archipelago.

The Malay Archipelago was published in London on 9 March 1869 in two volumes of 1500 copies and it quickly sold out. A second edition of 750 copies came out in October that year and edition after edition followed.  A German translation came out in 1869 and a Dutch translation in 1870 and it is believed that the book has never been out of print.

The Malay Archipelago was dedicated to Charles Darwin and he must have received an advance copy because he wrote to Wallace on 5 March 1869. ‘ I was delighted at receiving your book this morning. The whole appearance and the illustrations with which it is so profusely ornamented are quite beautiful … As for the dedication, putting quite aside how far I deserve what you say, it seems to me decidedly the best expressed which I have ever met.

Darwin dedication

Wallace begins The Malay Archipelago with this evocative description of the region:

If we look at a globe or a map of the eastern hemisphere we shall percieve between Asia and Australia a number of large and small islands, forming a connected group distinct from those great masses of land, and having little connection with either of them. Situated upon the equator, and bathed with the tepid water of the great tropical oceans, this region enjoys a climate more uniformly hot and moist than almost any other part of the globe, and teems with natural productions which are elsewhere unknown. The richest of fruits and the most precious of spices are here indigenous. It produces the the giant flowers of the Rafflesia, the great green-winged Ornithoptera (princes among the butterfly tribes), the man-like orang-utan, and the gorgeous birds of paradise. It is inhabited by a peculiar and interesting race of mankind – the Malay, found nowhere beyond the limits of this insular tract, which has hence been named the Malay Archipelago.

What is interesting is that nowhere in The Malay Archipelago does Wallace mention his famous ‘Letter from Ternate’ or his essay ‘On the Tendency of Species to Depart Indefinitely from the Original Type’ which he wrote in three days and sent to Charles Darwin from Ternate in March 1858. Stating that he “hoped the idea was as new to Darwin as it was to himself and that he believed it would supply the missing factor to explain the origin of species”. Of course the idea was not new to Darwin, although he had never published his theory,  and it was Wallace’s letter which precipitated the joint presentation to the Linnean Society in July 1858, while Wallace was still in the Dutch East Indies, of his and Darwin’s common theory on the Origin of Species.

The 50th Anniversary of this momentous event was celebrated in 1908 when Alfred Russel Wallace was presented the Darwin-Wallace Gold Medal. The President of the Linnean Society, in welcoming the delegates and guests on this occasion, said:—

“We are met together today to celebrate what is without doubt the greatest event in the history of our Society since its foundation. Nor is it easy to conceive the possibility in the future of any second revolution of Biological thought so momentous as that which was started 50 years ago by the reading of the joint papers of Mr. Darwin and Dr. Wallace, ‘On the Tendency of Species to form Varieties’ and on the ‘Perpetuation of Varieties and Species by Natural Means of Selection’ …

Darwin and Wallace not only freed us from the dogma of Special Creation, a dogma which we now find it difficult to conceive of as once seriously held —they afforded a natural explanation of the marvellous indications of Design which had been the great strength of the old doctrine…

Dr. Alfred Russel Wallace, We rejoice that we are so happy as to have with us today the survivor of the two great naturalists whose crowning work we are here to commemorate. Your brilliant work, in Natural History and Geography, and as one of the founders of the Theory of Evolution by Natural Selection, is universally honoured and has often received public recognition, as in the awards of the Darwin and Royal Medals of the Royal Society, and our own medal in 1892. Today in asking you to accept the first Darwin-Wallace medal, we are offering you of your own, for it is you, equally with your great colleague, who created the occasion which we celebrate today.”

Swimming with Whale Sharks in Papua

The map below shows our October 2018 voyage with Coral Expeditions from Biak to Darwin. There is no doubt that the highlight  of the voyage was swimming with whale sharks in Cenderawasih Bay in Papua.

October 2018 facebook


The whale shark is the largest non-cetacean animal in the world with an average length of 10 metres and weighing 9 tonnes. They are actually sharks although they have tiny teeth because they are filter feeders like whales, living on plankton and small squid or fish. The whale shark inhabits warm tropical or temperate waters, is pelagic and lives in the open sea, but seasonal feeding aggregations occur at many sites around the world including Cenderawasih Bay shown in the centre of this map of Indonesian Papua.

Cendrawasih Bay

We fly from Darwin to Biak where we join the Coral Discoverer and sail south into Cenderawashih Bay (Bird of Paradise Bay) looking for the Bagans (floating fish traps) to which the whale sharks are attracted by an expansive seafood menu.



We leave the Coral Discoverer on the smaller Xplorer vessel and approach the Bagan with some of our group already in the water.

Is that me on the right? Look for another whaleshark in the background left. It was a fantastic morning and we had nine whalesharks around us including an infant.

WS3Oh My!  What a big mouth you have. Think of Jonah and the whale. The small fish attached to the bottom of the whale sharks live off whatever they clean off their skin.


Thank you to my fellow Coral Expedition explorers for their underwater photographs


To complete a wonderful day we went ashore at Kwatisore to meet the villagers, to be entertained with some traditional singing and dancing, and to browse their market

The next voyage to Papua, Cenderawasih Bay  and the Spice Islands with Coral Expeditions will be in December 2019 and January 2020 aboard the Coral Adventurer. Please go to their website for more details.

Ian Burnet talking at ‘Better Read than Dead’

Where Australia Collides with Asia – the latest book review

Where Australia Collides with Asia - IHS poster 2

Ian Burnet, with his thirty years’ personal experience in the culture and history of the area, gives competent, intelligent and entertaining accounts of the voyages of the three main protagonists whose discoveries transformed our understanding of the processes of evolution and species formation. Specifically, he discusses Joseph Banks, Charles Darwin and Alfred Russel Wallace, after whom the Wallace Line is named. The book is superbly illustrated with eighteenth and nineteenth century paintings, etchings, drawings and maps, some of which hail from the diaries of the explorers. It also features modern photographs of animals, birds and locations. Extracts from Banks’, Darwin’s and Wallace’s diaries and books also form a substantial part of the narrative and are used to great effect by Burnet to enhance and illustrate his story.

The books style is somewhat journalistic, giving us ‘just the facts’. Considering his knowledge of this part of the world, it is a shame that the author did not enlist his own experiences to influence the narrative, by allowing the reader to see the area through an explorer’s or scientist’s eyes. While he does a very good job of telling the reader what happened, showing us a little more would, perhaps, have enhanced the tale.

However, this remains a very good book. It has been thoroughly researched and contains a useful bibliography enticing readers to pursue the subject further. It is well written, informative and engaging, all of which are essential in a work aimed at a general audience. I found much to admire and to keep reading without effort. The quotations have been well chosen and enhance the narrative. The characters of Darwin, Wallace and Banks are fleshed out nicely and their stories are presented in a sensible chronological order. I can see how Burnet’s account could encourage anyone interested in evolution, exploration or natural history to read Darwin’s Voyage of the Beagle and the two volumes of Wallace’s Malay Archipelago for themselves. In this sense, Burnet has done a very good job indeed.

‘Friends in Australia’ – a message from Sutan Sjahir, the Prime Minister of the newly declared Republic of Indonesia, November 1945.

On 17 August 1945 and two days after the Japanese surrender, Soekarno and Hatta unilaterally declared Indonesia’s Independence and became the first President and Vice President of the Republic of Indonesia.

Soekarno Proclamation

Brothers and Sisters All!

I have asked you to be in attendance here in order to witness, an event in our history, of the utmost importance.

For decades we, the People of Indonesia, have struggled for the freedom of our country- even for hundreds of years!

There have been waves in our actions to win independence, which rose, and there has been those that fell, but our spirit still was set in the directions of our ideals.

Also during the Japanese period, our efforts to achieve national independence never ceased. In this Japanese period it merely appeared, that we leant upon them. But fundamentally, we still continued to build up our own powers, we still believed in our own strengths.

Now has come the moment, when truly, we take the fate of our own actions and the fate of our own country into our own hands. Only a nation bold enough to take its fate into its own hands, will be able to stand in strength.

Therefore last night, we had deliberations with prominent Indonesians from all over Indonesia. That deliberative gathering was unanimously of the opinion that NOW has come the time to declare our independence.

Brothers and Sisters:

Herewith we declare the solidarity of that determination.

The Dutch East Indies government in exile was based in Brisbane, Australia and the Dutch prepared ships to carry arms, munitions and troops to re-occupy Indonesia and re-establish their colonial state.  Indonesian seamen living in voluntary exile in Australia during the war,  together with other Asian seamen, and Australian Waterside Workers,  imposed a ‘black ban’ on loading Dutch ships bound for Indonesia in Australian ports. The efforts of the Indonesian seamen, the support of ordinary Australians for Indonesian Independence and the actions of the waterside workers who, maintained the  ‘black ban’, caused Dutch efforts to quickly re-occupy Indonesia to falter.

The Australian government  did not support the Dutch in their efforts to re-establish their colonial state and instead took the side of the new Indonesian nation. The Australian Government under Prime Minister Chifley refused to break the ‘black ban’ on the grounds that it was a dispute involving a foreign nation and their own subjects.

In November 1945, Sutan Sjahir, the Prime Minister of the newly declared Republic of Indonesia sent this message of thanks to the Australian people, who by their actions, helped support Indonesia’s independence at the most crucial point in its history.


‘Friends in Australia, I am unknown to most of you and yet I call you my friends. Most of you, who really are the workers, who refused to load the Dutch ships with arms and munition, which would be used against our Republic. The thousands, who are holding demonstrations, to protest against the onslaught against our independence, the thousands of you, who sympathise with our struggle for our freedom. You are all my friends.

When the war broke out, I was still a Dutch exile on the island of Banda. I heard of Australians being landed on the island of Ambon and the island of Timor. They came there to fight the Japanese, to defend their home country. Australians fought in Malacca, and  in Sumatra, Australians fought in Java. Australians fought all the way back from North Africa to Papua to defend their homeland. An invasion of Australia by the Japanese was threatening. Then things took a turn. Australians and the Americans fought the Japanese back through the jungles and over the seas to their homeland. Australia had a narrow escape. I think Australians are tough fighters. But, I admire most of all, that, you did not fight for territorial or political nor economical gains. You, Australians fought so bravely, because you wanted to defend your freedom. You are fighters for freedom, all the way long from North Africa to Australia up to Japan.

I think, that is why you ought to understand our position now, we are fighting for our freedom!

 With you, we want a world where freedom of the people and freedom of men are really safeguarded. With you, we want to stand to together against all enemies of freedom. If we have achieved our aims, become strong and independent country, we assure you, you need not fight anymore in Sumatra, in Java, in Borneo, Ambon, Timor, for freedom. We ourselves, we will withstand all onslaught on freedom of our country. And so defend, your freedom too, you will be able to keep your sons at home, working for the welfare of your people and for the welfare of humanity.

We know, that your country has come out of the war as an important industrial country. We are still an agricultural country. We need your engines and other industrial products.  I suppose, you can use our agricultural products. Therefore, we can and we will certainly, establish close relations as good neighbours, exchanging the goods of our countries.’

The Dukono Volcano on Halmahera

When our Coral Expeditions cruise arrived in the town of Tobelo on the northwestern arm of the island of Halmahera in October 2018, the Dukono volcano was erupting ash. This should not have been a surprise since research shows that the volcano has been erupting almost continuously  since 1978.


The Dukono volcano as seen from the Coral Discoverer

A rift in the earth’s mantle has caused a sea floor spreading zone between the islands of Sulawesi and Halmahere, causing subduction and related volcanic activity along the edge of both islands. There are sixteen volcanoes on the Halmahera volcanic arc, many of which are still active, and an equal number along the Sangihe volcanic arc.


This seafloor map shows the central ridge, like the larger mid-Atlantic ridge, formed by the intrusion of oceanic magma. This intrusion causes spreading of the sea floor and the related subduction zones are shown by the seafloor trenches developed on each side of the central ridge . The water filled sediments that are subducted into the earths interior then become superheated, melt the surrounding rocks, and cause the volcanic activity.

Google Map

The related volcanoes can be best seen on this topographical map of Halmahera which shows a line of volcanoes formed along the western side of the island, including the clove islands of Ternate, Tidore, Moti and Makian which are offshore.


The Dukono volcano is only 10 km from the town of Tobelo. While we were there it was continuously erupting ash, but fortunately the wind was blowing to the northeast and away from the town.
