Collaborative research: Greenhouse gas balance of urban temperate wetlands

该项目的目标是测量湿地的温室气体（GHG）排放量，并量化天气、植被结构和水位动态对湿地系统GHG预算组成部分的影响。要做到这一点，将采用实验和建模任务的组合。 两个不同的城市温带湿地生态系统，一个在俄亥俄州，淡水湿地，和一个在新泽西，潮汐盐沼，将进行研究。 方法结合联合收割机直接测量的CO2和CH 4在空气中的两个湿地系统，测量室中的CH 4排放量，并测量湿地植被结构和生态生理学的背景下，现有的生物圈-大气模型。由于两个被调查的湿地已经建造或恢复，生态工程的各个方面将评估其对温室气体排放的影响。 在湿地收集的数据将用于生态系统模型中温室气体排放模块的参数化。 这可以作为一种规划工具，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。作为候选人，两名参加路易斯·斯托克斯少数民族参与联盟（LSAMP）的本科生将通过该项目接受气候变化科学方面的培训。汉密尔顿6/29/10

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.
