Seismic Stratigraphic Correlations Across Ross Sea for ROSSMAP: Paleoclimate and Tectonics

该项目支持美国参与国际极地年项目ROSSMAP，为罗斯海绘制新的地球物理和地质图。根据该奖项，美国首席研究员综合了美国南极计划各种研究巡航中收集的海洋地震数据。这一地区是研究的关键，因为它记录了西南极冰盖（WAIS）的形成和演变。WAIS冰川消退是决定伴随全球变暖的海平面上升的最大不受约束的因素之一，了解WAIS的历史将改善其对温度升高的反应模型。该项目还提高了我们对该地区发生的构造过程的理解。罗斯盆地是西南极裂谷系的一部分，是地球上最大的裂谷系之一，也许是人们了解最少的裂谷系。这个系统的独特之处在于一边是山脉，即横贯南极山脉。更广泛的影响是与意大利和新西兰科学家的国际合作，研究生的参与，以及开发一个网络访问的数字数据库。

AbstractThis project supports US participation in ROSSMAP, an International Polar Year project developing new geophysical and geologic maps for the Ross Sea. Under this award a US Principal Investigator synthesizes marine seismic data collected on various research cruises of the US Antarctic Program. This region is critical for study because it records the formation and evolution of the West Antarctic Ice Sheet (WAIS). WAIS deglaciation is amongst the largest unconstrained factors in determining the sea level rise that will accompany global warming, and understanding WAIS history will improve models of its response to elevated temperatures. This project also improves our understanding of tectonic processes that occurred in the region. The Ross basin is part of the West Antarctic Rift System, among the Earth's largest and perhaps the most poorly understood. This system is unique in being bounded on one side by a mountain range, the TransAntarctic Mountains. The broader impacts are international collaboration with scientists in Italy and New Zealand, graduate student participation, and development of a web-accessible digital database.
