- The genomes offer insights into microbial contributions to volatile compound production in the Southern Ocean.

## Abstract

We provide high-quality metagenome-assembled genomes (MAGs) derived from seawater and sea ice samples collected in the Southern Ocean. Several MAGs encode genes associated with dimethylsulfoniopropionate (DMSP) lyase activity and methane oxidation. This resource provides insights regarding the role of microbial communities in the production of key volatile compounds.
