沿 5 条短样线对孔隙水化学和植物高度进行了检查，这些短线从以普通芦苇为主的潮汐沼泽部分延伸到以互花米草为主的部分。沿着 5 个横断面中的 4 个横断面，在相对较高的潮汐高度处发现了芦苇；沿着所有样带，芦苇在 12 至 30 ppt 的孔隙水盐度范围内生长和开花。在沼泽的大米草和芦苇区，溶解的无机磷浓度从 0 变化到>35 μM，但在以大米草和芦苇为主的区域，铵浓度平均>40 μM。
Porewater chemistry and plant height were examined along 5 short transects extending from sections of tidal marsh dominated by the common reed Phragmites australis to these dominated by Spartina alterniflora. Phragmites was found at relatively higher tidal elevations along 4 of 5 transects; along all transects, Phragmites was growing and flowering throughout a porewater salinity range from 12 to 30 ppt. Dissolved inorganic phosphorus concentrations varied from 0 to >35 mu M in both Spartina and Phragmites sections of marsh, but ammonium concentrations averaged >40 mu M in zones dominated by Spartina and
