Meri Korhonen, a member of the RAW project team, came to Wroclaw to help with the work necessary to conduct research on trace elements in water and on the surface of suspended particles.
Trace elements (e.g. Fe, Mn, Cu) may be a limiting factor for biological production, and related CO2 uptake, in glacier-fed waters.
Performing such analyses requires a number of preparatory works, which Meri Korhonen and Dr. Lukasz Stachnik performed in the laboratory of the Physical Geography Department of the Institute of Geography and Regional Development, University of Wroclaw. In particular, the membrane strainers had to be weighed, the sampling bottles rinsed with dilute hydrochloric acid and then with MilliQ water (which is ultrapure water with a negligible concentration of trace metals).
