EES Student Yi Tang and Professor Gillian Stewart published a paper in Deep Sea Research Part I: Oceanographic Research Papers entitled The influence of particle concentration and composition on the fractionation of 210Po and 210Pb along the North Atlantic GEOTRACES transect GA03. Congratulations Yi! Article highlights include: Provide links between particle features and 210Po and 210Pb activities in N. Atl. Particle characteristics, relationships with isotopes varied geographically. Particle characteristics, relationships with isotopes varied with particle size. Particle composition, especially litho and opal, could predict sorption of 210Pb. Sorption of 210Po is more complicated, but consistently related to POC content.
