GEOTRACES Online Seminar #5 – 29 September 15:00 CEST

Topic: Biogeochemical Cycling of Redox-Sensitive Metals in Oxygen Minimum
Date: September 29th, 15:00 CEST
Moderator: Dr. Yang Xiang (Louisiana State University, USA)

Title: The dynamics of cross-shelf transport in eastern boundary regimes
Speaker: Prof. James W Moffett (Professor at the University of Southern California, USA)
Abstract: Continental margins are an important source of trace elements and isotopes to the interior of ocean basins involving a combination of benthic fluxes, fluvial sources and physical processes.  The analysis of multiple isotope tracers and metals within GEOTRACES,  combined with Regional Ocean Modeling System (ROMS) models have provided critical insight into cross-shelf transport.  

Title: Organic complexation of dissolved manganese(III) in hypoxic coastal waters
Speaker: Jessalyn E. Davis (PhD candidate at the University of Washington, USA)
Abstract: The oxidation state of manganese (Mn) in seawater dictates its potential reaction pathways and thus its interactions in the biogeochemical cycling of other trace elements. In this talk, I will highlight advancements in the characterization of the organic Mn pool and discuss how differing oxygen regimes impact the stabilization of dissolved Mn(III) in the Gulf of Mexico.
