In august I visited Maratua for some measurements on the seagrass there. When I arrived the water was too high to work; time for some exploring! So I asked a man from the village about the marine lakes there. Off we went, through palm forests and mangroves with a “parang” cutting out our way. And …

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.

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. …

The 21th of May my supervisors and students are arriving so I …
Transport of research materials Balikpapan-Derawan
Trying to find all the materials needed for research is one thing. Transporting them to Derawan is really much more adventurous. The rainy season is not over yet and the road between Samarinda and Berau is in bad condition and sometimes not excisting anymore. But this is the only way to get your stuff (if …

Collecting materials for experiment 1
Before I can start with experiment 1, I have to start from scratch with the collection of the materials which are needed to start experiment 1. The family of the homestay in Balikpapan are pro-actively helping me with every weird thing that I carry to their house. After showering I exitedly noticed that the father …
