Their major advantages are a simple\, cost- effective analysis as well as a broad versatility. They have been applied to investigate groundwater-surface water interactions\, pore water fluxes across the sediment-water interface\, and dynamics of hydrothermal vent sy stems.\nIn the scope of this short introductory course\, we will review th e basics of radiochemistry\, explore the utility of the U-Th series radion uclides in geochronology and flux calcuations\, and establish an overview about analytical approaches and environmental applications. The course wil l include a field trip to Spiekeroog Island\, where samples will be collec ted and analyzed later at ICBM in Oldenburg.\nA background in (geo)chemist ry or radiochemistry is desirable\, but not required. However\, due to the limited space and time-intensive supervision\, this course is limited to 4 participants on a first-come-first-serve basis.
