Seawater barium removal enhanced marine habitability for Cambrian animals
This study, led by Dr. Wei Wei, PhD student Lin-Hui Dong, and Prof. Fang Huang at the University of Science and Technology of China, investigates the removal of excess barium and sulfide from seawater and its impact on marine habitability during the Cambrian Explosion. Lin-Hui Dong analyzed excess barium contents (Baexcess) and isotope compositions (d138Baexcess) at the State Key Laborator
