Marine Particle Chemistry: Influence on Biogeochemical Cycles and Particle Export
ACS Earth and Space Chemistry
Editors: Hilary G. Close, Phoebe J. Lam, and Brian N. Popp
Marine particles play a key role in the cycling of most elements in the ocean. Particles are typically operationally defined by their collection method and, therefore, span a wide size range, within which chemical properties and interactions may be heterogeneous. The papers in this collection address the challenges associated with studying particles in the marine environment with new types of chemical measurements, broadened oceanographic surveys, and novel sampling, experimentation, and modeling methods. Together, this collection of papers helps to fill critical gaps in our knowledge of the role of particles and elements in marine biogeochemical cycles.
Six papers in this collection report on results from the GEOTRACES programme, including the distributions of particulate trace elements (pTE) in snow, offshore pack ice, and surface waters in the Western Arctic (2), export fluxes of Hg from the Arctic (3) and pTE from the North Atlantic (4), the interplay of dissolved and particulate Fe at the Peru margin (5) and Nd concentrations and isotopic composition in the Western North Atlantic (6), and the solid-state chemical speciation of long-range hydrothermal particulate Fe (7):
