Marsh Ecology Research Program (MERP): Soil nutrients and groundwater well site characterization data (1980-1985)

The Marsh Ecology Research Program (MERP) was a long-term interdisciplinary study on the ecology of prairie wetlands. A scientific team from a variety of disciplines (hydrology, plant ecology, invertebrate ecology, vertebrate ecology, nutrient dynamics, marsh management) was assembled to design and oversee a long-term experiment on the effects of water-level manipulation on northern prairie wetlands. Ten years of fieldwork (1980 -1989), combining a routine long-term monitoring program and a series of short-term studies, generated a wealth of new and diverse information on the ecology and function of prairie wetlands (Murkin, Batt, Caldwell, Kadlec and van der Valk, 2000). This data set includes soil nutrient and site vegetation characetization data for all groundwater well sites. The main objective for monitoring soil nutrients in the MERP was to quantify sediments as a nutrient pool in wetlands and to characterize the sediments of the MERP cells over time. Along with monitoring the other major nutrient pools (surface water, plants and plant litter, animals and interstitial waters), yearly changes in the sediment nutrient pool can provide important information on the nutrient cycling within wetlands. In addition, the effects of deep flooding and drawdown on nutrients in marsh sediments was also evaluated (Kadlec, 1985a; Kadlec, 1985b; Kaldec, 1989).

沼泽生态研究计划（Marsh Ecology Research Program, MERP）是一项针对草原湿地生态的长期跨学科研究。由多学科领域（水文学、植物生态学、无脊椎动物生态学、脊椎动物生态学、营养动力学、沼泽管理学）的科研团队牵头，设计并监管了一项针对北部草原湿地水位调控效应的长期实验。该项目历经1980年至1989年十年野外工作，结合常规长期监测计划与一系列短期研究，产出了大量关于草原湿地生态与功能的全新多元研究成果（Murkin、Batt、Caldwell、Kadlec与van der Valk，2000）。

本数据集涵盖所有地下水井点位的土壤养分与样地植被特征数据。MERP中土壤养分监测的核心目标，是将沉积物作为湿地养分库进行量化，并长期刻画MERP实验单元沉积物的特征变化。结合对其他主要养分库（地表水、植物与枯落物、动物以及间隙水）的监测，沉积物养分库的年度变化可为湿地内部养分循环研究提供关键信息。此外，研究还评估了深度淹水与水位下降对沼泽沉积物养分的影响（Kadlec，1985a；Kadlec，1985b；Kaldec，1989）。
