Iron deficiency restrains marine microbes

19.05.2017/Kiel. Iron is a critical nutrient in the ocean. Its importance for algae and the nitrogen cycle has already been investigated in detail. Now a new discovery shows that microbes also need iron to process phosphorus. A team of researchers from the GEOMAR Helmholtz Centre for Ocean Research ...

Methane Seeps off Svalbard reduce Greenhouse Effect

8 May 2017 / Kiel. Large quantities of the greenhouse gas methane are enclosed in the seafloor of the Arctic seas. According to the current opinion, this methane could speed up the global warming if it leaks out of the seafloor and reaches the atmosphere. However, an international research team in c...

The Kiel Fjord – a training pool for blue mussels

27 April 2017 / Kiel. Blue mussels are able to adapt to ocean acidification through evolution. In a common garden experiment, specimens from the Kiel Fjord were less sensitive to increased carbon dioxide concentrations than their relatives from the North Sea. According to a team of scientists from G...
