From the end of December 2016 to the beginning of February 2017 I travelled in Philippines, Malaysia and Indonesia where I visited several Sama Dilaut communities. I talked to them about their daily lives, followed fishing and continued to learn the basics of two of their dialects, Central Sinama and Indonesian Bajo.
Noah – one of the last young boys who make a living from spearfishing in Davao
The trip started in Matina Aplaya in the outskirts of the metropolis Davao City in southern Philippines. Fish is on the decline and most people in the village make a living from vending of pearls, second hand clothes and shoes. However, a few families still make a living from the sea, and they are incredible divers.
I have been visiting Matina Aplaya every year since 2010 and I have always been accompanied by Issau and his son Noah. Noah is one of the few boys in the village who has grown up becoming a skin diver along with his father. On daily fishing expeditions, they spear fish and collect sea urchins, sea shells and clams in the coral reefs surrounding the town. It is fascinating to see that Noah has grown up to become a skilled fisherman who contributes to the household with his spear gun.
Zamboanga – Sama Dilaut resettlement after the 2013 fire
In 2013, the outskirts of Zamboanga were struck by a fire that destroyed thousands of houses and displaced thousands of Sama Dilaut and Tausug people. For months, they were living in a temporary camp in a sport arena close to the town centre.
After my visit in Davao, I made a two-day stopover in Zamboanga in western Mindanao before travelling to Tawi-Tawi. I visited some newly constructed villages set up by NGO:s and local authorities exclusively for the Sama, and many of the houses have been built in a traditional way. However, the daily life of many Sama Dilaut in Zamboanga is tough and it is getting harder and harder to make a living from the ocean. Many people are begging in the harbour. Yet others have fled to other cities in the Philippines.
Sitangkai – traditional dance in the Venice of the south
Despite recent kidnapping incidents in the Sulu I decided to travel to Tawi-Tawi in southwestern Philippines. I visited the Sama Study Center and the Marine museum in Tawi-Tawi where I met Rasul M. Sabal, the museum director. He has a keen interest in Sama Dilaut culture and show sincere concern with their challenges.
While in Tawi-Tawi I took the opportunity to pay a visit to Sitangkai along with Rasul M. Sabal and two policemen. Over the last years, very few foreigners have been in the area and I was fortunate to be able to visit the legendary community where thousands of people live in what is called the “Venice of the south” next to a tiny piece of land.
In Sitangkai, Sama elders performed religious dance that is normally performed during the magpai baha’u ceremony, an annual ritual taking place once a year in community (this year it will be held in May and it attracts Sama people from all over Sulu and Sabah). It was great to experience their hospitality and kindness!
I came to know that the interaction between Sabah and southern Philippines is intense despite stricter migration policies on the Malaysian side, and boats are heading between the locations more or less every night. In Sitangkai, I also saw how octopuses were shipped on a large scale to Tawi-Tawi and further to Zamboanga and Manila. However, the production of sea weeds has dropped due to reduced market prices.
After Tawi-Tawi, the initial plan was to take a ferry to Semporna, but the ferry company had lost its license so I took another ferry going back to Zamboanga instead. In the harbour of Bongao, more than 20 Sama Dilaut children were diving for coins, displaying great skills.
On the trip back to Zamboanga, I met two Sama brothers from Tawi-Tawi who were on their way to Palawan to join a fishing crew going deep in the South China Sea. They told me that they usually made use of explosives and compressors during these trips, and that the expeditions used to last for about one month. I asked them about their eardrums, and they said that they had broken them. Then, I asked them about their hearing ability, and they told me that their hearing was okay but that they had problems localising sounds. The brothers’ story is interesting since it has been unclear whether Sama fishermen break their eardrums or not. I would say that most the Sama Dilaut divers permanently rupture their eardrums, either on purpose or accidentally, and they take medicine in the case of infection. However, some fishermen do also equalize their ears and some may have hands free techniques for doing so.
When the ferry arrived in Zamboanga day after, the scene changed. Nearly 100 Sama begged for money in the harbour, including elders, and the atmosphere was more tense than in Bongao. It got obvious that life is very difficult in Zamboanga, and it is not surprising that so many Sama Dilaut are now roaming the cities of Manila, Cebu and other Philippine cities.
Meeting with Sulbin on Mabul
After the trip to Sulu, I made a short stop in Semporna where I went to Mabul to meet the Sama community there. I was lucky to meet Sulbin – the diver who walks on the sea floor for nearly two minutes in a widespread BBC production. He told me that he had just come back from seasonal work in Kota Kinabalu. Hence, also the most skilled fishermen might choose to make a living in the job market rather than make their own fishing trips in the region!
However, in Semporna many Sama Dilaut still live in houseboats and they roam the many islands in search of fish, sea shells, clams, sea urchins and so on. Many of the more traditional Sama have no option but to continue extracting resources from the ocean.
Sama Dilaut spear-gun fishing women Wakatobi
After the short stop in Malaysia, I went on to Makassar in Indonesia where I met up with Professor Erika Schagatay from Mid-Sweden University, for our third trip together. We headed towards the island of Buton in southern Sulawesi where we spent a few days in the village of Topa (the sama village where Erika Schagatay first came in contact with Sama people in 1988). In the village, we followed fishing, talked to the people and made physiological research on Sama divers. For example, we measured the diver’s lung capacity, spleen size and feet size.
After the stay in Topa, we took a ferry to Wangi-Wangi in the Wakatobi island group. We spent one day in Wangi-Wangi before we visited the village of Samepla further out in the archipelago, where we spent four days. Sampela is located more than one hundred meters from the island of Kaledupa and have got attention in several film projects throughout the years, in for example BBC:s series “Hunters of the South Seas” and the movie “The Mirror Never Lies”. During our stay in the village, we joined a group of women spearfishing, and it was fascinating to see their acquaintance with the ocean. We also followed fishing with Tadi, a 70-year-old fisherman who is still an incredible fisherman. He was the most successful fisherman during our trips, outperforming much younger spear gun fishermen. We also got the opportunity to measure Tadi’s spleen, and it turned out that his spleen is much bigger than peoples at the same age and with the same body size, and whom do not make a living from diving. The spleen is a very critical organ for experienced divers, since it consists of a high concentration of blood cells that can be released under pressure.
Also in Sampela, life is getting more and more difficult because of decline in fish. In the community, there is also a problem of indebtedness and large interest rates. Hence, many Sama fishermen are forced to increase fishing efforts despite recent decline in marine resources. Or in other words, they live on resources yet to be extracted.
Sampela is located within the Wakatobi National Park, but nevertheless, too little is done to prevent over-exploitation of the area. Big fishing boats enter the waters even though only small scale fishing methods are allowed. Hence, more must be done to reinforce the park regulations and to protect the area and the people living there.
Kabalutan – a pregnant woman showing great diving skills
My last visit in Indonesia took place in the community of Kabalutan in the Gulf of Tomini, central Sulawesi. Also this community is known from a few TV productions. Here, BBC produced a short documentary about Sama Dilaut with Tanya Streeter in 2007, in which young Sama children dive 12 meters repeatedly displaying great skills. This is also the place where Svea Andersson’s depicts a eight month pregnant woman diving for shell fish in the movie “Sulawesi, the last sea nomads”.
Along with two Sama families, I followed on a pongka fishing trip – a fishing trip at sea lasting for a few days. We stayed two nights at sea, collecting shell fish and spear-gunned fish. Among those who followed were 17 year old Muspang, the youngest boy in BBC:s movie with Tanya Streeter He is already a father and a great diver. However, I was more impressed by his mother, the same woman that was highlighted in Svea Andersson’s movie. Again pregnant, she was diving up to eight meters in search for shell fish and clams, as well as spear gun fishing. She is one of the last free diving Sama women with great diving abilities; one of the few remaining in not only Kabalutan but most likely in most Sama communities throughout Southeast Asia.
However, the amount of large commercial fish in on the decline also in Kabalutan, and it will be difficult for Sama people to sustain a living at the sea. Shell fish and octopus are still in quite big numbers since they mostly are being extracted using traditional fishing methods including diving, but other fish are rare. Who knows what life will look like after just 10 years when the consequences of coral bleaching and rising ocean temperatures will be much more severe than today?
The first Sama Dilaut International Conference will be held December 1-3 in Tawi-Tawi, Philippines. Among the invited scholars are Prof. Harry Arlo Nimmo, who made extensive fieldworks among Sama Dilaut in Tawi-Tawi in the 60’s. He has written the book Magosaha: An Ethnography of the Tawi-Tawi Sama Dilau and the memoir The Songs of Salanda and Other Stories of Sulu.
The conference is organized by Sama Studies Center and aims to open a dialouge between scholars, scientists, statesmen and development actors with the Sama Dilaut themselves. The meeting will be “an opportunity to look back to what has always been held by the Sama Dilaut as their life-ways since time immemorial and as traditional, and to commit to give them renewed winds to sail and to secure abundant seas that may facilitate their journey to reclaim their space and reorder their present realities”.
Objectives of the conference:
- To strengthen research and encourage academic interest on the plight and situation of the Sama Dilaut (Badjao) by highlighting their roles in the social and cultural development of the Sama society, and their contributions to the dynamics of maritime and sea-based economy in Tawi-Tawi and the Philippine waters, and the impact and consequences of geopolitics in Southeast Asian region in this roles and contributions;
- To discuss development models and survey affirmative actions, and evaluate empowerment programs and interventions for this most marginalized of Sama ethnic communities; and
- To provide venue and spaces for the Sama Dilaut to tell their narratives and as well as for listening to alternative voices speaking as interlocutors for Sama Dilaut issues.
More information about the conference can be found here: Sama Dilaut International Conference
At year-end, I and photographer Andreas Ragnatsson went to the Philippines and Malaysia to meet Sama Dilaut. In Davao, the Philippines, we spearfished with superb divers. In Semporna, Malaysia, we visited the islands of Bodgaya, Mabul, Sibuan and Maiga and talked to them who are still living on their “lepa” houseboats.
Different groups of Sama Dilaut
Sama Dilaut in Philippines, Malaysia and Indonesia can be divided into four groups, of which today only two are living on boats. The northernmost group is Sama Dilaut from Zamboanga, Basilan and Jolo, who are generally known as “Badjao” in the Philippines . They live today scattered over large parts of the Philippines, (eg, Davao, Manila, Cebu) where they fled after unrest in the Sulu Sea. None of them live on house boats today, but many still make a living from fishing and live along the shorelines.
The largest group of boat nomads is Sama Dilaut from Bongao, Tawi-Tawi, Philippines . Most of these, however, have fled to Sabah, Malaysia, where many still live on their house boats. Today, there are no nomads left in Tawi-Tawi because of the unsecure situation in the region. Many Sama Dilaut house-dwellers in Semporna told me that they want to return to their boat-dwelling lifestyle, which make them more mobile and give them better fishing opportunities. For many it is only a matter of money – if they would afford it they would build a houseboat and return to the sea.
A closely related group to Sama Dilaut of Tawi-Tawi is Sama Dilaut of Sitankai, Philippines, that used to live on the sea. Many of these people came to Semporna in the 60’s on their houseboats where they established the village Bangaw Bangaw. Today all of them live in houses
The fourth group is Sama Dilaut of Indonesia, who generally are called Indonesian Bajau. They speak a slightly different dialect than their relatives in the Sulu Sea but most words that are related to the sea are identical, as for example “amessi” (hook-and-line fishing), “amana” (speargun fishing) and “amosaj” (to paddle). Indonesian Bajau live over large parts of Sulawesi and even as far south as Flores. Today, only few Indonesian Bajau live on house boats and the number decreaces. Only ten years ago many Indonesian Bajau were boat-dwellers along the eastern coast of Sulawesi (eg, Lasolo) but today there are only few nomads in the Togian Gulf left.
Bajau Laut have been living in Southeast Sulawesi since the 16th century. Originally, they were involved in the spice trade, transporting lucrative spices from Moluccas to Borneo. When the Dutch colonialists changed the trade routes many Bajau Laut stayed on their houseboats made a living completely from sea harvesting. Some do still today.
WWF in Wakatobi
In one of the villages of Buton, Lasalimu, I met Sadar, a Bajau who works for WWF in Wakatobi. His work is to persuade Bajau fishermen stop dynamite fishing. “In Wakatobi we have been quite successful but further north many Bajau use fish bombs and cyanide”.
In Wakatobi most fishermen make a living from skin diving, as compressors are illegal. “We also try to regulate how much fish they can catch a day”, Sadar told me, “it is necessary because they are fishing in Wakatobi National Park”.
Sadar also told me that it still is practice among some Bajau to throw the placenta in the ocean after giving birth. They believe that the child will protect the sea as “it is the home of their sibling”. You can read more in this article in Al Jazeera: Indonesia’s last nomadic sea gypsies (2012-10-06).
Born on the sea
After my visit in Buton I headed north to Lasolo where many Bajau Laut are living on small, isolated islands. Around these islands, many Bajau used to live on the boats till only a few years ago. More or less everyone above 10 years old were born on the sea.
The author of Outcasts of the Islands, Sebastian Hope, visited Lasolo in the last decade and met sea nomads close to Boenaga and island of Labengke in Lasolo. But today all of them are living in houses.
In the Gulf of Togian in northern Sulawesi, however, it is still possible to find Bajau Laut who have been on the boat their entire lives.
Sama Language – spread over the Coral Triangle
Throughout The Coral Triangle you can find pockets of Sama communities, distinctive from the surrounding society, but speaking more or less the same language as other Sama groups living miles away.
It has been very interesting to be able to meet Sama people in Philippines, Malaysia and Indonesia and compare their dialects. As a matter of fact, there are still many similarities in their languages. For example, most words related to their maritime lifestyle are identical in all dialects I have encountered, like “amana” (spear-gun fishing) “messi” (hook-and-line fishing), “anga ringi” (netfishing), “e‘bong” (dolphin), “kalitan” (shark), “bokko´” (turtle), “gojak” (waves), “mosaj” (to paddle).
During my next Indonesian trip I would like to visit Flores, not far from Australia … probably they will speak a similar dialect here as well… But that will be explored during another journey. Now I am heading back to Semporna.
In Eastern Kalimantan, Borneo, Bajau Laut have been living for generations. Originally they arrived on houseboats from the Sulu Sea.
I visited Derawan Islands where I stayed for one week. It is a tourist paradise with excellent diving spots and fascinating sea creatures as manta rays and hawksbill sea turtles. Most people on the islands are Bajau and they speak more or less the same dialect as in Semporna, Malaysia. I was pleased to see that most children still speak Sinama – and they were spending their afternoons swimming and playing next to sea turtles in the shallow waters.
Derawan Islands consist of a large number of island, of whom two are inhabited – Pulau Derawan and Pulau Maratua. The islands are far from as exploited as for example Mabul in Semporna, and all resorts are owned and run by local people.
One of the islands, Sanalaki, is well-known for their hawksbill turtles and coral manta ray . Here visitors can swim with the giant rays and watch the turtles when they enter the beach at night laying their eggs. On the island of Kakaban you can also find a lake full of jellyfish – but they are completely harmless.
Recently, many Sama Dilaut used to stay in the area, moving between Indonesia, Philippines and Malaysia in search for fishing grounds. But today there are no nomads left, as the Indonesian government repeatedly have confiscated their boats and sent them back to Malaysia. They are not welcome as they lack legal papers.
The local people control the islands – they where empty when Bajau settled here for more than 100 years ago. “I want Sanalaki to become as Sipadan in Malaysia”, one local Bajau dive operator told me, “a tourist heaven and a sanctuary”.
The Derawan Islands are also important for the Indonesian live fish trade. From here, great numbers of lobster and groupers are transported to Surabaya on Java and Tawau in Sabah, Malaysia. Much of the fish end up on luxury restaurants in Jakarta, Singapore, Kuala Lumpur and Hong Kong.
After Derawan I am heading towards Southeast Sulawesi where I will visit Bajo Laut, who have lived in the area for hundreds of years. They are distant relatives to Bajau Laut in the Sulu Sea, but much of their lifestyle are the same. Once again I will visit the village Topa which I went to almost two years ago – following the footsteps of Erika Schagatay, who was there for more than 20 years ago.
It is always a pleasant experience to come to the Sama Community in Matina Aplaya, Davao City, Philippines. Almost 100 people greeted me when I entered the village in the beginning of December. I could see children playing drums, fishermen preparing their “pana” (speargun) and women nursing their small children.
Then followed one month of swimming, fishing, playing with children, playing volleyball and celebrating Christmas and New Year.
Skilled 10-year old fisherman
I had the opportunity to follow one of the younger fishermen in the village, Jimmy, 10,at sea. I followed him underwater while he caught fish after fish with his harpoon. He is one of few children in the village that has grew up as a traditional fisherman, and hence, one of few children that has ruptured his eardrum. However, it is getting more and more difficult to make a living from the sea, due to over-fishing and more extreme weather.
But why do they rupture their eardrums? In fact, it is seen as practical since diving is an everyday activity. The ruptured eardrum can be seen as an investment: If you are going to make more than 10 000 dives during your lifetime, and if you never have learned how to equalize properly, then rupturing your eardrum becomes a shortcut to the ocean’s depth. “If you rupture it once, you will have no problem diving throughout your life” one young fisherman explained. Of course, older men have hearing problems and the fishermen will get ear infections over the years as water enters their middle ears … but they are taking inherited medicines … and the inner ear will generally never be affected.
In the Sama community of Matina Aplaya it is still common that the fishermen make up to three week long journeys to abundant fishing spots further south in the Davao Gulf. It is not easy – but not either impossible – to make a living completely from the sea. They sleep on the boat: spearfish during the day and hook-and-line fish in the evening. When they return to the village they normally buy a big fish and share it with their families… Many of the fishermen continue to harvest at sea – no matter what the season or happenings around them.
How big is their ecological footprint?
This is the fourth time I visit the village since 2010 when I started to study about Bajau Laut right here – and I hope to be able to make many future visits. One new thing for this time was that a quite many families had started to make a living from selling of secondhand shoes, that they buy in the market in sacks for either 1 000 pesos or 2 800 pesos each. Then, they are repairing the shoes and selling them to people in Davao and neighboring cities.
In December it is also common that Sama and other local tribes of Davao are playing music and dance while going from house to house begging for food and money. The Sama children are performing with recycled drums, made by metal and plastic waste. A group of enthusiastic children can make 200-300 pesos a day in this way.
Many people might say that Sama are uncivilized and dirty – that they are begging parasites. But in fact they are making a lot of recycling services that the modern Philippine society doesn’t do. For example they collect a lot metal and plastic waste from the shorelines, they reuse and restore clothes and shoes, establish a flourishing second hand market, and they catch fish with sustaining fishing methods. Most of their money goes to purchasing of water and food, like cassava, fish and fruits – even if they also are buying Christmas gifts. Overall, their ecological footprint is nearly zero.
Recently, the Philippine spokesperson at United Nations climate change conference in Doha, Naderev Sano, made a long-lasting impression on many of the listeners. Only days before the eastern Mindanao of Philippines had been hit by a devastating typhoon… ”There is massive and widespread devastation back home. Heartbreaking tragedies like this are not unique to the Philippines”, he said, emphasizing that Philippines and other countries may face more extreme weather disturbances if climate change is left unchecked You can see his speech here: Plea by Naderev M. Sano of the Phillipines and read an article in the Guardian about the speech here: Will Philippines negotiator’s tears change our course on climate change?
Indeed, the Philippines and the world are facing many climate-related challenges – and I am sure that we can learn a lot from the Bajau tackling these problems!
Badjao Association of Matina Aplaya
Another new thing in the community is that they have organized themselves in an organization – The Badjao Associaition of Matina Aplaya. The purpose of the organization is to establish a long-term livelihood for the community, either on fishing or selling of clothes and pearls. For example, the members of the organization will be able to borrow money for a small cost. They are also planning to build a local school: “If the children can learn how to read and write in their own language, they will be able to attend the regular Philippine school”, Lolita, one of the community leaders, said.
In the beginning of January I am heading back to Malaysia – and from there I will go to Sulawesi, Indonesia, where I will live with the Bajo, another Sama Dilaut group, who have been separated from their relatives in Malaysia and Philippines for almost 200 years. In Sulawesi I will visit the isolated village Lasolo – one of the places where their might still be boat-dwelling Sama people outside of Borneo.
For more than one month I have been living in Semporna, in Sabah, where I have visited remote islands and several Sama Dilaut (Bajau Laut) communities. I have talked to sea nomads, been diving, attained a wedding and continued to learn the basics of Sinama.
One thing that surprises me is the life pulse and energy I always feel when I visit a Sama community. Even if I go to Semporna or remote parts of Mindanao I always get the same feeling.
Hundreds of sea nomads
In Semporna hundreds of house boats have their moorage, either close to one of the many islands in the region or simply in Semporna town close to the Sama Dilaut communities Kampong Halo and Bangau Bangau. They make their living entirely from the sea: they are net fishing, hook-fishing, spear gun fishing and dive for sea cucumber and pearls. During low tide they also go along the shallow corals and collect sea shells. It is fascinating to see the water adaptation of the Sama – an adaptation that starts in early age. A child learns to swim when it is 2-3 years old, it learns how to paddle a boat at five and dive at the age of six.
Unfortunately, some of the Sama Dilaut fishermen are also involved in dynamite fishing and compressor diving. Fish bombing is, of course, devastating for the marine life as it completely destroys the corals. But as one fisherman told me: “when I go hook fishing I must wait a long time for a catch, but if I throw a bomb I will get plenty of fish in seconds!” Of course, bomb fishing is highly illegal and leads to imprison and big fines. I met one pregnant woman with small children whose husband and oldest son had been caught bombing fish, which left the family without livelihood.
It is important to note, however, that it is unusual that boat living Sama make a living from dynamite fishing. It is much more common among more settled, house-dwelling Sama Dilaut fishermen.
Refugees from Philippines
Nearly all Sama Dilaut in Sabah are refugees from the Philippines. Many of them lack Identity cards and passports. A majority doesn’t even have a birth certificate. Without ID you have no right to get medical support (it costs 50 RM, approximately 17 USD without ID for a medical checkup and only 1 RM if you are a Malaysian citizen) and schooling. However, many Sama Dilaut have a “lepa passport” (a houseboat passport) authorized by the local government which gives them right to stay in the waters of Sabah.
Probably, the reason behind Sama Dilaut’s partly devastating fishing methods is linked to the fact that they are not recognized as legal – as a matter of fact many Sama Dilaut do never set their foot on land because of fear of deportation. Hence, if you are living there illegally and don’t get any support from local authorities, you might be tempted to get involved in devastating fishing practices.
When I talk to the Sama Dilaut they all tell me one thing – they are afraid of the Tausug people of the Sulu – which have ruled the area for centuries. Today many Tausug are armed and some of them have been in part of the creation of the Abu Sayyaf guerilla. For decades they have been fighting against the Philippine government in order to establish a free Muslim state in southern Philippines. Recently, a peace agreement were settled which has calmed the overall situation, but single Sama individuals are still under huge threat (see: Philippines peace deal is far from a done deal for more information). Their catch and their machines are taken under night. Young women are forced to marry which make them escape in the middle of the night. Bombs have been thrown into their houseboats.
In Philippines, the police don’t do much to ease the situation for Sama Dilaut. In Malaysia, however, the police and military are very active, and thousands of tourists are arriving every year, which make the situation calm.
Have they always been nomads?
It is estimated that the nomadic lifestyle of Sama Dilaut is more than 1000 years old, but I have wondered if the present day sea nomads always have been living in the boat, or if they till recently have been living in houses? During my first month of stay with Sama Dilaut I have been asking many nomads about their history. As a matter of fact, some of the present day sea nomads have actually quite recently been living in houses in Philippines, but they resurrected their forefathers way of living when they came as refugees to Malaysia. It is still unclear how many of the nomads that have been nomads for generations, and that is one question I would like to figure out during my six month long stay in Southeast Asia.
In one week I am going to Philippines where I will visit the Sama Dilaut community in Matina Aplaya, Davao City. Here many people are living entirely on spear-gun fishing and they use no compressors and no dynamite. I am really looking forward to come back to Mindanao!
On October 18th, I am heading towards Southeast Asia for a six months long stay with Bajau Laut – The People of the Sea.
My first stop will be on Borneo, Malaysia, where I will live among Bajau Laut sea nomads. Still, more than hundeds of people spend their entire lives on boats. Here I will gather material for my Master Thesis on dynamite fishing and make a short movie about Bajau Laut’s maritime lifestyle. Thanks to Barnens Stipendiefond that has given me a grant for making the film!
During the journey I will also spend time in southern Philippines, where I will visit a Bajau Laut community in Davao City – where I have lived for several months.
In the beginning of next year I am also heading towards Sulawesi, Indonesia, where I will live among Bajo people (they are relatives of Bajau in Malaysia and Philippines, but speak a different dialect).
Throughout the journey I will also collect diving statistics for professor Erika Schagatay at the Mid-Sweden University. I am bringing three logging devices that will measure how deep the Bajau fishermen dive and for how long they stay under water. The most interesting data is, though, their underwater working time during a longer period of diving.
I will make continuous updates on the blog during the journey.
