Thursday October 17 we had our annual excursion to the Sulfter on Texel to collect microbial mats for our master course Microbial Ecology.

The students, Henk Bolhuis, Linda Amaral-Zettler and me looking at microbial mats that produced a lot of oxygen.
Henk Bolhuis explaining the ins and outs of microbial mats on the beautiful isle of Texel.
