Closing one chapter and opening another

It is time to share some very big news. My time in Australia has officially come to an end and I am starting a new and exciting chapter on the other side of the world. From April onward I will officially become a “Research Fellow in Quantitative Tropical Marine Ecology” at the University of Leeds in the UK. In other words, for the next two years I will work as a postdoctoral researcher on a very exciting new project.

I will write about the new project in more detail soon, but right now I am feeling a bit nostalgic about the past 6 years of living and becoming a scientist in Australia .

Celebrating the end of an experiment on the Great Barrier Reef

I arrived in Australia as a dive instructor, thinking I’d be there for a few months to help out a good friend with a research project on cleaner wrasses in the Great Barrier Reef. Working and living on Lizard Island Research Station gave me the chance to meet some amazing marine scientists passionate about their research. More than anything else, the people I met there are what pushed me in the direction of becoming a marine scientist.

A series of fortunate events lead me to Perth and I somehow managed to convince Professor Euan Harvey that taking on a semi-nomadic beach bum for a student would be a great idea. To this day I still do not know if  Euan was being very wise or very stupid, but once I got my foot in the door of the Fish Ecology Lab it took them about 6 years to get me out again.

While I never planned on spending a long time in Australia, it didn’t take me long to appreciate the beauty of the place. Western Australia in particular is basically a Europe-sized playground for people who love the outdoors. I can’t count how many camping trips, dives, surf sessions, ocean swims, hikes, … I’ve done in recent years and I still haven’t seen half of what I’d want to see. Some of the highlights that come to mind include camping on remote beaches, diving with seadragons, snorkeling with sea lions, and sunrise surf sessions with friends. I won’t even begin to write about the many wine tasting sessions down south 🙂

I was lucky enough to meet some amazing people along my journey. Almost without noticing it, I built up a group of colleagues and friends. I love the typical Australian easy-going, honest (sometimes in-your-face) style of communication. Even if it could not be more different from what I was used to in Indonesia (or even Belgium). The people more than anything is what make or break a place, and I will miss the ones I left behind in Perth dearly.

When I arrived in Australia I never expected that it would become a second home, but that is exactly what happened. The people, the wildlife, the landscapes, all of it have found a spot in my heart, and I am grateful for my time there. I am very much looking forward to starting a new chapter, if it’s even half as good as the last one it is going to be fantastic.

Marine biodiversity in Oman: Mini-blog 3 – Workshop time

The Oman fish biodiversity trip I am currently doing is nearly over. We spent the last days in a workshop at the Sultan Qaboos University in Muscat. The workshop focus was on “Bridging the gap between marine resource managers and research institutions in Oman and Australia”. Besides our team, the workshop was attended by Omani researchers and government officials, international researchers working in the region, and even by marine students from the university.

With such a varied group of attending researchers and presenters, talks were bound to be interesting and go beyond the work I am familiar with. The first day focused on seas around Oman, its diversity and natural history. Since this was my first visit to Oman and I know very little about its marine life, there was a lot of interesting new information to absorb.

The Omani seas are fascinating for many reasons, but one of the things that really stuck with me was how big the environmental differences are in a relatively small area. The north of Oman has seas that get very hot, with a high salinity and a very different fauna and flora than the southern areas. The south of Oman has coral reefs, but also has a strong cold upwelling each summer. This upwelling is so strong that temporary kelp forests grow here in summer! I did not get to dive there this trip and the kelp has already disappeared this time of the year, but it would be fascinating to come back and dive in the Salalah area.

Hussein Al Masroori talks about designing solutions to reduce ghost fishing by lost fish traps

The second day of the workshop moved from natural history to new monitoring techniques, and explored some of the regions nearby Oman. There was a thought-provoking (but sad) talk about the heavy impact of coral bleaching in the Arabian Gulf. Water temperatures in the summer of 2017 reached up to 36°C, and some areas lost more than 90% of coral cover! Our team members also presented some of their personal work, Joey talked about eDNA, Darren about monitoring biodiversity in the Red Sea, and Chris talked about how cryptobenthic fishes could be used a sensitive measure of changes in reef health.

In an interesting discussion afterwards, it became very clear that collaborating across different countries is more effective than just working as a loner. When experts in certain fields can share their work and skills with researchers that may not have the infrastructure or cannot get the training in the country they work, everyone benefits. Local researchers often have a very extensive knowledge and valuable insights that visiting researchers just don’t have. As visitors, we can offer a new perspective and stimulate new ideas to help push the boundaries of knowledge.

People like Joey and Alyssa, who stimulate these kind of collaborations, are the ones that (in my humble opinion) will make the biggest difference to marine science. Not just to improve our understanding of the ocean, but also to improve how we can sustainable use the ocean, or protect the areas and species that need it most.

Marine biodiversity in Oman: Mini-blog 1

Great news, I am on the road again for a new fieldwork adventure! Three days ago I left Perth to join a great team of researchers for a week of marine science action in Oman. I will try to post a few updates as we go along, much in the same way as during my last fieldwork trip.

On our way to the Musandam reefs

The trip is organised Dr. Joey DiBattista and Dr. Alyssa Marshell, as a collaboration between the Australian Museum and the Department of Marine Sciences and Fisheries at Sultan Qaboos University in Oman. Joey and Alyssa received funding from the council for Australian-Arab Relations (CAAR) to study the fish biodiversity in Oman and to develop methods to monitor that fish diversity more efficiently. Ultimately, the goal of our work here is to support the management of marine resources in the region.

Most of the trip consists of diving in different places across the country. I am writing this blog in Musandam, a stunningly beautiful area in the north of the country. We are surveying fish, collecting fish and water samples for genetic research, and testing new methods to collect environmental DNA. We will be working here a few more days before flying back to Muscat.

The last leg of our trip is dedicated to a workshop in the Sultan Qaboos University During the workshop, local and Australian scientists will give presentations on their work, and most of us will also present some of our own work that might be of interest to researchers in the region. I’m very much looking forward to the discussions and ideas that will come out of this workshop, they’re one of the more exciting aspects of these kind of research trips!

Well, that and the diving and exploring parts of course 😉

Keep an eye on the blog in the coming days, I’ll post a few updates as we go along!

 

Time for something new

I never liked going to school. Not as a kid, not as a teenager, and not even as a young adult. Maybe I just disliked being bored so often? Even in the classes I was interested in, I felt that just absorbing all the knowledge in world was not exciting. My impression was that science already knew everything and that new discoveries were pretty much impossible. That science had somehow “stopped”.

Well, let me tell you one thing, it most definitely has not! I was not learning “all the knowledge in the world”, in fact LOTS of new things are discovered all the time! Since this blog is about ocean critters, let’s look at some of the critters that have recently been discovered. In the last year alone, new seahorses, frogfishes, gobies, jawfishes, and many other species have been discovered. So if you thought you’d seen it all, think again 😉

Seahorses and relatives

A new species of pygmy seahorse was described 3 months ago by Graham Short and colleagues. This ridiculously cute little seahorse lives in Japan and is called Hippocampus japapigu (=Japanese pig seahorse). These little wonders are less than 2cm in size and have a wonderful honeycomb colour pattern. Unlike some other pygmy seahorses, the Japanese pygmy seahorse does not live in seafans, instead it can be found in hydroids, algae, or soft corals.

Even more recently, less than a month ago, another new pygmy seahorse species was discovered in South Africa. The first ever pygmy seahorse in South Africa! Dive operators in the Sodwana Bay region had found this small seahorse and asked pygmy seahorse expert Richard Smith about it. Together with IUCN seahorse expert Louw Claassens he went for an expedition and has confirmed the new species. It has not got a name just yet, but should be officially described sometime next year.

During the same expedition, Richard and Louw also found a new species of pygmy pipehorse! You might have never heard of pipehorses, but they are just fantastic. Sort of like a seahorse that disguised itself as a pipefish, or maybe the other way around?

Frogfish

Big news from Australia as well! A new frogfish species was described in the journal Copeia this week. The Narungga frogfish (Histiophryne narungga) is found in South and West Australia, and was named after the indigenous people living in the area. The beautiful new frogfish lives mostly in shallow water, where it does what frogfishes does best: mimicking sponges or other benthic organisms, hoping to catch unsuspecting prey that swims by. This small (less than 10cm), new frogfish is very much on my “critters to see before I leave Australia”-wish list!

The researchers describing the Narungga frogfish, Rachel Arnold and Theodore Pietsch, are pretty much the rock stars of the frogfish world. Together they have described 9 new frogfish species in the last 10 years, the most famous of which is the Psychedelic frogfish!

Gobies

I’ll be honest, for someone who studies cryptobenthic fishes, I don’t know nearly enough about gobies. Luckily, other researcher do know a lot about gobies and they seem to be good at finding new species as well. This year a new species was discovered from the west Pacific Ocean. The polkadot dwarf goby (Eviota maculosa) lives in Indonesia, Australia and Pohnpei. Its small size, less than 2cm, probably explains why it has taken researchers so long to realise this was an undescribed species.

Jawfishes

If you are not a keen muck diver or underwater photographer, you can be forgiven for not knowing about jawfishes. These cryptic fish live in holes in the sand and don’t venture out very often. Most notably, they are “mouthbrooders“, fish that hatch their eggs in their mouths. This week, two new jawfishes were described from Brazil. Thiony’s jawfish (Opistognathus thionyi) and the Brazilian dusky jawfish (Opistognathus vicinus) both seem to be endemic to Brazil, meaning they do not occur anywhere else. Thiony’s jawfish seems to live deeper than the Brazilian dusky jawfish, but otherwise, not much else is known about these new species.

This list of new critters is by no means complete. Many more species have been recently discovered, and many more will be discovered in the future. I find it very exciting that science isn’t ready yet and that there is so much more of the amazing natural world left to discover. If that doesn’t make you want to become a scientist, I don’t know what will… (We often have cookies in the office if that’s more your thing?)
