This project aims at a better understanding of the reaction of terrestrial coastal ecosystems to climate change between ~33 to ~13 million years before present. Palynological analyses will be used to reconstruct vegetation and climate development in the hinterland of the New Jersey Shallow shelf. Quantitative precipitation and temperature data for the terrestrial realm will be generated via the application of pollen-based methods of climate reconstruction. The vegetation and climate reconstructions for the terrestrial realm will be compared with local and global sea level- and climate changes. A direct comparison with conditions in the marine realm will be allowed by analyzing marine palynomorphs from the same samples. Research foci will be on the Eocene-Oligocene boundary, which was an interval of rapid global cooling, and on the Oligocene-Miocene boundary, which was characterized by an increase in atmospheric CO2, temperatures and sea level, and a decrease in continental ice sheets extend. In addition to the major aim, the project results will be important for the understanding of evolution and biogeographic development of the North-eastern American vegetation.

该项目旨在更好地了解距今约3300万年至约1300万年之间陆地沿海生态系统对气候变化的反应。孢粉学分析将用于重建新泽西州浅陆架腹地的植被和气候发展。通过应用基于花粉的气候重建方法，将生成陆地领域的定量降水和温度数据。陆地领域的植被和气候重建将与当地和全球海平面和气候变化进行比较。通过分析来自相同样品的海洋形态，可以与海洋领域的条件进行直接比较。研究重点将集中在始新世-渐新世边界，这是一个全球快速变冷的区间，以及渐新世-中新世边界，这是一个以大气CO2、温度和海平面增加、大陆冰盖扩大减少为特征的区间。除了主要目的之外，该项目的结果对了解美国东北部植被的进化和生物地理发展也很重要。
