The goal of this project is to measure Greenhouse Gas (GHG) emissions from wetlands and quantify the effects of weather, vegetation structure, and water level dynamics on components of the GHG budget of the wetland systems. To do this a combination of experimental and modeling tasks will be employed. Two distinct urban temperate wetland ecosystems, one in Ohio, a freshwater wetland, and one in New Jersey, a tidal salt marsh, will be studied. Methods combine direct measurements of CO2 and CH4 in the air over the two wetland systems, measurements of CH4 emissions in chambers, and measurements of wetland vegetation structure and ecophysiology in the context of an existing biosphere-atmosphere model. As the two wetlands to be investigated have been constructed or restored, all aspects of ecological engineering will be assessed for their effects on GHG emissions. The data collected in the wetlands will be used to parameterize the GHG emission module in the ecosystem model. This can be used as a planning tool to predict GHG budgets in different climates, wetland designs, and management practices. In addition to two Ph.D. candidates, two undergraduate students participating in the Louis Stokes Alliances for Minority Participation (LSAMP) will be trained in climate change science through this project.Bruce K.

该项目的目的是测量湿地的温室气体（GHG）排放，并量化天气，植被结构和水位动力学对湿地系统温室气体预算组件的影响。为此，将采用实验和建模任务的组合。 将研究两个不同的城市温带湿地生态系统，一个在俄亥俄州，一个淡水湿地，一个在新泽西州，一个潮汐盐沼。 方法结合了两个湿地系统上的空气中二氧化碳和CH4的直接测量，在现有的生物圈 - 大气模型的背景下，室内CH4排放的测量以及湿地植被结构和生态生理学的测量。由于已经构建或修复了两个要研究的湿地，因此将评估生态工程的所有方面对温室气体排放的影响。 湿地中收集的数据将用于将生态系统模型中的温室气体发射模块参数化。 这可以用作计划工具，以预测不同气候，湿地设计和管理实践中的温室气体预算。 除了两个博士学位候选人，两名参加少数群体参与路易斯·斯托克斯联盟（LSAMP）的本科生将通过此项目接受气候变化科学的培训。
