Collaborative Research: Glacial Marine Stratigraphy in the Eastern Ross Sea and Western Marie Byrd Land, and Shallow Structure of the West Antarctic Rift

该奖项支持加州大学圣巴巴拉分校和阿拉巴马大学合作的海洋地质和地球物理项目，以研究罗斯海东部和西南极玛丽·伯德陆缘的冰川和构造历史。该项目的目标是(1)进行地震成像和活塞取芯，以开始解开该区域最近大陆架沉积物中记录的西南极冰盖的历史，以及(2)获取新生代冰川沉积下的声学基底的地震图像，以了解该区域大陆地壳的裂谷结构与该区域新生代冰川沉积之间的关系。这项研究将产生罗斯海东部和马里伯德陆地边缘的水深、构造、沉积物等厚、重力和磁力地图。这些信息将被纳入对该区域主要冰川和构造特征的解释中。该项目将有助于更好地了解罗斯海东部和马里伯德陆缘的冰海地层和冰川历史，因此，它将对西南极冰盖倡议的目标作出重大贡献。

This award supports a collaborative marine geological and geophysical project between the University of California, Santa Barbara, and the University of Alabama to study the glacial and tectonic history of the eastern Ross Sea and the Marie Byrd Land margin of West Antarctica. The goals of the project are (1) to conduct seismic imaging and piston coring to begin unraveling the history of the West Antarctic ice Sheet as recorded in the recent sediments of the continental shelf of the region, and (2) to acquire seismic images of the acoustic basement beneath the Cenozoic glacial deposits toward an understanding of the relationship between rift structure of the continental crust and Cenozoic glacial deposits of the region. This research will result in bathymetric, structural, sediment isopach, gravity and magnetic maps of the eastern Ross Sea and the Marie Byrd Land margin. This information will be integrated into an interpretation of the major glacial and structural features of the region. This project will result in a better understanding of the glacio-marine stratigraphy and glacial history of the eastern Ross Sea and Marie Byrd Land margin and, consequently, it will represent a significant contribution to the goals of the West Antarctic Ice Sheet initiative.
