Organic matter characterization in the sea surface microlayers in the subarctic Norwegian fjords region
International audience The top of the ocean, sea surface microlayer (ML), covers more than 70% of the world's surface. It is a sink for natural and anthropogenic material that depends on its chemical composition. This article is aimed at providing novel data on the characterization of organic m...

International audience The top of the ocean, sea surface microlayer (ML), covers more than 70% of the world's surface.
