METEOR M91

Our understanding of the air-sea exchange of oceanic trace gases has increased significantly within the past decade and increasingly researchers are realizing the importance of coastal upwelling regions for these exchanges to climate, local radiative balance, and biogeochemical processes. The aim of the Meteor cruise M91 is to conduct an integrated process study on the upwelling region off Peru in order to assess its importance for the emissions of various atmospheric trace gases and tropospheric chemistry.
For this it is planned to undertake a comprehensive measurement campaign that not only focusses on the ocean/atmosphere gas exchange, but also on the ocean biogeochemistry, atmospheric gas and aerosol fluxes as well as atmospheric and oceanographic processes in the upwelling region off Peru.
The M91 cruise is a contribution of the German BMBF joint project SOPRAN to the midterm strategy initiative ‘Air-sea gas fluxes at eastern boundary upwelling and oxygen minimum zones systems’ of the international SOLAS.
