Water level measurements on a southern Hog Island marsh, April-July 2014

Water level recorded in a backbarrier marsh on Hog Island concurrent to marsh burial experiment. HOBO Water level loggers (Model U20L-004) were placed just outside the plot at the two experimental sites in the high marsh and low marsh to record water level every 15 minutes. The loggers were suspended from steel wire at a constant elevation inside slotted PVC wells that allow water to flow through without allowing sediment infilling. Pressure measurements were then converted to water level using concurrently measured barometric data from Phillips Creek Marsh (accessible through data set: VCR12201).本数据集记录了霍格岛（Hog Island）障后潮沼在同步开展潮沼掩埋实验期间的水位监测数据。研究人员在高潮沼与低潮沼两处实验样地的样方外侧，布设了HOBO水位记录仪（HOBO Water level loggers，型号U20L-004），以每15分钟一次的频率采集水位数据。该记录仪通过钢丝悬挂于带槽聚氯乙烯（PVC）井内的固定高度处，该井体可允许水流进入同时避免沉积物淤积。随后，研究人员利用同期从菲利普斯溪潮沼（Phillips Creek Marsh）获取的气压数据（可通过数据集VCR12201获取），将测得的压力值转换为最终的水位数据。
