When one tectonic plate dives beneath another at a subduction zone, it recycles huge amounts of water and other chemicals into Earth's mantle. The sinking plate carries seawater trapped in sediments and crust or chemically ...

The dynamics of nitrogen-based fertilizers in the root zone

Nutrient contamination of groundwater as a result of nitrogen-based fertilizers is a problem in many places in Europe. Calculations by a team of scientists led by the UFZ have shown that over a period of at least four months ...

Seismic signals allow researchers to see under river ice

River scientists from Sweden, Finland and Germany report detailed measurements of sediment movement and water level in an ice-covered river using a novel technique—seismic signals. The results are published in the Journal ...

Purifying water with the help of wood, bacteria and the sun
