Question
In salt marshes and mangroves, there is a large production of hydrogen sulfide and iron sulfide (pyrite and marcasite).
Why?
What consequences would this have on plant growth and productivity?
What wetland-plant adaptations would allow for survival under these conditions?
Salt marsh hydrology is often defined by near constant saturation in the middle of the marsh (where high tides during full and new moons recharges and where ET is low) and very high fluctuations along tide creeks, with water falling and rising with the tides.
Why does the water table fluctuate near the creeks like this?
Would you expect sulfide and pyrite production to be higher in the interior or along creeks?
Where would productivity be higher: in the interior or along the creeks? Why?
