Abstract:
Pore water for iron isotope analysis was collected by use of rhizons, acidified and stored at 4°C until processing onshore. Processing of pore water (purification and matching) was performed at the University of Cologne, and measurements were performed on a MC-ICPMS at the Steinmann Institute in Bonn.
