Seagrass Systems Under Nutrient Loads and Grazing

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 same sites from the river to the open see we saw a lot of variation in species composition, algea cover, morphology. At the moment that I write this article Leon Lamers is travelling back to Nijmegen with +/- 10kg of dried seagras, sea water, and syringes with gas. Sjoerd will analyse the samples when he is back in february, we are looking forward to the results of the plant-nutrient analysis.

Check the photos to get an impression! And leave a comment, so that we also get some information back

We can also receive old fashioned post. Here is the adress:

The PENYU-logo in detail:

This Autumn our seagrass researchers team from Radboud university Nijmegen and NIOO Yerseke visited our seagrass collegues in the Wadden Sea Station Sylt Germany. Besides the presentations we had some wonderfull excursions to the seagrass in the bay behind the institute. And our hosts Harald and Ragnild Asmus also to took us out to dinner to tast some of the local seafood. A wonderfull trip, enjoy the pictures!
