Organic matter characterization in the sea surface microlayers in the subarctic Norwegian fjords region

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 matter in ML and underly...
