"With this installation we’re trying to collect soil water samples. There’s a plate with a wick like in a candle, in the soil. This wick absorbs moisture in the soil and leads it through a tube into a bottle like this one. These water samples, we analyse for stable water isotopes and these can be used to estimate how long it takes before the rain eventually reaches the stream." – Suzanne Jacobs (CIFOR Intern and Postdoctoral Scientist, Justus Liebig Universitat, Giessen).
