Jan Tjalling van der Wal, Ecotoxicology researcher at Imares in Den Helder
In the summer Jan Tjalling van der Wal spends on average of almost one working day on the water. Pedalling away, enjoying the movement, the peace and the natural surroundings. ‘You get a different view of the environment from the water'. He kayaks for the fun of it. ‘I'm not competitive.' He is adventurous though. And sea-kayaking and wild water kayaking are ‘not for wimps'. They take some practice. Like here, at home on the slalom course on the Maarsseveense Plassen.
