Particles in the ocean are key mediators in the global and marine biogeochemical cycles of many elements including carbon and trace elements. Over the last 10 years, we have sampled and analyzed the first full ocean depth sections of size-fractionated particle mass and chemical composition from the Atlantic, the Pacific, and the Arctic Oceans as part of the GEOTRACES program. I’ll give an overview of the distribution, size partitioning, and composition of particles in these three ocean basins, and discuss some of the implications for quantifying particle dynamics and flux.
