Preliminary 14C Dating of Sedimentary Organic Matter from Glovers Park, NJ: Constraining the Timing of Atmospheric Carbon Dioxide and Methane Changes During the Last Deglaciation

[摘要]erickson， J. markst Lawrence大学，标题：新泽西州Glovers池塘沉积有机质的初步14C定年：限制末次冰期大气二氧化碳和甲烷变化的时间SGER奖支持从新泽西州西北部一个小泥沼湖的岩心中收集的大量有机质的AMS 14C定年。同位素数据提供了最后一次消冰期（18年）的详细、连续的环境记录。礼物)。这项研究将为这些同位素变化提供充分的时间覆盖。为了将陆地/湖泊记录与类似的欧洲湖泊记录、冰芯同位素、CO2和CH4数据以及海洋记录进行比较，需要更好的年龄约束。这项研究将有助于更好地了解在最后一次消冰期间大气成分发生的变化。T

AbstractATM-9819849Erickson, J. MarkSaint Lawrence UniversityTitle: Preliminary 14C Dating of Sedimentary Organic Matter from Glovers Pond, New Jersey: Constraining the Timing of Atmospheric Carbon Dioxide and Methane Changes During the Last DeglaciationThis SGER award supports AMS 14C dating of bulk organic matter collected from cores taken from a small marl lake in NW New Jersey. Isotope data provide a detailed, continuous environmental record of the last deglaciation ( 18 kyrs. to Present). This study will provide adequate temporal coverage of these isotopic changes. Better age constraints are needed to compare this terrestrial/lacustrine record with similar European lacustrine records, and ice core isotopic, CO2 and CH4 data and the marine record. This study will help to better understand the changes that occurred in atmospheric composition during the last deglaciation.T
