Sediment samples from the North Sea.

Three elements in one sweep

Where does the sediment in the Wadden Sea and the silt in the harbour of Hamburg come from? How are pollutants in the environment distributed? Questions like these can, for example, be answered today though chemically analysing trace elements in sediment or water samples. These methods, however, are still often very time-consuming because the analysis samples must be processed with a great deal of effort. A HZG doctoral candidate, Tristan Zimmermann, has therefore developed a method that vastly speeds up sample preparation. His method will help ease everyday laboratory work for researchers all over the world. His endeavours have now been awarded a prize at a scientific conference. more

Paleoclimate – Learning from the Past

The future lies in the past. This statement may sound technically incorrect or, at best, like a paradox. For some scientists it is, however, one hundred percent accurate. They investigate periods in the past to better understand the “here and now”. more

Carbon Is Cleverly Joined with Metal: HZG Scientist Receives Henry Granjon Prize for New Methodology

Since 1948 the renowned International Institute of Welding (IIW) awards annually the most emerging young professionals and scientists award in the area of joining technology: the Henry Granjon Prize. On July 10th 2016, Dr. Seyed Goushegir is awarded this year’s prestigious prize at the IIW's 69th annual meeting in Melbourne. He received the prize for his work within the Institute of Materials Research at the Helmholtz-Zentrum Geesthacht.Geesthacht. more

Combined Ammonia and Shipping Emissions Favour Particulate Matter Formation Notably in Coastal Regions

Ammonia, mainly emitted in agriculture, increases the formation of certain particulate matter in the air, thus facilitating pollution in the coastal regions. Particle formation is especially efficient in combination with shipping emissions. One of the main sources of ammonia emissions is animal husbandry. Anna M. Backes and her colleagues in the Department of Chemistry Transport Modelling within the Institute of Coastal Research at the Helmholtz-Zentrum Geesthacht (HZG) have demonstrated in a model study that, by halving ammonia emissions, the notable concentration of particulate matter in parts of Europe is reduced by one quarter in winter. more
