New sulfide-films method published!

Check out our films method that was published in Marine Chemistry.

We demonstrate that photographic film can capture the spatial concentrations and stable isotope compositions of dissolved sulfide from water columns and pore waters. These films can be used in a wide variety of environments such as our study of the highly dynamic production and oxidation of hydrogen sulfide in the mud of the seagrass meadow shown below.
