Dr. Dan Breecker is awarded an NSF Earth Science Postdoctoral Fellowship to carry out a program of research and education at the University of Arizona. Dr. Breecker will determine the concentration of CO2 during the precipitation of carbonate minerals in soils. The research goals will be accomplished by measuring CO2 concentrations, carbon isotopes, moisture and temperature in soils from different regions in Arizona, New Mexico, and Kansas; these soils have developed under different climate and vegetation conditions. These results will be used to calculate atmospheric CO2 concentrations in modern settings as well as to reconstruct paleoclimate models. This investigation will also provide information on how much CO2 soils can store in soils and it will contribute to the overall understanding of carbon cycle.In addition, Dr. Breecker will interact with high schools students by giving lectures on CO2 in the atmosphere and its role in the carbon cycle, engaging volunteer students in monitoring sampling sites, and assisting with science fair projects.

丹·布雷克（Dan Breecker）博士被授予NSF地球科学博士后研究金，以在亚利桑那大学进行研究和教育计划。 Breecker博士将在土壤中碳酸盐矿物沉淀过程中确定二氧化碳的浓度。研究目标将通过测量来自亚利桑那州，新墨西哥州和堪萨斯州不同地区的土壤中的二氧化碳浓度，碳同位素，水分和温度来实现；这些土壤在不同的气候和植被条件下发展。这些结果将用于计算现代环境中的大气二氧化碳浓度以及重建古气候模型。这项调查还将提供有关二氧化碳土壤可以在土壤中储存多少的信息，并将有助于对碳周期的整体理解。此外，布雷克（Breecker）博士将通过在大气中及其在碳循环中的二氧化碳讲座及其在碳循环中的作用，使志愿者在监测采样场所以及协助科学公平的项目中与高中生进行互动。
