Hello, My name is Daniela Gorr and I am currently working on my diploma thesis at the Leibniz Institut in Hanover. The topic involves the determination of the composition of d18O and d13C in sediments of lake Mueritz (authigenic precipitated carbonates) in northern Germany. Therefore I am interested in 1. the isotopic composition (d18O) of the lake water, and 2. the isotopic composition (d18O) of the precipitation in that area Has anyone already done investigations near Mueritz or in an area nearby, or does anyone know literature/data(published/unpublished). Thank you for your time. Best regards, Daniela
