Sandra Lagauzère

the best way would be to use vertical high-resolution gradients of SO4. By using microelectrodes (1-D) or DET/DGT gel probes (2-D).

Peter Striplin

We are in the process of using DGT gel probes to look at the migration of hydrogen sulfide in marine pore water. We are keeping our fingers crossed.
