Conserved molecular properties of dissolved organic matter during Weddell Sea Deep Water formation
Nature · By Gonzalo V. Gomez-Saez ·
The Brief
- A Nature Communications study reports that molecular properties of dissolved organic matter are conserved during dense-water formation in the Weddell Sea.
- The study indicates Antarctic shelf processes minimally affect dissolved organic matter during this process.
- The article was published online on 10 November 2026 with DOI 10.1038/s41467-026-79040-4.
Why it matters
Dissolved organic matter is a major carbon reservoir in the ocean, so knowing whether shelf processes alter its molecular makeup during deep-water formation helps constrain carbon cycling models for the Southern Ocean.
Who’s affected
- oceanographers and marine biogeochemists
