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之间的一个海洋地质和地球物理合作项目，该项目旨在研究罗斯海东部和南极洲西部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心，开始揭示该地区大陆架近期沉积物中记录的南极西部冰盖的历史；(2)获取新生代冰川沉积物下声学基底的地震图像，以了解大陆地壳裂谷结构与该地区新生代冰川沉积物之间的关系。这项研究将绘制出罗斯海东部和玛丽·伯德陆缘的水深、构造、沉积物等深线、重力和磁图。这些资料将被纳入对该地区主要冰川和构造特征的解释中。该项目将使人们更好地了解罗斯海东部和玛丽伯德陆缘的冰川-海洋地层学和冰川历史，因此，它将对南极西部冰盖倡议的目标做出重大贡献。

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.
