Porewater profiles of reactive iron, sulfide and total alkalinity in mangrove...

Porewater Fe²⁺, FeTot and sulfide (S²⁻) were measured by spectrophotometry. The 1,10-phenanthroline method was used to determine porewater Fe²⁺ and, after reducing Fe³⁺ by...

Incubation experiments characterizing nitrate reduction in the water column o...

We performed incubation experiments with added nitrate (and additional sulfide or acetate) using water samples from the Lake Lugano North Basin, to determine the N and O isotope...

Profiles of N, Fe, Mn and S compounds - concentrations and isotopes in the wa...

We investigated the water column of the meromictic Lake Lugano North Basin, Switzerland, during 12 sampling campaigns between 2015 and 2018. At the deepest point of the lake, we...

Sequential iron extraction, pore water and solid phase analyses for sediment ...

Fe2+ was analysed photometrically (Hach Lange DR 5000 photometer) at 565 nm following the method of Collins et al. (1959). 1 mL of acidified sample (20 L of 1% ascorbic acid)...
