Soil salinity at GCE-LTER vegetation monitoring plots in October 2015

Soil samples were collected in conjunction with Fall 2015 plant monitoring at half of the permanent vegetation monitoring plots in the creekbank and midmarsh zones at 10 GCE study sites. Pore-water salinity was determined by analysis of supernatant salinity in dried soil samples hydrated with a measured volume of deionized water.

本研究于2015年秋季植物监测期间同步开展土壤样本采集工作，在10个GCE研究站点的溪岸带与中沼泽带的永久性植被监测样地中，选取半数样地进行采样。孔隙水盐度的测定方法为：将烘干后的土壤样本用定量体积的去离子水进行水化处理，随后分析其上清液的盐度。
