21 December 2023 | Rafting of Growing Antarctic Sea Ice Enhances In-Ice Biogeochemical Activity in Winter

Riesna R. AudhSarah E. FawcettSiobhan JohnsonTokoloho RampaiMarcello Vichi


Key Points of the article:

  • We present the first biogeochemical data for young and growing sea ice in the Atlantic Antarctic marginal ice zone

  • Winter sea ice is biogeochemically active and acts as a reservoir of concentrated nutrients during the ice growth season

  • The biogeochemical signature of individual floes is conserved during rafting, leading to enhanced nutrients and chlorophyll-a in first-year sea ice
