From Ocean to Climate – tree papers published in Marine Chemistry

As a result of the Workgroup (139) funded by the Scientific Committee for Oceanographic Research (SCOR), a special issue has just been published in Marine ChemistrySCOR WG 139: Organic Ligands – A Key Control on Trace Metal Biogeochemistry in the OceanEdited by S. Sander, K. Buck and M. Lohan.

The Workgroup aim was to improve scientists' understanding of the role of organic metal-binding ligands in oceanic biogeochemistry through an interdisciplinary collaboration of members comprising trace metal biogeochemists, organic geochemists, and biogeochemical modelers.

Organic metal-binding ligands control the bioavailability of trace metals and thus influence pivotal global elemental cycles, such as those of carbon and nitrogen. To date, the sources, chemical structures, and degradation mechanisms of organic metal-binding ligands are still not well understood, making it difficult to model them with sufficient confidence to predict how they, and consequently trace metal cycles, will respond to projected global alteration of continental aridity (dust supply), ocean acidification, and oceanic oxygen minimum zones due to a changing climate.”

Despite SCOR funding ended, the scientific community gathered is still active and the website will be updated with critical information and databases, so keep your eyes open.

The Marine and Lake Biogeochemistry and the Institut F.-A. Forel participated in this working group and contributed with 3 scientific articles in this special issue:

The relevance of ligand exchange kinetics in the measurement of iron speciation by CLE–AdCSV in seawater

Iron associated with exopolymeric substances is highly bioavailable to oceanic phytoplankton

The role of bacterial and algal exopolymeric substances in iron chemistry
