Metal accumulation occurs concomitantly with sed- effects of salt marsh geomorphology on the distribution of imentary and hydrodynamic processes which impart a char- surface metal content. Surface sediment samples (46) were acteristic topographic structure to the salt marsh. Typically, taken along two transects across an intertidal salt marsh salt marshes are low gradient landscapes, with well devel- island. Abundance of Ca, Al, Fe, Ni, Cr, Cu, Zn, Rb, Sr, oped levees, intertidal creeks, and a broad platform with As, and Zr vary up to 300 % with
