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.

该项目支持美国参与ROSSMAP项目，这是一个为罗斯海开发新的地球物理和地质图的国际极地年项目。根据该奖项，一名美国首席研究员合成了在美国南极计划的各种研究巡航中收集的海洋地震数据。这一区域对研究至关重要，因为它记录了西南极冰盖(WAIS)的形成和演化。WAIS的冰川消退是决定全球变暖导致海平面上升的最大不受限制的因素之一，了解WAIS的历史将改进其对高温反应的模型。该项目还提高了我们对该地区发生的构造过程的了解。罗斯盆地是西南极裂谷系统的一部分，该裂谷系统是地球上最大的裂谷系统之一，也可能是最鲜为人知的。这个系统的独特之处在于它的一侧被一条山脉--横贯北极的山脉所包围。更广泛的影响是与意大利和新西兰的科学家进行国际合作，研究生的参与，以及开发一个可上网的数字数据库。
