Acquisition of Geophysical Instrumentation for Enhancing Peatlands Research and Training of a Diverse Student Population in New Jersey

这笔赠款支持购置近地表地球物理设备，以促进对北部泥炭地和北极沼泽的生物气藏和通量的研究。将购买的具体设备包括：1)手持式频域电磁系统；2)10通道时间域电阻率/激电系统；以及3)升级现有的探地雷达系统，以便同时收集工作在不同频率(100和200兆赫)的两个天线的数据。该设备将允许对北纬泥炭地的自由相气体(主要是甲烷气泡)进行更高的空间分辨率和时间序列地下成像。推动的研究将有助于更好地了解碳气体通量的时间控制和估计这些系统中可能因全球变暖而释放到大气中的古代碳库的储存量(人为温室气体排放产生的积极反馈)。该仪器将支持罗格斯大学纽瓦克分校和新泽西城市大学(NJCU)的本科生和研究生使用最先进的地球物理设备的体验，这两所大学都位于学生比例偏低的城市地区(NJCU是一家西班牙裔服务机构)。PI计划让学生参与受工业影响的地区性地下调查。

This grants supports acquisition of near surface geophysical equipment that will facilitate research on biogenic gas reservoirs and fluxes from northern peatlands and arctic bogs. Specific equipment to be purchased includes: 1) a handheld frequency-domain electromagnetic system; 2) a time-domain, 10 channel resistivity/induced polarization system; and 3) upgrade of an existing ground penetrating radar (GPR) system to allow for simultaneous collection of data from two antennas operating at different frequencies (100 and 200 MHz). The equipment will allow for higher spatial resolution and time-series subsurface imaging of free phase gas (primarily bubble pockets of methane) in northern latitude peatlands. Research facilitated will support a better understanding of the temporal controls of carbon gas fluxes and estimation of reservoirs of ancient carbon pools in these systems that are could be released to the atmosphere as a consequence of global warming (a positive feedback resulting from anthropogenic greenhouse gas emissions. The instrumentation will support undergraduate and graduate student experiences with state-of the-art geophysical equipment at both Rutgers University-Newark and New Jersey City University (NJCU), both located in urban areas with high percentages of underrepresented students (NJCU is a Hispanic Serving Institution). The PIs plan to involve students in industry-impacted regional subsurface investigations.
