Antarctic water analysis reveals unexpected stability in dissolved organic carbon
Researchers have analyzed water samples collected during two expeditions aboard the research icebreaker Polarstern to investigate how life and changing conditions on the Antarctic continental shelf affect carbon carried into the deep ocean. Published in Nature Communications, the study reveals a surprising finding: Despite intense biological activity and major changes in the water masses, the amount and make-up of dissolved organic matter remain…

Deep water is formed in the Weddell Sea, which transports large amounts of carbon into the deep sea. Despite active plankton production, the composition of the dissolved organic substances studied on the Antarctic shelf hardly changes, as measurements show. One possible explanation is the long dwell time of the water, while the easily degradable material can decay again. Bremerhaven (Germany). At the edge of Antarctica, particularly cold and sal…
