TL;DR: The GEOTRACES Intermediate Data Product 2017 (IDP2017) as discussed by the authors is the second publicly available data product of the international GEOTrACES programme, and contains data measured and quality controlled before the end of 2016.

Natural iron fertilization by the Eyjafjallajökull volcanic eruption
Eric P. Achterberg,C. Mark Moore,Stephanie A. Henson,Sebastian Steigenberger,Andreas Stohl,Sabine Eckhardt,Lizeth C. Avendano,Michael Cassidy,Debbie Hembury,J. K. Klar,Mike Lucas,Anna I. Macey,Chris M. Marsay,Thomas J. Ryan-Keogh +13 more
TL;DR: Aerosol deposition from the 2010 eruption of the Icelandic volcano Eyjafjallajokull resulted in significant dissolved iron (DFe) inputs to the Iceland Basin of the North Atlantic as mentioned in this paper.
Journal ArticleDOI
Seasonal ITCZ migration dynamically controls the location of the (sub)tropical Atlantic biogeochemical divide
Christian Schlosser,J. K. Klar,Bronwyn Wake,Joseph T. Snow,David J. Honey,E. M. S. Woodward,Maeve C. Lohan,Eric P. Achterberg,Eric P. Achterberg,C. M. Moore +9 more
TL;DR: It is demonstrated that wet deposition in the region of the intertropical convergence zone acts as the major dissolved iron source to surface waters and that the underlying biogeochemical mechanisms would likely characterize the response of oligotrophic systems to altered environmental forcing over longer timescales.
Journal ArticleDOI
Stability of dissolved and soluble Fe(II) in shelf sediment pore waters and release to an oxic water column.

TL;DR: Modelling indicates significant diffusive fluxes of Fe(II) (on the order of 23–31 µmol m−2 day−1) are possible during late spring when oxygen penetration depths are shallow, and pore water Fe(I) concentrations are highest, and oxic continental shelves can supply dFe to the water column.
Journal ArticleDOI
Behaviour of chromium isotopes in the eastern sub-tropical Atlantic Oxygen Minimum Zone
Heather J. Goring-Harford,J. K. Klar,J. K. Klar,Christopher R. Pearce,Douglas P. Connelly,Eric P. Achterberg,Rachael H. James +6 more
TL;DR: In this article, the authors presented dissolved chromium (CrT) concentrations for shelf, slope and open ocean waters within the oxygen minimum zone (OMZ) of the eastern sub-tropical Atlantic Ocean.
