Ocean interfaces under global changes –
Exploring the fate of the Amazon River plume

The Amazon River contributes to almost 20% of global riverine freshwater input to the ocean, supporting a diverse ecosystem. The plume helps removing carbon from the ocean waters which is most pronounced in the plume´s nitrogen limited zone. Constraining N transformations in this complex system is essential to understand the future of changing river systems entering the coastal ocean. For this purpose, the Meteor cruise M174 and the German Research Foundation funded MeNARP Project (Metabolism of N in the Amazon River Plume and Tropical North Atlantic) study the plume and western tropical North Atlantic between April 12 to May 31, with an interdisciplinary international team from Germany, Switzerland and the USA.

06.05.2021 – Using satellites to map the Amazon River Outflow and plan our sampling locations

The Amazon River outflow is so vast and dynamic that it is unrealistic to study the entire system using conventional ship-based observations only. Space-based satellites are ideal tools for observing such extended and quickly changing surface phenomena.
