After 1 week of preparation the penyu team arrived at Derawan. Here Ibu Heldi invested my last payments in improving her place. Now it feels even more like home and our own research station even! In the week that my supervisors are here we revisited the seagrass meadows that they sampled in 2003. Sampling the …

Fieldwork with Wawan Derawan 2009

About infections and Stingrays
And now a horror story about infections and dangerous animals, which combination was still lacking on this blog. Halfway my experiments I got stung by a stingray when I walked to the experimental site (knee-deep water). I felt something very sharp and hard stinging 5 cm into my feet, 3 cm under my ankle, resulting …

I am working together with Wawan Kiswara (the Indonesian seagrass expert from Jakarta) who is very helpful and has a never-ending hospitality surge. Together with his daughter Nina we …

NH4 toxicity experiment
After performing the same experiment with transported Thalassia hemprichii last year I wanted to test the same treatments in the field. So after some creative thinking I came up with this set-up (click for more pics): I’m (amongs others) testing if high ammonia concentrations could cause troubles to seagrass.
More Fieldwork at Derawan
Time is flying. The enclosure experiment is finished and Laura and Madelon left for their holidays. Time for me to visit the civilized world and put some pictures on the internet. It isn’t very structured but that is because only emailing this pictures costed me 1 1/2 a small discription can be found next to …
Turtles @ Derawan
In the first week at Derawan I saw so many turtles, therefore a post about the “production of new turtles”. Yesterday night I saw 4 turtles (Chelonia mydas) crawling on the beach to search for a suitable site to lay their eggs above the high tide line. She digged out a large hole in the …
My first cage
Before my supervisors arrive and the experiment will be started I’m first testing my cage set-up. The cages are build out of concrete-iron with fishing nets on the sides and on top of the cage, attached by cable ties. The net is 5cm in diameter to prevent the turtles from getting stuck into the net. …
