Ocean Sciences 2026

MarChemSpec scientists David Turner and Simon Clegg will be present at the meeting in Glasgow, and available for discussions. They can be found at the Ocean Carbon and Biogeochemistry (OCB) booth in the Exhibition Hall on the Tuesday (10 – 11 am), and Wednesday (11 am to noon). Please email if you want to see us at some other time.

David’s poster OB14B-0473 describes a thorough update of our trace metal complexation model (Modelling the Inorganic Complexation of the GEOTRACES Core Elements From Freshwater to Seawater, Focusing on Hydroxide and Carbonate Ligands and a Revised Treatment of Fe(III) Hydrolysis).  The revised treatment of Fe(III) – hydroxide complexation is a particular focus, and has implications for ocean chemistry.

We are now updating the MarChemSpec software for the revised trace metal treatment, and this should be available for distribution in the spring of this year. Please contact us if you want to know more (s.clegg@uea.ac.uk, david.turner@marine.gu.se).

New Postdoc position available

We have a 2 year position at the University of East Anglia available now, to work on a model of pressure effects on the Tris buffers used to calibrate total pH for seawater measurements. The successful applicant will work with Simon Clegg using data from the literature and also results of new measurements being made at the UK’s National Oceanography Centre. The position is described here.
