Coastal, Shelf, and Island Mass Effects on Trace Element Biogeochemistry in the Ocean

Session ID#: 254981

Session Description:
The marine biogeochemical cycles of trace elements, their stable isotopes compositions and organic binding ligands are affected by the island mass effects. With terrigenous, shelf and even glaciogenic inputs, islands are natural laboratories for studying the importance of lateral fluxes of trace elements, their impact on the physico-chemical processes and associated biological responses. This session aims to bring together researchers from diverse fields to discuss the latest findings on the biogeochemical processes occurring in the ocean and related to the island and shelf effects, from the coast to the open ocean. The aim is to improve our knowledge, identify biogeochemical impacts, and characterise physico-chemical speciation of metals and redox chemistry. We welcome research studies and experiments focusing on processes affecting trace metal chemistry, the nutrient cycle and organic ligands.
