Productivity Proxies in Surface Sediment of the East Antarctic Margin: A Focus on Excess Ba Paleoceanography and Paleoclimatolgy, 2024 (Ref: 17171)
Authors:

Category 1: Peer-reviewed literature

Components such as organic carbon (Corg), carbonate, opal or barite are valuable paleoceanographic proxies, enabling the reconstruction of past changes in carbon cycling under various climate regimes, particularly when 230Th-normalization is used to reconstruct particulate vertical rain rates.

Dissolved iron release by sediment and dust particles in Antarctic seawater greater than glacial flour and sea-ice particles Marine Chemistry, 2025 (Ref: 17275)
Authors:
Corkill M.Meiners K.M.Wongpan P.van der Merwe P.Creac'h L.Feig S.Nelson T.Smith A.J.R.Townsend A.T.Twiname S.Lannuzel D.
Category 1: Peer-reviewed literature

Primary productivity by phytoplankton in the Southern Ocean can be limited by low iron concentrations. Iron limitation in the surface ocean around Antarctica may be alleviated by particle dissolution of dust from exposed rock, glacial flour, resuspended marine sediment, and sea ice. Ligands…
