During the last three months, I have been lucky enough to be based in Lembeh Strait in Indonesia. While most of my time there was spent writing, I also managed to get a fair few dives in so I wouldn’t forget why I started this PhD-project in the first place. What motivated me to go back to university after 7 years of working across the world, was curiosity about the marine life I love so much.
While working as a dive instructor, I would constantly wonder about what I saw. Why did certain animals only appear in some spots or at certain times of the year? How long do frogfish/pygmy seahorses/other-fish-of-choice live? Do camouflaged fish choose a place to live depending on their own colour, or do they change their colour depending on where they live? What eats nudibranchs? What do nudibranchs eat? …? A few guide books offered answers to some of my questions, but most remained unanswered. Over the years, it slowly became clear that the answers were not locked up in some dusty university-dungeon or inside an even dustier professor’s brain. The truth is, science didn’t know the answers to many of the questions I had.
Many divers would be astonished by how little we really know about the ocean. As anyone who has heard me talk about my research will tell you, I answer a lot of questions with “I don’t know”. Even many of the most basic questions still haven’t been answered. There is a lot of great research going on, but there is even more ocean out there to be studied. When it started to dawn on me that hardly anyone was trying to find the answers to my questions, I decided to try to find them myself.
Of course it wasn’t as quick and straightforward as I write it here. But in the end (mostly through stubbornness and dumb luck) I managed to get myself into a project where I could spend multiple years trying to find out some answers myself. Turns out finding answers isn’t as easy as you’d think! But it also turns out that it is an even better way to spend one’s time than traipsing across the world as a dive instructor. The result is that after 3 years I have answered a fraction of my initial questions, while simultaneously tripling (quadrupling? quintupling?) the number of questions I had in the start!
What I am planning to do with those new questions is a matter for another post, but this final field trip definitely motivated me to keep searching for answers…
