We present a Rare Earth Elements (REE) record determined on the EPICA ice core drilled at Dronning Maud Land (EDML) in the Atlantic sector of the East Antarctic Plateau. The record covers the transition from the last glacial stage (LGS) to the early

Aerosol reference materials available today are discussed with respect to the requirements of X-ray analytical techniques. The lack of a proper reference material for this purpose, which would consist of real aerosol collected onto filter membranes,

For the elemental analysis of aerosol filter samples by X-ray techniques there is a lack of adequate reference materials (RM). No genuine aerosol matrix is available, which has been collected on membrane filters from ambient aerosol and can be distri

Within the last decade, understanding of the biogeochemistry of trace metals in the marine environment has increased considerably. At the beginning of the 1980s, reliable sampling and analytical techniques became available to detect the relatively lo
