Geological Record of Late Wiscon/Holocene Ice Sheet Advance and Retreat from Ross Sea

对罗斯海和威德尔海大陆架的海洋地质和地球物理研究提供了证据，表明在威斯康星晚期，这些地区的冰盖在大陆架边缘附近搁浅，冰盖退缩到现在的位置是迅速的，可能是断断续续的。该奖项支持一个项目，该项目将建立罗斯海最近（威斯康星州晚期-全新世）的冰盖进退历史。研究目标包括：1)重建威斯康辛州晚期古水系，包括冰流分水岭；2)原接地区位置重建；3)冰原退缩时间的约束；4)获取地球物理、沉积学和古生物学数据，为可能影响冰盖退缩的环境因素提供指示。这是莱斯大学、科罗拉多大学和汉密尔顿学院的共同努力。该项目涉及各个领域的专家，并将与冰川学家，物理海洋学家和气候学家进行交流，他们将解决冰盖稳定性问题以及气候和冰川变化的记录。

Marine geological and geophysical studies of the Ross Sea and Weddell Sea continental shelves provide evidence that the ice sheet grounded near the shelf edge in these areas during the late Wisconsinan, and that the retreat of the ice sheet to its present position was rapid and probably episodic. This Award supports a project which will establish the most recent (late Wisconsin-Holocene) history of ice sheet advance and retreat in Ross Sea. The objectives include: 1) reconstruction the late Wisconsin paleodrainage regime, including ice stream drainage divides; 2) reconstruction of former grounding zone positions; 3) constraint of the timing of ice sheet retreat from the shelf; and 4) acquisition of geophysical, sedimentological, and paleontological data which may provide indicators of the environmental factors that may have influenced to ice sheet retreat. This is a joint effort between Rice University, the University of Colorado, and Hamilton College. The project involves experts in a wide variety of fields, and will interface with glaciologists, physical oceanographers, and climatologists who will address the problem of ice sheet stability and the record of climatic and glaciological change.
