Solid-phase extractable dissolved organic matter (SPE-DOM) molecular and structural properties remain unchanged during Weddell Sea dense-water formation, with the dominant Weddell Sea Deep Water (WSDW) signature set before shelf mixing.
- Why it matters: Antarctic Bottom Water (AABW) is shrinking under climate change, potentially altering abyssal carbon storage; knowing how shelf DOM is transformed and exported is essential.
- What they did: The study examined SPE-DOM transformations in the Weddell Sea and compared molecular/structural properties across dense-water formation and shelf export, estimating annual carbon transfer of 0.155 ± 0.03 PgC.
- The result: Shelf processes minimally affect exported organics into the deep sea, implying SPE-DOM composition is expected to stay conserved even as AABW weakens.
